How to Write and Deploy Modular Smart Contracts Modular contracts enable highly configurable and upgradeable smart contract development, combining ease of use with security. They consist of two main components:Core Contracts: These form the foundation of the modular system, managing key functions, data storage, and logic. Core contracts include access control mechanisms and define interfaces for module interactions.Module Contracts: These add or remove functionalities to/from core contracts dynamically, allowing for flexibility. Modules can be reused across multiple core contracts, enabling upgrades without redeploying the core contract.How They Work: Modules provide additional functionality via callback and fallback functions that interact with core contracts. Fallback functions operate independently, while callback functions augment core contract logic, enhancing dApp functionality.You may also like | How to Create Play-to-Earn Gaming Smart ContractsSetup | Writing and Deploying Modular Smart ContractsInstall Forge from Foundry and add the modular contract framework:forge init forge install https://github.com/thirdweb-dev/modular-contracts.git forge remappings > remappings.txt ContractThe ERC20Core contract is a type of ERC20 token that combines features from both the ModularCore and the standard ERC20 contract. It names the token "Test Token" and uses "TEST" as its symbol, with the deployer being the owner of the contract. A significant feature is the required beforeMint callback, which allows certain actions to be taken before new tokens are created. The mint function lets users create tokens while ensuring the callback is executed first. The BeforeMintCallback interface makes it easier to add custom logic from other contracts. Overall, ERC20Core offers a flexible way to develop custom tokens while maintaining essential ERC20 functions.// SPDX-License-Identifier: UNLICENSED pragma solidity ^0.8.13; import {ModularCore} from "lib/modular-contracts/src/ModularCore.sol"; import {ERC20} from "lib/solady/src/tokens/ERC20.sol"; contract ERC20Core is ModularCore, ERC20 { constructor() { _setOwner(msg.sender); } function name() public view override returns (string memory) { return "Test Token"; } function symbol() public view override returns (string memory) { return "TEST"; } function getSupportedCallbackFunctions() public pure virtual override returns (SupportedCallbackFunction[] memory supportedCallbacks) { supportedCallbacks = new SupportedCallbackFunction[](1); supportedCallbacks[0] = SupportedCallbackFunction(BeforeMintCallback.beforeMint.selector, CallbackMode.REQUIRED); } function mint(address to, uint256 amount) external payable { _executeCallbackFunction( BeforeMintCallback.beforeMint.selector, abi.encodeCall(BeforeMintCallback.beforeMint, (to, amount)) ); _mint(to, amount); } } interface BeforeMintCallback { function beforeMint(address to, uint256 amount) external payable; } Also, Read | ERC 4337 : Account Abstraction for Ethereum Smart Contract WalletsThe PricedMint contract is a modular extension designed for token minting, leveraging Ownable for ownership management and ModularExtension for added functionality. It uses the PricedMintStorage module to maintain a structured storage system for the token price. The owner can set the minting price through the setPricePerUnit method. Before minting, the beforeMint function verifies that the provided ether matches the expected price based on the token quantity. If correct, the ether is transferred to the contract owner. The getExtensionConfig function defines the contract's callback and fallback functions, facilitating integration with other modular components.// SPDX-License-Identifier: UNLICENSED pragma solidity ^0.8.13; import {ModularExtension} from "lib/modular-contracts/src/ModularExtension.sol"; import {Ownable} from "lib/solady/src/auth/Ownable.sol"; library PricedMintStorage { bytes32 public constant PRICED_MINT_STORAGE_POSITION = keccak256(abi.encode(uint256(keccak256("priced.mint")) - 1)) & ~bytes32(uint256(0xff)); struct Data { uint256 pricePerUnit; } function data() internal pure returns (Data storage data_) { bytes32 position = PRICED_MINT_STORAGE_POSITION; assembly { data_.slot := position } } } contract PricedMint is Ownable, ModularExtension { function setPricePerUnit(uint256 price) external onlyOwner { PricedMintStorage.data().pricePerUnit = price; } function beforeMint(address to, uint256 amount) external payable { uint256 pricePerUnit = PricedMintStorage.data().pricePerUnit; uint256 expectedPrice = (amount * pricePerUnit) / 1e18; require(msg.value == expectedPrice, "PricedMint: invalid price sent"); (bool success,) = owner().call{value: msg.value}(""); require(success, "ERC20Core: failed to send value"); } function getExtensionConfig() external pure virtual override returns (ExtensionConfig memory config) { config.callbackFunctions = new CallbackFunction ; config.callbackFunctions[0] = CallbackFunction(this.beforeMint.selector); config.fallbackFunctions = new FallbackFunction ; config.fallbackFunctions[0] = FallbackFunction(this.setPricePerUnit.selector, 0); } } DeployTo deploy the Modular Contract, first get your API Key from the Thirdweb Dashboard. Then run npx thirdweb publish -k "THIRDWEB_API_KEY", replacing "THIRDWEB_API_KEY" with your key.

ERC 4337 : Account Abstraction for Ethereum Smart Contract Wallets Understanding Account Abstraction on Ethereum for Smart Contract WalletsA novel concept in blockchain, account abstraction aims to improve and harmonize user account functionality in decentralized systems. Contract wallets, also known as smart contract accounts, can replace traditional externally held accounts thanks to account abstraction and smart contract development. A contract wallet can be controlled by a single key, multiple keys, or even a complex system encoded into the contract itself. This opens up numerous possibilities and benefits for Ethereum and other blockchain networks. Account abstraction allows for more flexible and secure management of contract wallets compared to traditional externally held accounts. For more about blockchain, Ethereum, and smart contracts, visit our smart contract development services.In the Ethereum network, two types of accounts currently exist:Externally Owned Accounts (EOAs): controlled by private keys and typically of specific people or organizations.Contract Accounts: smart contracts whose code is run according to predetermined logic.Account abstraction seeks to unify the two types of Ethereum accounts:This implies that smart contracts can now manage and carry out transactions on behalf of users rather than exclusively depending on private keys (as with EOAs), providing users with more flexibility and opening the door to new features like customizable security models, automated and gasless transactions, meta-transactions, and improved privacy. These developments streamline user interactions and increase the Ethereum ecosystem's potential.Also, Read | How to Create an NFT Rental Marketplace using ERC 4907Why do we need Account Abstraction ?The current configuration of the Ethereum network has several drawbacks:Security Risks: Due to their binary structure, private keys can be lost or stolen, which can result in an irreversible loss of money.User Experience: For new users who could find wallet security and gas principles confusing, EOAs demand private keys and gas costs in Ether, which causes friction.Hazards to Security: Due to their binary structure, private keys can be lost or stolen, which can result in an irreversible loss of money.Limited Features: Advanced features like multi-signature wallets and daily transaction restrictions cannot be implemented on EOAs due to their lack of programmability.By addressing these problems, account abstraction seeks to enhance the functionality, security, and usability of the network.Also, Read | A Guide to Implementing NFT Royalties on ERC-721 & ERC-1155Approaches to Implement Account Abstraction:Protocol-Level ChangesIt entails modifying the Ethereum protocol to allow native wallets for smart contracts. Consensus is required for this strategy throughout the Ethereum network.Layer 2 SolutionsLayer 2 networks provide the ability to offload transaction processing and implement unique transaction validation procedures.ERC 4337 (Ethereum Request for Comments)It suggests implementing account abstraction just at the application level, eliminating the need for protocol modifications.Also, Read | How to Create and Deploy a Token Bound Account | ERC-6551What is ERC 4337?A new transaction handling mechanism called UserOperation objects is introduced in ERC 4337. By signing UserOperation objects, which bundlers aggregate and transmit to the network, users avoid submitting transactions straight to the Ethereum blockchain. Without relying on the current transaction flow, this method enables smart contract wallets to safely start transactions. Implementation of ERC 4337:A number of essential elements are involved in the Solidity implementation of ERC 4337 (Account Abstraction), which combined allow for flexible and intuitive interactions with smart contracts. These are the primary elements to pay attention to:1. UserOperation StructPurpose: Represents a single user operation with all necessary information.Key Fields:sender: The address of the user or wallet executing the operation.nonce: To prevent replay attacks and track the order of operations.callData: The encoded data for the function call.gasLimit: The maximum amount of gas that can be used for the operation.maxFeePerGas & maxPriorityFeePerGas: Control over gas fees.You may also like | How to Create an ERC 721C Contract// SPDX-License-Identifier: MIT pragma solidity ^0.8.0; contract UserOperationExample { struct UserOperation { address sender; // Address of the user sending the operation uint256 nonce; // Unique nonce to prevent replay attacks bytes callData; // Encoded data for the function call uint256 gasLimit; // Maximum gas limit for the operation uint256 maxFeePerGas; // Maximum fee per gas unit the user is willing to pay uint256 maxPriorityFeePerGas; // Max priority fee per gas } // Example function to demonstrate the use of UserOperation function exampleFunction(UserOperation calldata userOp) external { // Validate the user operation (you would typically check nonce, gas limits, etc.) require(userOp.sender != address(0), "Invalid sender"); require(userOp.gasLimit > 0, "Gas limit must be greater than zero"); // Here you would implement the logic to execute the operation (bool success, ) = userOp.sender.call{gas: userOp.gasLimit}(userOp.callData); require(success, "Operation failed"); // You could also emit an event here for tracking purposes } }Also, Discover | How to Create and Deploy an ERC404 token contract2. EntryPoint ContractPurpose: Central contract that receives user operations and executes them.Key Functions:executeUserOperation: Validates and executes the user operation, checking the sender's nonce, ensuring gas limits, and processing the call data.Security Checks: Implement checks to prevent issues like underflow/overflow, invalid addresses, and ensure gas payment.// SPDX-License-Identifier: MIT pragma solidity ^0.8.0; contract EntryPoint { event UserOperationExecuted(address indexed sender, bytes callData); event UserOperationFailed(address indexed sender, bytes callData, string reason); // This mapping tracks the nonce for each user to prevent replay attacks mapping(address => uint256) public nonces; function executeUserOperation(UserOperation calldata userOp) external { // Validate the user operation require(userOp.sender != address(0), "Invalid sender"); require(userOp.nonce == nonces[userOp.sender], "Invalid nonce"); require(userOp.gasLimit > 0, "Gas limit must be greater than zero"); // Update the nonce nonces[userOp.sender]++; // Execute the operation (bool success, bytes memory returnData) = userOp.sender.call{gas: userOp.gasLimit}(userOp.callData); if (success) { emit UserOperationExecuted(userOp.sender, userOp.callData); } else { emit UserOperationFailed(userOp.sender, userOp.callData, _getRevertMsg(returnData)); } } // Helper function to extract revert reason function _getRevertMsg(bytes memory returnData) internal pure returns (string memory) { if (returnData.length < 68) return "Transaction reverted silently"; assembly { returnData := add(returnData, 0x04) } return abi.decode(returnData, (string)); } }Also, Discover | ERC 3643 A Protocol for Real World Asset Tokenization3.

By offering a means of verifying and carrying out these procedures, it guarantees that activities may only be carried out by authorized users. // SPDX-License-Identifier: UNLICENSED pragma solidity ^0.8.9; import "./library/UserOperation.sol"; import "@openzeppelin/contracts/utils/cryptography/ECDSA.sol"; contract AbstractedAccountWallet { using ECDSA for bytes32; uint256 public constant SIG_VALIDATION_FAILED = 1; uint256 public constant NONCE_VALIDATION_FAILED = 2; uint256 public constant VALIDATION_SUCCESS = 0; address public owner; uint256 public nonce; address public entryPoint; // Events for logging important actions event ExecutedOperation(address indexed sender, uint256 value, bytes data); constructor(address _entryPoint) { owner = msg.sender; nonce = 0; entryPoint = _entryPoint; } // Modifier to check if the caller is the owner of the contract modifier onlyOwner() { require(msg.sender == owner, "You are not the owner"); _; } modifier onlyEntryPoint() { require( msg.sender == entryPoint, "Only EntryPoint can call this function" ); _; } // Function to validate a user-defined operation function validateOp( UserOperation calldata op, uint256 requiredPayment ) public returns (uint256) { // Send requiredPayment to EntryPoint if (requiredPayment != 0) { payable(entryPoint).transfer(requiredPayment); } // Check nonce require(op.nonce == nonce++, "Invalid nonce"); // Check signature if ( owner != getHash(op).toEthSignedMessageHash().recover( // op.signature[32:] op.signature ) ) { return SIG_VALIDATION_FAILED; } else { // return uint256(bytes32(op.signature[0:32])); return VALIDATION_SUCCESS; } } function getHash( UserOperation memory userOp ) public view returns (bytes32) { return keccak256( abi.encode( bytes32(block.chainid), userOp.sender, userOp.nonce, keccak256(userOp.initCode), keccak256(userOp.callData), userOp.callGasLimit, userOp.verificationGasLimit, userOp.preVerificationGas, userOp.maxFeePerGas, userOp.maxPriorityFeePerGas, keccak256(userOp.paymasterAndData), entryPoint // uint256(bytes32(userOp.signature[0:32])) ) ); } }You may also like | How to Create an ERC 721 NFT TokenA recent breakthrough: EIP-4337Since the account abstraction effort moved to a different strategy, which was unveiled in EIP-4337 in late 2021, both EIP-2938 and EIP-3074 are presently dormant. Building on the idea of a smart contract wallet is the goal of the new strategy.However, remember that we already mentioned that the lack of proper infrastructure makes smart contract wallets challenging to use? Nevertheless, EIP-4337 seeks to address that without altering the L1 protocol in the process.The proposal introduces a higher-level mempool that operates with a new object called UserOperations. Instead of traditional transactions, users will send UserOperations to this mempool. Validators then select these UserOperations, bundle them into a transaction, and submit them to a specialized smart contract called the EntryPoint contract. This contract manages transaction execution and validator rewards.The method outlined in EIP-4337 simplifies the process for developers to create custom smart contract wallets.Also, Know | Create a Simple Dividend ERC20 tokenConclusion of Account Abstraction Using ERC 4337:Account abstraction and ERC 4337 are two progressive approaches to Ethereum's development. This strategy is well-positioned to promote the wider use of blockchain technology and decentralised apps by giving priority to user experience, flexibility, and security, so making them more accessible and useful for regular users. The ideas and applications resulting from ERC 4337 will probably influence the direction of decentralised finance in the future and beyond as the ecosystem develops.

How to Build a Solana Sniper Bot How to Build a Solana Sniper Bot (Complete Guide with Code)Introduction to Solana Sniper BotsSolana is widely used for building decentralized applications due to its high transaction throughput, low fees, and fast finality. These features make it a suitable platform for real-time, automation-driven tools like Solana sniper bots, crypto sniper bots, and Solana dex bots.A Solana sniper bot is designed to monitor the blockchain and automatically execute token purchases the moment liquidity is added to a decentralized exchange (DEX). This is especially valuable during new token launches or other time-sensitive events, where timing can significantly impact outcomes.This guide provides a step-by-step walkthrough for building a Solana token sniping tool, with a focus on Raydium's CLMM (Concentrated Liquidity Market Maker) pools. It covers key setup steps, core logic, and best practices for handling transactions efficiently and securely.Understanding the BasicsWhat is a sniper bot on Solana?A sniper bot on Solana is a tool that automatically buys tokens as soon as they become available on a decentralized exchange (DEX), such as Raydium, PumpFun, Jupiter, or Orca.To build a robust sniper bot, you need to understand Solana's ecosystem, including its RPC (Remote Procedure Call) API, smart contracts (also known as programs), and key technical components such as transactions and signatures.Key Variants of Solana trading bots.Solana sniper bot code: Custom-built scripts that developers can run using Node.js and Solana Web3 libraries.Pumpfun sniper bot: Specifically designed to snipe tokens the moment they go live on Pumpfun.Raydium sniper bot: Targets liquidity events on Raydium's AMM or CLMM pools.Solana liquidity sniper: Monitors all liquidity events across the chain, not tied to a specific platform.Solana memecoin bot: Optimized for fast-entry trades on low-cap meme tokens.Solana trading bot: Broader than sniping, it handles full buy/sell logic, often including stop-loss and take-profit setups.Why Use Sniper Bots on SolanaIf you've ever tried to manually buy a newly launched token on Solana, you know how fast things move by the time you've clicked "confirm", the price may have already pumped or the liquidity is gone. Sniper bots solve that.They monitor the blockchain in real time and execute a trade the instant liquidity is added to a token. No hesitation. No manual steps. This gives you a massive edge in early-stage opportunities like token launches, meme coin listings, or NFT-associated tokens.Solana is especially suited for sniper bots because of its high throughput, sub-second finality, and near-zero transaction fees. You can scan logs, catch pool creation events, and trigger swaps within milliseconds without breaking the bank.Whether you're a solo trader, bot developer, or automating a crypto strategy, sniper bots give you precision timing in a market where seconds mean everything.Common Use CasesToken LaunchesSay a new meme coin drops on PumpFun. Within seconds of liquidity being added, prices can jump 2x or more. A sniper bot lets you detect the pool creation and buy before the masses.Early-Stage SpeculationSome traders monitor wallets of known devs or influencers. If a known wallet creates a pool, the bot buys immediately, before the token appears on aggregators like Birdeye or Dexscreener.Community Alpha PlaysYou're in a private alpha group. Someone posts a contract address. Your bot is hooked to Telegram or Discord and instantly buys based on that input.Low Liquidity MonitoringSometimes devs quietly add small liquidity to test their token. A bot can watch for this pattern like pools created with just 0.5 SOL and get in before announcements go live.Re-entry on RelaunchesIf a token rug pulls and relaunches, some bots monitor the same dev wallet or reuse of token metadata. They auto-buy the "second chance" version before hype catches upRisks & Legal ConsiderationsSniper bots give you speed, but they come with serious technical and legal risks.Rug Pulls & HoneypotsMany tokens launched on Solana DEXs are scams. Some prevent selling after buying (honeypots). Others drain liquidity right after launch. Without proper filters, your bot becomes easy prey.False PositivesBots can misfire on low-liquidity or bait pools. If your logic isn't strict,checking metadata, LP amount, token supply - you'll waste funds or get stuck in illiquid tokens.Front-RunningCompeting bots are monitoring the same logs. Your transaction might get front-run or stuck in a failed block. You need good RPCs, retries, and priority fee strategies.Wallet Drain RisksStoring private keys in.env files on a VPS without protection? That's asking for trouble. A single server compromise can drain your wallet.Legal Grey AreasDepending on your country, automated trading, especially around token launches might fall into regulatory gray zones. Some jurisdictions treat this as front-running or market manipulation.Treat your sniper bot as a serious software considering all the legal aspects.PrerequisitesBefore starting, make sure you have the following in place:Development Environment: Install Node.js, npm, and the Solana CLI.Solana Wallet: Create a wallet using Phantom, Sollet, or any compatible wallet.RPC Endpoint: Get access to a Solana RPC endpoint to communicate with the blockchain.Basic Knowledge of JavaScript: The bot will be written in JavaScript, so some familiarity is needed.You may also like |How to Build a Grid Trading Bot | A Step-by-Step GuideStep 1: Setting Up the ProjectStart by creating a new Node.js project:mkdir solana-sniper-bot cd solana-sniper-bot npm init -yThen, install the necessary packages:npm i @raydium-io/raydium-sdk-v2 @solana/web3.js axios bn.js bs58Step 2: Setting Up Environment VariablesCreate a.env file in the project root to store sensitive information, such as your private key and RPC endpoint:PRIVATE_KEY=your_private_key_here SOL_RPC=https://api.mainnet-beta.solana.comStep 3: Create the CLMM Pool ListenerThis script listens to the Raydium CLMM program logs and detects when a new pool is created.// index.js import { Raydium, PoolUtils, TxVersion, } from '@raydium-io/raydium-sdk-v2' import { Connection, PublicKey, Keypair, } from '@solana/web3.js' import bs58 from 'bs58' import BN from 'bn.js' import 'dotenv/config' // === CONFIG === const RPC_URL = process.env.SOL_RPC const secretKey = bs58.decode(process.env.PRIVATE_KEY) const wallet = Keypair.fromSecretKey(secretKey) const connection = new Connection(RPC_URL, { commitment: 'confirmed' }) const SOL_MINT = 'So11111111111111111111111111111111111111112' const CLMM_PROGRAM_ID = 'CAMMCzo5YL8w4VFF8KVHrK22GGUsp5VTaW7grrKgrWqK' const BUY_AMOUNT_SOL = 0.01 const SLIPPAGE = 0.03Also, Read |Understanding the Impact of AI Crypto Trading BotsStep 4: Create the Buy Function (Auto Swap)async function buyWithClmm(poolId, tokenMint) { const raydium = await Raydium.load({ connection, owner: wallet }) const Pooldata = await raydium.clmm.getPoolInfoFromRpc(poolId) const poolInfo = Pooldata.poolInfo const poolKeys = Pooldata.poolKeys const clmmPoolInfo = Pooldata.computePoolInfo const tickCache = Pooldata.tickData const baseIn = tokenMint === poolInfo.mintA.address const inputAmount = new BN(Math.floor(BUY_AMOUNT_SOL * 1e9)) const { minAmountOut, remainingAccounts } = PoolUtils.computeAmountOutFormat({ poolInfo: clmmPoolInfo, tickArrayCache: tickCache[poolId], amountIn: inputAmount, tokenOut: poolInfo[baseIn ?

Modify your.env file to use the devnet RPC endpoint:SOL_RPC=https://api.devnet.solana.comAlso, Explore |How To Create My Scalping Bot Using Node.jsStep 7: Deployment and SecurityOnce the bot is ready, deploy it to a secure server:Use a VPS to ensure the bot runs continuously with minimal downtime.Secure Your Private Key: Always use environment variables or a secure vault service to store sensitive information.Real-World OptimizationsOnce your sniper bot is functional, it's not ready yet. Real-world trading on Solana is messy. You're racing against other bots, navigating scam tokens, and reacting to volatile conditions. This section covers the essential optimizations to make your bot safer, smarter, and more reliable.Filtering Bad Tokens (Pre-Buy Checks)Minimum Liquidity ThresholdAvoid pools with low initial liquidity. Rugs often launch with under 1 SOL to bait bots. Set a minimum liquidity requirement before proceeding with any buy logic.if (poolLiquidityInSol < 1) return;Token Metadata ValidationCheck that the token has a valid symbol, name, and decimal count. Tokens with missing or weird metadata are red flags.if (!tokenMeta.symbol || tokenMeta.symbol.length > 10) return;Token BlacklistMaintain a list of known scam tokens or deployers and skip them instantly.if (BLACKLIST.includes(targetMint)) return;Optional: Simulate Swap or Check RouteUsesimulateTransaction() to preview the swap or query a route via Jupiter. If it fails or no route exists, don't buy.Delay-Based Decision MakingIntroduce a short delay (e.g., 2–5 seconds) after pool creation. This gives time to detect sketchy behavior like immediate liquidity removal or fake metadata updates.Using Multiple RPCs (Failover Strategy)RPC List ConfigurationSet up a list of RPC endpoints (e.g., Helius, Triton, QuickNode). Load them from.env or config file.const RPCS = [RPC1, RPC2, RPC3];Retry and Fallback MechanismIf one RPC fails, retry with another. Rotate through the list to maintain uptime and reduce failure points.for (const rpc of RPCS) { try { const conn = new Connection(rpc); // test or send tx break; } catch (err) { continue; } }Logging and MonitoringEvent LoggingLog what matters: detected pools, attempted buys, successful swaps, token details.console.log(`[POOL] ${poolId} | Token: ${tokenMint}`);Error TrackingUsetry/catch around every major async operation and log failures with stack traces.console.error(`[ERROR] ${err.message}`);Optional IntegrationUse tools like:PM2 to auto-restart the bot on crashWinston for structured loggingCloud services like Logtail or Datadog for remote log collectionOptional: Sell Logic and Exit StrategyTake-Profit ThresholdSet a target percentage (e.g., 2x from entry) and auto-sell when the token reaches that price.if (currentPrice >= buyPrice * 2) { await sell(); }Stop-Loss SetupProtect your downside. If price drops below a defined floor, exit.if (currentPrice <= buyPrice * 0.7) { await sell(); }Time-Based ExitsIf the price doesn't move after a certain duration (e.g., 3 minutes), exit anyway to avoid being stuck.Future ExtensionsRe-entry after dipsMulti-wallet rotation for stealthDiscord/Telegram alert triggersToken sell simulation before actual sellThese optimizations turn your bot from a proof-of-concept into something stable and reliable in real conditions. You don't need them all on day one—but without them, you're flying blind.Troubleshooting & Common ErrorsBuilding a sniper bot is one part logic, one part infrastructure. Once you go live, unexpected failures are common. Here's what usually goes wrong—and how to fix it without guessing:Bot doesn't detect new poolsIf the bot isn't picking up events, double-check you're subscribed to the correct program ID (e.g. Raydium CLMM). Also verify you're using theconfirmed orfinalized commitment level—notprocessed, which can miss orphans.Transaction isn't sent or gets stuckThis typically means your RPC is rate-limited or too slow. Use a premium provider (Helius, Triton, QuickNode) and avoid free shared endpoints. Also, wrap yoursendTransaction logic with retry and timeout handling.Buy transaction fails or revertsMost often caused by too-tight slippage, incorrect token metadata, or race conditions where the pool state changes before execution. Validate slippage settings and simulate trades with mock inputs before going live.Private key or wallet errorsIf the script throws on wallet load, your key may be malformed or improperly encoded. Ensure it's base58 and single-line (no[] or extra JSON formatting). Load it usingbs58.decode() and test it with a small transfer.Bought tokens but can't sellThis is likely a honeypot. To avoid it, always validate:Token has a valid symbol and nameSufficient liquidity (avoid pools under 1 SOL)No known blacklist flags or scam patternsThe bot crashes randomlyUsetry/catch blocks around all async calls—especially in listeners. Log every error. Run the bot with a process manager like PM2 or Docker health checks so it auto-restarts on failures.Logs show “CreatePool” but no buy happensCheck if yourisProcessing flag is stuck or the transaction failed silently. Add more detailed logging per step, and track execution time for each transaction to find where it stalls.Official Solana & Raydium DocsSolana Developer Docs – Core concepts, transaction structure, RPC methods, and program architecture.Solana Cookbook – Developer-friendly guides for common Solana tasks.Raydium SDK v2 – Reference for CLMM pool interaction, swap logic, and liquidity provisioning.ConclusionBuilding a sniper bot on Solana requires a solid grasp of how the blockchain works, especially its transaction model, smart contract architecture (programs), and RPC interactions. This guide walked through each step: from setting up the environment, listening to liquidity events, executing token swaps, and handling real-time conditions.Before moving to mainnet, it's essential to thoroughly test your bot on devnet. This helps catch logic errors, slippage issues, or RPC failures without risking real assets. Always secure your wallet keys and credentials using proper secret management practices.With proper filtering, real-time logging, and infrastructure improvements, this bot can become a reliable component in automated crypto trading workflows. Whether you're experimenting, building trading tools, or exploring automation at scale, Solana provides the speed and flexibility needed to execute on-chain trades with minimal delay.
