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 The Solana blockchain, known for its high throughput and low transaction costs, has become a prominent platform for blockchain app development. Among the various tools and bots built on Solana, the "sniper bot" stands out for its ability to automatically purchase tokens as soon as they become available. This is especially useful during token launches or other time-sensitive events.In this guide, we'll walk you through building a Solana sniper bot, with a particular focus on integrating it with Raydium DEX. You'll learn about the key components, technologies, and strategies involved in developing an efficient sniper bot.Understanding the BasicsA 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.Before starting, ensure you have the following prerequisites:Development Environment: Set up Node.js, npm, and the Solana CLI.Solana Wallet: Create a wallet (using Phantom or Sollet, for instance).RPC Endpoint: Obtain access to a Solana RPC endpoint to interact with the blockchain.Basic Knowledge of JavaScript: We'll use JavaScript to write the bot.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 -y Then, install the necessary packages:npm install @solana/web3.js axios dotenv Step 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.com RAYDIUM_FEE_ACCOUNT=your_fee_account_here Step 3: Creating the Listener for New PoolsCreate a listener that detects when new pools are added on Raydium:const { Connection, PublicKey } = require("@solana/web3.js"); const MAX_SIZE = 10000; const seenTransactions = new Set(); class RaydiumPoolListener { constructor() { this.connection = new Connection(process.env.SOL_RPC, { commitment: "confirmed" }); this.listenToNewPools(); } listenToNewPools() { this.connection.onLogs(new PublicKey(process.env.RAYDIUM_FEE_ACCOUNT), async (txLogs) => { if (seenTransactions.has(txLogs.signature)) return; if (seenTransactions.size >= MAX_SIZE) { [...seenTransactions].slice(0, 50).forEach((tx) => seenTransactions.delete(tx)); } seenTransactions.add(txLogs.signature); // Trigger swap function with the necessary parameters swap(txLogs.tokenAmount, txLogs.tokenAddress, txLogs.poolId); console.log("New pool detected, initiating swap..."); }); console.log("Listening for new liquidity pools..."); } } module.exports = new RaydiumPoolListener(); Also, Read | Understanding the Impact of AI Crypto Trading BotsStep 4: Integrating the Raydium SDKUse the Raydium SDK to execute swaps once liquidity is added to a pool:const { initSdk } = require('@raydium-io/raydium-sdk-v2'); const BN = require('bn.js'); const Decimal = require('decimal.js'); async function swap(amountOfSol, solAddress, poolId) { const raydium = await initSdk(); const poolData = await raydium.api.fetchPoolById({ ids: [poolId] }); const poolInfo = poolData[0]; if (!poolInfo) throw new Error("Pool not found"); const rpcData = await raydium.liquidity.getRpcPoolInfo(poolId); const [baseReserve, quoteReserve] = [rpcData.baseReserve, rpcData.quoteReserve]; const out = raydium.liquidity.computeAmountOut({ poolInfo, amountIn: new BN(amountOfSol), mintIn: solAddress, slippage: 0.01, }); const { execute } = await raydium.liquidity.swap({ poolInfo, amountIn: new BN(amountOfSol), amountOut: out.minAmountOut, fixedSide: 'in', inputMint: solAddress, }); const { txId } = await execute({ sendAndConfirm: true }); console.log(`Swap successful! Transaction ID: https://explorer.solana.com/tx/${txId}`); } For further reference, explore the Raydium SDK V2 Demo.Step 5: Testing the BotBefore deploying your bot on the mainnet, it's crucial to test it thoroughly on Solana's devnet.
