ByteNFT is an upgradable ERC-721 smart contract deployed on the Base L2 blockchain, allowing users to mint NFTs using fiat currency. Integrated with Transak, the platform facilitates seamless fiat-to-crypto conversion and NFT distribution through a secure and scalable contract architecture. The system automates minting, wallet verification, and fund management for enhanced user experience and transparency.

Develop and deploy an upgradable (UUPS) ERC-721 contract using Solidity and Hardhat, integrated with Transak for fiat on-ramping. Implement minting, burning, admin controls, treasury management, and secure USDC handling. Ensure smart contract extensibility, automated testing on Base Sepolia, and CI/CD-ready deployment with error-handling and access control.

We delivered a modular, upgradeable NFT minting platform with full Transak integration, enabling fiat payments, automated KYC, and NFT delivery to end users. Our contract ensures payment validation, USDC treasury security, and upgradability for future features like royalties or metadata reveals. The system is built using best-in-class Solidity practices with CI/CD pipelines and robust access/mint controls.
