ERC20 & ERC721/ERC1155 Payout Claim
A production-ready Web3 payout infrastructure for distributing ERC20 tokens and NFTs to thousands of users via a Merkle tree verified claim system.
The Challenge
Distributing tokens fairly and efficiently to thousands of users manually via loops is astronomically expensive in gas costs and fragile at scale.
Core Offerings
A production-grade payout claim system built around cryptographic Merkle proofs.
MerkleClaimer (ERC20)
Allows whitelisted addresses to claim tokens using a Merkle proof, avoiding on-chain storage bloat.
MultiTokenClaimer (NFTs)
Supports batch claims of specific token IDs from ERC721/ERC1155 collections.
Backend Tree Generation
A Node.js service constructing reliable Merkle trees from CSVs and exposing REST APIs for frontend proofs.
Frontend Interface
Next.js dApp integrating wagmi hooks for seamless WalletConnect, MetaMask, and Coinbase Wallet claims.
Technical Architecture
The Impact
"Successfully facilitated multi-million dollar token distributions with optimized gas overhead and bulletproof security guards against reentrancy and griefing attacks."
