P256 signature verification solidity contract

Reference ERC7518 security token

This project implements an Ethereum-based token airdrop using Merkle Trees and EIP-712 signatures for secure and gas-efficient claims. The contract ensures that only eligible users (based on a pre-generated Merkle Root) can claim tokens, and it verifies their identity using cryptographic signatures.

MerkelAirdrop is a Solidity smart contract deployed on the Sepolia testnet that facilitates secure and verifiable token airdrops using Merkle proofs and EIP-712 signatures. This is updated version of previous MerkleAirdrop as it does not expect v,r,s values it expects user to directly pass signature.

Signing messages off-chain and having a contract that requires that signature before executing a function is a useful technique.

This project enables claiming of airdrops. Claimers can pay their gas fees or have someone else do so

A token claim system with signature verification and whitelisting functionality.

A cutting-edge token distribution system that combines Merkle tree verification with EIP-712 signatures for maximum security and gas efficiency. Built with Foundry and OpenZeppelin, this protocol implements double-layer cryptographic validation, pre-image attack protection, and comprehensive testing. Perfect for secure, scalable token airdrops.
