π Day 34 of 100DaysOfBlockchain: Deep Dive into Merkle Airdrops and Signature Verification π π Introduction to Merkle Airdrops and Signatures Today, I explored the exciting world of Merkle airdrops and digital signatures. A Merkle airdrop allows us to efficiently and securely distribute tokens, leveraging the cryptographic structure of Merkle trees to verify proofs. βοΈ Implementing the Base Airdrop Contract I wrote a base smart contract, MerkleAirdrop.sol, incorporating Merkle tree logic to check if an address is eligible for an airdrop. This contract includes mechanisms to prevent double-claiming and verify signatures. π Adding Signature Verification I integrated signature verification into the airdrop contract using standards like EIP-191 and EIP-712. This ensures that only the intended recipients can claim the tokens, adding an extra layer of security.
