DagDrop

DeFiMerkle airdrop

Token airdrops with Merkle proofs. Create one, recipients claim in one tx.

A permissionless airdrop factory. Anyone can deposit an ERC-20 and a Merkle root, set an expiry, and let recipients claim their exact share by providing their proof. Creator reclaims unclaimed tokens after expiry.

Contracts

How to use

1

Off-chain: build your recipients list, compute the Merkle root (leaf = keccak256(addr, amount)).

2

Approve DagDrop for the total token amount, then call create(token, merkleRoot, totalAmount, expiry) with 10 BDAG creation fee.

3

Recipients call claim(dropId, amount, proof) to pull their allocation — one transaction, no whitelist management.

4

After the expiry, creator calls reclaim(dropId) to sweep anything unclaimed.

Cost

10 BDAG flat fee per airdrop created. No fee for claimants. Creators set expiry and reclaim unclaimed tokens.
