Airdrop ERC20 Claimable

thirdweb's AirdropERC20Claimable contract

The AirdropERC20Claimable contract is suitable to use when you want to airdrop ERC20 tokens to a list of recipient addresses, where these recipients are expected to individually claim their own airdrop.

When deploying this contract, you specify:

• The address of the ERC20 token being airdropped.
• The total token amount to airdrop.
• The address of the owner of tokens from whom tokens will be transferred out in the airdrop.
• The UNIX timestamp after which the airdrop period will expire.
• A maximum claimable amount per wallet (claiming the airdrop).
• An optional merkle root allowlist for recipients permitted to claim the airdrop.

On claiming an airdrop, a recipient specifies:

• The address to transfer the claimed airdrop to.
• The total quantity to claim.
• The proof of inclusion in the merkle root allowlist, if it exists.
