Airdrop ERC-20

Airdrop ERC-20 tokens or the chain's native token (e.g. ether for Ethereum mainnet) to a list of recipients.

The AirdropERC20 contract is suitable to use when you want to transfer ERC20 tokens or native tokens to a list of recipient addresses, where these recipients are not expected to individually claim their airdrop; they just receive it in a transfer. When airdropping tokens with this contract, you specify:

  • The address of the ERC20 token being transferred. (For native tokens, the address used is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE)
  • The address from which the token will be transferred to a list of the recipients.
  • An array of objects containing recipient-address and token-amounts, for e.g.
[
  {
    recipient: "0x123...",
    amount: 1, // these amounts are in wei
  },
  {
    recipient: "0xabc...",
    amount: 10, // these amounts are in wei
  },
];

note: token-owner must approve their tokens to this airdrop contract, by calling approval related function on the ERC20 token contract.

Estimated gas costs for airdropping tokens: Cost of airdropping 1 ERC20 token: ~66,600 gas. Cost of airdropping each additional ERC20 token: ~32,526 gas.
