What an Arc airdrop costs in USDC
An Arc airdrop through the multisender has up to 4 costs.
Tokenry fee: 0.1 USDC for each recipient whose payout goes through, paid to Tokenry.
Gas: paid to the network for each transaction. Your wallet shows it before you confirm.
Approval gas: for a token send, the gas of an approval transaction when the token needs one.
The payouts: the USDC or tokens you send, which go to the recipients.
For 100 recipients, the Tokenry fee is 10 USDC in 1 transaction. For 1,000 recipients, it is 100 USDC, which the review splits into 3 transactions of 400, 400 and 200, each with its own gas.
For a USDC send, the amounts, the Tokenry fee and gas all come from one USDC balance. The review checks that balance for you. You need no ETH or other coin for these transactions (how gas works on Arc).
