Avalanche Multisender: Send AVAX or ERC-20 Tokens to a C-Chain Address List

AVAX needed for the Tokenry fee, gas and approvals

The Avalanche airdrop tool fits a token distribution such as a community airdrop, presale payouts or contributor rewards. To airdrop tokens on Avalanche with the multisender, you pay up to 4 costs, and only the Tokenry fee goes to Tokenry. No token yet? See how to create a token on Avalanche.

Tokenry fee: 0.02 AVAX per recipient, only for payouts delivered. It goes to Tokenry.

Gas: paid in AVAX by your wallet for each send transaction, shown before you confirm. It is burned by the network (C-Chain fees).

Token approval: none for AVAX. A token may need one or two approval transactions, each with its own gas, burned by the network.

The amounts you send: AVAX or the token, as set in your list. They go to your recipients.

Example: 1,000 recipients mean a 20 AVAX Tokenry fee and 3 send transactions (400 + 400 + 200), each with its own gas. 250 recipients mean 5 AVAX and 1 transaction. Your total is the Tokenry fee, plus gas, plus the amounts you send, plus approval gas when a token needs it.

Keep a little more AVAX in your wallet than the estimated gas.

Token approvals on Avalanche cover only your list total

You need no approval to send AVAX with the multisender. From a regular wallet, many tokens need only a permit signature, not an approval transaction. That signature costs no gas and covers every transaction of the send. Native USDC on Avalanche is one of these tokens.

Other tokens need one approval transaction for the exact total of your list, never an unlimited amount. A smart-contract wallet gets this approval for every token. If your existing allowance already covers the total, no approval is needed. If an older, smaller approval exists, it is set to 0 first, so your wallet shows 2 approval transactions.

You need no special authority over the token contract: any wallet can send the tokens it holds. A token's transfer tax applies as on a normal send from your wallet. The review shows any recipient who would get less than listed, and how much.

What happens when an Avalanche payout or transaction fails

A refused payout: if the token or the recipient refuses a payout on the Avalanche C-Chain, the multisender skips it. Its amount and its Tokenry fee come back to you in the same transaction, and the other payouts still go through.

A failed transaction: if a whole transaction fails, nothing in it is sent. The gas for that transaction is still spent. Transactions confirmed before it are not affected.

After a partial send, "Send the remaining" pays only the recipients not yet paid in that send.

When a send had more than one transaction or a skipped payout, you can download the delivered, skipped and not-sent recipients as CSV files. Every transaction has a Snowtrace link, so you can check each one. For the other steps around a launch, see the Avalanche token tools.
