Unichain Multisender: Airdrop Tokens for 0.0001 ETH per Recipient

Senders on Unichain (chain ID 130) can airdrop ETH or a Unichain ERC20 token from their own wallet to a list of addresses with Tokenry's Unichain multisender. A send takes one transaction for every 400 wallets, plus one for any left over. Tokenry's service fee is 0.0001 ETH for each recipient; network fees are paid separately in ETH.

How it works

The process to send tokens to multiple addresses on Unichain

  1. 1

    Connect on Unichain mainnet

    Your ETH and tokens must be in the wallet you connect. If it is on another network, the page requests a switch to Unichain mainnet, chain ID 130.

  2. 2

    Find the token in the menu, or paste its contract address

    The menu lists ETH and the tokens on Unichain your wallet holds; pick one per list.

  3. 3

    Set amounts per address or for the whole list

    Pick Same amount each, Equal split or Custom per address, then enter wallet addresses; a header row is fine. A repeated address shows as Duplicate; only its first line counts.

  4. 4

    Compare the review with your recipient list

    Press Review airdrop and check the total it shows against your own records. Nothing is signed at this stage, and going back keeps your entries.

  5. 5

    Press Confirm and send

    Your wallet asks for any token approval first, then one confirmation per transaction. Each multisend transaction gets its own Uniscan link on the progress screen.

FAQ

Frequently Asked Questions

Something not covered here? Contact support.

Is Tokenry's multisender on Unichain the same contract as on other chains?

It is the same type of smart contract, TokenMultiSender, deployed at a different address on each EVM chain. On Unichain (chain ID 130), it is 0x50D4d7C4e05c3C756C4BfB2023f4a13CE5cbfF20. Uniscan shows its source code verified as an Exact Match, Blockscout shows it verified, and neither marks it as a proxy.

How fast does a Unichain multisend confirm with 1-second blocks?

Unichain adds a block about once a second, and per Uniswap's docs, Flashblocks add 200 ms preconfirmations, an early sign of inclusion. The progress screen waits for the receipt, the record that the transaction is in a block, and checks every 2 seconds. On a long list, how quickly you answer each wallet prompt decides how long the send takes.

Can I pay recipients in UNI on Unichain?

Yes, if the UNI is on Unichain, where it is a separate ERC20 contract, 0x8f187aA05619a017077f5308904739877ce9eA21. Its approval is for exactly the list total, skipped when your current allowance is enough, with a zero approval first when some allowance remains or cannot be read. To distribute USDC, use Circle's native contract, 0x078D782b760474a361dDA0AF3839290b0EF57AD6.

The details

More about the Unichain Multisender

01

The cost of a Unichain multisend

Every recipient on a Unichain token airdrop adds a flat service fee of 0.0001 ETH. Network fees are separate and also paid in ETH. They cover gas for each transaction plus the L1 data fee, the cost of publishing the transaction's data on Ethereum. Unichain runs on the OP Stack, the same base as OP Mainnet. The Optimism multisender page explains how the L1 data fee grows with each wallet.

A 1,500-wallet bulk send costs 0.15 ETH in service fees across 4 transactions, which carry 400, 400, 400 and 300 wallets. Each of the 4 adds its own gas and L1 data fee, and so does any approval on a token list. All of this ETH must already be on Unichain when you press Confirm and send. For gas per wallet against one-by-one sends, see the Ethereum multisender.

02

Checking a Unichain send on Uniscan

Uniscan is Unichain's block explorer. On a multisend's transaction page, ETH amounts appear under internal transactions. An ERC20 list shows one token transfer of the list total from your wallet into the multisender contract, then one out to each recipient.

The contract is 0x50D4d7C4e05c3C756C4BfB2023f4a13CE5cbfF20, with its source code on the Contract tab. When a list is split, the progress screen also offers CSV files of the recipients delivered and, if any, of those not sent.

03

Each Unichain transaction succeeds or reverts on its own

Tokenry's airdrop tool splits a long list across as many transactions as it needs and stops each one at 400 wallets. Unichain accepts at most 16,777,216 gas per transaction, and 400 transfers of ETH, USDC or UNI fit under that limit. The transactions go out in list order, so the first covers recipients 1 to 400 and the next starts at 401.

A Unichain transaction that reverts, meaning it fails on-chain, is undone in full along with Tokenry's fee. Only its network fees are spent. Any earlier transaction that confirmed keeps its transfers. The progress screen then offers a resend of the unpaid wallets only, and each resent transaction needs your confirmation again.

For a token that charges a transfer tax, exempt the multisender contract from the tax before sending, or the distribution can revert. To airdrop tokens on other EVM chains or Solana, start at the multisender hub.
