Benefits of Token Multisender
One transaction, not hundreds
the batch pays Ethereum's per-transaction cost once instead of once per recipient
Real gas savings
bundling ERC-20 transfers is what makes a large airdrop affordable on Ethereum
Audited by Halborn
non-custodial, tokens go straight from your wallet to each recipient
Typos caught before you pay
every address is validated in the browser, not on-chain
CSV or paste
upload a holder export or type the list in, with a custom amount per row
Proven at scale
over 270,000 wallets paid through Smithii's multisenders

Sending 500 ERC-20 transfers by hand means paying Ethereum's 21,000 gas floor 500 times over. The Multisender batches the recipients into one call per batch, so you pay that floor once and only the per-recipient token write inside. On mainnet that is often the difference between an airdrop you can afford and one you cannot.
Almost always, and by a wide margin on mainnet. Each standalone transfer pays the base gas cost of a transaction before it moves a single token; batching pays that once per batch. The larger the list, the larger the gap, which is why nobody airdrops on Ethereum one transaction at a time.
It is non-custodial: the contract moves tokens out of your wallet to the addresses you listed, and it can never touch anything else you hold. The contract is audited by Halborn and every batch settles publicly on Etherscan, so the distribution is verifiable line by line after the fact.
Two columns (address and amount), one recipient per row, pasted in or uploaded as CSV. No header row is required. Every address is validated before anything is signed, so a typo is caught in the browser rather than paid for in gas.
A small fee in ETH per recipient, plus the network gas for each batch. The form totals both before you sign, so you see the whole cost of the airdrop rather than discovering it batch by batch.
A ERC-20 token cannot be moved by a contract unless you allow it, so every airdrop is approve-then-send. The approval names the multisender and an allowance; the batches spend against it. Check the amount you grant. An unlimited allowance stays live afterwards, and revoking it is a separate transaction on Etherscan.
From a snapshot. The Snapshot tool exports every holder of a token or NFT collection with their balance as a CSV, which drops straight into this form. Adjust the amounts and send.
Invalid addresses are flagged and dropped before submission, so no gas is spent on them. If a batch fails on-chain the tokens stay in your wallet; the tool reports which batches settled and which did not, and you can resend the remainder.
Why batching beats sending one by one
Every Ethereum transaction pays a 21,000 gas floor before it does anything, and an ERC-20 transfer adds two balance writes on top. Send to 500 wallets individually and you pay that floor 500 times. A multisender pays it once per batch and only the per-recipient write inside, which on mainnet is the difference between an airdrop that happens and one that does not.
Where the recipient list usually comes from
Most airdrops go to a list somebody already holds: a snapshot of token holders, an NFT collection, a whitelist exported from a form. Any of those can be pasted or uploaded as a CSV with an address and an amount per row. If you do not have the list yet, take a holder snapshot first and feed its export straight into this form.
What the approval actually authorises
An ERC-20 cannot be moved by a contract unless you allow it first, so the flow is always approve-then-send. The approval names the multisender contract and an allowance; the batches spend against it. It is worth checking the amount you grant. An unlimited allowance stays live after the airdrop, and revoking it is a separate transaction on Etherscan.
