Batches on Blast pay L2 fees, so reaching a few thousand holders stays proportionate to the distribution rather than dwarfing it. Approve once, upload the list, and every batch is signed from your own wallet.
The tokens you send leave your wallet, so whatever they were accruing accrues for the recipient instead. The ETH you spend on gas and fees leaves too. Nothing else about your position changes.
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 BlastScan, 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 BlastScan.
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.
Airdropping on Blast
Batches on Blast pay L2 fees, so the cost of reaching a few thousand holders stays proportionate to the distribution rather than dwarfing it. The mechanics are the standard ones: approve once, upload the list, and each batch signs from your own wallet.
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 BlastScan.
