Bulksender Features
A bulksender submits many ERC-20 transfers in one airdrop transaction instead of asking for a separate wallet confirmation per recipient. Paste or upload up to 1,000 EVM recipients, preview the list and sign. If the allowance is insufficient, approve the exact required amount first. Divide larger distributions into separate runs.
One EVM airdrop transaction
After an approval when required, submit up to 1,000 recipients in one transaction. Larger lists must be divided into separate runs.
Gas is the whole point
A plain transfer costs the full 21,000 gas floor plus the token write, every time. Batching amortises the base cost across the whole list, which is where the saving comes from. And why the cheapest network matters more than the tool fee.
Non-custodial
The contract moves tokens from your wallet to the recipients within the transaction you signed. Nothing is ever deposited with Smithii.

A fee per recipient wallet, charged by the contract in the network's own currency, plus gas. The table below is the fee on every network the tool supports. The gas is what actually varies, and by a lot.

Nothing, in practice. Both names describe a tool that moves one token to many addresses through a single reviewed workflow. "Bulksender" is common in the Ethereum ecosystem and "multisender" is common on Solana.
If the existing allowance is insufficient, yes. ERC-20 requires the holder to authorise the sender contract before it can move the required token amount. The approval costs network gas but no separate Smithii fee.
On EVM networks, up to 1,000 recipients per airdrop transaction. Divide a larger distribution into separate runs; the tool does not split it automatically.
Yes. Upload a CSV with an address and an amount per row, or paste the pairs directly. Sending the same amount to everyone is also supported.
A reverted EVM transaction pays no recipients. Correct the reported problem and submit the reviewed list again.
Whichever has the lowest gas at the time you send, which is almost never Ethereum L1. Every recipient pays L1 gas there. The fee table above shows the tool fee; check the current gas price for the real total.
Why one contract call is simpler than sending one by one
Sending manually requires a separate wallet action for each recipient. On EVM networks the bulksender submits the reviewed list through one contract transaction for up to 1,000 recipients, reducing repeated prompts and making the complete run easier to verify.
What the approval actually authorises
ERC-20 has no way for a contract to move your tokens unless you authorise it first. If the existing allowance is insufficient, the wallet approves the exact amount required; the airdrop transaction then spends against that allowance.
Where the recipient list usually comes from
Most bulk sends 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 CSV. If you do not have the list yet, take a holder snapshot first and feed its export straight into this form.
