How many wallets can one transaction or signature carry?
There is no cap on the list. The 8 EVM chains take up to 400 recipients per transaction, and each Solana signature covers about 150 to 320, depending on the token and on whether wallets need a new token account. So 2,000 wallets means 5 EVM transactions or about 7 to 14 Solana signatures. The 400 keeps a typical send under the strictest per-transaction gas limit among these chains.
What can the multisender do with my token approval?
It can only move the total in your list. Each transaction pulls only its own recipients' amounts and pays them out in that same transaction. You may need two approvals if a smaller allowance from an earlier send has to be reset to zero, and none if your allowance already covers the send. The native coin and Solana skip approval.
What if one part of my airdrop fails?
Only the failed part needs to go out again. Each EVM transaction pays all of its recipients or none of them, and a failed one charges no service fee, though its gas is spent. On Solana, a transaction that did not land expires and charges nothing. Resend those addresses from the same screen, or download the not-sent list.
Can each wallet get a different amount, and what should the list look like?
Each line carries its own amount, written after the address, one recipient per line. Upload the list as a CSV file or a .txt file. A header row, extra columns such as names, and any column order are fine; amounts use a dot for decimals. Or pick Equal split to divide one total, or Same amount each, and list addresses only. A repeated address shows "Duplicate of line N" and is left out, so only its first line is paid.
Can I try the multisender without paying?
Test with a small send to two or three of your own wallets first, at the normal fee. The tool runs on mainnet only, with no testnet and no free tier. Reading the full review costs no service or transaction fees, and you pay only when you sign. The review needs a connected wallet that holds enough of the token, and on Solana enough SOL for the costs.
Do recipients need to claim anything?
Recipients do nothing. The tokens arrive when the send confirms. On Solana, the send opens a token account at your cost for any address that has none for your token yet. SOL sent to an empty wallet is raised to Solana's rent minimum, so the transfer goes through.
Can I airdrop any token, even one with a transfer tax?
Most tokens and native coins work. On EVM, a transfer tax or holding limit can fail the send or pay less unless the chain's multisender contract is exempt. For a Tokenry token you still own, exempt that contract under Token Manager's Fee exemptions and Exempt from the limit. Each wallet must end within the holding limit, or its transaction fails. On Solana, Token-2022 transfer fees come out of what arrives.
Which wallets can I send from?
On EVM, use a browser extension wallet such as MetaMask or Coinbase Wallet, or a mobile wallet through WalletConnect. On Solana, use Phantom, Solflare or Coinbase Wallet, or scan a WalletConnect QR code with a phone wallet. Approve each Solana signature within about 30 seconds of the wallet opening; a late approval sends and charges nothing, and you sign again.
