Multisender — devnet test
Send SOL — or one SPL / Token-2022 token — to many wallets in a single batch: team allocations, supporter rewards, presale distribution. Paste a list or import a CSV file, review every line, then sign a short sequence of transactions. This test version runs only on Solana devnet.
1. Connect your wallet
Uses your browser wallet extension (Phantom-compatible, window.solana). Switch the wallet itself to devnet first if it lets you choose a network. We never see or handle your private key — signing happens inside your wallet.
2. What are you sending?
3. Recipients
One recipient per line: address,amount — a comma or spaces between the two fields both work. You can paste directly or import a .csv / .txt file (the file is read only in your browser; importing replaces the text below). Every line is validated before anything is built: bad addresses, bad or non-positive amounts, amounts with more decimal places than the asset allows, and duplicate addresses are each flagged with their line number. Flagged lines are excluded from the batch — nothing invalid is ever sent to silently. If the same address appears twice, the second line is flagged as a duplicate and excluded; merge the amounts into one line yourself if that is what you intended.
4. Full summary — shown before any signing
Our service fee: 0.0008 SOL per recipient, with a minimum total fee of 0.01 SOL per batch, collected as a single transfer inside the first transaction of the batch — there is no separate payment step. Rent for new recipient token accounts is an estimate (~0.00148844 SOL each, the standard token-account rent at Solana's current rent rate); the exact lamports are set by the network when the account is created. Network fees are paid to the network, not to us.

5. Review, confirm, sign
Once a transaction in this batch confirms, the SOL or tokens in it have left your wallet for good. There is no recall, no refund and no way for anyone — including us — to reverse a confirmed send. Check every address and amount in the summary download before you sign.
Transactions are sent one at a time, in order. If one fails, the batch stops — nothing is retried or re-sent automatically, and recipients in later transactions are simply not sent to. Every confirmed signature is recorded in this browser under the batch ID: if you reload the page mid-batch, a warning above will remind you which batch was already partially sent, so you do not send to the same wallets twice by accident.
Good to know
A batch is split into several transactions because one Solana transaction has a fixed size limit — the summary shows exactly how many. Sending tokens to a wallet that has never held that token requires a token account for that wallet + mint; creating it costs rent, which is why token batches to fresh wallets cost more SOL than the amounts alone suggest.
