MASTRsender

MASTRsender sends SOL or any SPL token to hundreds of wallets in one go, straight from your phone. Import a list, check the dry run, sign a handful of transactions, done. BUILT FOR THE PART THAT USUALLY GOES WRONG Most multisenders can send. The hard part is what happens when a run breaks halfway: a wallet that loses the connection, a phone that goes to sleep, a network that drops. MASTRsender is built around exactly that moment. - Dry run before anything is signed. Every packet, the total, the rent for new token accounts, the network fee and the service fee are on screen, and every transaction can be simulated against the chain before a single lamport moves. - Resume without double payouts. Every packet is written to disk with its signature and block height. When you come back, the app asks the chain what actually happened before it rebuilds anything. A transaction that might already be on chain is never sent twice. - Exportable log. Every run produces a CSV and a printable PDF receipt with recipients, names, amounts, packet status and signatures, plus one tap to any transaction on Solscan, SolanaFM or Solana Explorer, whichever you prefer. IMPORT ANYTHING, EDIT EVERYTHING CSV, TSV, TXT or Excel (.xlsx). The app finds the address column by content, not by header, and a name column next to it fills your address book. The same file loads into a campaign, and without the amount column into your contacts. Every row is editable in place. Give everyone the same amount, split a total equally or by weights, sort, remove errors and duplicates, add recipients from your contacts, undo any step, export the finished list as CSV. AN ADDRESS BOOK, ON YOUR DEVICE Save wallets with a name, notes, tags, a colour and a photo. Runs, lists and reports then show "Anna, community mod" instead of "9xQe…VFin", and every contact shows how often and when it was last paid. Pull every wallet you ever paid into the book with one tap, sort by name, last paid or most paid. Nothing leaves the phone. NOTES, TAGS, SEARCH Attach notes and tags to every run and every saved list. Search your history by name, note, tag, address or contact. Find last month's airdrop in 2 seconds. SCHEDULE AND REPEAT Save recipient lists as campaigns with a date and a time. Daily, weekly or monthly. The app reminds you when a campaign is due and opens it ready to send. BACKUP THAT IS YOURS One tap writes everything the app holds, runs, campaigns, contacts, photos and settings, into a single file encrypted with a password you choose (AES-256-GCM, PBKDF2). Restore it on a new phone and the workspace is back. The file is useless without the password. STRICT BY DESIGN The importer refuses to guess. An address that does not end cleanly, an amount where "1,000" could mean two different things, a third CSV column that looks like a number: all of these become a visible error instead of a wrong transfer. You choose whether a comma or a point is your decimal separator. WHAT ELSE IS IN IT - SOL and any SPL token, including Token-2022, with metadata and balances read from the chain - Transaction simulation before sending - Fresh wallet warning: the dry run tells you how many recipients have never held SOL or this token, so a typo does not become a payment to nowhere - Launcher shortcuts: long press the icon for New run, Contacts or Campaigns - Screen stays on while a run is sending - Adjustable priority fee, optional memo, your own RPC endpoint, with a built in guide to a free Helius key when the public RPC is too slow - Signing through Mobile Wallet Adapter: your keys never touch this app - English, German, French, Italian and Spanish FEES A run costs 0.05 SOL plus 0.003 SOL per recipient, charged inside the same transactions that do the sending, plus the usual Solana network fee. Everything, amounts included, comes out of the sending wallet, and the dry run tells you the exact total and the exact shortfall before you sign. No subscription, no account, no sign-up. PRIVACY There is no server. No account, no telemetry, no analytics. Recipient lists, contacts, photos, run history and campaigns stay in the app's private storage on your device. The only network connections the app makes are to the Solana RPC endpoint you selected. MASTRsender is made by MASTR Labs: mastrlabs.com, mastrapps.com, mastrtrade.com, mastrpass.xyz.
