Payanvil is a desktop app that sends USDT (TRC-20) to hundreds of recipients in one run — no web services, no KYC, no third parties holding your funds.
v1 is feature-complete and in final hardening. Release: soon.
Because every existing option asks you to give something up.
Charge $15–50 per batch — and your addresses, amounts and volumes pass through someone else's website. Every single run.
Hold your money on their balance and require KYC once your volume matters. Your funds, their rules.
Built for enterprises: per-contractor monthly fees, compliance workflows, onboarding calls. Overkill when you just need to pay people.
Web multisenders charge per batch, forever. Payanvil is a one-time purchase.
Payanvil asks for your private key — in crypto, that's a red flag. So every line that touches your key or the network is published for audit in payanvil-core.
The key touches exactly two classes — both open source. Kept in memory only, zero-filled after use, never written to disk, never logged. Signing happens locally via trident, the official Tron SDK.
Payment queue and transfer history live in a locally encrypted database. The encryption password is yours. No telemetry, no analytics, no "phone home".
The application talks to exactly these endpoints — nothing else. Verifiable in the open code.
| Endpoint | Purpose |
|---|---|
| Tron node (TronGrid) | Balances, broadcast, confirmations, USDT blacklist check |
| api.binance.com | TRX→USDT rate — only in "fee from recipient" mode |
| CoinGecko | Fallback rate source |
| api.gopluslabs.io | Recipient reputation check (phishing / stolen funds / sanctions) |
| api.telegram.org | Only if you enable the Telegram intake bot — with your own token |
For teams paying contractors, e-commerce paying suppliers, OTC desks and anyone who pays many people in USDT.
Drop a file with names, addresses, purposes and amounts — get a full batch preview before anything is sent.
Run your own bot (your token, your privacy): people send payment requests or files, they land in your queue.
Per-transfer choice of who pays the network fee — recipient-pays mode deducts it from the amount at a rate fixed per batch.
USDT contract blacklist check plus GoPlus reputation screening (phishing, stolen funds, sanctions) before you confirm.
Every batch produces a color-coded report; full searchable history with export — your accounting will thank you.
English, Spanish, Ukrainian, Russian — interface and reports, switchable independently.
One-time purchase. No subscription. No per-batch fees.
Final pricing will be announced at launch.
No and no. Payanvil is a sending tool: you bring your own Tron wallet's private key, the app signs transactions locally and broadcasts them to the network. We never see your key and never touch your funds — there is no server side.
You don't have to take our word: every class that touches the key or the network is published at github.com/Payanvil/payanvil-core. The key is handled by exactly two classes, zeroed after use, and signing goes through the official Tron SDK. Official builds are signed (macOS notarized, Windows code-signed).
The security-critical core is published under the Business Source License — free to read, audit, and use for research. The GUI and convenience features stay closed because that's the product we sell. We're upfront about this trade-off: the goal of the open core is auditability, and it becomes Apache 2.0 automatically in 2030.
Everything — on the Nile testnet. The full application works without a license on testnet, forever. Sending on mainnet requires a license key. That's the whole difference.
v1: USDT (TRC-20) on Tron. Multi-chain support (more networks and tokens) is planned as the next major version — v1 license holders will get an upgrade discount.
