Our features
Auto-conversion
Customers pay in any crypto they like. You receive stablecoins, automatically converted at the market rate
Smart payment matching
If a payer sends the wrong asset, or chooses the wrong network among EVM chains, we still credit the invoice as paid.
Underpayment tolerance
If a payer sends slightly less than the invoice amount, we still mark it as paid within the tolerance you set.
Static wallets
A permanent wallet address instead of generating a new invoice each time. Perfect for SaaS — recurring payments, subscriptions, and donations.
Event notifications
Webhooks, email and Telegram alerts with per-event rules: created, paid, underpaid, expired or converted.
Team access
Invite teammates into a project with personal accounts and role-based permissions.
Payment Gateway fees
No setup or monthly fees — only a per-transaction commission tailored to your business.
