Security by design
Your money stays safe, in your control
Sendbase is self-custodial, so we never hold or touch your assets. While a swap is in progress, the USDT sits in an on-chain smart-contract escrow that Sendbase cannot drain, freeze, or divert, and it only releases once both sides complete.
- Escrow on every swap. The seller's USDT is locked before the buyer pays, so it can never vanish midway.
- 2-of-3 MPC key shares. Your wallet key is split three ways; the server holds only one and can never act alone.
- Free dispute resolution. If a swap goes wrong, arbitration reviews the evidence and settles it fairly, at no cost.
