Cross-chain swaps
as a single API.
One endpoint. Multiple aggregated routes. A quoted amount-out at request time. Built for dApps, wallets, and aggregators that want cross-chain liquidity without managing vendor sprawl.
Aggregated routes
We query supported routes in parallel and surface the selected amount-out, with route choice depending on provider availability, amount size, and network state.
Vendor-neutral
One stable API. We absorb upstream changes — pricing, schema, deprecations — so your integration never needs a rewrite.
Deposit-address mode
No wallet SDK required. We create a one-time deposit address; your user sends funds, and deposit detection starts the order flow.
One curl. Five minutes.
Quote a USDT-on-Ethereum → USDT-on-Tron swap. No SDK, no wallet, no on-chain transactions until your user actually wants to swap.
