Transit enables cross-chain stablecoin swaps. Users submit orders on a source chain; the protocol fulfills them on the destination chain.

​
How It Works

  1. Get Quote — Call the API to get signed calldata for a submitOrder transaction
  2. Submit — Broadcast the transaction on the source chain (includes messaging fee as value)
  3. Get Fulfilled — The protocol processes the order and credits the destination asset on the target chain

​
Supported Routes

USDG↔USDG routes use flat dollar-based fees. RH → Ethereum includes a dynamic gas component based on current Ethereum gas prices, with $0.15 as the minimum floor.All other routes use a basis-points fee applied to the offer amount. Organizations may have custom fee configurations.
Use GET /v1/transit/routes to fetch the current route configuration programmatically.

​
Minimum Order Size

Orders must be at least $35 USD equivalent in the offer asset.
