# Product Overview

> Same-chain and cross-chain stablecoin swaps.

Transit enables stablecoin swaps — both same-chain conversions and cross-chain transfers. Users submit orders on a source chain; the protocol fulfills them on the destination chain (or atomically on the same chain for same-chain routes).

## 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

| Direction           | Offer Asset | Want Asset | Default Protocol Fee |
| ------------------- | ----------- | ---------- | -------------------- |
| Ethereum → Ethereum | USDC        | USDG       | 5 bps (0.05%)        |
| Ethereum → Ethereum | USDG        | USDC       | 5 bps (0.05%)        |
| Ethereum → RH       | USDG        | USDG       | \$0.10 flat          |
| Ethereum → RH       | USDC        | USDG       | 5 bps (0.05%)        |
| Ethereum → RH       | PYUSD       | USDG       | 2.5 bps (0.025%)     |
| RH → Ethereum       | USDG        | USDG       | \$0.15 min + gas     |
| RH → Ethereum       | USDG        | USDC       | 5 bps (0.05%)        |

<Info>
  **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.

  **Same-chain Ethereum routes** (USDC ↔ USDG) settle on Ethereum.

  **All other routes** use a basis-points fee applied to the offer amount. Organizations may have custom fee configurations.
</Info>

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.
