# Corridor matrix

> Curated payment-route and payment-link corridors — origin token to Base or Solana settlement.

Snapshot of curated corridors for [payment routes](/products/payment-routes) and [payment links](/products/payment-links).

<Warning>
  Always call `GET /v1/payment-routes/chains` (or `/v1/collections/chains`) at runtime. This table can lag the live API.
</Warning>

## Settlements

| Network    | Tokens you can receive |
| ---------- | ---------------------- |
| **Base**   | USDC, USDT             |
| **Solana** | USDC, USDT, **EURC**   |

## Origin → settlement

| Origin   | Token | → Base     | → Solana   |
| -------- | ----- | ---------- | ---------- |
| Bitcoin  | BTC   | USDC, USDT | USDC, USDT |
| Tron     | USDT  | USDC, USDT | USDC, USDT |
| BSC      | USDT  | USDC       | USDC       |
| Polygon  | USDC  | USDC       | USDC       |
| Ethereum | USDC  | USDC       | USDC       |
| Base     | USDC  | —          | USDC       |
| Solana   | USDC  | USDC       | EURC       |
| Solana   | EURC  | —          | USDC       |

Use `originChainKey` / `destinationChainKey` from discovery (`bitcoin`, `tron`, `bnb`, `polygon`, `ethereum`, `base`, `solana`) and token codes as `destinationCurrency`.

## Same-chain EURC ↔ USDC

Solana USDC ↔ EURC appears in this matrix as a **collection corridor** (settle into EURC or USDC).

For treasury conversion with indicative rates and a deposit lifecycle, prefer [`POST /v1/swaps`](/products/swaps) instead of a payment route.

## Tokens on a chain but not in routing

Some networks list extra intake tokens (e.g. BNB, ETH, SOL, USDC.e, Polygon USDT). Those are **not** curated corridors unless they appear in `routing` from `/chains`. Do not hardcode them.
