# Blockchain networks and chain IDs supported by CoinVoyage

> Complete list of every blockchain CoinVoyage supports for payments and settlement, including chain IDs, testnet availability, and upcoming networks.

CoinVoyage accepts payments from and settles to a growing set of blockchain networks. Each network is identified by a chain ID that you use when creating PayOrders or requesting quotes. The table below lists every currently supported chain, its ID, and whether a testnet is available. If you need support for a network not listed here, contact the team at [help@coinvoyage.io](mailto:help@coinvoyage.io).

## Supported networks

| Chain                     | Chain ID         |
| ------------------------- | ---------------- |
| Bitcoin                   | `20000000000001` |
| Solana                    | `30000000000001` |
| Ethereum Mainnet          | `1`              |
| Optimism                  | `10`             |
| Arbitrum                  | `42161`          |
| Base                      | `8453`           |
| Binance Smart Chain (BSC) | `56`             |
| Polygon                   | `137`            |
| Sui                       | `30000000000002` |

## Using chain IDs in your integration

When you create a PayOrder or request payment details, you reference a network by its chain ID. The SDK exports a `ChainId` enum so you don't have to remember raw numbers:

```typescript theme={null}
import { ChainId } from "@coin-voyage/paykit/server";

// ChainId.SUI === 30000000000002
// ChainId.ETH  === 1
// ChainId.SOL  === 30000000000001

const { data } = await apiClient.createDepositPayOrder({
  intent: {
    asset: {
      chain_id: ChainId.SUI,
      address: null, // null = native token
    },
    amount: { token_amount: 10 },
    receiving_address: "0xYourAddress",
  },
});
```

## Coming soon

CoinVoyage is actively expanding network coverage. Networks currently in integration include:

* **AVAX** — Avalanche
* **Tron**
* Additional Ethereum L2s

<Info>
  Network availability may differ between the `production` and `development`
  environments. The development environment may include early-access chains not
  yet available in production.
