# Chains & Contracts

> Supported chains, their identifiers, and Mayan's deployed contract addresses.

Every chain Mayan supports, with the identifiers you pass to the API and the contracts you interact with.

<Note>
  Chains are identified by their **Wormhole chain ID**, not their EVM chain ID. Base is `30`, not `8453`. Passing an EVM chain ID where a Wormhole chain ID is expected will be rejected or produce the wrong result.
</Note>

## Supported chains

| Chain           | Name in API | Wormhole chain ID | EVM chain ID |
| --------------- | ----------- | ----------------- | ------------ |
| Solana          | `solana`    | 1                 | n/a          |
| Ethereum        | `ethereum`  | 2                 | 1            |
| BNB Smart Chain | `bsc`       | 4                 | 56           |
| Polygon         | `polygon`   | 5                 | 137          |
| Avalanche       | `avalanche` | 6                 | 43114        |
| Sui             | `sui`       | 21                | n/a          |
| Arbitrum        | `arbitrum`  | 23                | 42161        |
| Optimism        | `optimism`  | 24                | 10           |
| Base            | `base`      | 30                | 8453         |
| Linea           | `linea`     | 38                | 59144        |
| Unichain        | `unichain`  | 44                | 130          |
| HyperEVM        | `hyperevm`  | 47                | 999          |
| Monad           | `monad`     | 48                | 143          |
| Fogo            | `fogo`      | 51                | n/a          |
| HyperCore       | `hypercore` | 65000             | n/a          |

Support differs by direction. `GET https://sia.mayan.finance/v10/init` returns the live list with `originActive` and `destinationActive` per chain. Read it rather than assuming a chain works both ways.

## EVM contracts

The Forwarder is the single entry point for EVM swaps, and is deployed at the same address on every supported EVM chain.

| Contract        | Address                                      |
| --------------- | -------------------------------------------- |
| Mayan Forwarder | `0x337685fdaB40D39bd02028545a4FfA7D287cC3E2` |

Approve the Forwarder for ERC20 inputs before swapping. See [Forwarder Contract](/integration/forwarder-contract).

### Deposit address contracts

| Contract                              | Address                                      |

## API endpoints

| Service                | URL                                     |
| ---------------------- | --------------------------------------- |
| Quote API              | `https://price-api.mayan.finance/v3`    |
| Explorer API           | `https://explorer-api.mayan.finance/v3` |
| Chain and token config | `https://sia.mayan.finance/v10/init`    |

## Tokens

Any token with a contract address is routable. `GET https://price-api.mayan.finance/v3/tokens?chain=solana` returns the whitelisted list for a chain, and dropping the `chain` parameter returns every chain.

## Verifying addresses

Every address on this page is exported by the SDK as `addresses`, so you can read them at runtime rather than hardcoding:

```typescript theme={null}
import { addresses } from "@mayanfinance/swap-sdk";

console.log(addresses.MAYAN_FORWARDER_CONTRACT);
```

All contracts are public and audited. See [Security & Audits](/resources/audits).
