# Supported Chains & Tokens

Chains and tokens available for Epoch cross-chain intents. Use the SDK's `testnetGraph` and `mainnetGraph` exports for programmatic discovery, or reference the tables below.

For additional chains or tokens beyond the public mainnet set below, [contact the Epoch team](https://epochprotocol.xyz/#contact) or reach out on [Telegram](http://t.me/AkshitOstwal).

Need testnet tokens? Mint via the [Epoch User Dashboard](https://userdashboard.epochprotocol.xyz/) faucets tab ([repo](https://github.com/epochprotocol/epoch-user-dashboard)).

### Testnet chains

<table><thead><tr><th width="222.22265625">Network</th><th>Chain ID</th><th>Gasless Compact deposit</th></tr></thead><tbody><tr><td>Ethereum Sepolia</td><td>11155111</td><td>Yes</td></tr><tr><td>Base Sepolia</td><td>84532</td><td>Yes</td></tr><tr><td>Optimism Sepolia</td><td>11155420</td><td>Yes</td></tr></tbody></table>

**Gasless** applies to the Compact approve + deposit step on testnet when using a local signer and a gasless-enabled allocator. See [Gasless Deposits](/integration-guides/gasless-deposits.md). Verify live support via `GET {apiBaseUrl}/gasless-status`.

#### Miden testnet tokens

Tokens on **Miden** (chain ID `999999999`) are **fungible faucet accounts** and use **6 decimals** (not 18). The faucet account ID below is the token identifier used in intents. Mint them to your Miden account via the [User Dashboard](https://userdashboard.epochprotocol.xyz/) faucets tab. Account IDs are accepted in hex (`0x…`) or bech32 (`mtst1…`) form.

| -------------------------- | -------------------------------- |
| SDK `apiBaseUrl` (mainnet) | `https://api.epochprotocol.xyz/` |

### Mainnet chains

| Chain        | Chain ID |
| ------------ | -------- |
| Base         | 8453     |
| Arbitrum One | 42161    |
| Polygon      | 137      |
| Optimism     | 10       |

### Mainnet tokens

The following tokens are currently supported on **public mainnet** across all supported chains above:

| Symbol |
| ------ |
| USDC   |
| USDT   |
| WETH   |
| DAI    |

Need additional tokens? [Contact the Epoch team](https://epochprotocol.xyz/#contact) or on [Telegram](http://t.me/AkshitOstwal).

## Discovering chains and tokens in code

```typescript
import { mainnetGraph, testnetGraph } from "@epoch-protocol/epoch-intents-sdk";

// Pick graph by chainId (mainnet vs testnet)
// getTokensForChain(chainId) → { symbol, address, decimals }[]
// getChainsFromGraph(chainId) → destination chain options
```

See [SDK Integration Guide](/integration-guides/sdk-integration-guide.md) and [compact-demo-epoch](/integration-examples.md#compact-demo-epoch) for full patterns.

***

## Requesting new chains or tokens

The public mainnet set above covers Base, Arbitrum, Polygon, Optimism and the tokens USDC, USDT, WETH, and DAI. For anything beyond that, [contact the Epoch team](https://epochprotocol.xyz/#contact) or on [Telegram](http://t.me/AkshitOstwal) with:

* Chain name and chain ID
* Token contract addresses and decimals
* Use case (swap, bridge, protocol interaction)

New entries are added to Epoch's routing graph after validation.
