# Supported networks

WalletChan ships with a broad EVM network registry and also supports custom
networks. A network being visible does not mean every remote service or
advanced feature supports it.

## Built-in mainnets

| Network | Chain ID | Notes |
| --- | ---: | --- |
| Ethereum | 1 | Swaps, EIP-7702, Bankr |
| Abstract | 2741 | Swaps |
| Arbitrum | 42161 | Swaps, EIP-7702, Bankr |
| Avalanche | 43114 | Swaps |
| Base | 8453 | Swaps, EIP-7702, Flashblocks, Bankr |
| Berachain | 80094 | Swaps, EIP-7702 |
| Blast | 81457 | Hidden by default |
| BNB Chain | 56 | Swaps, EIP-7702, Bankr |
| HyperEVM | 999 | Swaps, EIP-7702 |
| Ink | 57073 | Swaps, EIP-7702 |
| Linea | 59144 | Swaps, EIP-7702 |
| Mantle | 5000 | Hidden by default |
| MegaETH | 4326 | Swaps, sync-send optimization, non-standard gas model, Bankr |
| Mode | 34443 | Hidden by default |
| Monad | 143 | Swaps, EIP-7702 |
| Optimism | 10 | Swaps, EIP-7702, Bankr |
| Plasma | 9745 | Swaps |
| Polygon | 137 | Swaps, EIP-7702, Bankr |
| Robinhood Chain | 4663 | Bankr; registry availability may precede general network launch |
| Scroll | 534352 | Hidden by default |
| Sonic | 146 | Hidden by default |
| Tempo | 4217 | USD-denominated EVM metadata; no ordinary native-token balance |
| Unichain | 130 | Swaps, EIP-7702, Bankr |
| World Chain | 480 | Swaps |
| ZKsync Era | 324 | Swaps |

Built-in availability, visibility defaults, and service support can change
with WalletChan releases.

## Testnets

WalletChan includes corresponding test networks such as Ethereum Sepolia and
Hoodi, Base/Arbitrum/Optimism/Unichain Sepolia, Avalanche Fuji, Polygon Amoy,
and testnets for the other built-in families. Testnets ship hidden and must be
enabled explicitly from **Settings → Chains**.

## Custom networks

Add a network from Settings or approve a valid dapp `wallet_addEthereumChain`
request. You can set:

* Network name and chain ID.
* One or more saved HTTPS/WSS RPC endpoints.
* Block explorer URL.
* Native currency name, symbol, and decimals.
* Optional EIP-7702 delegate configuration where the chain supports it.
* Developer-only impersonated transaction support for a specific RPC.

See [Networks and RPCs](/settings/networks-and-rpcs).

## Why features differ

* **Swap and bridge** availability comes from current quote/catalog providers.
* **Safe** needs a verified service/onchain configuration for that chain.
* **Fee tokens** require compatible smart-account/paymaster infrastructure.
* **EIP-7702** and atomic batches require chain support or an explicitly
  configured delegate.
* **Force inclusion** applies only to eligible OP Stack routes and account
  paths.
* **Bankr** remote signing only accepts networks supported by the Bankr API.

WalletChan hides or explains an unavailable action rather than treating the
network registry as a blanket promise.
