# Networks and RPCs

Open **Settings → Chains**.

## Active and Hidden

Search by network name, numeric/hex chain ID, or RPC host. Built-in networks can
be hidden and restored. Built-in testnets ship hidden until you enable them.
Custom networks can be deleted after confirmation.

Hiding a network removes it from normal selection; it does not move funds or
disconnect a dapp already using another authorized state.

## Add a custom network

Provide network name, chain ID, and an RPC endpoint. Advanced includes explorer,
native symbol/decimals, and developer impersonation. WalletChan checks URL
scheme, private-network policy, duplicate IDs/names, and the chain ID reported
by the RPC.

You can also review a dapp's [EIP-3085 add-chain
request](/dapps/network-and-token-requests).

## Saved endpoints

Each network can retain multiple named endpoints. The endpoint manager lets you:

* See the active/selected endpoint and provider favicon.
* Copy the full URL.
* Add or edit a label and URL.
* Select an existing endpoint.
* Remove an inactive endpoint after confirmation.
* Preserve built-in endpoint selection locally.

Localhost shorthand is accepted where the validated policy allows it. RPC URLs
can contain sensitive provider credentials; do not publish them.

## Verification warnings

WalletChan probes a saved endpoint. It distinguishes unreachable, invalid, and
wrong chain ID. When **Use anyway** is offered, it is an explicit override for
advanced users, not a verification success.

An RPC controls what chain state WalletChan sees and where local signed
transactions are broadcast. A malicious RPC can lie about balances,
simulation, gas, and receipts, although it cannot derive your key from a signed
transaction.

## View-only developer transactions

For an exact localhost/LAN/fork endpoint, you can enable unsigned
`eth_sendTransaction` forwarding. Use it only when the development node already
unlocks or impersonates the address.

The toggle is stored per endpoint. It does not enable signatures, public-RPC
submission, batches, Shield, smart-account grants, or real account ownership.

## RPC issue alert

Home shows a delayed stale-balance/RPC alert for a failing network and links
directly to Edit RPC. Try another trusted endpoint, confirm its chain ID, then
refresh the portfolio.
