How to Add a Custom Network to Trust Wallet?

Understanding Custom Network Configuration

1. A custom network refers to a blockchain not preloaded in Trust Wallet’s default list—such as emerging Layer 1 protocols, testnets, or forked chains.

2. Adding such networks enables users to interact with native tokens, view balances, and transact directly on those chains without switching wallets.

3. Each custom network requires precise parameters: RPC URL, chain ID, symbol, block explorer URL, and currency name.

4. Incorrect configuration may result in zero balance display, failed transactions, or inability to detect contract interactions.

5. Trust Wallet does not validate the legitimacy of custom RPC endpoints—users bear full responsibility for verifying source reliability.

Step-by-Step Manual Network Addition

1. Open Trust Wallet and tap the wallet icon in the bottom navigation bar.

2. Scroll down and select Settings, then choose Networks.

3. Tap Add Network at the top right corner and select Custom RPC.

4. Input the required fields: Network Name, RPC URL, Chain ID (must match the target chain’s official value), Symbol (e.g., “TETH” for a testnet ETH), Block Explorer URL, and Currency Name.

5. Confirm submission—Trust Wallet will instantly apply the network and display it under the active network list.

Common Pitfalls During Setup

1. Entering an outdated or deprecated RPC endpoint causes transaction failures and silent timeouts.

2. Mismatching Chain ID with the actual network leads to rejected signature requests and invalid address derivation.

3. Using HTTP instead of HTTPS for RPC URLs triggers Trust Wallet’s security warning and may block connection attempts.

4. Omitting the block explorer URL disables transaction tracking and receipt verification within the interface.

5. Copy-pasting incomplete JSON-RPC parameters from unofficial forums introduces invisible Unicode characters that break connectivity.

Verification After Network Activation

1. Navigate to the Browser tab and search for a known dApp deployed on the newly added network.

2. Connect your wallet to the dApp and confirm whether the correct network name appears in the connection prompt.

3. Check if token balances reflect accurately by adding a known contract address via Add Token → Custom Token.

4. Initiate a small native token transfer and verify inclusion on the associated block explorer using the transaction hash.

5. Observe whether gas estimation responds dynamically when adjusting slippage or transaction speed settings.

Frequently Asked Questions

Q1: Can I add multiple custom networks simultaneously?Yes. Trust Wallet allows unlimited custom network entries. Each is stored independently and can be toggled on or off under Settings > Networks.

Q2: Why does my custom network disappear after app restart?This occurs only if the network was added during a session where the app crashed before final commit. Re-entering the configuration resolves it permanently.

Q3: Is there a way to export or back up custom network configurations?No native export function exists. Users must manually record all parameters or use third-party note apps with encrypted storage.

Q4: Does adding a custom network expose my private key to external servers?No. Trust Wallet signs transactions locally. RPC endpoints only receive signed raw transaction data—not private keys or mnemonic phrases.
