How to add a custom RPC network to Trust Wallet?

Adding a Custom RPC Network to Trust Wallet

Trust Wallet allows users to interact with various blockchain networks beyond the default ones. Adding a custom RPC network enables access to decentralized applications and tokens on emerging or niche blockchains. This process requires specific network details and careful input to ensure connectivity and security.

Step-by-Step Guide to Configure a New Network

Access the side menu by tapping the profile icon in the top-left corner. Select 'Settings' from the list, then choose 'Networks' under the 'Wallet' section.

2. Scroll down and tap on 'Add Custom RPC Network'.

This option is located at the bottom of the networks list. Tapping it opens a form where you can enter the required blockchain parameters.

3. Fill in the network details accurately.

You must provide the Network Name, RPC URL, Chain ID, Symbol, Block Explorer URL, and optionally the decimals for the native token. These values are typically available on the official website of the blockchain you're adding.

4. Save the configuration after verifying all fields.

Once all information is entered correctly, tap 'Save' to add the network to your wallet. It will now appear in your network list and can be selected when managing assets.

5. Add the native token if it doesn't appear automatically.

Some networks require manually adding the main token. Go to the 'Tokens' tab, search for the token symbol, and enable it to track balances and make transactions.

Common Mistakes When Setting Up Custom Networks

The Chain ID must match the one used by the blockchain. An incorrect value prevents transaction signing or causes failed broadcasts. The RPC URL should be a reliable node endpoint, preferably provided by the network’s developers.

2. Entering an invalid block explorer URL.

This field is used to link transaction hashes to a public explorer. If left blank or filled incorrectly, you won’t be able to view transaction details externally.

3. Ignoring token decimal settings.

Most tokens use 18 decimals, but some networks use different values. Misconfiguring this may lead to display errors in balance tracking.

4. Saving unverified network configurations.

Always double-check inputs against official documentation. A typo in the RPC URL could expose your wallet to phishing attempts if the endpoint is malicious.

5. Assuming compatibility with Ethereum-based dApps without verification.

Even if a network supports EVM, not all dApps integrate with it. Confirm that the platform you intend to use explicitly supports the network before proceeding.

Tips for Securing Your Custom Network Setup

Public nodes may log your activity. Prefer official providers or run your own node when possible to maintain privacy.

2. Regularly verify network stability.

If transactions fail consistently, the RPC server might be unreliable. Consider switching to a backup endpoint listed by the network’s team.

3. Monitor for network updates affecting Chain ID or RPC URLs.

Blockchains undergoing upgrades may change these parameters. Staying informed ensures continued access to your assets.

4. Avoid sharing custom network configurations publicly.

While most data is non-sensitive, exposing internal setups could assist attackers in crafting targeted scams.

5. Test with small transactions first.

Before moving significant funds, send a minimal amount to confirm everything works as expected across wallets and dApps.

Frequently Asked Questions

How do I find the correct RPC URL for a blockchain?Check the official documentation or developer portal of the blockchain. Community forums and GitHub repositories often list verified endpoints.

Can I remove a custom network from Trust Wallet?Yes. Go to Settings > Networks, locate the custom network, and swipe left to delete it or tap an edit option if available.

Why isn't my token balance showing after adding the network?The native token may need to be manually enabled. Visit the Tokens section, search for the symbol, and toggle it on to display the balance.

Is it safe to add unknown networks to my wallet?Only add networks you trust. Malicious configurations could redirect transactions or expose metadata. Always validate details through official channels.
