How to Add a New Network to a Crypto Wallet?

MetaMask Network Configuration Process

1. Launch MetaMask and unlock your wallet using the correct password.

2. Click the network selector located in the top center of the interface to open the dropdown menu.

3. Scroll down and select “Add Network” to initiate manual configuration.

4. Choose “Custom RPC” and input the required parameters: network name, RPC URL, chain ID, currency symbol, and block explorer URL.

5. Confirm all fields are correctly entered before clicking “Save” — an incorrect RPC URL will prevent DApp interaction and transaction relaying.

ChainList Integration Method

1. Navigate to chainlist.wtf using a supported browser.

2. Click “Connect Wallet” in the top-right corner and approve the connection request from MetaMask.

3. Use the search bar to locate the target blockchain, including testnets when “Include Testnets” is enabled.

4. Click “Add to MetaMask” on the relevant network card and confirm the prompt in your wallet extension.

5. The network appears instantly in MetaMask’s network list without requiring manual parameter entry.

Keplr Wallet Setup for Cosmos Ecosystem

1. Install the Keplr browser extension from the official Chrome Web Store link.

2. Pin the extension icon to your browser toolbar for quick access.

3. Select “Create a new account” and choose 24-word mnemonic phrase length.

4. Record the mnemonic phrase securely — it is the sole recovery mechanism for Secret Network assets.

5. After creation, switch the network dropdown to “Secret Network” to reveal your secret1... address format.

Arbitrum One Mainnet Manual Addition

1. Open MetaMask settings and go to “Networks” > “Add Network” > “Add a network manually”.

2. Enter “Arbitrum One” as the network name and https://arb1.arbitrum.io/rpc as the RPC URL.

3. Input chain ID 42161, currency symbol “ETH”, and explorer URL https://explorer.arbitrum.io.

4. Save the configuration and verify the network appears in the dropdown list.

5. Ensure ETH is held on Ethereum L1 to cover gas fees before initiating cross-chain deposits.

Emblemai Agent API Wallet Management

1. Access the Emblemai agent hustle API endpoint at https://api.agenthustle.ai.

2. Include your valid x-api-key header in every request.

3. Query wallet balances across Solana, Ethereum, Base, BSC, Polygon, Hedera, and Bitcoin using /balance/{chain}/{address}.

4. Execute token swaps or transfers by sending POST requests to corresponding endpoints with chain-specific payloads.

5. Retrieve portfolio analysis reports without storing private keys — all operations remain non-custodial and client-side signed.

Frequently Asked Questions

Q: Can I add multiple testnets simultaneously using ChainList?A: Yes. ChainList allows bulk addition of testnets after connecting your wallet. Each network requires individual confirmation in MetaMask.

Q: Why does my Keplr wallet show zero balance even after importing the correct mnemonic?A: The wallet must be explicitly connected to Secret Network. Switching the network selector to “Secret Network” triggers on-chain balance synchronization.

Q: Is it safe to use the same mnemonic phrase across MetaMask and Keplr?A: Technically possible but strongly discouraged. Cross-wallet reuse increases exposure surface and violates self-custody best practices.

Q: What happens if I enter an invalid chain ID during manual network setup?A: Transactions will fail silently or revert with “invalid chain ID” errors. The wallet may display zero balances or refuse to sign any payload.
