How to Add Networks to Rabby Wallet?

Network Configuration Interface

1. Launch Rabby Wallet extension in Chrome or Edge browser after successful installation.

2. Click the Rabby icon located at the top-right corner of the browser toolbar to open the wallet interface.

3. Navigate to the network selector dropdown menu situated beside the wallet address display area.

4. Select “Add Network” from the bottom of the dropdown list to access the manual network configuration panel.

5. Input all required parameters including Network Name, RPC URL, Chain ID, Currency Symbol, and Block Explorer URL.

Predefined Network Support

1. Rabby Wallet ships with built-in support for Ethereum Mainnet, Arbitrum One, Optimism, Polygon PoS, Base, and BSC.

2. Each preconfigured network includes verified RPC endpoints and standardized token lists for seamless interaction.

3. Users can switch between these networks instantly without reconfiguration or confirmation prompts.

4. The wallet automatically detects and displays balances across all enabled chains in a unified dashboard view.

5. Network icons appear next to asset names to visually indicate chain origin without requiring manual labeling.

Risk-Aware Transaction Preview

1. Before signing any transaction, Rabby Wallet renders a detailed preview showing exact balance changes per chain.

2. The preview highlights potential contract-level risks such as unverified tokens, suspicious approvals, or abnormal gas estimates.

3. Users receive inline warnings if the target network differs from the currently selected one during DApp interaction.

4. All cross-chain bridge actions trigger an explicit network context switch notification before proceeding.

5. The wallet blocks transactions targeting unsupported or misconfigured RPC endpoints by default.

Chainlist Integration Workflow

1. Open Rabby Wallet and click “Connect Wallet” on chainlist.org to initiate secure wallet binding.

2. Search for desired blockchain using the site’s search bar—results include both mainnets and testnets.

3. Click “Add to Rabby” next to the target network entry to trigger automatic parameter injection.

4. Confirm the addition via Rabby’s native signature prompt, which verifies chain metadata integrity before saving.

5. Newly added networks appear immediately in the network selector and retain persistent storage across sessions.

Testnet Configuration Procedures

1. Access the “Networks” tab inside Rabby Wallet settings to manage test environments separately from production chains.

2. Enable “Show Testnets” toggle to expose Sepolia, Holesky, Arbitrum Sepolia, and Optimism Sepolia options.

3. Import faucet tokens directly through integrated links displayed alongside each active testnet listing.

4. Transactions executed on testnets carry distinct visual indicators—including purple-colored status badges—to prevent accidental mainnet confusion.

5. Rabby Wallet enforces strict separation between testnet and mainnet private key derivation paths.

Frequently Asked Questions

Q: Can I add custom RPC endpoints not listed on Chainlist?A: Yes. Manual network addition supports fully custom configurations including self-hosted or third-party RPC services.

Q: Does Rabby Wallet support EIP-3085 wallet_addEthereumChain requests from DApps?A: Yes. It natively handles wallet_addEthereumChain calls and validates all parameters before applying changes.

Q: What happens if I input an incorrect Chain ID during manual setup?A: The wallet rejects the configuration and displays an error indicating mismatched chain identifier and expected network identity.

Q: Are network settings synced across devices when using cloud backup?A: No. Network preferences remain local to each browser instance and are excluded from encrypted cloud backups for security reasons.
