How to change the RPC URL on Phantom Wallet? (Network Speed)

Accessing Network Settings in Phantom Wallet

1. Open the Phantom Wallet extension or mobile application on your device.

2. Tap or click the three-dot menu icon located in the top-right corner of the interface.

3. Select Settings from the dropdown or modal menu.

4. Navigate to the Networks section, where all configured blockchain networks are listed.

5. Choose the network you wish to modify — for example, Ethereum Mainnet, Solana Mainnet, or a custom RPC endpoint.

Editing an Existing RPC Configuration

1. After selecting the target network, locate and tap the Edit button next to its name.

2. The edit panel displays fields including Network Name, RPC URL, Chain ID, Currency Symbol, and Block Explorer URL.

3. Replace the current RPC URL with a new one — such as a dedicated Infura endpoint, Alchemy URL, or self-hosted node address.

4. Ensure the new URL follows proper syntax: https:// or wss://, followed by domain and optional path or parameters.

5. Save changes using the Save or Update button at the bottom of the form.

Adding a Custom Network with Optimized RPC

1. In the Networks screen, select Add Network or the plus (+) icon.

2. Enter a descriptive name like “Ethereum Fast RPC” or “Solana High-Throughput Mainnet”.

3. Paste a high-performance RPC URL — examples include endpoints from QuickNode, Chainstack, or Geode’s load-balanced infrastructure.

4. Input accurate Chain ID (e.g., 1 for Ethereum, 10 for Optimism, 139 for PulseChain) to prevent transaction failures.

5. Confirm the currency symbol and block explorer link match the intended chain’s conventions before finalizing the addition.

Verifying RPC Performance Impact

1. Switch to the newly configured network using the network selector in the wallet header or home view.

2. Initiate a simple action — such as checking token balances or viewing recent transactions — to test responsiveness.

3. Monitor loading times for on-chain data; faster rendering often indicates lower latency and higher throughput from the RPC provider.

4. Compare gas estimation speed and confirmation feedback across multiple RPC sources under identical conditions.

5. Use browser developer tools or mobile network inspectors to examine actual HTTP request durations and error rates for each endpoint.

Frequently Asked Questions

Q: Can I use multiple RPC URLs for failover in Phantom?A: Phantom does not natively support multi-RPC fallback configurations. Users must manually switch between saved networks if one endpoint becomes unresponsive.

Q: Does changing the RPC URL affect my private keys or wallet address?A: No. The RPC URL only determines how the wallet communicates with the blockchain. Your seed phrase, address, and cryptographic material remain entirely local and unchanged.

Q: Why does my transaction show “pending” longer after switching RPC providers?A: This may occur if the new RPC node is out of sync, rate-limited, or lacks mempool visibility. Verify node health via its public status page or third-party monitoring tools.

Q: Is it safe to enter a custom RPC URL from an unknown provider?A: Exercise caution. A malicious or compromised RPC endpoint could return false balance information or manipulate transaction simulation results. Prefer audited, reputable infrastructure providers.
