How do I set up a custom RPC node in Phantom?

Connecting a Custom RPC Node to Phantom Wallet

1. Open the Phantom wallet browser extension or mobile application and ensure you are logged in securely. Navigate to the settings menu, typically represented by a gear icon located in the upper right corner of the interface.

2. Within the settings, locate the 'Network' or 'RPC Settings' section. By default, Phantom connects to public Solana endpoints, but users have the option to switch to a custom node for improved performance or privacy.

3. Select the option labeled 'Custom RPC' or 'Add Custom Network.' This will prompt a text field where you can input the HTTP or HTTPS URL of your chosen RPC endpoint. Ensure the URL begins with https:// and is provided by a trusted infrastructure provider such as QuickNode, Alchemy, or your own self-hosted node.

4. After entering the RPC URL, confirm the chain ID corresponds to the Solana network you intend to interact with—mainnet-beta, devnet, or testnet. Mismatched configurations may result in transaction failures or incorrect balance displays.

5. Save the configuration and exit the settings. Phantom will now route all blockchain queries through your specified RPC node. You can verify the connection by initiating a token transfer or checking recent block data within the app.

Benefits of Using a Custom RPC in Web3 Applications

1. Relying on a private or dedicated RPC endpoint reduces dependency on shared public infrastructure, minimizing latency during high-traffic periods on the Solana network. This is particularly valuable when participating in NFT mints or decentralized exchange launches.

2. Improved reliability and uptime are key advantages when using enterprise-grade node providers. Public gateways occasionally face outages or rate limiting, which can disrupt wallet interactions and smart contract calls.

3. Developers integrating Phantom into dApps benefit from predictable API response times when backend services communicate through a controlled RPC channel. This consistency enhances user experience during critical operations like signing and broadcasting transactions.

4. Privacy-conscious users gain increased control over metadata exposure. Public RPCs may log IP addresses and request patterns, while self-hosted or permissioned nodes allow stricter data handling policies aligned with operational security standards.

5. Teams managing large-scale token distributions or validator operations often deploy internal RPC clusters. Connecting Phantom to these systems enables seamless monitoring and execution without competing for bandwidth on community-run servers.

Troubleshooting Common RPC Configuration Issues

1. If transactions fail to confirm after setting up a custom node, double-check the RPC URL for typos or outdated domains. A single character error can redirect requests to non-functional endpoints.

2. Ensure the node supports WebSocket connections if your use case involves real-time updates, such as tracking live order book changes or stake pool rewards. Some lightweight RPC services only handle HTTP POST requests.

3. Clear the browser cache or restart the mobile app if Phantom continues displaying old network data. Stale caches may retain previous blockchain states even after switching RPC sources.

4. Monitor response times using developer tools or third-party dashboards. Abnormally slow query speeds could indicate network congestion, insufficient node resources, or geographical distance between client and server.

5. Contact your RPC provider’s support team if errors persist. Reputable services offer status pages and diagnostic tools to identify downtime, authentication problems, or plan limitations affecting connectivity.

Frequently Asked Questions

Can I use multiple custom RPCs simultaneously in Phantom?Phantom allows only one active RPC connection at a time. However, users can save different network profiles and switch between them manually depending on their current task or environment.

Do I need technical expertise to maintain my own Solana RPC node?Running a full Solana validator or RPC node requires significant hardware resources, Linux system knowledge, and ongoing maintenance. Most individuals opt for hosted solutions unless they operate at institutional scale.

Will changing the RPC affect my wallet's private keys or asset ownership?No. The RPC node acts solely as a communication gateway to the blockchain. Your private keys remain stored locally, and altering the node does not impact asset control or security.

Are there costs associated with using premium RPC providers?Yes. While basic access may be free, high-throughput applications require paid plans offering guaranteed performance, enhanced security, and dedicated support. Pricing varies based on request volume and service level agreements.
