Phantom Wallet uses RPC endpoints to fetch blockchain data—balances, transaction status, token metadata, NFT data—and to submit signed transactions.
By default, Phantom connects to Solana’s public mainnet RPCs. But you can change these network connections or RPC URLs for various reasons.
Switching network modes could mean toggling between Mainnet Beta, Devnet, or Testnet, which are distinct Solana environments. Alternatively, you might swap in a custom RPC URL to connect through a third-party node provider.
Understanding this is key before you start messing with settings: the network defines which blockchain data you interact with, and the RPC controls how your wallet communicates with that network's nodes.
Why Change RPC Settings?
You might ask: "Why bother changing the RPC? Doesn’t the default just work fine?"
In my experience, it mostly does. But sometimes it doesn’t.
Three common reasons users switch RPC endpoints or networks in Phantom Wallet include:
Performance tuning: If the default RPC is lagging or failing, switching to a faster or less congested custom RPC can speed up transactions and wallet refreshes.
Access to alternative networks: Developers or testers often need to connect to Devnet or Testnet instead of Mainnet Beta to try new apps or features without risking real tokens.
Improving fee calculation and transaction reliability: Some RPC providers offer better gas estimation, lower error rates, or custom features that affect how Phantom displays network fees and transaction statuses.
Of course, changing RPCs isn’t risk-free. Using unreliable or malicious RPCs can expose you to incorrect data or censorship. So it’s a balance.
Step-by-Step: How to Change RPC in Phantom Wallet
Here’s how to switch RPCs or networks in Phantom on desktop or mobile:
Open Phantom Wallet. Unlock your wallet.
Click on the network dropdown. On desktop, it’s near the top center labeled "Mainnet Beta" or current network. On mobile, you’ll find it under settings or at the top of the screen.
Select "Add / Manage Networks" or "Custom RPC". Not all versions label this the same, but look for options to add or modify networks.
For built-in networks: Choose from Solana Mainnet Beta, Devnet, Testnet.
For a custom RPC: Enter the RPC URL provided by your node provider.
Example:
https://solana-mainnet.rpcprovider.io
Save and switch to the new network or RPC.
After switching, you might notice the wallet refreshes balances and transaction history. This is because Phantom is now pulling data from the new endpoint.
If you face the network fee not loading or balance not updating, double-check your RPC URL for typos or try another known endpoint.
Using Custom Networks in Phantom Wallet
Phantom lets you add custom networks mostly used for testing or specialized use cases. Let’s clarify the options:
| Network Type |
Purpose |
Typical Use Case |
| Mainnet Beta |
Live Solana network for real assets |
Daily trading, staking, NFTs, DeFi on Solana mainnet |
| Devnet |
Developer testing and experiments |
Smart contract dev, beta dApps without token loss |
| Testnet |
Testing before deployment |
Larger-scale stress tests and validation |
| Custom RPC |
Any Solana-compatible node |
Using private nodes for privacy, speed, or reliability |
Using custom RPCs can improve wallet responsiveness if the default endpoint is slow or unreliable. However, the main catch is trust. You’re effectively routing all your queries and transactions through that node.
If it’s malicious or compromised, it could feed you faulty information or disrupt activity. That’s why, in my experience, it’s safer to stick with well-known RPC providers unless you’re running your own node.
Troubleshooting Common Network Issues
Phantom users occasionally encounter these network hiccups:
Balance or token data not loading. Usually means RPC downtime or connectivity issues. Switching to a different RPC in Phantom can fix this.
Network fee not loading. This happens when the gas estimation from the RPC endpoint fails. Try another RPC URL to resolve it.
Transaction stuck or failed. Bad RPCs can cause submission errors. Also verify network selector matches intended blockchain environment.
Phantom wallet not switching networks or stuck. Clearing cache or restarting Phantom sometimes helps. Check you’re running the latest version.
If all fails, resetting or reinstalling Phantom (and restoring with your seed phrase) might save the day—but always keep that phrase secure.

Impact of RPC Choices on Phantom Wallet Performance
Let’s talk performance because this shows why RPC isn’t just a geeky setting.
Phantom’s speed in updating balances, loading token metadata, and completing swaps depends on the RPC’s response time and node health.
Choosing a slow or geographically distant RPC is like trying to surf the web on dial-up. Delays in reading your token portfolios or estimating fees can frustrate daily usage, especially when swapping or interacting with DeFi dApps.
But faster isn't always more secure. I've noticed that some public RPCs prioritize uptime but occasionally miss transaction finality updates, leading to phantom hung transactions.
By customizing RPCs, you can experiment with different providers to find a compromise between speed and reliability.

Security Considerations When Configuring Networks
Changing network settings or adding custom RPCs comes with security trade-offs.
To be blunt: Phantom itself doesn’t control RPC security. The nodes you connect to see your wallet's public addresses and read your transactions in real-time.
A compromised RPC node can serve outdated data or attempt phishing by injecting fake dApps—though Phantom’s in-built phishing detection helps here.
My rule? Only trust RPC endpoints from reputable providers or your own infrastructure.
Avoid random RPC URLs found in forums or Telegram groups. And regularly check your token approvals in Phantom’s security review features to guard against malicious smart contracts exploiting stale data.
Best Practices for Managing Phantom Wallet Network Settings
To wrap, here are best practices based on hands-on use:
Stick to default networks unless you have a clear reason to change. Mainnet Beta is stable for most.
If using custom RPCs, verify their source and uptime. Test swaps or small stakes first.
Regularly switch networks to Devnet or Testnet only for development or testing. Don’t accidentally leave it on these when expecting real assets.
Monitor wallet behavior after switching RPCs. Delays or errors warrant trying other nodes.
Back up your seed phrase securely before messing with network settings. In case of reinstall.
Use Phantom’s built-in transaction simulation and approval revocation to minimize risks associated with faulty RPC data.
Keep your Phantom wallet updated. Recent versions improve how network switching and RPC configurations work.
By managing network settings conscientiously, you maintain a smoother and safer DeFi experience.
Conclusion
Changing RPC and network settings in Phantom Wallet isn’t something every user must do—but understanding how to do it empowers you to troubleshoot, optimize performance, or participate in Solana development environments.
Remember, Phantom Wallet’s default configurations work well for daily activities, but knowing how to switch networks or add custom RPCs gives you flexibility and control.
