Understanding RPC Nodes and Performance
Learn about RPC nodes, why performance matters, and how to choose the best provider for your needs.
What Are RPC Nodes?
RPC (Remote Procedure Call) nodes allow applications to interact with blockchains. They process requests like reading balances, sending transactions, and querying smart contracts. Performance varies significantly between providers.
Why Latency Matters
Low latency means faster transaction confirmations and better user experience. For trading or time-sensitive operations, choosing a fast RPC can make the difference between success and failure.
Privacy and RPCs
Your RPC provider sees every request you make: your IP address, your wallet balance checks, and your transactions. Privacy-focused RPCs (like those over Tor or with strict no-log policies) protect your metadata from being harvested.
Censorship Resistance
Some centralized RPC providers comply with OFAC sanctions and will block transactions interacting with "banned" contracts (like Tornado Cash). Using decentralized RPC lists or running your own node ensures your transactions cannot be censored at the entry point.

Go to Settings > Networks > [Select Network] > New RPC URL. You can paste any valid endpoint there. Sites like Chainlist.org make this easy.
It means you are sending too many requests too fast (e.g., refreshing your wallet 100 times a second). The provider blocks you temporarily. Wait a minute or switch providers.
It's the gold standard for privacy and trust (don't trust, verify). However, it requires significant hardware (2TB+ SSD, 16GB RAM) and internet bandwidth.
An archival node stores the entire history of the blockchain state at every block. Standard 'Full Nodes' prune old state to save space. You need archival nodes to query historical balances.
