Definition
A server that applications use to read Solana data and submit transactions. Production apps usually rely on paid RPC providers and configure a fallback.
Why it matters
RPC quality directly affects how fast and reliable your app feels. Public endpoints are rate-limited and not meant for production traffic.
What to check
- Ask which RPC provider the team uses and what the fallback is.
- Ask how RPC errors are monitored in production.
Related terms
- IndexerAn off-chain service that reads Solana transactions and accounts and stores them in a queryable database, so applications can show history and aggregated data quickly.
- Priority feeAn optional extra fee, priced per compute unit, that makes a transaction more likely to be included quickly when the network is busy.
