RPC
Standard Solana JSON-RPC interface for on-demand queries: balances, transaction history, account state, sending transactions.
// updated 2026-06-04
Standard Solana JSON-RPC interface for on-demand queries against the blockchain.
No API tokens. Authentication is by IP allowlist - one IP per Bundle subscription in v1. Requests from IPs outside your whitelist are rejected.
What it's for
Wallets reading balances, explorers showing transaction history, dashboards rendering account state, batch indexers pulling historical data, sending signed transactions. Anything that asks the chain a question and gets an answer.
For a continuous stream of events instead of one-off queries, see gRPC or WebSocket.
