Direct Solana blockchain interaction via JSON-RPC — account lookups, token balances, transaction submission, and program queries

Solana RPC — Direct Blockchain Interaction The Solana JSON RPC API provides direct read/write access to the blockchain. Use it for account state queries, token balance lookups, transaction building and submission, and program account enumeration. This is the low level foundation when higher level APIs (Birdeye, Helius, SolanaTracker) don't have the data you need. Quick Start RPC Providers Provider Free Tier Paid Notes Helius 50K credits/day $49+/mo Enhanced RPCs, DAS API QuickNode Limited $49+/mo Multi chain, WebSocket Triton No free tier ~$300+/mo Yellowstone gRPC bundled Shyft Limited $49+/mo Yellowstone gRPC bundled Alchemy 300M CU/mo Scaling Good free tier Public (mainnet beta) Free — Rate limited, unreliable Recommendation : Use Helius or QuickNode for development. Never use public RPC for production trading. Core Read Methods Account & Balance Token Accounts Transaction Data Block & Slot Program Accounts Warning : getProgramAccounts without filters can return millions of results and timeout. Always use dataSize and/or memcmp filters. Priority Fees Write Methods Send Transaction Transaction Confirmation Commitment Levels Level Description Use When processed Single node confirmation Speed over safety confirmed Supermajority (2/3+) Default for trading finalized Maximum supermajority + 31 slots Critical operations Always specify commitment explicitly. Default varies by provider.
