solana-test-validator

A lightweight local Solana validator for development. Runs a single-node cluster on localhost:8899 (RPC) and localhost:8900 (WebSocket). Supports `--clone` to copy mainnet accounts, `--bpf-program` to load programs, and `--reset` to clear state. Processes transactions instantly without PoH delays. Useful for rapid iteration but doesn't simulate network conditions.
