NexFlow › RPC

Free RPC endpoints for 82 chains

Standard JSON-RPC over HTTPS POST for every network below — Solana, Ethereum, Bitcoin, TRON, TON, Cosmos and every major EVM. Baseline reads need no API key: point your wallet, bot, or agent at the endpoint and go. One flat $25/mo key (paid in USDC on Solana or Base — no signup, no KYC) unlocks volume after the first week. We run validators on the chains we route.
