Connect without limits

An RPC node is a server that lets your application read and write data to a blockchain without running your own node. BoltRPC provides managed RPC endpoints across 20+ networks so your dApp, protocol, or data pipeline can connect to any chain instantly.

An RPC endpoint is the URL your application sends requests to. It is the gateway between your code and the blockchain. Every wallet connection, every smart contract call, every transaction broadcast goes through an RPC endpoint. The reliability and speed of that endpoint directly affects your application's performance.

JSON-RPC is the standard protocol used to communicate with blockchain nodes. Your application sends a JSON-formatted request (such as eth_getBalance or eth_sendRawTransaction) and the node returns a JSON response. BoltRPC supports the full JSON-RPC specification for every network we provide.

REST APIs use HTTP verbs and stateless resource URLs. JSON-RPC uses a single endpoint and specifies the action inside the request body. For blockchain, JSON-RPC is the native standard. Every Ethereum-compatible chain uses it natively.

Use HTTPS for standard read and write requests. Use WebSocket when you need real-time streaming: subscribing to new blocks, listening for pending transactions, or monitoring contract events without polling. BoltRPC provides WebSocket endpoints on all paid plans.

Archive nodes store the full historical state of the blockchain from genesis. You need archive access if your application queries historical balances, traces past transactions, or runs analytics on old blocks. BoltRPC archive access is available on request across all plans.

BoltRPC uses flat monthly pricing based on request units (RUs). Methods are weighted by server cost with all weights published upfront. Plans start at $49/mo for 30M RUs. No hidden fees, no time-based limits. You know your cost before you build.

BoltRPC supports 20+ blockchain networks including Ethereum, Solana, Polygon, Arbitrum, Base, Optimism, Avalanche, BNB Chain, zkSync Era, Linea, Scroll, Starknet plus more. Full network list at boltrpc.io/networks.

Yes. BoltRPC is used in production by Chainlink, Tiingo, Enjin, Gains Network. Our infrastructure is operated by Matrixed.Link, an ISO/IEC 27001:2022 certified node operator with over 5 years of blockchain infrastructure experience, running at 2 billion daily requests.
