# RPC API

Blockdaemon’s RPC API provides secure, high-availability JSON-RPC access to 20+ blockchain protocols without running your own nodes. It powers institutional workloads that need reliable reads, fast transaction submission, and strong SLAs.

## Use the RPC API to

* Read on-chain data (balances, transactions, blocks)
* Submit transactions
* Call protocol-specific methods across EVM, Bitcoin-like chains, Solana, and more.
