Getting Started with Bitcoin (Embedded Daemon)

Overview

RPCClient provides a high-level interface for sending commands to a Bitcoin node using the JSON-RPC protocol. It supports multiple transports: HTTP for remote nodes and a direct in-process bridge for embedded daemons.

Transport selection can be explicit (via init(transport:)) or automatic (via init(url:username:password:)), which picks the direct bridge when available and falls back to HTTP.

RPC methods are organized into extensions matching Bitcoin Core’s RPC categories:

RPCClient+Blockchain.swift — Blockchain RPCs (incl. mempool)
RPCClient+Control.swift — Control RPCs
RPCClient+Generating.swift — Generating RPCs
RPCClient+Mining.swift — Mining RPCs
RPCClient+RawTransactions.swift — Rawtransactions RPCs (incl. PSBT)
RPCClient+Util.swift — Util RPCs
RPCClient+Network.swift — Network RPCs
RPCClient+Wallet.swift — Wallet RPCs

Note

Targets Bitcoin Core v31.x. All RPCs are covered.
