bitcoin-rpc-midas

Type-safe Rust client for Bitcoin Core v30 RPCs, with test node support. Generated from a version-flexible toolchain.

Why Use This?

Compared to hand-written RPC clients, this toolchain offers:

Reduced repetition
Fewer versioning issues
Increased compile-time checks
Support for all Bitcoin p2p networks (mainnet, regtest, signet, testnet, and testnet4)
Improved isolation from environment and port conflicts

Architecture

The crate is organized into focused modules:

client_trait/: Trait definitions for type-safe RPC method calls
node/: Multi-network node management and test client support
test_node/: Integration testing helpers with embedded Bitcoin nodes
transport/: Async RPC transport with error handling and batching
types/: Generated type definitions for all RPC responses

Example

This asynchronous example uses Tokio and enables some optional features, so your Cargo.toml could look like this:

[dependencies]
bitcoin-rpc-midas = "30.0.0"
tokio = { version = "1.0", features = ["full"] }

And then the code:

use bitcoin_rpc_midas::*;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = BitcoinTestClient::new_with_network(Network::Regtest).await?;

    let blockchain_info = client.getblockchaininfo().await?;
    println!("Blockchain info:\n{:#?}", blockchain_info);

    Ok(())
}

Requirements

Requires a working bitcoind executable.

About

This crate is generated by bitcoin-rpc-codegen, which systematically derives type-safe clients from Bitcoin Core's RPC specification. The generator ensures consistency, reduces duplication, and maintains alignment with upstream changes.

Security

This library communicates directly with bitcoind. For mainnet use, audit the code carefully, restrict RPC access to trusted hosts, and avoid exposing RPC endpoints to untrusted networks.
