Claude Dev Suite Claude Dev Suite Bitcoin Libraries Rust Bitcoin

rust-bitcoin

The foundation Rust crate for Bitcoin. Used by BDK, LDK, miniscript-rs, electrs, etc. Stable, comprehensive.

Repo: github.com/rust-bitcoin/rust-bitcoin.

Install

[dependencies]
bitcoin = "0.32"   # check current; API stabilizing

Key types

• Transaction, TxIn, TxOut, OutPoint.
• Script, ScriptBuf, Address, Network.
• Block, BlockHash, BlockHeader.
• secp256k1::SecretKey, secp256k1::PublicKey.
• bip32::ExtendedPrivKey, ExtendedPubKey, DerivationPath.
• psbt::Psbt (BIP174).

Quick examples

Address generation

use bitcoin::{Address, Network};
use bitcoin::secp256k1::{Secp256k1, SecretKey, PublicKey};
use bitcoin::PrivateKey;

let secp = Secp256k1::new();
let sk = SecretKey::from_slice(&[1u8; 32]).unwrap();
let pk = PublicKey::from_secret_key(&secp, &sk);
let addr = Address::p2wpkh(&PublicKey::new(pk), Network::Bitcoin).unwrap();
println!("{}", addr);   // bc1q...

Parse + construct tx

use bitcoin::{Transaction, consensus::encode};

let raw = hex::decode("01000000...").unwrap();
let tx: Transaction = encode::deserialize(&raw).unwrap();
println!("txid: {}", tx.compute_txid());

let bytes = encode::serialize(&tx);

Sign with secp256k1

let secp = Secp256k1::new();
let msg = bitcoin::secp256k1::Message::from_digest_slice(&hash).unwrap();
let sig = secp.sign_ecdsa(&msg, &sk);

Modules

• consensus — wire format encode/decode.
• blockdata — block / tx / script.
• network — message types, magic bytes.
• psbt — partially-signed tx.
• bip32 — HD derivation.
• taproot — Taproot (TaprootBuilder, ControlBlock).
• address — addr parsing + generation.

Use cases

• Wallet / signer / explorer code in Rust.
• Backend services consuming Bitcoin data.
• Foundation for higher-level libs (BDK, LDK).

Common pitfalls

• API churn between minor versions in 0.x range. Pin carefully.
• Script (zero-cost wrapper) vs ScriptBuf (owned) — most APIs take &Script.
• Network mismatch errors when building cross-network apps.
