bdk-tx

This is a transaction building library based on rust-miniscript that lets you build, update, and finalize PSBTs with minimal dependencies.

Because the project builds upon miniscript we support descriptors natively.

Refer to BIP174, BIP370, and BIP371 to learn more about partially signed bitcoin transactions (PSBT).

Example

To get started see the DataProvider trait and the methods for adding inputs and outputs.

use bdk_tx::Builder;
use bdk_tx::DataProvider;

impl DataProvider for MyType { ... }

let mut builder = Builder::new();
builder.add_input(plan_utxo);
builder.add_output(script_pubkey, amount);
let (mut psbt, finalizer) = builder.build_tx(data_provider)?;

// Your PSBT signing flow...

let result = finalizer.finalize(&mut psbt)?;
assert!(result.is_finalized());
