Coin selection library in Typescript
This library adopts the same strategy of Bitcoin Core. It implements Branch and Bound, Knapsack and SRD algorithms and uses a waste metric to decide what solution will be used. Obs.: Some parts of this library is based on coinselect (https://github.com/bitcoinjs/coinselect).
npm i --save coinselection-ts
import { coinselection } from "coinselection-ts"
const fee_rate = 1; //satoshis per byte
const long_term_fee = 10;
const utxos = [
...,
{
txId: '...',
vout: 0,
...,
value: 10000,
script: {
...
}
}
];
const outputs = [
...,
{
address: '1EHNa6Q4Jz2uvNExL497mE43ikXhwF6kZm',
value: 5000
}
];
const { inputs, outputs, fee } = coinselection(utxos, outputs, fee_rate, long_term_fee);
