BOLT12 Decoder

Decode BOLT12 Offers, Invoice Requests and invoices.

The goal is to match the output of the CoreLN decode RPC response.

Code is mostly grabbed from Rusty's BOLT12 repo with some changes and fixes.

Install

yarn add bolt12-decoder npm i bolt12-decoder

Usage

import decodeBolt12 from 'bolt12-decoder'

const bolt12 =
  'lno1qgsqvgnwgcg35z6ee2h3yczraddm72xrfua9uve2rlrm9deu7xyfzrc2q42xjurnyyfqys2zzcssx06thlxk00g0epvynxff5vj46p3en8hz8ax9uy4ckyyfuyet8eqg'

const decoded = decodeBolt12(bolt12)

console.log(decoded)

// {
//   offer_chains: ['06226e46111a0b59caaf126043eb5bbf28c34f3a5e332a1fc7b2b73cf188910f'],
//   offer_description: 'Tips!',
//   offer_id: '45880e501c65e9060d33128d2de1d23ff52ae768b2bcb62bef262d90b741b8cd',
//   offer_issuer: 'AB',
//   offer_node_id: '033f4bbfcd67bd0fc858499929a3255d063999ee23f4c5e12b8b1089e132b3e408',
//   type: 'bolt12 offer',
//   valid: true
// }

Caveats

• Does not decode recurrence (will add once recurrence is added back in to the spec)
• Does not decode invoice_paths and invoice_blindedpay as I could not get it working (I hope to fix this some time soon)
