Introduction

Install the necessary libraries

npm

npm install --save @mempool/mempool.js bip65 bitcoinjs-lib@6 ecpair tiny-secp256k1 varuint-bitcoin @atomic-port/bitcoin

yarn

yarn add @mempool/mempool.js bip65 bitcoinjs-lib@6 ecpair tiny-secp256k1 varuint-bitcoin @atomic-port/bitcoin

HTLC issues a secret and key in advance and uses this to issue a secret lock. When both parties agree to the transaction, the secret and key are exchanged separately, and the key is used to receive a token. This is how the cross-chain swap is performed.

Issue a secret lock

You can publish using this package with the following operations. The output hashPair contains a secret and a proof. The secret is shared in advance, and the proof is issued at a mutually agreed timing.

lock.ts

Unlocking by Proof

With a secret lock, locked assets are withdrawn through a secret proof transaction.
