hw-app-hash
Ledger Hardware Wallet JavaScript bindings for Provenance, based on LedgerJS.
Using LedgerJS for Provenance
Here is a sample app for Node:
const Transport = require("@ledgerhq/hw-transport").default;
const Provenance = require("hw-app-hash_token").default;
const getPublicKey = async () => {
const hash_token = new Provenance(await Transport.create());
return await hash_token.getPublicKey("44'/505'/0'/0/0");
};
const signTransaction = async () => {
const transport = await Transport.create();
const hash_token = new Provenance(await Transport.create());
return await hash_token.signTransaction(
"44'/505'/0'/0/0",
"<transaction contents>"
);
};
const getVersion = async () => {
const transport = await Transport.create();
const hash_token = new Provenance(await Transport.create());
return await hash_token.getVersion();
};
const doAll = async () => {
console.log(await getPublicKey());
console.log(await signTransaction());
console.log(await getVersion());
};
doAll().catch(err => console.log(err));API
