@cosmonauts/auth

Auth

Authentication for web3 accounts.

Usage

npm install @cosmonauts/auth

Taking secp256k1 as example.

// import * from "@cosmonauts/auth"; // Error: use sub-imports, to ensure small app size
import { Secp256k1Auth } from "@cosmonauts/auth/secp256k1";

const auth = Secp256k1Auth.fromMnemonic("<mnemonic words>", "<HD path>");
const signature = auth.sign(Uint8Array.from([1, 2, 3]));
console.log(signature.toHex());

It's easy to derive cosmos/injective/ethereum network HD path (taking cosmos as example)

// derive with Cosmos default HD path "m/44'/118'/0'/0/0"
const auth = Secp256k1Auth.fromMnemonic("<mnemonic words>", "cosmos");
// is identical to 
const auth = Secp256k1Auth.fromMnemonic("<mnemonic words>", "m/44'/118'/0'/0/0");
