@arc76/algorand

Deterministic ARC76 account derivation for Algorand.

Renamed from the arc76 package (v1.x). See the migration guide if you're upgrading.

Usage

npm i @arc76/algorand --save

import { getAccount, getEmailAccount } from "@arc76/algorand";

const account = await getAccount(password); // slot 0
const account1 = await getAccount(password, 1); // slot 1

const emailAccount = await getEmailAccount(email, password); // slot 0

Both functions return an algosdk.Account ({ addr, sk }).

Post-quantum (Falcon-1024) account

import { getFalconAccount, getEmailFalconAccount } from "@arc76/algorand";

const falcon = await getFalconAccount(password); // { address, publicKey, privateKey, salt }
const emailFalcon = await getEmailFalconAccount(email, password, 1);

The same 32-byte ARC76 seed is used as for the Ed25519 account, so leaking the password compromises both - use a different slot to isolate them. Addresses match the .NET and Python packages. Keys work with falcon-1024.

Please use a password of at least 50 characters for real accounts — the account's security is entirely the password's security.

⚠️ Same-curve chains share the literal same keypair. @arc76/algorand and @arc76/solana derive the identical Ed25519 keypair from the same password/email/slot — leaking the key on one of those chains leaks it on the other. Use a different password (or slot) per chain if you need isolation.
