@arc76/core

Shared ARC76 seed derivation (PBKDF2-HMAC-SHA256, 999,999 iterations, 32-byte output) used internally by the per-chain @arc76/* packages (@arc76/algorand, @arc76/ethereum, @arc76/bitcoin, @arc76/bitcoincash, @arc76/solana).

Most consumers should install a chain-specific package instead of this one directly — this package is only useful if you're implementing ARC76 support for a new chain yourself.

Usage

npm i @arc76/core --save

import { deriveSeed, deriveSeedWithEmail } from "@arc76/core";

const seed = await deriveSeed(password); // Uint8Array(32), slot 0
const seed1 = await deriveSeed(password, 1); // slot 1

const emailSeed = await deriveSeedWithEmail(email, password); // slot 0

Password must be at least 16 characters (throws otherwise) — production passwords should be much longer (≥ 50 characters recommended).

⚠️ Same-curve chains share the literal same key material. From the same password/email/slot, @arc76/bitcoin/@arc76/bitcoincash/@arc76/ethereum derive the identical secp256k1 private key, and @arc76/algorand/@arc76/solana derive the identical Ed25519 keypair — leaking one chain's key leaks every other chain sharing its curve. Use a different password (or slot) per chain if you need isolation.
