@arc76/solana

Deterministic ARC76 account derivation for Solana.

Usage

npm i @arc76/solana --save

import bs58 from "bs58";
import { getAccount, getEmailAccount } from "@arc76/solana";

const account = await getAccount(password); // slot 0
const address = bs58.encode(account.publicKey);
const privateKey = bs58.encode(account.secretKey);

const emailAccount = await getEmailAccount(email, password);

getAccount/getEmailAccount return { publicKey: Uint8Array(32), secretKey: Uint8Array(64) } (an Ed25519 keypair, via tweetnacl's sign.keyPair.fromSeed — no BIP32/BIP44 hierarchical derivation, no mnemonic). Base58-encode publicKey for the address and secretKey for the private key — the same format wallets like Phantom use for private-key export.

Note: this package intentionally does not depend on @solana/web3.js — that SDK's RPC websocket dependency chain currently has an ESM/CommonJS incompatibility (rpc-websockets → uuid v14, ESM-only) unrelated to key derivation. If your app already uses @solana/web3.js for RPC calls, you can wrap this package's output in new web3.Keypair({...}) or web3.Keypair.fromSecretKey(account.secretKey) yourself.

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.
