arc76-solana

Deterministic ARC76 account derivation for Solana.

Usage

pip install arc76-solana

import base58
from arc76.solana import get_account, get_email_account

account = get_account(password)  # slot 0
print(base58.b58encode(account.public_key).decode())  # address
print(base58.b58encode(account.secret_key).decode())  # private key (Phantom export format)

email_account = get_email_account(email, password)

Both functions return a SolanaAccount(public_key, secret_key). The 32-byte ARC76 seed is expanded directly into an Ed25519 keypair (no BIP32/BIP44 hierarchical derivation, no mnemonic):

• public_key — 32-byte Ed25519 public key; base58-encode it for the Solana address.
• secret_key — 64-byte expanded Ed25519 secret key (seed || public_key); base58-encode it for the private key, the same format wallets like Phantom use for private-key export.

The Ed25519 keypair is expanded via PyNaCl (the Python binding for libsodium), matching what tweetnacl (TypeScript) and Chaos.NaCl (.NET) do. Deliberately does not depend on solana-py/solders — only Keypair-equivalent functionality (no RPC) is needed here.

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.
