WalletPress

Multi-chain wallet generation engine supporting 55 blockchains. MIT open source. BIP39/BIP32/BIP44 compatible.

What It Does

Generates cryptographically secure wallets on 55 chains from a single API. Each wallet is a full keypair — private key, public key, address — on your choice of blockchain. Keys are derived from CSPRNG entropy per BIP39 standards and can optionally be derived deterministically from a mnemonic phrase.

Requirements

• Python 3.10+ (3.12 recommended)
• OpenSSL 3.x (for Argon2id encryption)
• SQLite 3.37+ (WAL mode)
• 1GB RAM minimum (4GB recommended for vault > 10,000 wallets)

Build & Run

# Dependencies vary by OS. You'll need python3-dev, libssl-dev, build-essential.
# Platform-specific package names are not documented here.

pip install -r requirements.txt

# Generate credentials yourself:
# WP_ADMIN_KEY — 32+ byte hex string for API authentication
# WP_VAULT_PASSWORD — 20+ char passphrase for AES-256-GCM key encryption
# These have no defaults. The server will not start without them.

export WP_ADMIN_KEY=<your 32+ byte hex key>
export WP_VAULT_PASSWORD=<your 20+ char passphrase>
