pyzcash 0.1.0a1

Python bindings for librustzcash: address parsing, ZIP-321 URIs, and key derivation

pyzcash

Python bindings for librustzcash. Built with PyO3.

Wraps zcash_address, zip321, and zcash_keys into four Python functions. All crypto runs in Rust.

Install

pip install maturin
git clone https://github.com/craigraw/pyzcash && cd pyzcash
maturin develop

Needs a Rust toolchain. Pre-built wheels coming eventually.

Usage

import pyzcash

# Parse any Zcash address (full checksum validation, not prefix matching)
info = pyzcash.parse_address("tmEZhbWHTpdKMw5it8YDspUXSMGQyFwovpU")
info.address_type  # "p2pkh"
info.network       # "test"
info.is_shielded   # False

# Parse a ZIP-321 payment URI
payments = pyzcash.parse_payment_uri("zcash:tmEZhbWHTpdKMw5it8YDspUXSMGQyFwovpU?amount=42.5")
payments[0].amount_zatoshis  # 4250000000
payments[0].amount_zec       # 42.5

# Generate a ZIP-321 payment URI
pyzcash.create_payment_uri("tmEZhbWHTpdKMw5it8YDspUXSMGQyFwovpU", 4_250_000_000)
# "zcash:tmEZhbWHTpdKMw5it8YDspUXSMGQyFwovpU?amount=42.5"

# Derive a unified address from a seed
import os
result = pyzcash.derive_address(os.urandom(32), network="main", account=0)
result.unified_address  # "u1..."

What it wraps

Function	Crate	Does
parse_address()	zcash_address	Validate + classify addresses
parse_payment_uri()	zip321	Parse ZIP-321 URIs
create_payment_uri()	zip321	Generate ZIP-321 URIs
derive_address()	zcash_keys	Seed to unified address (Orchard + Sapling)

No reimplemented crypto. Checksums, key derivation, encoding are all handled by the Rust libraries.

Status

Alpha. Four functions that work. Next steps:

• Transaction building
• Wallet scanning via zcash_client_backend
• Viewing key import/export
• Pre-built wheels so you don't need Rust installed
