Sulkta Coop's Python SDK for merchant-side Cardano payments + NFT certificate-of-authenticity minting. Zero-custody by design. Extracted from TradeCraft's services/cardano_*.py (2,400+ lines of production Cardano-mainnet code) and restructured as an installable Python package. Package layout (cardano_checkout/): - addresses.py — lifted verbatim: CIP-1852 HD derivation, pure pycardano - oracles.py — lifted from cardano_price.py: Koios ADA/USD feed w/ 5m cache - monitor.py — lifted verbatim (SQLAlchemy-coupled; v0.2 refactors to Store) - scheduler.py — lifted verbatim (same refactor note) - invoice.py — NEW: framework-agnostic Invoice dataclass + lifecycle enum - store.py — NEW: InvoiceStore Protocol for pluggable persistence - mint.py — NEW: CIP-25 v2 metadata builder (works); tx submission stub for v0.2 - ipfs.py — NEW: kubo HTTP client with primary-pin + mirror-pin pattern - txbuild.py — NEW: v0.2 stub for PyCardano / Ogmios tx construction Design: - Consumers provide xpub + InvoiceStore impl. SDK provides everything else. - IPFS: local kubo for upload + serve, optional mirror pins for archival. Chromaticcraft pattern: Rackham kubo primary, Lucy kubo mirror. - NFT: single native-script policy per merchant studio (CIP-25 v2, not CIP-68 — full wallet coverage, no mutability needed for static certs). Policy skey stays under Sulkta cold-custody (Lucy pattern); signing is an external hand-off like ADAMaps payouts. Tests: pure-module smoke tests pass for invoice, store-protocol, CIP-25 metadata envelope, IPFS client import, txbuild stub module. Address derivation tests ship but require pycardano + will exercise in CI. LICENSE: Apache-2.0 (matches upstream Cardano tooling). Next (v0.2 scope): - Refactor monitor + scheduler around InvoiceStore (drop SQLAlchemy coupling) - Wire mint.mint_nft_cert to PyCardano + local Ogmios on Rackham - txbuild: Ogmios chain-context + cold-signer hand-off shape - chromaticcraft Phase 2 imports the SDK as its first external consumer
