Changelog

[Unreleased]

0.12.0

Summary

Version 0.12.0 delivers end-to-end BOLT12 offers and payments, adds BIP‑353 address resolution for BOLT12 payments, and introduces cdk-ldk-node, an integrated Lightning backend that lets a single binary run both a Cashu mint and a Lightning node with full BOLT11 and BOLT12 support. It also adds a local, admin-focused web UI for cdk-ldk-node with dashboards for channels, invoices and offers, payments, and on-chain activity. On the data layer, the release expands storage with PostgreSQL via the new cdk-postgres crate and accelerates the shared SQL stack (cdk-sql-common) with statement caching and structured, namespaced/global migrations. Operationally, the mint now exposes explicit start and stop lifecycle methods, enabling graceful startup and shutdown of background services. Wallet keyset management has been clarified with renamed APIs that separate local storage from network fetches—making load_mint_keysets the primary entry point for token operations—and the MSRV is updated to 1.85.0.

0.11.0

Summary

Version 0.11.0 brings significant architectural changes to enhance database reliability and performance. The major changes include:

1. Database Engine Change: Replaced sqlx with rusqlite as the SQLite database driver and removed support for redb. This change provides better performance and reliability for database operations.

2. Transaction Management: Introduced robust database transaction support that encapsulates all database changes. The new Transaction trait implements a rollback operation on Drop unless explicitly committed, ensuring data integrity.

3. Race Condition Prevention: Added READ-and-lock operations to securely read and lock records from the database for exclusive access, preventing race conditions in concurrent operations.

⚠️ Important Migration Note for redb Users

If you are currently running a mint with redb, you must migrate to SQLite before upgrading to v0.11. Follow these steps:

1. Stop your current mint
2. Back up your database
3. Use the migration script available at: https://github.com/cashubtc/cdk/blob/main/misc/convert_redb_to_sqlite.sh
4. Update your config file to target the SQLite database engine
5. Start your mint with v0.11

v0.2.0

Summary

This release introduces TokenV4, which uses CBOR encoding as the default token format. It also includes fee support for both wallet and mint operations.

When sending, the sender can choose to include the necessary fee to ensure that the receiver can redeem the full sent amount. If this is not done, the receiver will be responsible for the fee.

Additionally, this release introduces a Mint binary cdk-mintd that uses the cdk-axum crate as a web server to create a full Cashu mint. When paired with a Lightning backend, currently implemented as Core Lightning, it is included in this release as cdk-cln.

• cdk(wallet): wallet:receive will not claim proofs from a mint other than the wallet's mint (thesimplekid).
• cdk(NUT00): Token is changed from a struct to enum of either TokenV4 or Tokenv3 (thesimplekid).
• cdk(NUT00): Rename MintProofs to TokenV3Token (thesimplekid).

Added

• cdk: TokenV4 CBOR (davidcaseria/thesimplekid).
• cdk(wallet): wallet::receive_proof functions to claim specific proofs instead of encoded token (thesimplekid).
