Full Changelog: v0.2.0...v0.3.0

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.

Changed

• cdk(wallet): wallet:receive will not claim proofs from a mint other then 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]).
• cdk(wallet): Additional arguments in send send_kind and include_fees for control of how to handle fees in a send ([thesimplekid]).
• cdk(wallet): Additional arguments in create_swap include_fees for control of if fees to redeam the send proofs are included in send amount ([thesimplekid]).

Added

• cdk: TokenV4 CBOR ([davidcaseria]/[thesimplekid]).
• cdk(wallet): wallet::receive_proof functions to claim specific proofs instead of encoded token ([thesimplekid]).
• cdk-cli: Flag on send to print v3 token, default is v4 ([thesimplekid]).
• cdk: MintLightning trait ([thesimplekid]).
• cdk-mintd: Mint binary ([thesimplekid]).
• cdk-cln: cln backend for mint ([thesimplekid]).
• cdk-axum: Mint axum server ([thesimplekid]).
• cdk: NUT06 MintInfo and NUTs builder ([thesimplekid]).
• cdk: NUT00 PreMintSecret added Keyset id ([thesimplekid]).
• cdk: NUT02 Support fees ([thesimplekid]).
