CDK Release
Version 0.13.0 marks a major milestone for mobile development with the introduction of comprehensive native mobile bindings that enable building Cashu wallets for iOS and Android using Swift and Kotlin. The release introduces cdk-ffi, a new Foreign Function Interface crate that provides UniFFI-based bindings for Swift and Kotlin, with full wallet functionality including multi-mint support, BOLT12 payments, BIP-353 address resolution, and advanced features like P2PK conditions and authentication. Mobile bindings are distributed through dedicated repositories at https://github.com/cashubtc/cdk-kotlin and https://github.com/cashubtc/cdk-swift that provide native package management for Android/JVM and iOS/macOS platforms respectively. The release also delivers significant infrastructure improvements including an event-driven payment architecture with real-time notifications, enhanced database layer with generic key-value storage, improved HTTP transport with proxy support and BIP-353 DNS resolution, and new operational features like Prometheus metrics collection and dedicated authentication database support.
Full release notes: https://github.com/cashubtc/cdk/releases/tag/v0.13.0
Thanks to @nprofile…n7a8 for much of the work on the bindings

cdk and mintd Version 0.12.0
https://github.com/cashubtc/cdk/releases/tag/v0.12.0
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. The MSRV is updated to 1.85.0.

CDK v0.10.0 released
Introduces the new SignatoryManager service, a significant architectural enhancement that provides complete segregation between the mint and its most sensitive component: the private keys. The SignatoryManager offers a clean API for all key-related operations and keyset management, with communication limited to messages passed through the manager interface, ensuring the signatory remains isolated from the rest of the mint. This foundation enables future deployment of signing operations in separate services or foreign environments to reduce operational risks. Additional improvements include a new mint URL flag option, enhanced NUT-04/NUT-05 implementations, ARM64 Docker support, and updated dependencies.

If the api was expanded settings could be stored client side and included in the api request still pay with ecash and avoid the need for accounts.
Of course settings could be used to fingerprint depending on how specific or uncommon your specific set of settings is. So some loss of privacy.

2024-11-21 22:47:15 UTC

- reply

Yeah its just a really simple wrapper around their api. The benefit is no account so more private. Trade off is you can't do customization per account since there is no account.

2024-11-21 22:31:17 UTC

Just pay with ecash no need for an account.

What are you considering spent? When the proof is sent from one person to the other. Or when the receiver actually claims it from the mint.

2024-08-13 17:51:52 UTC

- reply

Are only the proofs stored on nostr not quotes etc?
And it's just the one replaceable event so each time a transaction is made that event is replaced removing spent proofs and adding new unspent proofs?

The amount and the mint are in the token. Is the idea behind putting them in the tags so that clients don't have to parse tokens? If so how is posting an amount tag of 1000 but a token worth something else handled?

2024-06-14 19:01:56 UTC

- reply

Ah nice didn't realize there was an integrated cashu wallet.
Is there any sort of arbitration or once you pay you're trusting the seller?
One way I can think to do this with cashu is P2PK locked tokens. 2/3 seller, buyer and a mediator. If there is no dispute seller and buyer can sign without a 3rd party. If there is a dispute mediator sides with seller or buyer.
fyi could be of interest: https://github.com/cashubtc/nuts/pull/124

Maybe, but with an SDK wouldn't every client you want to zap from then be required to support greenlight instead of just NWC? Well guess you could have a second app that handles the greenlight stuff and gives a NWC uri.

I think snort is using the get_balance rpc drafted in the alby repo which I haven't implemented so a zero balance would be expected. Have you tried zapping anyone to if that goes through?
