Cashu-TS v4.3.0 just released! This release tightens spec compliance and hardens wallets against real-world mint quirks: BOLT12 quotes, NUT-12 DLEQ verification, and nullable wire fields now behave correctly across mint implementations. Slow Lightning payments can now be fire-and-forget: wallets can save the in-flight payment, restart or hand off to another process, and still reclaim their change once the payment settles thanks to new OutputData serializers and wallet.createMeltChangeProofs method. New developer ergonomics include a CTSError base class for cleaner error handling and a maxSpendableAfterFees primitive that makes "send max" flows trivial to build.

A little sneak-peak of what's to come in Cashu... the amazingly talented @thesimplekid has been working on building ONCHAIN mint/melt in CDK mint. And today, I got Cashu-TS ready to support it... here's a demo on an onchain mint/melt 👇

Cashu-TS v4.2.0 is now available. This version continues to strengthen the security of the library, updating our core Noble crypto deps to the latest version, adding stronger mint url validation, and fixing a bug that could cause CORS failures in clients using Firefox/Webkit and older CDK mints.

It even has an agent migration skill to make upgrading apps from v3 to v4 easier.

Cashu-TS v3.6.1 released today - this is a minor patch to ensure token refresh when using authenticated mints. It also fixes a problem with authentication and keysets v2.

Cashu-TS V3.6.0 released today. This version adds NUT-19 (Cached Retry) support, an experimental SIG_ALL signing package module, and two step minting (prepare then complete) to give apps finer control. It also lays some important groundwork for v4, so will likely be our last v3 branch release as we start the sprint to v4.

First world problems, I know... but I do find it quite stressful to see this going down so fast. 🤖🦞

Cashu for WooCommerce v0.1.1 now released. This version adds order details to the LN invoice (when supported by your provider) and adjusts fee calculation and display. It also fixes a checkout total mismatch and improves recovery error handling during token payments. Sorry, it's a manual update at the moment - upload the plugin and overwrite the old one when prompted.

Agent commerce and transactions are easy if you use ecash. 🦞✌️ Here’s a demo; ask your OpenClaw to request a fortune from Clawtar. It will learn the skill of 402 payments, and you get a novelty fortune reading.

My OpenClaw agent, Arthur, wanted to encode and decode Cashu emojis, so he built a skill. It also lets agents hide arbitrary text in emojis. Get it here:
