Accept Bitcoin without the complexity Payment gateways want your ID. BTCPay Server needs a VPS and Docker expertise. CashuPayServer is the middle ground: a BTCPay-compatible gateway that runs on the PHP hosting you already have.
CashuPayServer v0.4.1-alpha ⚡ Accept Lightning on the PHP hosting you already have. This release is about not losing track of a single sat: Recover funds from a previous mint — if a mint change ever stranded a balance, scan and export it back as a claimable token Changing a store's mint now warns and offers export instead of silently stranding funds New "Recent Transfers" ledger on the dashboard: every Lightning withdrawal, auto-withdrawal, token export and donation, in one place Upgrading never touches your ecash — the DB is separate and migrates itself. Still alpha; start small, keep your seed safe.
cashu-wallet-php v0.1.0 — first tagged release 🥜 A single-file, zero-dependency PHP implementation of Cashu. Drop CashuWallet.php into any PHP 8 project and go. Covers NUT-00/01/02/03/04/05/07/08/09/12/13/19/20 — including keyset v2, NUT-13 HMAC derivation, DLEQ verification, and NUT-20 BIP340 quote locking. Crash-safe operation journal, so you don't lose coins mid-swap or mid-melt. 284 tests, validated against the official Cashu spec vectors. Still very alpha, feedback appreciated.
CashuPayServer v0.3-alpha has some security and reliability fixes. Give it a try and definitely upgrade if you are using the older version.
The biggest threat to the circular economy isn't regulation, but laziness. We outsource our payments to "convenient" gateways because we're afraid of the tech stack. CashuPayServer was built to kill that fear. It’s a lightweight, PHP-based Lightning gateway that settles via Cashu. It’s as easy to install as a contact form and as private as a cash transaction. Don't wait for the "official" circular economy. Build it on your own server today.
