This release fixes it, and those payments are credited once you upgrade. It also runs on PHP 8.1 and 8.2 now, and a standalone install sitting inside a WordPress site&#39;s folder no longer answers 403.<br/><br/>WooCommerce shops can save the BTCPay plugin settings without the key being rejected, and a customer who retries paying an order gets the payment page instead of a 404.<br/><br/>The QR libraries used to load from CDNs, including on the admin page that can show your seed phrase. They ship with the app now.<br/><br/>There&#39;s also a signed emergency shutdown. If we ever find a hole that lets strangers take your money, we can publish a notice signed with a Nostr key, and installs on the affected versions stop until they&#39;re upgraded. Nothing moves your funds. If you&#39;d rather not have it, turning off the update check in Settings turns it off too.<br/><br/>Reasoning for doing this in this blog: <a href="https://juraj.bednar.io/en/blog-en/2026/09/18/ten-ai-models-vs-embargoed-core-lightning-a-case-study-of-ai-for-auditing/">https://juraj.bednar.io/en/blog-en/2026/09/18/ten-ai-models-vs-embargoed-core-lightning-a-case-study-of-ai-for-auditing/</a> (Section &#34;Signed kill switch&#34;).

No node or BTCPay instance; it runs on ordinary PHP shared hosting and settles through a Cashu mint.<br/><br/>Four AI audits went over the server and the wallet library, and this release fixes what they found: fee handling on withdrawals, a double-spend path in exports, an amount-check bug, and an invoice-status check that stopped working after the first try.<br/><br/>Still alpha.

We outsource our payments to &#34;convenient&#34; gateways because we&#39;re afraid of the tech stack.<br/><br/>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.<br/> <br/>Don&#39;t wait for the &#34;official&#34; circular economy. Build it on your own server today. 2026-05-27T16:48:00Z https://njump.me/nevent1qqswjlyrgjpvlmrv3w5awx4q6u4qvqs0fcz23tcpg296daxq6x9cnkqzyq7rq3klgnjqw6l8teylsghwvcews20hxshpdjuccyt9xe8ce6v65tgrpsp If you need a KYC&#39;d third-party gateway to accept Bitcoin, you aren&#39;t using Bitcoin. You&#39;re just using a slower, more expensive version of Stripe. Good for adoption for clients, but if you are a merchant, you&#39;re missing out.<br/><br/>True sovereignty means owning the checkout. CashuPayServer lets you accept Lightning payments directly on your own WordPress site (or anywhere where BTCPay is supported - prestashop, ...) without asking a corporate middleman for permission.<br/><br/>Yes, it runs on your $5/month hosting that you already have. No node/VPS/docker required. Just install as wordpress plugin or unzip (in case of non-wordpress install), configure and you are good to go.<br/><br/><a href="https://cashupayserver.org/">https://cashupayserver.org/</a> 2026-05-15T10:37:00Z https://njump.me/nevent1qqswqrx69ngfu77m5gy0dp9w65y2kt0mlg9hygn8zs93v3nv9r0j9jszyq7rq3klgnjqw6l8teylsghwvcews20hxshpdjuccyt9xe8ce6v65lxga9m Why is it so hard to sell a digital PDF for Bitcoin without using a centralized platform that takes a 10% cut?<br/><br/>CashuPayServer is the missing link for the independent creator. It’s a one-click WordPress/WooCommerce plugin that turns any basic website into a professional Lightning storefront. Keep 100% of your sats. Own 100% of your data. Free and Open Source.<br/><br/>Your shop, your rules. 2026-05-11T11:36:00Z https://njump.me/nevent1qqsq6z2geppcwcf50xxu4h8pn9fhmpwqdpwswynq8ndvzw9fh63q3pczyq7rq3klgnjqw6l8teylsghwvcews20hxshpdjuccyt9xe8ce6v65gdk56h Privacy isn&#39;t just for customers; it&#39;s for merchants too. Why should your payment processor know your turnover, your products, or your customer&#39;s identity?<br/><br/>CashuPayServer uses Cashu mints for settlement of Lightning payments. This creates a &#34;privacy buffer&#34; between your shop and the network. The mint sees the Lightning payment; you see the credit. Nobody sees the link between the two except you.<br/><br/>Why Cashu mint? The easiest way to accept Lightning and not run a Lightning node. And yes, it can immediately withdraw to a real non-custodial Lightning wallet.<br/><br/>Accept Lightning with &#34;Stealth Mode&#34; enabled. 2026-05-04T15:59:00Z https://njump.me/nevent1qqsd7ufquz9y6qzkuw0k6u5ny4se73xw3wt4p8akv50lgkn66xkqmfszyq7rq3klgnjqw6l8teylsghwvcews20hxshpdjuccyt9xe8ce6v65rm9eap In reply to <a href='/nevent1qqsfskyekelktqjx8w0tnzm09q649uuwmcpadx6x2evf6h227x9relcd8q5a4'>nevent1q…q5a4</a><br/>_________________________<br/><br/>Can most shared hostings run C# code?<br/><br/>And which remote ln node?

You need to maintain it.<br/><br/>Their page mentions only VPS for $10+, do you have tips for $2-$5 VPS? Might be useful for other projects. What Lightning node do you use in this low-cost setup?<br/><br/>Anyway - the point of CashuPay is that it can run on what you already have (PHP hosting for your e-shop). You don&#39;t need anything extra, not even $2 VPS. Just unzip and go.<br/><br/>P.S.: I am fan of BTCPay, if it&#39;s not a problem for you, run it, I also run one. This project is for people for whom the more complicated setup is a barrier to accepting Lightning. 2026-05-02T08:23:42Z https://njump.me/nevent1qqsv04tw2r0ts6w6cm4w4gw9lrctvpj6lv5zlry84wuuz8k3a09hqqqzyq7rq3klgnjqw6l8teylsghwvcews20hxshpdjuccyt9xe8ce6v6597wwjt In reply to <a href='/nevent1qqs8weskyefsvk8q8jjce4qv26tadh5uvz0gh458j5ayzt36vvc5hachfg8ud'>nevent1q…g8ud</a><br/>_________________________<br/><br/>I don&#39;t agree. It&#39;s still not running on the cheap PHP hosting. Yes, AI can deploy it, but you still need docker, or a way to run at least the main dot net daemon. Way different than unpacking a zip / installing a WordPress plug-in.<br/><br/>If anyone can run BtcPay, we&#39;re all for it and love the project. Cashupayserver is for those who can&#39;t do it for whatever reason. 2026-04-26T08:14:38Z https://njump.me/nevent1qqsdh4plmzmcgkd0yme8r34c2hsl6q996kqcglk7l528xa0eznss7uczyq7rq3klgnjqw6l8teylsghwvcews20hxshpdjuccyt9xe8ce6v65808p6k Most people think running a private Bitcoin payment server requires a $20/month VPS, Docker, and a sysadmin degree. It doesn&#39;t.<br/><br/>CashuPayServer is a Free and Open Source Lightning payment gateway that runs on standard, cheap PHP hosting. If you can host a WordPress site for $5/month, you can host your own Lightning payment gateway. Simple install. No terminal required. No complexity tax.<br/><br/>You can accept Lightning payments - clients don&#39;t need a Cashu wallet.<br/><br/>Stop overpaying for hosting you don&#39;t need.
