Hi! I’m trying to submit my Mini App, but the Submit button doesn’t work. When I click it, nothing happens and the submission is not sent. I don’t see any error message or confirmation either. I’ve tried refreshing the page, using different browsers, and checking my internet connection, but the issue persists.

Please I need help with the logo icon display on Nimiq pay app. I already added my TipWall logo in the fa icon but it’s not displaying on Nimiq pay app. How can I fix this?

Hey there so I saw that in order for my app to be eligible to enter the contest it has to be available on github. My question is if I can post an open source a Client version on my github that uses it's own libraries to connect and communicate with my backend or if It's required for me to fully post my backend source code + the codebase for my sourcecode.

Hi Nimiq team, I ran into this while building my mini app (NimJump: https://nimjump.zetashare.com), and came up with an idea I think makes a lot of sense — wanted to share it with you directly. The problem: I wanted to notify a player when something happens in the app even if they've closed the tab — for example, when someone joins their VS match and a 24-hour play window starts. But mini apps run inside a WebView, and WebViews simply don't support push/Notifications APIs, so there's no way to reach a player who isn't actively in the app. The idea I came up with: Nimiq Pay already shows a notification the instant a payment arrives. So I started sending both players a near-zero NIM amount (0.00001 NIM) with a custom memo like "NimJump: VS match started — 24h to play!" — purely so it triggers your existing "payment received" notification and acts as a message to the player. It's a workaround, but it works, and I think it points to something genuinely useful you could build in properly. My actual request: please consider surfacing the transaction memo directly in that notification. If you do, this stops being a workaround and becomes a real, zero-infrastructure notification channel that any mini app could use to reach players asynchronously — not just mine. I really think this could be a great addition to the Mini Apps framework.

I need to broadcast NIM transactions on testnet from a small backend (treasury → user payouts at settlement). My transport is offline-sign + HTTP JSON-RPC: build & sign the tx offline (TransactionBuilder.newBasic → signTransaction → toHex), then POST sendRawTransaction to a node. This works perfectly against the public mainnet RPC https://rpc.nimiqwatch.com — it returns a tx hash and accepts the tx. The blocker: the testnet equivalent https://rpc.nimiq-testnet.com is returning an nginx 500 (not responding), so I can't broadcast on testnet. Questions: 1. Is there a healthy/official public testnet (Albatross) JSON-RPC endpoint I can point at — or is rpc.nimiq-testnet.com expected to come back up? 2. If not, what's the recommended way for a Mini App backend to broadcast testnet transactions? (I'd prefer not to run a local node — @nimiq/core's Node client throws on worker init / never reaches consensus in plain Node.) 3. Otherwise, is mainnet with tiny real amounts the intended path for testing Mini App money flows? Thanks!
