I am I'm testing my mini app but unfortunately I can't log in to nimiq pay. When I click login, the app doesn't respond at all. It really makes it difficult for me to test my mini app. I've tried using another device but the device only displays a white blank when opening Nimiq Pay. Has anyone experienced the same problem?

Hi nimiq team, I can't withdraw usdt from the nimiq wallet on Polygon chain. It gives an error. Would appreciate your help in fixing this.

Hey everyone Me and my teammates was running into a TESTNET issue while testing our Mini App with Nimiq Pay 2.19.1 and wanted to check if this is known or if there’s a workaround. The flow works correctly up to the native transaction approval screen. We approve the transaction in Nimiq Pay, but immediately afterwards we get: “Something went wrong syncing your account.” We reproduced it twice. What I’ve verified: - Nimiq Pay version: 2.19.1 - TESTNET - provider initializes correctly - listAccounts() works - isConsensusEstablished() → true - getBlockNumber() works - transaction amount: 1 NIM / 100000 Luna - requested fee: 0 - recipient is valid - transaction data is 49 UTF-8 bytes, under the 64-byte limit - sendBasicTransactionWithData() reaches the native Nimiq Pay approval UI - after approval, no transaction hash is returned - independent TESTNET explorer check confirms the transaction was never broadcast I also saw another report where even a plain TESTNET wallet-to-wallet transaction on Nimiq Pay 2.19.1 appears to fail after approval, so I’m wondering if this could be a current TESTNET submission issue rather than Mini App-specific. Has anyone found: - a known fix or workaround? - a specific parameter required for TESTNET transactions? - whether validityStartHeight should currently be passed explicitly? - whether this is a known Nimiq Pay 2.19.1 / TESTNET regression? Happy to provide sanitized logs or help reproduce it. I’m avoiding MAINNET testing for now because I don’t want to use real funds just to diagnose a TESTNET issue.

Hi! I have a question regarding the Nimiq Pay / NIM integration requirement. NimiCurl is a multiplayer curling game fully integrated into Nimiq Pay. It uses the Nimiq Pay Mini Apps SDK for wallet connection and uses the connected wallet to power player profiles, identicons, match history and League features. However, the game currently does not use NIM or USDT for gameplay or player transactions. NIM payments are planned for the Partnership area, where sponsors will be able to pay in NIM to support competitions and in-game events. But playing Nimcurl is FREE today ! Would this satisfy the Nimiq Pay / NIM integration requirement, or does the Mini App need to support an actual NIM or USDT transaction to qualify? Thanks!

I have a concern about how the competition’s source-code requirements are presented. The Ownership section on the official rules page states: “Builders retain ownership of their Mini App, code, and intellectual property but release the App and code under the MIT License.” Although developers retain ownership, MIT allows anyone—including Nimiq—to copy, modify, and commercially distribute the code without paying the original developer royalties, provided the required copyright and license notices are preserved. This also applies to submissions that receive no prize. That requirement is easy to miss. You have to visit a separate rules page to see it, while the submission flow starts by asking you to connect your GitHub account. Could the public-source and MIT-license requirements be displayed prominently at the start of that flow, before connecting GitHub? I understand the goal of growing an open-source ecosystem, but retaining ownership doesn’t mean retaining exclusive commercial rights. Participants should clearly understand that they are publishing commercially reusable software in exchange for a chance at winning. Could the team clarify how Nimiq intends to use submitted projects, including non-winning entries, and whether it plans to incorporate or commercialize any of that code? Also, what exact permissions does connecting GitHub grant? Does it only verify our identity, or can it access repositories or make changes? Access to unrelated private projects should not be necessary to enter.
