When scanning a wallet QR code using the TenX app, you may receive an error "Invalid QR Code", even if the code works on other apps.
When we rebuilt the app in React Native, we made the decision to only support QR codes following the correct BIP0021 standard (more info can be found here).
The BIP0021 standard says that any wallet address QR codes must be prefixed by their respective blockchain (for example "bitcoin:[address]" or "ethereum:[address]"). We decided to enforce this standard as it highly reduced cases of users sending funds to the wrong blockchain.
Unfortunately, there are a significant number of wallet providers who do not follow the standard, so we have decided to come up with an alternate design solution to try and stop users sending funds to the incorrect blockchain. Once this alternate design solution is ready, we will again open up scanning plain QR code addresses, which will stop this error from occurring.
In the meantime, you will be able to copy and paste the address of the wallet you are trying to send to into the address field in the TenX app.
