Web3Modal

There are other several libraries to create a web3 enviroment as: Rainbowkit || Wagmi || Scaffold-eth || useDApp || web3modal || Web3-UI

It seems like a rare solution. There's this library which claims to help but on its demo site it has the same problem as what my code has.

Now lets install Web3Modal library(https://github.com/Web3Modal/web3modal). Web3Modal is an easy-to-use library to help developers add support for multiple providers in their apps with a simple customizable configuration. By default Web3Modal Library supports injected providers like (Metamask, Dapper, Gnosis Safe, Frame, Web3 Browsers, etc), You can also easily configure the library to support Portis, Fortmatic, Squarelink, Torus, Authereum, D'CENT Wallet and Arkane. Open up a terminal pointing atmy-app directory and execute this command

I've used web3modal in the past

The Web3Modal library is a simple Web3/Ethereum provider solution, which enables the addition of support for multiple providers in the application. The Web3Modal library supports the injected providers that we’ll rely on in this project, MetaMask and Tor.us.

I've asked in discord server, and a guy shared me that library : https://github.com/Web3Modal/web3modal

I'm sorry, I just checked and same problem for me. Maybe you should contact the dev? https://github.com/covidpass-org/covidpass

Their code is supposedly open source so you can read their public repo here: https://github.com/covidpass-org/covidpass

Yeah, you'd think so, wouldn't you. Unfortunately, two factors conspire to make that impossible. Firstly, the QR code for the vaccine card is based upon the Smart Health Card standard, which does it's best to generate the smallest payload possible, but it still ends up being ~1.7KB, which is on the large side for a QR code. Secondly, Apple always applies the "medium" error correction level to QR codes on a pass, and only displays them at a fixed size. Both of these combine to make a QR code on the pass that is too small and too dense to be scanned properly (at least by a smartphone when both devices are handheld). More details in this GitHub issue for another service that is trying to achieve this.

I understand your concerns. This is why the code of the web app and the API is publicly available on GitHub for everyone to see how and what data is processed. Please also consider reading the Privacy Policy.

The whole project is openly available on GitHub, so everyone can check how their data is processed. I have no ambitions to make profits of this but there is a donation link on the bottom of the page to cover the server costs :)
