If you are looking for a wallet development company?  https://www.ebizneeds.com/blog/digital-wallet-app-development-guide/ It's important to conduct thorough research on each company's background, expertise, and experience to determine which one is the best fit for your project. Additionally, reading reviews and testimonials from past clients can also provide valuable insights into the quality of their work and customer service.

Exploring the fascinating Walt Wallet project!  The innovative approach and insights showcased in this project are truly impressive. For anyone interested in eWallet app development, I found a comprehensive guide at https://www.nimbleappgenie.com/blogs/ewallet-app-development-guide/. Kudos to the team behind Walt Wallet for pushing the boundaries in the digital wallet space!

What's the latest on the project? I'm very interested in what you've come up with. Privacy and security are important in crypto wallets, and it's great to see a focus on off-the-shelf hardware. I've been exploring similar ideas for my own project, using resources like https://dashdevs.com/blog/how-to-create-a-digital-wallet/ for building digital wallets. It's a valuable guide. One practical tip is to consider incorporating multi-signature functionality for added security. This approach can make the wallet even more robust. 

Nice work, when do you think you'll be sharing the build? How do you want help with the project?

Right now, we mostly work from the discord (https://discord.gg/dtAwRBX3hJ) and try to onboard more devs to help/tinker with. 
A first thing we dunno really how to handle is proper code/git management.

We use a micropython base, with a new esp32 board, but also some changes to the esp32 port directory itself.
Do you have experience with micropython custom builds and how to address that in the best way? Are there some known strategies?

In current state, we did release some code in private to a few devs with detailled instructions, but we'd like a proper and future proof code organization so we are not stuck further down the road.

Apart from that, we released a simulator (on the discord atm) running on stock python so you can test drive the gui interface, suggest gui alternatives and extra modules.

Cool stuff! Looking forward to play with it
