I'm building a web-based Stellar Wallet for the current build challenge.
Here is the TESTNET demo URL: https://testnet.astralwallet.io. The demo doesn't have all feature flags turned on (the federation server, 2FA, email notifications, etc. are not turned on yet).
1. Multiple stellar addresses per wallet
2. Emphasis on security in secret key storage and authentication (2FA, proper email verification, etc.)
3. Federation support
4. Post-build challenge: if I get accepted into the build challenge, I will add support for multiple tokens and explore multiple platforms.
I'd really appreciate feedback in the coming days. I am focusing on finalizing security features and building federation support. Looking forward to your comments.
