How to build a Crypto Wallet
summary
Builds a working Algorand wallet prototype that generates a 25-word seed from a 1,000-word list, verifies it by asking for 5 random words, and issues a fungible token for a client. Backend uses Django + Python random for seed generation; UI is basic and login is email-based rather than pure on‑chain address authentication. Notes Algorand as carbon-negative, claims combinatorics make brute force infeasible, and the send/demo UI sometimes breaks due to a missing JSON.
