Learn crypto by doing — with test coins.
Short lessons, a quiz for each, and a student sandbox on Solana devnet where you launch, burn and manage tokens for free. Nothing here uses real money.
Lessons
A wallet is a pair of keys. The public address is like an account number you can share; the private key (or the recovery phrase that creates it) is the only thing that can move your funds.
Self-custody means nobody — not Bajar, not support staff — can recover or reverse anything for you. Write your phrase on paper and never type it into a website or chat.
Bajar Wallet encrypts your keys on your device and adds a post-quantum (ML-DSA-65) signature for sign-in.
Someone from "support" asks for your recovery phrase to fix your account. What do you do?
Student sandbox
