FAQ

Questions, answered

When you pay in USDT or USDC, we check the transfer directly on-chain (Ethereum or BSC) — no third-party processor. Paying with bKash works differently: since it isn't an on-chain payment, we confirm those manually over WhatsApp.

Both unlock every module immediately. With the deposit option, the remaining 50% is due before you start module 3 — everything else about your access is identical.

Yes — choose bKash at checkout and you'll be given a WhatsApp number to complete payment and confirm your enrollment directly with us.

No. The Basic module starts from first principles — what a blockchain is, how wallets work — before you write any code in the Intermediate module.

Yes — it's issued on-chain, so anyone can verify it against the blockchain record rather than just trusting a PDF.

You can request a full refund any time before finishing your third class — see the Return Policy in the footer for details.
