Because our students are crypto-native, and BTC gives us global reach without payment processors or chargebacks. An invoice is emailed automatically once the transaction is confirmed on-chain. We plan to accept stablecoins in a future release.

When you complete registration you receive a unique BIP-21 payment URI and a live EUR→BTC rate. You broadcast the transaction from your own wallet. We then poll mempool.space for the txid and mark the payment confirmed as soon as the transaction enters a block.

Exchange rates drift slightly between the time the page loads and the time you broadcast. As long as you are within 1% we consider the payment valid. Larger discrepancies trigger a manual review — contact us with the txid and we will resolve it within one business day.

Programs are self-paced. You retain lifetime access to the material and can complete the capstone at any point.

No. We are intentionally independent. No program is sponsored by a wallet, exchange, or tooling company. This is part of why we only accept crypto payments — to avoid payment-processor conflicts of interest.
