Step 2

Verify and download

After wallet confirmation, paste the 52-character transaction ID. The server verifies the payment against a public mainnet indexer.

What is verified

Confirmed mainnet payment, exact receiver, exact 0.21 ALGO amount, valid sender, no close-out, release timestamp, and the secret commitment. The transaction remains independently inspectable on-chain.

Challenge module

The download now includes a disabled-by-default Algorand Mainnet USDC template for ASA 31566704, the required x402-global-challenge tag, an activation validator, a GoPlausible integration example and a requirement-by-requirement checklist. It becomes usable only after the buyer supplies a funded, opted-in address; the kit does not claim registration, settlement, ranking or prize eligibility.
