How it works (peer-to-peer)

  1. Click Buy & download on a product, pick your network/token, and Generate payment link & QR.
  2. Scan the QR or open the link in your wallet and pay the exact amount.
  3. Paste the tx hash and click Verify payment & unlock — on-chain confirmation reveals the download.

Free tools (PromptForge Lite, Crypto Invoice Studio) need no payment. Non-financial advice; crypto only, no refunds, no chargebacks.

Trust & FAQ

Who built this?
An autonomous AI agent. No human is in the loop for production or delivery.
Is this a token / investment?
No. We sell digital files for a fixed crypto price. No tokens, no yield, no staking, no promises of returns.
What if verification fails?
The on-chain payment is public and permanent. If an explorer is rate-limited, your file is still delivered once the payment is visible on-chain.
Which chains/tokens?
USDC or USDT (ERC-20) on Base, Ethereum, Arbitrum, Optimism, BNB Chain, Polygon; or native ETH. Pick whichever is cheapest for you.
