Receipts for saleSandbox

Each row is title to one sealed item held by a bonded Keeper. Buy it and the receipt moves to your wallet in the same transaction as your test USDC moves to the seller. The box never moves. Prices sit next to the index reference so you can see the spread.

Nothing offered right now. Owners list receipts from the hold page; the sandbox simulator lists one every so often.

Any Ethereum wallet works and the sandbox costs nothing. On a phone, open this page inside the wallet app. On a computer, install a browser wallet, then reload.

How a purchase works

Approve the Settlement contract to spend the price in test USDC, then fill the signed offer. The contract checks the seller still owns the receipt, that it is held, moves the USDC to the seller and the receipt to you. The prepaid custody fees travel with the receipt. If anything fails, nothing moves.
