Designed around the lot

A block doesn’t need
a single buyer.

01

Fund the auction.

Deposit the Stock Tokens you want to sell. Choose a starting price, a minimum price and an auction length.

02

Let buyers take portions.

The price follows its fixed schedule. Each purchase pays USDG to you and transfers the purchased tokens to the buyer in the same transaction.

03

Keep control of the rest.

Cancel the unsold remainder, or reclaim it after expiry. Completed purchases cannot be undone.

Read the risks

Fixed after funding

The asset, price path, seller and expiry are recorded onchain. No admin can edit an active auction.

A maximum cost for buyers

Purchases include an exact token amount, a maximum USDG cost and a deadline. Failed settlement reverts both sides.

Corporate-action protection

A changed token multiplier blocks new fills until the seller cancels and creates new terms. Recovery remains subject to issuer transfer restrictions.

A sale, not a yield promise

Proceeds come from actual buyers. Listing a lot does not create demand or guarantee a complete sale.
