SWEEP DOCUMENTATION

How the market works.

Sweep is an independent application on Robinhood Chain. Sellers deposit supported Stock Tokens in fixed ask offers. Buyers deposit USDG in buy orders with a maximum ask. Any address can execute a compatible fill before either side expires or closes. A fill can use only part of a seller's offer and only part of a buyer's budget.

Supported assets

Initial contract deployment supports the canonical AAPL and NVDA Stock Tokens and USDG on Robinhood Chain. Always verify token addresses on the official token contract page. Stock Tokens are tokenized debt securities providing economic exposure, not underlying shares or shareholder rights.

Accounting

An offer's ask is the USDG amount for one whole 18-decimal Stock Token. Buyer maximum ask limits the offer ask, not a market or oracle price. For each fill, seller proceeds are the filled quantity times the ask, rounded up to one micro-USDG. The executor receives 0.2% of seller proceeds, rounded up to one micro-USDG. Both amounts come from the buyer's deposited USDG. The contract rejects a fill that exceeds the remaining budget.

The executor may select any compatible offer, including a more expensive offer below the buyer's maximum. The contract does not guarantee the cheapest price or automatic matching. A fill occurs only after someone sends a transaction. The interface sorts recent offers only for display and cannot promise execution.

Withdrawals and expiry

Sellers may close an offer and retrieve remaining Stock Tokens. Buyers may close an order and retrieve remaining USDG. An expired record cannot be filled, but its owner can still close it and withdraw. Orders and offers last at most 30 days.

Before using real assets

This contract has local automated tests but no independent security audit. Token transfers may be restricted by issuer rules or jurisdiction. There is no price oracle, automatic fair value check, or guarantee of offers, fills or liquidity. Confirm contract and token addresses in your wallet. Use only amounts you can afford to put at risk.
