Overview¶
Sweep launches strategies on Robinhood Chain: tokens whose trading fees buy a collection's floor, relist what they buy, and burn the token with what it sells for.
Every strategy starts on its own bonding curve. When buyers have put 4.2 ETH into it, it graduates into a Uniswap pool, and the machine starts: every trade in the pool pays a 10% fee, and 8 of those 10 points land in the strategy's treasury as ETH. The treasury buys the cheapest pieces of one collection and puts them on its shelf above cost. When a piece sells, the whole sale buys the token back and burns it.
Most launches never graduate, and never sweep. That is the filter: only a token people actually wanted gets a machine. See The curve.
The loop runs on trading. Nobody tops the treasury up and nobody has to remember to run it. Each step is a call anyone can make, and the burn pays whoever makes it.
After graduation, every trade pays 10%. 8 points reach the treasury as ETH.
It buys a piece as soon as a seller meets its bid.
It goes on the shelf at 1.2 times what the machine paid.
What the piece sells for buys the token back and burns it.
- No redemption The token cannot be traded in for a piece, or for ETH from the treasury.
- No claim The pieces belong to the strategy, never to its holders.
- No floor The token can trade below its treasury, and nothing is broken.
Kinds of strategy¶
The curve, the fee and the pool are the same for every strategy. What the treasury buys is not.
Why it exists¶
A collection has no way to turn attention into demand for its floor. Interest arrives, the floor moves, the interest leaves. A strategy gives the collection a bid that grows with trading on its token, and that keeps bidding for as long as the token trades.
The token gets a use for its fees that anyone can check: they buy real pieces, and the pieces end as burnt supply.

A block arrives about every 100 ms, 119 times faster than on Ethereum. Anything paced by counting blocks would run 119 times faster than its author meant, so everything in Sweep that moves over time follows the clock instead.
