What Blacksite is

Blacksite is a venue for trading tokenised stocks on Robinhood Chain without publishing your order first. It is one contract. It keeps a vault of USDG and stock balances, collects sealed orders in batches, and crosses buyers against sellers at the midpoint of the stock's Uniswap V4 pool.

It is called a dark pool because that is what the thing does in equity markets: orders are not displayed, they meet each other at a reference price taken from the lit market, and size that does not meet stays with its owner.

What it is not

• Not an AMM. Blacksite has no liquidity curve and no LPs. If nobody is on the other side of your order in the same batch, nothing fills.
• Not a router. It never swaps on Uniswap. It only reads the pool's price, the same slot0 a swap would move.
• Not private end to end. An order is sealed while the batch takes orders, then opened for a short reveal window before it settles. The page What the contract guarantees lists exactly what leaks and when.

The shape of one trade

1. Deposit USDG or a stock into the vault.
2. During the commit window, post the hash of your order with a 1 USDG bond.
3. During the reveal window, open the order. The contract checks it against the hash and locks the size.
4. After the window closes, anyone calls settle. Crossed orders fill at the pool midpoint; the rest goes back to your vault balance.
5. Withdraw whenever you like. Balances not locked in an open order are always withdrawable.

Status

Version 1.1 is live on Robinhood Chain at 0xd1F22941F39b4CAABD46BfB66d8c7DB28F4c3b22, deployed on 27/09/2026 with the nine launch markets. It replaces the first deployment (0x7E9443D8A589E5A40f820c87086545D4156d73d8, 26/09/2026), whose staking accumulator rounded small fees away against a large stake; that contract is paused for new orders, traded nothing, and any stake on it can be withdrawn at any time. If you used it, connect the same wallet in the app: it lists what you left there, with a button to unstake, claim or withdraw each part. The source is verified on Sourcify (exact match). It has not been audited yet: size your orders accordingly. The protocol keeper settles every batch that has orders and pokes a market while it has revealed orders; its live status is on the Contact page.
