What Blackpool is

Blackpool 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. Blackpool 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. By default (version 2) it is timelock-encrypted and opened only inside the settlement transaction; if you choose to reveal it yourself, it is public for the short reveal window. The page What the contract guarantees lists exactly what leaks and when.

The shape of one trade

Deposit USDG or a stock into the vault.
During the commit window, post your order with a 1 USDG bond: the hash plus the order encrypted to a drand round (default), or the hash alone if you prefer to reveal it yourself.
After the reveal window, the keeper opens every encrypted order and settles in one transaction. Crossed orders fill at the pool midpoint; the rest goes back to your vault balance. (Self-revealed orders are opened by you during the reveal window.)
Withdraw whenever you like. Balances not locked in an open order are always withdrawable.

Status

Version 2 is live on Robinhood Chain at 0x59e89Ed4D0E126B8260694bF40B16156dA64A6ee, deployed on 29/09/2026 with the nine launch markets and $BPOOL as its staking token. The source is verified on Sourcify (exact match). It adds encrypted orders and a reference price to version 1.1. It has not been audited yet: size your orders accordingly. The protocol keeper samples, opens and settles every batch; its status is public at blackpool-keeper.fly.dev.

Earlier deployments are paused for new orders; anything left on them, including stakes, can still be withdrawn: version 1.1 0xd1F22941F39b4CAABD46BfB66d8c7DB28F4c3b22 (27/09/2026) and version 1 0x7E9443D8A589E5A40f820c87086545D4156d73d8 (26/09/2026).
