Moving to Solana

Blackpool shipped on Robinhood Chain as the first dark pool for tokenised stocks: sealed orders, encrypted until the batch closes, crossed at the Uniswap V4 midpoint. A verified contract with no proxy, nine markets, a keeper, an Android app, a mobile web app, and 80 % of matching fees streamed to stakers.

It works. Building it showed us how small the box was.

Why we are moving

A dark pool is only worth the flow it hides. On Robinhood Chain, Blackpool could only ever trade nine stocks against one quote asset. Anything outside those nine tickers, we could not touch. We did not want to stay limited to that.

Solana is the opposite. Tokenised stocks already trade there, next to the majors and the coins people actually trade. It is also where front-running hurts the most: anyone who swaps size on Solana knows sandwich bots. Market makers there already quote in the dark. Traders still cannot. That is the gap Blackpool was built for.

So we are widening the scope: not only a dark pool for tokenised stocks, a dark pool for what people trade onchain. Stocks stay. Everything else gets added.

What carries over

The rules, not the code:

• Orders stay sealed until the batch closes.
• Every crossed order in a batch fills at one price.
• The lighter side fills in full, the heavier side pro rata, the rest goes back to its owner.
• Every division rounds in favour of the venue, so it never owes more than it holds.
• No admin key over user balances.

What gets rebuilt

Solana is not the EVM, so the engine is a rewrite, not a port: the program, the price source for each market, the way orders are sealed, the keeper that settles batches, and the app with Solana wallets. We will give a date for the engine once we have one.

The token

$BPOOL moves first. The contract address is posted on @BlackPoolRH and nowhere else. Anything you see before that post, or from another account, is fake.

If you hold on Robinhood Chain

Nothing is frozen. The v2 contract 0x59e89Ed4D0E126B8260694bF40B16156dA64A6ee has no proxy and the owner cannot touch balances. From Robinhood Chain funds, at any time:

1. Connect the wallet you used on Blackpool.
2. Vault: withdraw your USDG and stock balances.
3. Stake: claim your rewards to the vault, unstake your $BPOOL, then withdraw.
4. Previous contracts: if you staked or deposited on v1 or v1.1, the same page finds those positions and lets you withdraw them.

The site no longer opens new orders on Robinhood Chain. What the contract guarantees still holds, word for word.
