CLOUD DATAThe CLOUD hook: a stock pool that knows when Wall Street is open
A Uniswap v4 hook for tokenized-stock pools on Robinhood Chain. Trades that push a pool away from the Chainlink price pay more, especially when the market is closed. Trades that bring it back pay the base fee. 80% of the surcharge goes to liquidity providers, 20% buys and burns $CLOUD. Live on NVDA/USDG since September 7, 2026.
What a trade pays right now
The base fee is 5 bps and every trade pays it to LPs. A trade that leaves the pool further from the reference than it found it also pays a surcharge: 2 × (gap beyond 0.25%) × the session multiplier, capped at 3%. These are live quotes for this session.
Add liquidity
Add liquidity on Uniswap↗
Opens Uniswap's own app with this exact pool pre-filled: USDG / NVDA, v4, the hook, dynamic fee. You connect and sign there, never on this site. Pick a range, deposit, done. Your position is a normal Uniswap v4 NFT that you control and can withdraw any time.
Uniswap's app does not allow persons in the United States to provide liquidity in stock tokens, and shows a region notice instead. That is Uniswap's rule for every stock-token pool, not something this page controls.
The pool is seeded small on purpose. It is a beta: the code is verified but not yet audited. If you provide liquidity to stock tokens, this pool is built for you, and the backtest below is why.
Doing it by hand instead
- In the Uniswap app on Robinhood Chain choose New position, version v4.
- Pick USDG and NVDA (the Robinhood stock token). Open the settings gear and enter the hook address below. The fee tier shows as dynamic; tick spacing is 10.
- Choose a range around the current price and deposit.

How it works
Tokenized stocks trade around the clock; the shares behind them trade six and a half hours a day. Whoever provides liquidity to a stock-token pool is quoting prices all night and all weekend against people who will know the next print before the pool does. On the chain's largest NVDA pool that cost LPs about $163,000 in one week, against $118,000 of fees earned.
The hook reads the Chainlink feed for the stock inside every swap. Chainlink republishes on a 0.5% move, so the pool is free to trade inside a 0.25% band around it. Beyond the band, a trade that widens the gap pays 2 × the excess, times 1× in market hours, 1.25× pre and post market, 1.5× overnight, and 2× on weekends, capped at 3%. A trade that narrows the gap pays only the base fee, so arbitrageurs who fix the price are the cheapest traders in the pool. If the feed goes stale beyond four days the hook falls back to the base fee; it never freezes a pool.

Notes
- Toxic flow is a 10-minute markout against the real NVDA market price (Yahoo 1-minute bars, 24/5). Weekend trades mark to Monday's first pre-market bar. It estimates loss-versus-rebalancing, not realized LP PnL.
- The hook's reference is the real Chainlink RHNVDA/USD feed, which republishes on a 0.5% deviation (67 updates in the window), so the pool legitimately sits inside a band around it.
- The replay keeps flow fixed. A live hook would deter some widening trades and attract narrowing ones, so hook fees here are an upper bound and toxicity a lower bound on the improvement.
- "Widening" means the trade left the pool further from the reference than it found it.
Questions
- Is my liquidity locked?
- No. It is a standard Uniswap v4 position NFT. Withdraw any time from the Uniswap app.
- What does the CLOUD community get?
- 20% of every surcharge accrues in the hook. Anyone can call
collectto send it to the collector wallet, where it is used to buy and burn $CLOUD, as voted by holders. - Can this run on other stock tokens?
- Yes. Any of the 32 stock tokens with a Chainlink feed on Robinhood Chain can be registered on the same hook by anyone. NET is not covered by Chainlink yet.
- Is it audited?
- Not yet. The code is verified and the tests replay real swaps, but treat this as a beta and size accordingly.
