Overpay?
Nope.
Tokenized stocks trade 24/7. The stock market doesn't. In the gap, thin books drift far from fair value — and every wallet lets you click buy anyway. SlipNope is a Uniswap v4 hook that reads Chainlink fair value inside your swap and reverts the trade if you'd overpay beyond the band.
The dislocation tape
Every Coinbase stock token on Base, priced two ways: Chainlink fair (the number the hook enforces) against the market quote. Where they diverge, a buyer is about to overpay — and the guard would refuse the trade.
Fair = Chainlink tokenized-equity feed, read onchain every sweep (total return, multiplier included). Market = Cambrian's Uniswap v3 quote on Base. Premium beyond ±3% is exactly what SlipNope refuses to let you pay. A frozen fair feed fails closed, not open.
The guard is the pool.
Every swap in a SlipNope pool is checked against Chainlink fair value inside the transaction. Outside your band, the swap cannot execute — no warning to ignore, no app to close.
Reading pool + Chainlink…
Connect a wallet on Base to trade under the guard.
A block isn't a dead end. Park the order.
The hook refuses to let you overpay. Say what you will pay — anyone can fill it when the book returns, and you can withdraw any time.
One band. Everyone protected.
SlipNope enforces a universal ±3.00% guard band against Chainlink fair value — no staking, no tiers to buy your way into. The same three outcomes apply to every wallet:
Why a single band: Base Chainlink equity feeds run 24/5 and freeze off-hours by design. A frozen feed is treated as stale and blocks every swap — the guard never guesses at a price. Connect a wallet and the guard card shows your live verdict before you sign, from the same math the hook enforces. Connect to see your verdict.
No attempts yet. Your fills and your blocks will be recorded here — the blocks are the point. Stored locally in your browser.
The guard is one-time-configured and immutable: the Chainlink feed for a pool can never be swapped after setup, there are no admin keys that can weaken a live pool, and a frozen or stale oracle blocks every swap rather than guessing. Coinbase tokenized stocks are available only outside the US per issuer restrictions — nothing here is financial advice, and this product is not affiliated with or endorsed by Coinbase, Base, Uniswap, or Chainlink.
