While you sleep.
Hook Catch turns your plan into rules that trade for you. Take profit, stop loss, buy the dip and DCA, for any Pons token or any ETH-paired Uniswap v4 pool on Robinhood Chain.
Sells keep your tokens in your wallet until they fire. Buys use ETH you deposit and can withdraw any time.

How it works
One contract. Open keepers.
Set a rule
Pick a token and its pool, a line and a limit price. Sells need a token approval; buys need ETH deposited in the contract.
The line is crossed
Any keeper can call the contract. The contract itself checks the price on-chain, so nobody can fire a rule early.
It trades
On the Pons curve or the exact Uniswap v4 pool you picked. ETH or tokens go straight to you; the keeper earns 0.30%.
You stay in control
Limits on everything.
Limit price
Every rule has a worst price. A sale never fills below it, a buy never above it. If the market can't meet it, nothing happens.
Allowance and deposit
Sells can only take what you approved. Buys can only spend what you deposited. Withdraw it any time.
Expiry and cancel
Every rule ends on a date you choose. Cancel any rule in one click.
New rule
The Hook Catch contract is being deployed. You can explore the builder; creating rules opens at launch.

$HOOKCATCH
The token works inside the contract.
Three jobs, all enforced by the Hook Catch contract itself.
Lower fees
The protocol fee is 0.20% of each trade. Hold 100K $HOOKCATCH and it's 0.10%. Hold 1M and it's 0%.
More rules
Without the token you can keep 3 rules active. Hold 100K+ for no limit.
Buyback & burn
Every protocol fee goes to a buyback contract that buys $HOOKCATCH and burns it. More rules firing means more burned.

Changelog
What shipped.
v1.0 · Launch Oct 2026
Hook Catch contract with sell and buy rules, app, keeper board, keeper bot, docs.
Hook Catch is a contract on Robinhood Chain that trades for you when the price crosses a line you set. It works with every ETH-paired token launched on Pons (on its bonding curve while it's live, and in its Uniswap v4 pool after it graduates) and with any ETH-paired Uniswap v4 pool on Robinhood Chain, whatever its hook.
Four rules
- Take profit: sell when the price reaches a target.
- Stop loss: sell when the price falls to a floor.
- Buy the dip: buy when the price drops to a line. Several at different lines make a ladder.
- DCA: buy a fixed amount every interval, up to a price ceiling.
Hook Catch never takes custody of tokens you sell: they stay in your wallet until a rule fires. ETH for buys sits in the contract under your address and can be withdrawn any time.
1. You set a rule
A rule names the token, the kind, the amount, a trigger price, a limit price, how many times it can run and when it expires.
2. A keeper calls it
Anyone can call execute(id). The contract reads the live price on-chain and refuses if the line hasn't been crossed, if the rule expired or if it's too early for the next DCA run.
3. It trades
The contract swaps on the Pons curve, or through the Uniswap v4 pool after graduation, and refuses any fill worse than your limit price. ETH from sells and tokens from buys go straight to you. The keeper earns 0.30%.
- Approve the token for the Hook Catch contract. The rule can sell at most the amount per run, and never more than your balance or approval.
- Set the trigger: above the current price for take profit, below it for stop loss.
- Set the limit: the lowest price you accept per token. The app suggests trigger minus your slippage.
Your tokens stay in your wallet until the rule fires. Setting the approval to zero disarms every sell rule at once.
- Deposit ETH into Hook Catch from the app.
- Pick the ETH per buy and how far below the current price to buy.
- For a ladder, choose several steps: the app creates one rule per step.
The limit is the highest price you accept per token; the app suggests trigger plus your slippage. Tokens go straight to your wallet.
A DCA rule buys the same ETH amount every interval, a set number of times. It has a price ceiling: if the price is above it, the run is refused and tried again later. The first run can happen right away.
- Limit price: sells never fill below it, buys never above it.
- Approval and deposit: the contract can only use what you allowed.
- Expiry: every rule stops working at its end time.
- Cancel: any rule, any time, by its owner only.
- Venue check: a Pons curve must belong to the token, come from the Pons factory and be paired with ETH; a v4 pool must exist. Each rule trades only on its own venue.
- Hooks: a v4 pool's hook can change fills. Only pick pools whose hook you trust; your limit price still caps the damage.
Price manipulation
Triggers read the spot price, which a keeper could push within one transaction. That's why the limit price exists: whatever happens to the price, your fill can't be worse than the limit. Keep limits tight on thin tokens.
A keeper watches the rules and executes the ones that are ready, earning 0.30% of each trade.
- Read
rulesCount()andgetRules(from, to)for the list. - Call
canExecute(id): it returns(true, "")when a rule is ready. - Send
execute(id). If someone was faster, your call reverts and you pay only gas.
The open-source keeper bot in keeper/ does exactly this every 20 seconds and skips rules whose fee would not cover the gas. Use a fresh wallet with a little ETH for gas, never your main wallet.
cd keeper && npm install
KEEPER_KEY=0x… HOOKCATCH=<contract> node keeper.mjs
Add DRY_RUN=1 to see what it would execute without sending anything. MIN_PROFIT sets how much the fee must beat the gas (default 1.2×).
Small rules can cost a keeper more gas than they pay. Rules of 0.05 ETH or more are the ones keepers reliably pick up.
keeper fee 0.30% of each trade, to whoever executes it
protocol fee 0.20% → buyback & burn of $HOOKCATCH
0.10% if you hold 100K $HOOKCATCH
0% if you hold 1M $HOOKCATCH
Fees come out of the ETH: from the proceeds of a sale, or from the ETH of a buy.
- Lower protocol fees for holders (0.10% at 100K, 0% at 1M).
- Unlimited active rules for holders of 100K+ (3 without).
- Every protocol fee buys back and burns $HOOKCATCH.
The contract reads your balance when a rule runs or is created. The token address is set once in the contract after launch and can never change.
One contract. The owner can change only the fee destination, and set the token address once. It can't touch rules, deposits or approvals.
Source, tests and the keeper bot are on GitHub.
- Smart contracts can have bugs. Hook Catch is tested on a fork of Robinhood Chain but has not had an independent audit yet. Start small.
- A rule fires only if a keeper calls it. In quiet moments that can take a while.
- The limit price protects every fill, but a fast market can blow past your line and the limit, and then nothing fills.
- Pons tokens are volatile. Nothing here is financial advice.
