Hookline is live on Robinhood Chain.
It is a swap that checks every pool before you trade: Uniswap's new Aggregator Hooks plug in. Then it splits your order for the best price.

Filled by the market. Held by you.
That is the whole design of Hookline limit orders, and it is what makes them different.
Many on-chain limit orders lean on someone else: a keeper bot to execute them, a server to store them, a contract
to hold your tokens. Ours need none of that. Your order is a native Uniswap position at your exact price, owned by
your wallet, and the market fills it simply by trading through it.
Nothing to trust but Uniswap. Nothing to pay Hookline. Nobody can touch it but you.
Place yours in the Limit tab:
hookline.trade/swap
Limit orders are here. On Hookline. On Robinhood Chain.
This is our biggest update since launch, and it changes how you trade. No more staring at the chart, waiting for
your price, refreshing at 3am. Set your price once and let the market come to you.
Pick a pair. Type your price. Sign. Your order goes straight into the Uniswap pool itself, and the moment a trade
crosses your price, it fills. Day or night, with or without you.
Zero Hookline fee. No keeper, no bot, no custody. And while it fills, your order earns the pool's trading fee.
Once it fills, withdraw in one click.
Set your first order:
hookline.trade/swap
Every route checked. No favourites, not even the hooks.
Live quote, 1 ETH to CASHCAT: Hookline built 35 routes across 18 pools, 24 of them through Uniswap Aggregator
Hooks, and priced each one for exactly 1 ETH.
The winner was a plain Uniswap v3 pool, 100% of the order. The best route through a hook gave 0.37% less, so it
was not taken.
That is the job: pay you the most, whichever pool it is.
hookline.trade/swap
No more "apply and wait" to build on Hookline.
API keys are now instant and free. Name it, copy it, go. Your key lifts your limit to 300 quote and build calls a
minute, and with a payout address you can add your own fee on every swap, up to 0.5%, paid on-chain to you in the
same transaction.
The showcase is still there for projects that want to be featured.
hookline.trade/build
Outside liquidity now pays Uniswap.
Every swap through an Aggregator Hook pool pays a Uniswap protocol fee, 0.10% of the swap on Robinhood Chain today. The hook sends it to the token jar that feeds the UNI burn.
So when a router like Hookline fills part of your trade from a Slipstream pool, Uniswap still earns on it. That is the deal Aggregator Hooks make: outside pools get Uniswap's order flow, Uniswap gets a fee.
Since launch, about $24 of protocol fees have already flowed from Robinhood Chain hooks. You can watch it live on the Hookline explorer.
hookline.trade/hooks
Why Robinhood Chain is a great place for an aggregator.
Blocks every 0.1 seconds, swaps that cost a few cents, and now, thanks to Uniswap's Aggregator Hooks, outside liquidity reachable from Uniswap itself.
Cheap gas means splitting a trade across several pools pays off even at medium sizes. Fast blocks mean your quote is still fresh when your swap lands. Hookline is built to take advantage of both.
hookline.trade
Introducing Proof of Savings.
Every swap on Hookline now comes with a public, on-chain verifiable proof of what it saved you.
How it works: when you get a quote, Hookline also computes the best route using Uniswap pools alone, split included, the result a Uniswap router without Aggregator Hooks would give you. When your swap confirms, we compare what you actually received, after our fee, with that baseline. The difference is your saving. If it is zero, the proof says so.
Each proof has its own page with the route, the block and the transaction link, and a one-click share to X.
Example from a live quote: 200,000 PONS to ETH, 0.036 ETH more than Uniswap pools alone after our fee, +0.17%.
hookline.trade
Hold HOOKLINE. Swap free.
Starting today, any wallet holding 1,000,000 HOOKLINE pays no Hookline fee. Every swap, any pair, any size.
Nothing to stake, nothing to claim, nothing to sign up for. Ask for a price with your wallet connected and the fee line reads "Free".
Same best route across every pool on Robinhood Chain, just without the 0.15%.
hookline.trade/swap
This is what we built it for !
Happy to see AMLIL plugging Hookline routing straight into their router. Better fills for every AMLIL user, private swaps one tick away.
AMLIL is now built on @hooklinetrade .
Hookline is the swap aggregator of Robinhood Chain: every Uniswap v4 pool, every Aggregator Hook pool, every venue it maps, quoted and split in one transaction through the Universal Router. We plugged it straight into our router.
What changes for you:
Better fills. Every AMLIL route now carries Hookline's aggregated quote next to our own candidates. When the split beats the single best pool, you see it, and you swap it.
Private swaps. Tick Private and the swap settles to a fresh wallet, with nothing on-chain linking it to the sender. Hookline plus Houdini under the hood.
Same AMLIL. Every hook indexed, Aggregator Hooks detected by behaviour, compute jobs signed by the node, every call paid with x402 in USDG.
The first privacy-capable Uniswap v4 aggregator swap engine on Robinhood Chain, and it is live.

Here is the path your trade takes in Hookline's new Private tab.
Stage 1, best price: your swap is split across the Uniswap and Aggregator Hook pools that pay most, in one transaction.
Stage 2, private: Houdini Swap carries the result through two separate exchanges and a privacy hop to the fresh wallet you chose.
Two stages, one card, no on-chain link at the end.
hookline.trade/swap
Best price. Now private.
The biggest Hookline update yet is live.
Swap at the best price on Robinhood Chain, then send what you received to a fresh wallet with no on-chain link between the two.
- swap at the best price across every Uniswap and Aggregator Hook pool
- open the Private tab and hit "Swap and send privately"
- the tokens arrive on a fresh wallet, with no on-chain link back to you
And if a send cannot complete, Houdini refunds it to your wallet.
hookline.trade/private
What you are signing when Hookline asks for a Permit2 signature.
A message that says: the Uniswap Universal Router may take up to this amount of this token from my wallet, until this time. That is it.
The amount is capped to your trade, the expiry is 30 minutes, and the spender is Uniswap's router, never a Hookline contract. Hookline checks the signature server-side before building the swap, and your browser checks the message before asking your wallet.
The approval to Permit2 itself happens once per token, the standard Uniswap way.
hookline.trade
Price impact, measured honestly.
Many swaps estimate impact from pool math. Hookline measures it: it also quotes a tiny slice of your trade, one thousandth of the amount, on every route. That gives the best marginal price available right now.
Your price impact is how far your actual rate falls below that marginal price. Pool fees are already inside both quotes, so impact is only the cost of your size, nothing else.
Above 3% you get a warning. Above 20% Hookline refuses the trade and suggests a smaller amount.
hookline.trade
Sometimes the best road has a stop.
Selling 200,000 PONS for ETH just now: the best direct pool gave 20.46 ETH. Going PONS to USDG first, then USDG to ETH, gave 20.98 ETH, about 2.5% more.
Selling PONS for ETH does not have to go straight from PONS to ETH. Hookline also tries two-step routes: PONS to USDG first, then USDG to ETH, each step in whichever pool is deepest.
That matters now because some of the deepest PONS liquidity sits in Slipstream pools paired with USDG, reachable through Uniswap's Aggregator Hooks, while ETH to USDG is deepest on Uniswap v3.
Hookline prices both kinds of routes for your exact amount and takes the best, all in one transaction.
hookline.trade
Same trade. More with hooks.
Every Hookline quote runs the full search twice: once with every pool, once with Uniswap pools only. The difference is what Uniswap's Aggregator Hooks add to your trade, and it is printed under the quote.
Right now, selling 200,000 PONS for ETH: the best route goes through a Slipstream pool via an Aggregator Hook, then Uniswap v3, and returns 0.67% more ETH than the best route with Uniswap pools alone.
On big orders, that is real money. On small ones, Hookline simply takes the best pool, hook or not.
hookline.trade

How much do Aggregator Hooks actually add? Hookline measures it on every quote.
The router computes the best route with every pool on Robinhood Chain, and the best route with native Uniswap pools only. If the hooks help, you see "+X more than Uniswap pools alone" next to your quote, in tokens and in percent.
Today it ranges from nothing on pairs where Uniswap is deepest, to around half a percent on large PONS trades where Slipstream holds deep liquidity.
No marketing number: the real gap for your trade, right now.
