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.

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.

@LAPOSSCRYPT X changed everything about X premium, it now takes several weeks to verify.

We're are waiting for it.

And we were the first ones on Robinhood to build on it !

What you get:
- the best route across every Uniswap pool and every Uniswap Aggregator Hook pool on Robinhood Chain, in one HTTP call or one MCP tool
- your own fee, up to 0.5%, paid on-chain to your address in the same transaction as each swap you route
- a spot on the Built on Hookline showcase, and an announcement from us on X
- a builder key with higher limits, and a dashboard with your swaps, volume and fees earned

Docs, OpenAPI spec, llms.txt for your AI coding assistant, a copy-paste TypeScript starter and the MCP server are ready.

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.

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.

Why we show you every route we checked.

A swap app that only shows one number asks you to trust it. Hookline shows its work instead: the full list of candidate routes for your trade, ranked by what each would give you alone, with the ones it picked highlighted.

You can see when a Slipstream pool reached through an Aggregator Hook beats every Uniswap pool, when a two-hop path through USDG beats the direct pool, and when the split across several routes pays more than any single one.

If the router is right, you will see why. If a route looks wrong, you will see that too.

Building a bot, an agent or a wallet on Robinhood Chain? Hookline's engine is an open API.

One call: GET /api/quote with sell, buy, amount and your address. You get the best route across every Uniswap and Aggregator Hook pool, the split, the minimum received, every route checked, and the approval steps your wallet still needs.

Second call: POST /api/swap with the quote id. You get the Universal Router transaction, already simulated on the live chain, ready to sign and send from your own key.

No SDK, no account, no custody. Rate limited by default, higher limits with a key on request.

Buying a Pons token with size?

A 2 ETH buy of PONS right now gets checked against 69 routes across Uniswap and Aggregator Hook pools, then split 60/40 between a route that ends in a Slipstream pool via a hook and a direct Uniswap v3 pool. Price impact: 0.29%. Network cost: about 2 cents.

Big buys stop draining one pool. Small buys simply go to the best one.

Same for BUN, DELTA, HMM and every listed token.

Hookline's hook explorer: a live map of Uniswap's Aggregator Hooks on Robinhood Chain.

It reads both Slipstream aggregator hooks directly on-chain, lists every pool they wrap (102 today), and shows for each one: the pair, the outside liquidity behind it, its 24h volume and swaps, and the Uniswap protocol fee it charges.

It also indexes every swap that goes through a hook, from any app, not just Hookline: 128 swaps and about $25k in the last 24 hours, and about $23 of protocol fees already sent toward the UNI burn since launch.

Find where the depth is, then swap that pair in one click.

Four layers between you and a bad swap on Hookline:

1. Pinned contracts. Every Uniswap contract, hook and pool is checked against its known code before a single quote. If one ever changes, it is taken out of routing, or swaps pause.

2. Simulation. Your exact transaction is run against the live chain from your address before you sign.

3. On-chain minimum. The amount you receive is protected by the router itself: below your slippage, the whole swap reverts.

4. Browser checks. Your browser refuses to forward anything that does not target the Uniswap Universal Router on Robinhood Chain with the exact amount you typed, and any Permit2 request must be short-lived and capped to your trade.

No custody, no deposit, no new contract to trust.

What Hookline does in the second after you type an amount:

1. Candidate routes. Every direct pool and every two-hop path through ETH or USDG, across Uniswap v3, Uniswap v4 and Aggregator Hook pools. For a PONS trade that is 69 routes over 25 pools.

2. Quoting. All of them priced at once with Uniswap's own quoter contracts, batched into a few calls. Hook pools are simulated through the hook itself, so the outside price is exact.

3. Splitting. The order is cut into 10% slices and each slice goes where it moves the price least, across up to 4 routes that share no pool. An extra route is only kept if it pays for its own gas.

4. Checking. The final split is quoted again exactly, then your whole transaction is simulated on the live chain.

You see the result, every route checked, and how it compares with Uniswap pools alone.

The simplest way to think about Aggregator Hooks: an adapter.

Slipstream pools on Robinhood Chain speak their own language. Uniswap v4 speaks another. An Aggregator Hook is the adapter in between: plug a Slipstream pool into it and Uniswap sees a v4 pool.

Uniswap shipped two of these adapters on Robinhood Chain, and together they already wrap 102 pools and about $7.4M of liquidity. Every swap through them pays a Uniswap protocol fee toward the UNI burn.

An adapter is only useful if something plugs into it. That is Hookline: a router that reads every adapted pool and every native Uniswap pool, prices them all for your trade, and settles the best mix in one transaction.

A full Hookline swap in one minute.

Pick a pair, type an amount, watch every route get checked, Uniswap pools and Aggregator Hook pools side by side, then see your order split across the best ones.

One signature, from your own wallet.

We built it. The first swap engine for Uniswap v4 aggregator.

Uniswap v4 is now an aggregator

Aggregator Hooks wrap external liquidity sources and turn them into Uniswap pools

Live today on Ethereum, Base, and Robinhood Chain in the Uniswap Web App and API

[HookLine @hooklinetrade]

Today Uniswap v4 became an aggregator.

Aggregator Hooks plug outside pools (Slipstream on Robinhood Chain) straight into Uniswap v4.

Most apps will use a few of them. We built a swap that checks every single one, next to every Uniswap pool.

Launching soon.

[HookLine @hooklinetrade]

Uniswap just turned outside liquidity into Uniswap v4 pools with Aggregator Hooks.

On Robinhood Chain, that is 100+ new pools any router can trade through.

We built the router that uses all of them at once, and splits your trade across them.

Soon.
