Every LP and lending tool Poolfish offered now runs on Metrix. If you are arriving from there, this post covers what waits for you, how to move over, and what happens to Poolfish Pro.

I also want to tell you why this one is personal. Most acquisitions are spreadsheet decisions. This one is closer to a homecoming, and I have the commit history to prove it.

I was a Uniswap.fish user before any of this

In 2022 I started providing liquidity on Uniswap v3, and the ranges humbled me fast. Concentrated liquidity had turned LP returns into something you could engineer, and it made the math hard enough that guessing got expensive. The tool LPs sent each other back then was Uniswap.fish, built by an independent developer named Chun Rapeepat on a Uniswap Foundation grant. You gave it a pool, a range, and a deposit, and it told you what the position might earn. Over its history, more than a million liquidity providers have trusted that tool. In 2022 I became one of them, running my ranges through it before I committed a dollar.

Here is the part of the story fewer people know. When I founded what became Metrix in August 2023, the first version was called BuildrMetrics, and it was a fork of the Uniswap.fish open source repo. We rebuilt everything from the ground up after that, and BuildrMetrics became Metrix Finance. So Metrix and Poolfish are not strangers. They are branches of the same tree.

The middle of the story belongs to Noah Bragg. In 2023 he bought Uniswap.fish for $37,000, told the internet exactly what he paid, renamed it Poolfish, and built it in public for three years. Four exchanges, a pool discovery page, a weekly newsletter, and Poolfish Pro all came from Noah. The full history, receipts included, is on the Poolfish story page.

So when the chance came to acquire Poolfish, the decision took about a minute. The tool that taught me LP math, the one Metrix literally descends from, was looking for its next steward. It went home with one of its own users.

Bring the whole workflow over

We want your whole workflow, and we built Metrix to deserve it.

Everything Poolfish did has a home on Metrix, and your old Poolfish calculator links now open the same pool on Metrix with the range already filled in. That covers continuity. The case for moving everything else is what Poolfish never had:

• Coverage of 19 exchanges across 12 networks, including Uniswap v4, Aerodrome, Velodrome, and Solana DEXes like Orca and Raydium

• Backtesting on real pool history, with impermanent loss included in the results

• Position tracking across wallets, with closed positions, transaction history, and price alerts

• Lending markets on Aave, Compound, and HyperLend across 17 chains

• Exposure and hedging analytics, plus price correlation for choosing ranges

• Metrix AI, a research copilot inside the app

• A Market page for the macro read, with news beside it

• A full-time team shipping regular releases

The sections below walk through the big ones.

Finding pools got a much bigger map

Poolfish covered four exchanges. Discover on Metrix covers 19, across 12 networks, including Uniswap v3 and v4, Aerodrome, Velodrome, Orca, and Raydium. If you LP on Base or Solana, those pools sit in the same table as your mainnet ones.

Pro members can filter by any metric, filter by token, set the calculation window behind the APR and volume numbers, and choose which columns show. When something looks worth a closer look, one click opens it in Simulate.

From estimates to backtests

The original fish answered one question well: given current pool numbers, what might this range earn? Simulate on Metrix starts from that same question and goes a lot further. Projections are built from the pool’s real history, so you can set a range, pick a timeframe, choose the calculation method that fits the pool, and see what the position would have earned, with impermanent loss in the result. The liquidity distribution shows how your range sits against the rest of the pool, down to per-tick asset composition, and you can snap the range to real ticks so the math matches the pool exactly.

Then you can stress the position before it exists. Model a future price and a number of days to see how it behaves as the market moves, and run the comparison against simply holding, so you know whether providing liquidity is worth it at all. Metrix saves your simulations, so last week’s research is waiting when you are ready to act. Elite members also get the composition view, which models several positions together as one portfolio. An estimate opens the conversation. A backtest settles it.

Tracking does the bookkeeping now

Poolfish showed you your positions. Metrix keeps the books. Add a wallet address in Portfolio, Metrix indexes it, and every LP and lending position shows up in Track with live value, fees earned, and performance against holding. Closed positions keep their full history, so you can judge a strategy end to end after you pull liquidity. Price alerts tell you when price leaves your range, instead of you finding out days later.

If you run size across several wallets, Elite is built for that: ten wallets with wallet groups, twelve alerts, exposure breakdowns across the whole portfolio, price correlation between assets when you choose a range, and unlimited history.

Lending sits next to your pools

Lending was never a Poolfish feature. On Metrix, supply and borrow rates for Aave, Compound, and HyperLend across 17 chains run through the same Discover, Simulate, and Track flow as pools. Sometimes the honest answer to “which pool should I enter?” is “none this week, lend it instead.” Now you can check that without leaving the app.

Metrix AI, for the questions in between

Pro members get Metrix AI, a copilot that works inside the same app, on the same data. Ask it to find pools that fit what you want, explain what a lending market is doing, or sanity-check a strategy in plain language, at whatever hour the question hits you. We wrote about it in the v4.1.2 release post.

How to get set up

1. Create a free account at app.metrix.finance. Free includes one wallet, open positions, and browsing every pool and lending market.

2. Keep using your old links if you like. Saved or shared Poolfish calculator links open the same pool on Metrix with the range filled in, and the pool tables on poolfish.xyz stay up, fed by Metrix data.

3. Add your wallet in Portfolio. Metrix indexes it and your positions appear in Track. New wallets can take a short time to index.

4. Rebuild your watchlist in Discover and run your usual pools through Simulate.

5. Set price alerts. Concentrated positions stop earning when price leaves the range, and the alert is how you hear about it early.

If you pay for Poolfish Pro

You do not need to do anything. Your subscription moves to Metrix Pro, and you keep paying your current Poolfish rate. We will email you the details before anything changes on your billing. Poolfish Pro is no longer sold to new customers.

Where Pro and Elite fit

Free is a real tier, and it is the right place to start. Metrix Pro, at $50 a month or $500 a year, is where the analysis lives: the full Discover filters, advanced simulation, closed positions, performance charts, alerts, three wallets, and Metrix AI. Metrix Elite, at $800 a year, is for LPs managing several wallets and real size, with exposure and hedging analytics, price correlation, the composition view for modeling a whole portfolio, twelve alerts, ten wallets, and unlimited history.

Both come with a 7-day free trial, so put your own positions in and judge Metrix on your own numbers before you pay. Start your free trial.

Where Noah goes next

Noah documented Poolfish from the day he bought it, and the habit did not stop with the sale. His next project is a trading account started with $250, published trade by trade, wins and losses alike, on YouTube and X. If you followed Poolfish for the build-in-public side, that is where the story continues. Follow along.

Let the fish keep swimming

Chun built the original with community money. Noah bought it, said the price out loud, and carried it for three years in public. Now it lives with a team whose founder learned LP math running ranges through the original, at a company that started as a fork of its code. Three stewards, one tool, and the same job from start to finish: telling LPs the truth about what a position will earn.

Thank you, Chun. Thank you, Noah. And if you are arriving from Poolfish, welcome home. We have been getting the place ready for three years.
