Poolfish (Prev Uniswap.fish): $8K a month, self-reported in 2023

Poolfish provides calculators and analytics for Uniswap v3 liquidity positions, pools, yields, impermanent loss, and DeFi lending rates. Its $8K a month was founder-reported on the Indie Hackers product page (not independently verified), as of August 2023.

What it actually sells

Poolfish sells calculators and analytics for Uniswap v3 liquidity positions, pools, yields, impermanent loss, and DeFi lending rates. Its tools calculate fee returns, APY, APR, ROI, yields, and impermanent loss based on the pool liquidity a user provides.

The product simulates Uniswap v3 positions and fees, explores liquidity pools across exchanges and networks, backtests concentrated liquidity strategies against historical pool data, tracks LP profit and loss across wallets, and compares DeFi lending supply and borrow rates. Its site says, "Make smarter crypto investing decisions with our V3 calculators and pool data."

How it charges

Where customers come from

The site includes FAQ content about liquidity and pools, including the question, "What is a liquidity provider?" It also includes a weekly LP newsletter.

The site directs users to the Metrix app, stating that every path leads over to the official Metrix app.

What stands out

Poolfish is trusted by more than 1 million liquidity providers. Its pool data covers 19 exchanges across 12 networks, including Uniswap v3 and v4, Aerodrome, Orca, Raydium, and more.

The site describes Poolfish as a community-led tool that has been passed hand to hand for five years. Poolfish began as Uniswap.fish, was built with support from a Uniswap Foundation grant, and later joined Metrix Finance.

Where it sits in the data

Poolfish (Prev Uniswap.fish)'s $8K a month is higher than 64% of the 6,604 projects with founder-reported monthly revenue in our dataset; the median across them is $2K. Snapshot: 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

In my view, a version of this product would need a clearly defined buyer among liquidity providers and crypto investors researching DeFi pool opportunities. Distribution would have to come through search, educational content, community channels, or partnerships with relevant platforms.

The difficult parts are keeping financial calculations accurate, supporting multiple exchanges and networks, maintaining historical data, and handling questions from users working with financial positions. The product also operates in a competitive analytics and calculator category, so a narrow audience and a clear product focus would matter.

Verdict: Needs real work.

One thing to take from it

The product combines position simulation, pool data, historical backtesting, wallet tracking, and lending-rate comparison for liquidity providers. Its site says Metrix lets users test concentrated liquidity strategies against real pool history.
