On Thursday, the Uniswap team announced via X that StablePair Hook is now live on Uniswap. It is a Uniswap v4 dynamic-fee hook for stable pairs, launching with two pools on Ethereum mainnet: USDC/USDG and USDC/USDT.
StablePair Hook gives traders consistent, predictable quotes on every swap, and LPs a bigger share of the value they create.
A stable pair trades around a known rate. When the price drifts, there's value in bringing it back to parity. A static fee hands most of that to arbitrage bots. Set the fee low and they keep the spread. Set it high and the pool prices itself out.
StablePair Hook replaces the static fee with a dynamic one. On every swap, it measures how far the pool has drifted from its true rate, or reference price, and sets the fee to match.
-
Inside a tight band around the rate, the fee adjusts under every swap to quote a fixed bid/ask spread
-
Once the price drifts outside that band, swaps that push the price further off pay no fee. They hand the pool a good price to begin with
-
Swaps correcting it from outside the band go through a Dutch auction. The fee starts high, then drops each block until someone takes it. LPs keep the difference
StablePair Hook is designed to evolve over time and with usage. Pool parameters and fee logic can be upgraded through Uniswap Governance, so the mechanism improves without pools needing to migrate.
Uniswap is a decentralized exchange protocol built on Ethereum. To be more precise, it is an automated liquidity protocol. No order book or centralized party is required to make trades.
Uniswap is a popular decentralized trading protocol, known for its role in facilitating automated trading of decentralized finance (DeFi) tokens.
An example of an automated market maker (AMM), Uniswap launched in November 2018, but has gained considerable popularity this year thanks to the DeFi phenomenon and associated surge in token trading.
Uniswap aims to keep token trading automated and completely open to anyone who holds tokens, while improving the efficiency of trading versus that on traditional exchanges.
Uniswap creates more efficiency by solving liquidity issues with automated solutions, avoiding the problems that plagued the first decentralized exchanges.
UNI, the native token of Uniswap, is currently trading at $6.09, down 1.6% in the last 24 hours.
