Uniswap Labs is developing a new hook for Uniswap v4 that would reward liquidity providers on eligible stablecoin pools with OUSD, the dollar-pegged stablecoin issued by Open Standard. The move signals a deepening push by Uniswap into programmable liquidity incentives at a time when competition for stablecoin trading volume across decentralised exchanges is intensifying.
Hooks are an extensible architecture in Uniswap v4 that allow custom logic to run during pool events such as trades and changes to liquidity positions. Traditionally, liquidity providers on Uniswap have earned yield primarily through trading fees generated by their positions. The new hook changes that model by embedding reward distribution directly inside the pool's own mechanics.
The OUSD rewards hook would use that system to deliver Open Standard incentives to liquidity providers in qualifying pools, with the distribution logic living inside the pool mechanics rather than relying on a separate rewards programme layered on top.The initiative is aimed mainly at trading pairs involving stablecoins.
Uniswap Labs is building the integration in collaboration with Open Standard to streamline incentive distribution directly within the protocol.The project remains in early planning, and Uniswap Labs has not disclosed a specific rollout date for the OUSD rewards mechanism. Which pools will qualify has also not been announced.
The timing of the hook exploration coincides with the launch of OUSD itself. OUSD is issued by Bridge, the stablecoin infrastructure firm Stripe owns, with reserves held at BlackRock, Lead Bank and BNY.Coinbase, Mastercard, Shopify, Stripe and Visa have invested as the company's first five founding partners, each receiving an equal initial equity stake, and together the group has committed more than $1 billion to help establish OUSD liquidity.
The token runs natively on Ethereum, Solana, Base and Tempo, and will first be available to trade on Coinbase, Kraken and Uniswap.OUSD always mints and redeems 1:1 against the dollar, with zero fees regardless of size. Rather than the issuer retaining reserve yield, Open Standard inverts the established stablecoin model: partners earn rewards proportional to the supply and activity they drive on their platforms, and can earn equity in the company.
The OUSD hook is not the only recent development on the stablecoin front for Uniswap. It follows the launch of the StablePair Hook in September 2026, which brought dynamic fees to stablecoin transactions on Uniswap v4.
