During her time at Uniswap, Lader worked on building systems for finance, legal matters, hiring, marketing, policy, and customer service. Her efforts helped Uniswap shift from a project run mainly by developers to a more organized company.

Lader confirmed her departure in a July 16 post on X, "After four incredible years as President & COO of Uniswap, I’m starting something new. I'm excited to scale from here. Stay tuned".

Uniswap, founded by Hayden Adams in 2018, operates on Ethereum ETH $3,264.38 and allows users to trade tokens directly with one another. It does not act as a middleman like centralized exchanges (CEXs), but instead, it uses smart contracts to make token swaps between users possible.

The company has not yet announced who will take over Lader’s role, but it has stated that it plans to continue building on her work.
