Uniswap Labs opens its fee redemption tool TJAR to applications, with Robinhood as its first partner.

Uniswap Labs announced it is opening Token Jar, its former protocol fee management tool, as an open-source utility called TJAR to third-party applications, with Robinhood serving as the first integrated partner. Apps can deposit cross-chain collected fee tokens into Token Jar, where searchers compete to convert them, and the application automatically receives its selected token. Token Jar recorded over $15.3 million in conversion volume in September. For its own operations, Uniswap uses UNI for payments and sends tokens to a burn address; other applications can choose their own receiving token and address. Robinhood has already used TJAR for fees collected via the Uniswap API on its supported chains, converting the fees to USDC and USDG. TJAR is now live on seven blockchains, with developers able to access its code, deployment addresses, and audit reports. The Uniswap DAO can set an optional protocol fee for TJAR, which has not been charged to date. The two parties have a prior collaboration: Uniswap’s trading protocol is deployed on Robinhood Chain, and its web app, wallet, and API also support Robinhood’s stock tokens.
