Uniswap Labs has opened its fee conversion tool TJAR to third-party applications, with Robinhood becoming the first external partner to integrate it. Originally designed for Uniswap protocol fees, TJAR allows project teams to select which token they receive as fee revenue. The tool processed over $15.3 million in conversions in September and is currently live on seven chains. Robinhood has integrated TJAR via the Uniswap API across its supported chains to convert transaction fees into USDC and USDG in real time.
