According to CoinMeta, Wu said that Uniswap has announced the launch of an on-chain fee conversion framework Tjar ( Token Jar ), which allows third-party applications to automatically convert fees charged in different tokens into specified tokens without the need to build their own conversion infrastructure. This framework was initially used for handling fees on the Uniswap protocol and completed over $15.3 million in asset conversions last month. It is now deployed on 7 blockchains. Uniswap stated that Robinhood has adopted Tjar through Uniswap API on the chains it supports, converting the fees collected into USDC and USDG.
