Uniswap (UNI) launches TJAR for onchain fee conversion across apps

Uniswap (UNI) has launched TJAR, an onchain fee-conversion system designed to let applications collect revenue in whatever tokens users pay with and settle those fees in a single asset of their choosing, according to the company’s Oct. 29, 2026 announcement. The framework is intended to reduce the need for custom fee-conversion infrastructure while giving apps a way to direct proceeds to a treasury, bridge or burn address. In Uniswap’s description, an app selects the token it wants to receive, sets a price and chooses a destination.
