Uniswap opened its Token Jar (TJAR) fee converter to other apps on Oct. 29, allowing outside traders to acquire accumulated fee assets for a fixed payment. Uniswap said Robinhood already uses TJAR for Uniswap API fees across supported chains and receives USDC and USDG. Only fast searchers capture the available arbitrage profit, although TJAR does not guarantee a profit. Uniswap's Oct. 30 explanation says lower release thresholds generally speed up conversion, but large deposits can create a surplus that benefits searchers at the operator's expense.
