TJAR: Onchain Fee Conversion for Any App

TJAR is a new framework allowing apps to receive fees in a single token of their choice, with searchers competing to convert accumulated fees from multiple tokens.

Robinhood is already using TJAR to convert fees collected through the Uniswap API into USDC and USDG.
