Uniswap Labs today released TJAR, permissionless infrastructure that converts an app’s onchain fees into a single token. Robinhood is the first integration partner, with more coming soon.
Today, apps that charge a fee are paid in whatever tokens their user’s trade. Over time, that adds up to thousands of different tokens, across every chain they support. Typically, consolidating these holdings into a few chosen tokens has meant building custom conversion infrastructure.
TJAR replaces that infrastructure with an open market. Apps deposit their fees into a Token Jar. Searchers compete to convert them, and the app automatically receives fees in its chosen token.
The Token Jar framework was first built for Uniswap Protocol fees. In September, Token Jar handled more than $15.3M in conversions. TJAR lets any team use the same system for its own fees.
TJAR is now live on seven chains. Documentation, deployment addresses, and guides are available on the Uniswap Developer Platform.
