Uniswap founder Hayden Adams posted on X, saying, "Uniswap Labs and the Uniswap Foundation have never charged any fees for protocol deployments. Uniswap protocol deployments are done through governance voting. For Uniswap's interface, we prioritize based on the required effort and work involved (for example, a new zk chain may require more work than a standard op stack chain). We're investing heavily to reduce the amount of work needed for each chain."
