Uniswap Labs, the developer firm behind the Uniswap protocol, has seen its cumulative front-end fees cross the $50 million mark.

In October, the platform enacted a 0.15% fee for user transactions on its web interface and wallet app. The accrued fees are directed to the labs, which marked a revenue stream for the firm. In mid-April, Uniswap Labs hiked this fee on its interface from 0.15% to 0.25%.

The cumulative fees have increased over thirteenfold year-to-date, rising from $3.7 million on Jan. 1 to above $50.6 million now.

This comes as Uniswap remains the largest DEX when it comes to on-chain swap volume. Out of the total $154 billion in swap volume during the month, the platform hosted $54 billion, according to The Block’s data dashboard.

Users who want to avoid the front-end fee can utilize DEX aggregators such as 1inch, Cowswap, and Paraswap — though it is worth noting that these platforms may offer different fee models.

In July, the Uniswap front accounted for 25.7% of DEX activity, compared to 19.8% for 1 inch, the most-used DEX aggregator. This is measured in terms of the monthly share of activity generated by DEX frontends.
