Uniswap Labs, the primary company behind the decentralized cryptocurrency exchange Uniswap, will introduce a fee of 0.15% on trades involving cryptocurrencies like ETH and USDC, beginning on Tuesday. This fee will only apply to transactions made through Uniswap Labs’ user interface.
This fee is separate from Uniswap’s existing “protocol fee,” which is determined by the community’s governance voters. Uniswap Labs is imposing this new fee to ensure a steady source of funding for their operational expenses, as stated in a blog post.
The “interface fee” will affect transactions that involve at least two of the following tokens: ETH, USDC, WETH, USDT, DAI, WBTC, agEUR, GUSD, LUSD, EUROC, or XSGD, as explained in a FAQ.
Fees are charged for certain tokens only when users use Uniswap Labs platforms on the main Ethereum network and some Layer 2 scaling solutions. These fees apply when both the tokens users trading have fees. However, if users swap between stablecoins or convert between ETH and WETH, users won’t have to pay these fees.
However, a Uniswap spokeswoman later clarified that she “just wanted to clarify that both the input and output token need to be on the list for the fee to apply (not just on one end).”
