Decentralized exchange Uniswap (UNI) will begin charging a 0.15% swap fee on certain tokens in its web application and wallet on October 17.
According to a post by Hayden Adams, the DEX’s founder, the affected tokens are Ethereum (ETH), USD Coin (USDC), Wrapped Ether (WETH), Tether (USDT), DAI, Wrapped Bitcoin (WBTC), Angle Protocol (agEUR), Femini Dollar (GUSD), Liquidity USD (LUSD), Euro Coin (EUROC), and StraitsX (XSGD).
The interface fees will be deducted from the output token amount. In addition, fees will not be collected on swaps between Ether and Wrapped Ether trading pairs, nor on inter-stablecoin swaps.

I work in crypto because of the immense positive impact I believe it can have on the world, removing gatekeepers and increasing access to value and ownership.

I’m proud of the ways @Uniswap Labs has contributed to that effort and want to make sure we’re creating sustainable…
