I would like to exchange a small amount of LEND Token (87) to ETH.
If this is the token you are talking about (
https://www.worldcoinindex.com/coin/aave ) you will see a list of exchanges trading it.
But beware, at most exchanges you may be under the minimum withdraw amount (I think that at Binance you may be able to withdraw though, but that'll be close to the minimum limit too).
