The coin WEYU incurs a 4% transaction tax in its tokenomics: WeYu - WEYU - YourCryptoLibrary
WEYU resides on the BEP20 and SOLANA chains (at least).
It is very puzzling that this tax is removed when one transacts but apparently does not appear in the transaction records on the block explorer and hence is also missing from imports into Koinly. On at least one of my transactions it is also not exactly 4% that is taken. I guess I can include it manually but the situation is not very satisfactory.
Would be interested if someone could chase up the WEYU team and get this clarified.
