Users of Staking DAO (SDT) are likely to be using that token for staking. The token appears in the wallet as a blue circle instead of the correct symbol.
Since we recognize SDT but not the xSDT that users hold to represent their stake, we only cover half the use case. This causes issues with cost basis displayed on transactions as well as tax calculations.
To work around this issue, you can create a custom currency to represent xSDT and manually replace the unrecognized token on your transactions. This will allow the correct cost basis to be applied on all transactions with this token.
