Severity:
Adding Blacklistable Tokens to Accepted Collateral Assets Can Potentially Cause Loss of Funds for Stakers
Description:
Some tokens, such as USDC, have a blacklist functionality that allows the admin to block certain addresses from transacting with these tokens. Adding such tokens to the accepted collateral assets will result in some stakers being unable to withdraw their rewards because claimReward() fails when called, as the tokens cannot be transferred to them.
Tools Used:
Manual review
Recommended Mitigation Steps:
Caution should be applied in selecting assets to use as collateral for EUROs stablecoin. Generally, it is advisable to avoid blacklistable tokens like USDC.
