If you have received an airdrop of UNIH tokens, do not attempt to approve or swap them.
There is a malicious airdrop being sent to ETH.RUNE holders that takes advantage of the transferTo method in the ERC20 contract in order to drain RUNE tokens from the user's wallet.
If you have received UNIH tokens in you wallet, do not touch them. Do not approve them for trading in attempt to sell. The attacker will be able to drain the ERC20 RUNE token from your wallet without explicit permission.
