If you participated in the 2nd season of the EtherFI airdrop and you ended up with a small $ETHFI allocation, you can apply to receive an extra 150 $ETHFI tokens by filling up a short anti-Sybil survey on the EtherFI airdrop claim page.
However, timeliness is of essence as you need to complete this process before July 12th and it is only obtainable by the first 30,000 eligible applicants.
