ELFI [ELFI (Wormhole)] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Contract name (ELFI Token (Wormhole)) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.
