Use Cases

Use Gitcoin Passport scores to verify that an address represents a unique human, reducing the risk of sybil attacks in airdrops or governance.
Display ENS names and social profiles to provide a more human-readable identity for wallet addresses in your application.
Check POAP holdings to verify attendance at events or membership in communities.
