Integration Patterns
Gated function (most common)
Mint, deposit, transfer restricted to KYC_VERIFIED users
1 Solidity modifier · 5 min
Tiered access
Retail: no KYC. Accredited borrows: require ACCREDITED_INVESTOR proof
2 Solidity functions · 30 min
Jurisdiction gating
Pool accepts users from HK, SG, or AE — doesn't learn which
Use JurisdictionSetVerifier library · 1 hour
Sybil-resistant airdrop
One claim per identity per round via action-scoped nullifiers
Fork KYCGatedAirdrop · 1 hour
Reputation-weighted
Voting power based on credential count, score threshold required
Use CredentialReputation · 2 hours
Time-bounded access
KYC credential expires after 1 year, must re-verify
Use CredentialExpiry · 30 min
