Marketplaces need both name screening (for sellers) and wallet screening (for crypto payments). SanctionsAI covers both with a single API. For KYC-bundled solutions, SumSub and ComplyAdvantage offer marketplace-specific packages.

Risk vector	Description	Mitigation
Seller from sanctioned jurisdiction	Seller located in or operating from Iran, North Korea, Syria, Cuba, Crimea	Geographic screening at registration
Seller is SDN-listed	Individual or entity on OFAC SDN list	Name screening at onboarding
Buyer payment from sanctioned wallet	Crypto payment from OFAC-designated wallet address	Wallet screening for crypto payments
Shipping to sanctioned jurisdiction	Physical goods shipped to comprehensively sanctioned countries	Address screening at checkout
Payment to sanctioned bank	Seller payout routed through designated financial institution	Bank screening at payout configuration

For AI agents on marketplaces: Agents that facilitate marketplace transactions should screen both the buyer and seller side. A seller in a sanctioned jurisdiction receiving payments through a proxy is a common evasion pattern.
