Frequently Asked Questions
Get clear answers about our specialized service for building compliant, high-performance sanctions oracles on the Cosmos ecosystem.
A sanctions oracle is an on-chain service that provides real-time, verifiable data on sanctioned addresses or transactions. Your Cosmos app needs one to ensure regulatory compliance for DeFi protocols, cross-chain bridges, or NFT marketplaces, preventing interactions with blacklisted entities. Our CosmWasm-based oracles integrate directly with your smart contracts, enabling automated, trust-minimized compliance checks without sacrificing performance.
