Cross-Chain API

Query compliance data across any AVALANCHE® network from your backend

Building on a custom AVALANCHE® L1? You can still check if a user is KUMPLY-verified on any other network. Our SDK handles all the cross-chain messaging for you.

No need to understand Interchain Messaging internals. Just call our SDK functions and get a yes/no answer: is this user compliant? What tier are they? When does it expire?
