Cyvers

Cyvers sells threat interception to exchanges, custodians, stablecoin issuers and payment firms, in four layers: pre-signature transaction simulation, independent co-signing for multisig and MPC wallets, runtime monitoring, and anti-money-laundering and sanctions screening.

Every pending transaction is simulated to expose its full on-chain effect, and address poisoning, malicious approvals or sanctioned counterparties block it; the monitoring layer models cross-chain fund flows as a graph to spot permission changes, flash-loan attacks and bridge anomalies, then pauses contracts or blocks withdrawals through preset playbooks. Policies are configured by label and limit, and the API embeds into wallet and withdrawal flows at sub-100-millisecond response. All four layers share one address label store, with hits logged for later tracing, and deployment runs in the cloud or on customer hardware.
