We have started a company designed to safeguard crypto, and have raised over $4.5M from world-class investors like Nascent, Figment Capital, RobotVC, and others. We started in the aftermath of the Nomad hack. We spoke with affected users, DeFi founders, and engineers, uncovering a frightening reality: many can’t sleep for fear of being hacked, and some have even left the space altogether. Our entire industry's credibility has suffered from these daylight robberies, with billions of dollars lost in hacks. This experience marked the true beginning, and our team is on a mission to make top-tier crypto security absolute and accessible. We believe hack prevention must be proactive and impossible to circumvent. We are building the Credible Layer, a step-level improvement for on-chain security, by creating an on-chain protocol and off-chain infrastructure that enables protocols to enforce security rules for every transaction that interacts with them. On top of that, we deeply believe that open-security is net-possitive for the space, building a whole platform so that end-users coalesce on the Credible Layer as the focal point for the security of every ecosystem.
