Current Web3 Security is Failing

Just as the eCommerce revolution was powered by new payment security services Blockchain and Web3 cannot fulfil its potential without vastly improving security practices.

Smart Contract Audits, Bug Bounties, and Monitoring systems are not stopping billions of dollars of assets being stolen every year.

Hacks need to be prevented in real-time by Dapps. Being alerted or relying on customer wallet simulations is not enough to prevent Dapps from a catastrophic loss of assets and reputation.
