Why Work with Us


We are a tight-nit team of blockchain industry veterans solving one of the largest problems facing the mass adoption of crypto: transaction security.

We are scanning millions of transactions each week for malware and scams and are helping keep their users safe. Transaction security is a high leverage way to make a difference in the world โ€” protecting users funds and enabling them to give informed consent when entering digital agreements involving their finances and other ownership rights. We support EVM and Solana blockchains and will be adding more chains soon.
