# Security

Sandclock takes security seriously. Every contract deployed to mainnet has been independently audited. Lindy Labs also runs formal verification to catch issues that traditional audits miss — see [Aegis](https://lindylabs.net/articles/introducing-aegis).

## SOC 2 Report

Lindy Labs is SOC 2 Type 1 compliant, covering the systems and controls that underpin Sandclock. Independent attestation reports are available below.

## Smart Contract Audits

All deployed contracts have been reviewed by independent security firms. Reports are organized by component.

### ERC4626 Vault

The core vault contracts were audited twice ahead of the v2 launch.
