# Audits & Security

## **Security**

Squid's smart contracts are designed to never hold liquidity, they only orchestrate calls to DEXs, and any other involved contracts. They do this, and deal with edge cases around cross-chain mechanics. This avoids security risks usually associated with token bridges.

Squid's TEEs are also undergoing constant monitoring.

## Audits

**To date, Squid has undergone 9 audits.** Squid emphasizes the security of its platform and the safety of users' assets. Regular audits are conducted to ensure the integrity and security of Squid’s smart contracts and protocols.

* 6 audits by [Ackee Blockchain](https://ackee.xyz/)
* 1 by [Consensys Diligence](https://consensys.io/diligence/)
* 1 Audit by [0xKaden](https://twitter.com/0xkaden?lang=en)
* 1 Audit by [n-Var](https://github.com/0xsquid/audits/blob/main/audits/2024-09%20n-var.pdf)

We conduct ongoing audits that review all changes to the code to ensure a high degree of security.
