# Audits #### Smart Contract Audits At Zyfi, ensuring as much security as possible for our users stands at the core of our mission. \ \ Highlighting our dedication to security, Zyfi's smart contracts are designed to be immutable, significantly enhancing their appeal for several critical reasons: * Audits conducted on these smart contracts remain perpetually valid, as the contracts are unchangeable and cannot be upgraded * Users are relieved from the need to monitor for contract alterations that could potentially lead to fund losses or other nefarious consequences * Such design choice eliminates any possibility for malicious actors to alter the code, or for external pressures (or attacks) to compel a developer to implement unfavourable updates, safeguarding against both cyber and physical threats The integrity of our smart contracts has been rigorously tested both internally and through audits.
