# Core Mechanics & Security

* 0% Tax: On-chain transfers and trades of $哈喽 have no transaction fees, ensuring the frictionless circulation of value.

* Renounced Ownership: The contract ownership has been renounced, meaning no one (including the developers) can modify the contract rules, guaranteeing its permanent decentralized nature.

* Security Audit by Salus Audit: The project has been audited by Salus Audit (<https://four-meme.gitbook.io/four.meme/salus-audit-report>).
