# Audit Reports As a blockchain-based exchange project, our primary concern is the security of smart contracts. To ensure the safety of our smart contracts, our development team has written over a thousand test cases, rigorously testing each function and every line of the contract, achieving 100% code coverage. Starting from July 2023, we introduced a testnet of our product, and over 30,000 traders completed more than 100,000 transactions on the platform. Through extensive and large-scale testing, our smart contracts have proven to be resilient, with no significant vulnerabilities found in the testnet. On the other hand, in August and November of 2023, we invited the teams from Halborn and Damocles respectively to conduct meticulous and comprehensive audits of our contracts. Based on the audit results, the teams made the necessary modifications to enhance the security of our smart contracts. {% file src="/files/cLrHLvMX3CvyowzCabzR" %} {% file src="/files/fA6u2o28k7AvtAVenC0c" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
