Overview##
In July 2025, Liquid Loot engaged Obsidian Audits for a 5-day audit of their NFT lending smart contracts.
Following the audit and fix-review, Liquid Loot had a second review from Three Sigma, a top-tier security auditing firm.
This case study highlights how Obsidian’s audit identified and helped resolve multiple high severity issues in Liquid Loot's codebase, resulting in no major vulnerabilities being reported by the subsequent review.
