USDD Gas Audit Finds 15-25% Savings Potential, Low Direct Security Risk

An independent gas-efficiency audit of the USDD stablecoin, which has roughly $1.17 billion in total value locked across Ethereum and several Layer 2 networks, was completed on 28 October 2026. The review identified 36 inefficiencies spanning storage layout, loops, external calls, and transfer logic, with the largest costs arising in bridge calls and whitelist iteration. Optimizing the most-used functions such as mint, burn, and rebalance could cut gas costs by an estimated 15-25%. The auditor found no critical security flaws directly caused by these inefficiencies, though unbounded loops could enable denial-of-service via gas griefing. The overall risk score was assessed at 3 out of 10, indicating low-to-medium economic risk.
