A major DNS hijack incident affecting the leading DEXs on Base and Optimism has raised fresh concerns over user security.
Over the weekend, two major decentralized exchanges, Aerodrome and Velodrome, issued an urgent security alert, warning that their primary domains had been compromised. Teams stressed that the problem was limited to the front end and that all smart contracts remained secure.
Aerodrome, the largest DEX on Base, and Velodrome, the leading DEX on Optimism, said a DNS hijack attack that began early in the day could redirect users to fake interfaces even when typing the correct URL. Both teams urged users to avoid all platform links until full control is restored, despite previously offering decentralized mirror access points.
The incident echoes a similar attack from November 2023, when both protocols suffered a DNS compromise that resulted in losses exceeding 100,000 dollars. Meanwhile, Dromos Labs recently announced that the two platforms will merge under a unified AERO structure in a new system set to launch in the second quarter of 2026.
