CoW Swap’s website was hijacked via a DNS attack on April 14 2026, leading the DAO to shut down the frontend and pause backend APIs while warning users to avoid the site and revoke token approvals; the incident knocked the COW token 3% lower to $0.2159【1】.

The DAO behind CoW Swap announced on X that an unknown party redirected traffic from its official domain (swap.cow.fi) through a DNS hijack, a technique that reroutes users to a malicious look‑alike site. The team responded by locking the domain, flagging the frontend as malicious, and pausing both the website and its APIs as a precautionary measure【2】. While the on‑chain contracts remain intact, the attack creates immediate user‑level risk, prompting Blockaid to advise users not to sign any transactions and to revoke existing token approvals【2】.
Following the announcement, the COW token fell more than 3% to $0.2159, down from $0.2229 the day before【1】. This move mirrors a broader trend of DeFi front‑end attacks; Balancer suffered a similar DNS incident in 2023 and Curve Finance reported multiple hijackings, underscoring the persistent vulnerability of web layers in otherwise secure smart‑contract ecosystems【1】. Hacken’s Q1 2026 report highlighted that phishing and social‑engineering hacks cost Web3 projects $482 million across 44 incidents, reinforcing the financial stakes of such attacks【1】.
CoW Swap’s DAO urged users to stay away from swap.cow.fi until the platform is confirmed safe and to revoke any token approvals that may have been granted to the compromised site【1】【2】. The protocol’s core systems, including its backend and APIs, were paused “as a precaution,” but no on‑chain funds were reported as stolen or at risk【2】.
The hijack highlights that even well‑audited DeFi protocols remain exposed at the user interface level; how quickly CoW Swap can secure its domain and restore trust will shape the token’s short‑term trajectory and may influence broader market sentiment toward DeFi front‑end security.

It uses a "Coincidence of Wants" mechanism that matches complementary user intents within batch auctions, allowing direct swaps without relying on AMMs.
By batching orders and settling them at a uniform clearing price, the protocol prevents front‑running and sandwich attacks, and off‑chain solvers compete to find the best execution.
Approximately $87 billion, more than double the $40.2 billion recorded in 2024.
It adds Bitget’s own DEX trading API as a dedicated solver and routes orders through its aggregated liquidity across over 110 protocols on multiple chains.
COW is used for governance in CowDAO and provides utility such as protocol fee discounts and other ecosystem perks.
