USENIX study: over 63% of EIP-7702 authorization transactions tied to malicious contracts
A peer-reviewed study presented at USENIX Security '26 (August 2026) found 924 malicious contract accounts across seven chains that support EIP-7702, with more than $2.3 million in losses and over 10 million users exposed. The authors say over 63% of authorization transactions in their data were linked to attacks on regular wallets, and nearly half of the most-authorized contracts were attacker-controlled. The study window ends in mid-2025, so it measures early abuse, not today's rate. It confirms that 7702 delegation is a major phishing and key-theft sweep vector.

Wallet holder loses $1.65M after signing an unlimited token approval on a fake exchange
In early July 2026 a crypto wallet holder connected to a fake exchange site and signed a malicious contract approval that gave the attacker unlimited spending rights. An automated sweeper then emptied the wallet of about $1.65 million. Anyone who signs approvals on unfamiliar trading sites is at risk; check and revoke token approvals you do not recognise.
