Venus Thena (THE) Incident: What Broke and What Was Missed
On March 15, 2026, an attacker bypassed the THE (Thena) supply cap on Venus Protocol (BNB Chain) through a donation attack, inflating a collateral position to 3.67x the intended limit and borrowing ~$14.9M in assets. Both sides lost money on-chain: Venus was left with ~$2.15M in bad debt after 254 liquidation bots competed across 8,048 transactions, while the attacker retained only ~$5.2M against a $9.92M investment. This deep dive examines what broke across three lines of defense (exposure limits, collateral valuation, and liquidation) and the monitoring gaps that left months of on-chain warning signals unacted upon.
