Tendril Protocol Exploit Drains $555,000 in USDT Stablecoin

Key Facts

1The Tendril protocol suffered an exploit resulting in the drain of approximately $555,000 in USDT stablecoin.
2The exploit was caused by a flaw in the 'sell hook' logic within the protocol's custom token smart contracts.

The Tendril protocol suffered a security exploit resulting in the drain of approximately $555,000 in USDT stablecoin on November 5, 2026. Crypto Briefing reported that the breach was caused by a flaw in the 'sell hook' logic within the protocol's custom token smart contracts, which allowed an attacker to withdraw liquidity from the PancakeSwap V2 pool on BNB Chain.

Reports indicated that the programming flaw enabled the attacker to manipulate liquidity ratios, making the TENDRIL token appear more valuable relative to USDT before withdrawing nearly the entire balance. Security teams including ExVul and ScaleBit issued public alerts regarding the attack on November 5, 2026, while monitoring services continue to track the incident's impact on the protocol's liquidity.
