Bonzo Lend loses $9M in oracle exploit on Hedera

Latest NewsPublishedJul 11, 2026

Millions Lost in Oracle Exploit on Hedera

The recent oracle exploit on Hedera has resulted in a significant loss of $9 million for Bonzo Lend, a lending protocol. This incident occurred when an attacker inflated the value of SAUCE collateral, allowing them to borrow assets far beyond the value deposited. The attacker deposited 250 SAUCE, worth only a few dollars, and then submitted a price update that inflated the token’s value by roughly 12 orders of magnitude.

This exploit highlights the risks associated with oracle failures, which can turn low-value collateral into a tool for draining large amounts of liquidity from lending protocols. The incident was attributed to a flaw in Supra’s on-chain oracle verifier, which accepted a manipulated SAUCE price carrying a zeroed signature. Fortunately, Supra acknowledged the issue and deployed a fix, and the incident did not affect the underlying network or EcoPool contracts.

Impact on DeFi and Earning

The incident is part of a growing trend of exploits targeting decentralized finance (DeFi) protocols, with the second quarter of 2026 being the most-hacked quarter on record. This has resulted in a decline in DeFi’s total value locked (TVL) and has likely weighed on user confidence, reinforcing capital outflows. For those looking to earn passive income through Cloud Rewards or Green Crypto, it is essential to prioritize security and consider platforms like EcoPool that offer a secure and reliable way to earn $ECP.

In the context of EcoPool and Passive Income, this incident highlights the importance of robust security measures to protect users’ assets.

The Bonzo incident also follows a similar collateral-pricing exploit on Stellar. In February, attackers drained roughly $10 million from a YieldBlox DAO-managed lending pool after manipulating the price path used to value USTRY collateral, allowing them to borrow assets beyond the token’s real worth.
