On October 2023, Hopelend was exploited in a precision loss, resulting in approximately $825K in losses. That makes the Hopelend exploit the 97th largest DeFi incident out of 690 documented in our archive.
Attack Mechanics: How the Hopelend Precision Loss Played Out
Exploit Class Applied to Hopelend
The Hopelend incident on October 18, 2023 is classified as a Precision Loss. Rounding errors in token math let the attacker extract small but repeatable profits. In the full archive, Hopelend is 1 of 8 documented precision loss incidents.
Hopelend in Context
At $825K, the Hopelend exploit is a minor (<$1M) event compared to the largest same-class incident in our archive — BalancerV2 (2025) at $120M.
Prior Precision Loss Before Hopelend
The nearest precision loss incident before Hopelend was MidasCapitalXYZ, 123 days earlier on June 17, 2023 ($600K lost). The same exploit class surfaced again within the precision loss attack surface.
Hopelend Vulnerability Signature
The primary source categorises the Hopelend exploit specifically as “Div Precision Loss”. This narrower label is entity-specific: it reflects how the Hopelend contract failed, rather than the broad precision loss pattern alone.
