On December 2023, CCV was exploited in a precision loss on BNB Chain, resulting in approximately $3.2K in losses. That makes the CCV exploit the 421st largest DeFi incident out of 690 documented in our archive.
Attack Mechanics: How the CCV Precision Loss Played Out
Exploit Class Applied to CCV
The CCV incident on December 28, 2023 is classified as a Precision Loss. Rounding errors in token math let the attacker extract small but repeatable profits. In the full archive, CCV is 1 of 8 documented precision loss incidents.
CCV in Context
At $3.2K, the CCV exploit is a minor (<$1M) event compared to the largest same-class incident in our archive — BalancerV2 (2025) at $120M.
Prior Precision Loss Before CCV
The nearest precision loss incident before CCV was KyberSwap, 36 days earlier on November 22, 2023 ($48M lost). The same exploit class surfaced again within the precision loss attack surface.
Target Chain: BNB Chain
The vulnerable CCV contract was deployed on BNB Chain — one of 23 documented incidents on BNB Chain. This determines the block cadence, mempool, and forensic tooling available to investigators.
Impact & Recovery for CCV
CCV Loss Figure
The CCV exploit caused $3,200 in losses — a minor (<$1M) incident and the 152nd largest of 214 documented in 2023.
Where CCV Sits Among Precision Loss Attacks
Ranked by loss size, CCV is the 7th largest of 8 precision loss incidents documented. That puts the CCV loss below the class average of $27.06M.
Timeline Since the CCV Incident
The CCV exploit occurred 2.3 years ago (838 days). The contract, its fork-block, and the attack transaction remain on-chain and forensically reproducible.
