UNCX Network V2 Smart Contract Vulnerability: $1.49M Reported Loss

·Source-attributed incident record

Incident Overview

UNCX Network’s Vesting V2 contracts had a share-accounting logic vulnerability (VestingManager.cancel failed to ensure retained shares covered already-released amounts). The attacker transferred tokens directly to lower the shares-per-token rate, released and canceled schedules, and drained excess tokens from the shared vesting pool. Initial loss on Ethereum was ~$86k, later escalating to ~$1.49M across multiple chains.
