Suppose a smart contract on a certain chain has a vulnerability, and an attacker can exploit this flaw to control 37% of the token supply, then concentrate on selling—what consequences might this bring? First, a sharp drop in the token price. When a large amount of selling pressure suddenly floods the market, liquidity is instantly overwhelmed, buyers retreat, and prices spiral out of control. Second, the complete collapse of ecosystem confidence. Once investors realize that the contract itself has such a flaw, trust in the project evaporates immediately, and no one is willing to take over later. Furthermore, such incidents often trigger chain reactions—exchanges may urgently delist the token, auditing firms' reputations are damaged, and the entire token economic model is thoroughly dismantled. This is why contract audits and multi-signature mechanisms are so critical. A 37% concentrated sell-off event is enough to destroy an entire project's ecosystem.
