Critical Alert: Company Coinone Delists Port3 (PORT3) Token on January 26 After Security Breach

Company Coinone has announced the termination of trading support for Company Port3's token Port3 (PORT3) effective January 26, 2025 at 06:00 UTC. The delisting follows a serious security breach that resulted in unauthorized creation and issuance of additional tokens on November 23, 2025. As an exchange-level protective measure, Company Coinone designated PORT3 as an investment warning item before deciding to delist after unsatisfactory remediation evidence from the project team.

The move underscores the growing role of centralized exchanges in protecting users by applying strict risk controls and highlights the importance of robust smart contract security for token projects. When a reputable platform like Company Coinone delists an asset, the market interprets this as a significant blow to the token's credibility and liquidity.

Immediate actions for holders: If you hold PORT3 on Company Coinone, you must act before the cutoff. The recommended steps are: 1) Withdraw tokens to a private, self-custody wallet that supports PORT3; 2) Check whether other exchanges still list PORT3, noting that listings on less-regulated venues carry higher risk; 3) Monitor official channels for any withdrawal-only deadlines announced by Company Coinone. Delisting often reduces liquidity and can leave assets stranded if users fail to withdraw during the grace period.

Why this matters: The reported unauthorized minting and issuance of additional tokens on November 23 represents a profound tokenomics and security failure. Company Port3's inability to provide verifiable remediation details convinced Company Coinone that continuing support would present an unacceptable risk to customers. Exchanges act as market gatekeepers; their delisting decisions communicate crucial trust signals. Market participants should treat delisting events as red flags that often precede price declines and reduced market depth.

Market and analysis implications: From an analysis perspective, exchange delistings following a security incident typically cause immediate downward pressure on price and trading volume. Liquidity providers withdraw, market makers widen spreads, and retail confidence may evaporate. Even if PORT3 remains tradeable elsewhere, the loss of a major venue like Company Coinone increases slippage and execution risk. Traders should be prepared for heightened volatility and consider tighter risk management, including stop-loss strategies, reducing position sizes, and avoiding leverage on this asset.

Wider lessons for the crypto ecosystem: This incident reinforces three essential practices: (1) Projects must prioritize security audits and transparent incident response; (2) Exchanges must enforce high standards and act decisively to protect users; (3) Investors should maintain custody discipline and diversify exchange exposure.

Conclusion: The Company Coinone delist of Port3 (PORT3) is a protective but impactful action prompted by a confirmed security lapse and insufficient remediation. Holders must act quickly to withdraw tokens and reassess exposure. From an analytical standpoint, this event is a cautionary reminder that technical security and transparent governance are critical to token longevity and market trust.
