#黑客攻击与网络安全事件 The on-chain signals from the Flow mainnet security incident are worth paying attention to. Based on the response pace of Upbit and DAXA, this is not a false alarm—pausing deposits and withdrawals plus risk alerts indicate that the exchanges have confirmed the seriousness of the issue.

Focus on several data points:

**Choosing the recovery plan is crucial.** Abandoning a rollback in favor of isolated recovery means the Flow team has weighed the trade-offs between on-chain data integrity and rapid recovery—behind the figure that 99.9% of accounts are unaffected, there are a limited number of illegally minted tokens that need to be isolated. From a fund flow perspective, this could involve millions of dollars in abnormal assets.

**The time cost of phased restart.** The Cadence environment is being brought online first, with EVM temporarily restricted, and a subsequent 24-48 hour repair cycle. This pace means that cross-chain bridging and exchange liquidity will remain limited in the short term. Monitoring the fund flows of FLOW on other exchanges during this period will be very meaningful—arbitrage opportunities or fund runs may occur.

**The reference value of exchange attitudes.** The Korea exchange consortium has explicitly stated that they do not rule out terminating trading support in the future. This warning signal deserves attention. If further issues arise during the recovery process, FLOW’s liquidity could face greater pressure.

Recommended to monitor: timestamps of each recovery phase, the specific scale of illegally minted tokens, and on-chain activity of major holding addresses.
