Flow Mainnet-28 Protocol Fix Deployed on December 28 as Network Stays in Idle Read-Only Mode

On December 28, the Flow Foundation’s Mainnet-28 protocol fix was approved and deployed by validators, placing the blockchain into an idle, read-only state with transactions halted. This security-focused posture follows a reported $3.9 million exploit that impacted user assets and has temporarily disrupted DeFi and cross-chain activity on the network. On the same date, FLOW traded at $0.12 with a market cap of $193.10 million, registering a 31.54% daily price drop alongside a sharp rise in trading volume.
