Blast to Shut Down Layer 2, Citing Unsustainable Costs

The wind-down of a Layer 2 whose economics never closed is a reminder that rollup costs are a fixed bill, not a variable one, and that a bridge balance is not the same as a viable chain. The immediate practical issue is the withdrawal window: users have a deadline, while contracts face a separate, longer path, which historically creates a split between those who exit cleanly and those who do not. Whether the remaining bridge value clears before the cutoff, and how the contract-based withdrawals are handled afterward, is the part worth watching.
