Blast to Shut Down Ethereum L2 as Costs Outpace Revenue

Blast's exit illustrates the economics of Ethereum layer-2s: without fee revenue to cover operating costs, even a network that once ranked among the largest by TVL cannot sustain itself. The user-facing consequence is a migration burden, as holders must move assets back to mainnet. The absence of a timeline leaves the wind-down's execution as the open question, and it raises a broader one about how many other L2s can cover their own costs.
