Two Ethereum L2s announced shutdowns in one week. What's happening, why, and what to do if you bridged during the airdrop era. Blast went first on October 2. It once held around $2.3B, but TVL had fallen to about $32M, and the team said the chain now costs more to run than it earns. Four days later, Abstract, the chain behind Pudgy Penguins, followed after losing tens of millions funding it. The reason is mostly economics. Posting data to Ethereum got much cheaper, and activity has concentrated in a few big L2s. Once airdrop farmers leave, smaller chains struggle to pay their own bills. If you still have funds on Blast, Abstract or Silicon, each network has announced its own deadline, and the earliest one is this month. Check the details only through the project's official channels, and ignore anyone in your DMs offering to help you move funds.
