By definition an "L2 scaling solution" is not the Ethereum blockchain. Ethereum itself clearly is a secure blockchain given the fact that it has not been exploited directly ever, as far as I am aware. Smart contracts running in the EVM obviously have exploits galore, but that is different from Ethereum itself being vulnerable. Just like it is different when the Java Virtual Machine itself has an exploit (uncommon) vs when a program that runs in the JVM does (very common). You can of course argue that the lack of inherent soundness / correctness in Ethereum smart contracts makes the entire chain less useful since running smart contracts is kinda the whole point, but then you should make that argument rather than saying dumb things like: > ETH was an insecure blockchain
