Hey there,
there was a more recent discussion about whether or not L2 were a lead followed by Morpho.
At that time it was still not the priority. Morpho focuses on creating a full grown product (protocol!) and Ethereum seems the best place for that now.
You can check the details of the discussions here:
Although this may have changed, I think that with the new changes coming to Morpho (those teased in the latest communications), the focus is still on Ethereum.
But I may be wrong, and the move to a protocol state that doesn’t depend on an underlying decentralized brokers could more easily be multiplied on other blockchains!
