Update on L2s for you guys!
$STRK is attracting attention for developing L2 building solutions for the Bitcoin ecosystem using zero-knowledge (zk) technology. This has long attracted the attention of professional investors in the industry.
$ARB has started a gamefi incentive program and seems to be keeping a lot of interesting information under wraps.
$OP has completed the "Fraud Proof" upgrade and has received praise from Vitalik Buterin.
Among layer 2, $ARB and $OP appear to be the most mature projects, both being in phase 1 and ready to decentralize the network through participation in the staking process.
As for $ZK - Zksync, there still doesn't seem to be much news other than preparations for distributing salaries to the community.
