I'm giga bullish and interested in 
1. Succinct labs
2. MegaETH
3. Wayfinder

Previously I felt fomo for monad but it feels too over rated and too much grind now. I'd rather play once their mainnet launches and look for rewards than becoming another test net user trying and click shit non stop.

Wayfinder gave a nice airdrop for people on twitter who talked about them, 
Succinct still running a limited invite based testnet.

MegaETH got noise and few other kick ass dapps to try. 
Succinct and MegaETH will cook hard.
