Recently, some people have been arguing again about whether pledge-sharing security is a "matryoshka doll" (nested layers).

I checked a few Layer 2 chains on-chain fees and real interactions, and honestly: security is a cost, not magic.
While stacking yields sounds great, what you're stacking might be correlated risk, and if something goes wrong, it all goes wrong together.

My current approach is pretty simple: set smaller goals.
First, focus on one thing — whether this protocol can maintain users on my frequently used Layer 2, whether the transaction fees are normal, and whether the bridge deposits and withdrawals are smooth.
If I can answer these, then I’ll consider whether to lend out the pledge rights again.
Anyway, don’t mortgage your sleep just for a little more annualized return… that’s the plan for now.
