From the protocol bench

Architecture decisions, simulation results, and audit prep — written by the engineers shipping ChainNextGen Vault and client builds.

Why we chose isolated markets over pooled lending for ChainNextGen Vault

Pooled lending optimizes capital efficiency. Isolated markets optimize survivability when one asset blows up. Here is the trade-off we made for v0.4.

YieldRouter v0.4: routing deposits without rehypothecation risk

Vault deposit() now calls routeDeposit() with explicit pool caps. A walkthrough of the call path we wired for internal QA.
