Operational notes

Idle Finance vaults have no pending actions. Yield accrues automatically.
Junior tranches earn higher APYs but bear the first loss in case of underlying strategy issues. Senior tranches are protected but earn less.
Vaults leverage various DeFi protocols including Lido, Instadapp, Steakhouse, Gearbox, and Ethena.
