Core Protocol Components

Ethereum Vault Connector (EVC)

The EVC is the foundational layer mediating between vaults. It provides:

Batching: Execute multiple operations atomically
Sub-accounts: 256 isolated positions per address
Operators: Delegate control over your accounts to other addresses
Deferred checks: Temporarily violate constraints within a batch

Euler Vault Kit (EVK)

Credit vaults extending ERC-4626 with borrowing:

Standard ERC-4626 deposit/withdraw/mint/redeem
Borrow and repay functionality
Collateral and controller management
LTV ratios (borrow LTV vs liquidation LTV)

How to Use
