Storage Layout
For non-default storage allocations (e.g. EIP-7201) check out 
| Slot | Offset | Bytes | Label | Type | Contract |
|---|---|---|---|---|---|
| 0 | 0 | 32 | wards | mapping(address ⇒ uint256) | src/UsdcVault.sol:UsdcVault |
| 1 | 0 | 32 | totalSupply | uint256 | src/UsdcVault.sol:UsdcVault |
| 2 | 0 | 32 | balanceOf | mapping(address ⇒ uint256) | src/UsdcVault.sol:UsdcVault |

| 4 | 0 | 32 | nonces | mapping(address ⇒ uint256) | src/UsdcVault.sol:UsdcVault |
Transient Storage Layout
Transient storage layout is only available for Solidity contracts compiled with version ≥ 0.8.27.
