ERC20BaseStorage

Defines the storage layout for the core ERC20 token functionality Uses the diamond storage pattern to avoid storage collisions in upgradeable contracts

Layout

Storage layout structure for ERC20 token data

Parameters

Name	Type	Description

struct Layout {
  mapping(address => uint256) balances;
  mapping(address => mapping(address => uint256)) allowances;
  uint256 totalSupply;
}

STORAGE_SLOT

bytes32 STORAGE_SLOT

Unique storage slot for ERC20 base storage Generated using the contract's full path to ensure uniqueness Used in diamond storage pattern to prevent storage collision with other facets

layout

function layout() internal pure returns (struct ERC20BaseStorage.Layout l)

Provides access to the storage layout

Return Values

Name	Type	Description
l	struct ERC20BaseStorage.Layout	Storage layout struct with proper positioning Uses assembly to position the storage struct at the predetermined slot
