ERC20Default

The default wallet adapter. It reports plain ERC-20 and native-token balances held directly by an account, for every asset on its inclusion list.

The default wallet adapter. It reports plain ERC-20 and native-token balances held directly by an account, for every asset on its inclusion list. It is auto-deployed by NAVCalculator.initialize() and cannot be removed.

Positions returned

One position per inclusion-list asset with a non-zero wallet balance.

Leg	PositionKind	isDebt	Description
Wallet balance	Wallet	false	Plain ERC-20 balance, or native-token balance for the ERC-7528 sentinel 0xEeee…EeeE

Only assets on the adapter's inclusion list (_supportedAssets) are reported; zero balances are skipped.

Balance calculation

ERC20Default adapter — how the underlying balances reported to the NAV Calculator are derived.

For each supported asset:

if asset == NATIVE_ADDRESS (0xEeee…EeeE):  amount = account.balance
else:                                       amount = IERC20(asset).balanceOf(account)

balanceOf is read via a low-level staticcall, so a non-contract or reverting asset yields 0 rather than reverting the whole read. All entries are credit (isDebt = false).

Identity

Constructor

constructor(address navCalculator_, address[] memory initialAssets)

Parameter	Description
navCalculator_	NAVCalculator address (must be non-zero); source of the asset registry
initialAssets	Assets pre-added to the inclusion list at construction (e.g. NATIVE_ADDRESS), so NAVCalculator.initialize need not call back into the proxy during init

---

Registration

This adapter is deployed automatically inside NAVCalculator.initialize() and cannot be removed. Its per-asset reporting is muted/unmuted through the NAV Calculator, which is the only caller permitted to change the inclusion list:

function excludeAssetFromDefaultAdapter(address asset) external;  // → removeSupportedAsset
function includeAssetInDefaultAdapter(address asset) external;    // → addSupportedAsset

Excluding an asset (e.g. one already covered by a custom adapter) avoids double-counting without unregistering it. addSupportedAsset requires the asset to be registered in NAVCalculator.
