Title: AaveV3Adapter

Authors: David Dada <daveproxy80@gmail.com> (https://github.com/dadadave80), Modified from Aave V3 (https://github.com/aave-dao/aave-v3-origin)

Diamond facet adapting an Aave v3 supply (+ optional leverage) position into a Lattice vault strategy. Implements IStrategy (funds routing), IProtocolAdapter (sidecar), and IAaveV3Adapter (Aave config). All logic lives in AaveV3AdapterLib.

Notes:

  • lattice-version: 0.1.0
  • lattice-source: Lattice original

Functions

asset

Returns the address of the underlying asset this strategy manages.

function asset() external view virtual override returns (address);

Returns

NameTypeDescription
<none>address

totalAssetsManaged

Returns the current total asset balance managed by this strategy.

This value is trusted by the StrategyManager and VaultCore for accounting. Strategy implementations MUST report accurate balances to avoid mispricing vault shares.

function totalAssetsManaged() external view virtual override returns (uint256);

Returns

NameTypeDescription
<none>uint256

withdraw

Withdraws amount of the underlying asset to to.

Called by the StrategyManager during rebalancing to recall excess allocations. The strategy is responsible for executing the ERC-20 transfer.

function withdraw(uint256 amount, address to) external virtual override returns (uint256 withdrawn);

Parameters

NameTypeDescription
amountuint256Amount of underlying asset to withdraw.
toaddressRecipient address (typically the vault).

Returns

NameTypeDescription
withdrawnuint256Actual amount transferred (may be less if strategy has slippage).

deploy

Sweeps the adapter's idle asset balance into the external protocol.

Required because the vault PUSHES funds via a bare ERC-20 transfer (no callback). Reverts ProtocolAdapterNothingToDeploy if the idle balance is zero.

function deploy() external virtual override returns (uint256 deployed);

Returns

NameTypeDescription
deployeduint256The amount swept into the protocol.

harvest

Claims reward tokens from the protocol and forwards them RAW (no swap) to the configured recipient.

Safe against zero-claim and fee-on-transfer reward tokens; never reverts withdraw.

function harvest() external virtual override;

emergencyWithdraw

Fully exits the protocol position and returns all recovered assets to the vault.

Intended for the emergency path; callable by an authorized guardian/admin even when the adapter is paused.

function emergencyWithdraw() external virtual override returns (uint256 recovered);

Returns

NameTypeDescription
recovereduint256The amount returned to the vault.

isPaused

Returns true when the adapter is paused or emergency-stopped, or the external protocol reports the asset paused/frozen. When true, deploy() must be a no-op path (revert), so a paused protocol cannot brick rebalance().

function isPaused() external view virtual override returns (bool);

Returns

NameTypeDescription
<none>bool

healthFactor

Returns the current health factor (WAD, 1e18 == 1.0) of the adapter's position.

Supply-only adapters return type(uint256).max (no debt). Leverage adapters return collateralValue * liquidationThreshold / debtValue.

function healthFactor() external view virtual override returns (uint256);

Returns

NameTypeDescription
<none>uint256

minHealthFactor

Returns the configured minimum health factor (WAD) the adapter must not breach.

function minHealthFactor() external view virtual override returns (uint256);

Returns

NameTypeDescription
<none>uint256

rewardRecipient

Returns the address rewards are forwarded to.

function rewardRecipient() external view virtual override returns (address);

Returns

NameTypeDescription
<none>address

setOperator

Sets the authorized operator permitted to call deploy/withdraw/harvest.

Admin-gated (DEFAULT_ADMIN_ROLE). Rejects address(0); emits IProtocolAdapter.OperatorSet.

function setOperator(address operator_) external virtual override;

Parameters

NameTypeDescription
operator_addressThe new operator (typically the StrategyManager diamond).

operator

Returns the authorized operator (zero until wired).

function operator() external view virtual override returns (address);

Returns

NameTypeDescription
<none>address

reentrancyGuardEntered

True while a guarded op is executing — mirrors StrategyManager so VaultCore can reject share-price-sensitive ops mid-deploy/withdraw (read-only reentrancy guard).

function reentrancyGuardEntered() external view virtual returns (bool);

Returns

NameTypeDescription
<none>bool

addressesProvider

Returns the Aave PoolAddressesProvider this adapter resolves the Pool from.

function addressesProvider() external view virtual override returns (address);

Returns

NameTypeDescription
<none>address

aToken

Returns the live aToken for the configured asset (resolved via the provider).

function aToken() external view virtual override returns (address);

Returns

NameTypeDescription
<none>address

vault

Returns the vault this adapter returns withdrawn funds to.

function vault() external view virtual override returns (address);

Returns

NameTypeDescription
<none>address

eModeCategory

Returns the current eMode category id set on the Pool for this adapter.

function eModeCategory() external view virtual override returns (uint8);

Returns

NameTypeDescription
<none>uint8

rewardsController

Returns the configured Aave rewards controller (address(0) if unset).

function rewardsController() external view virtual override returns (address);

Returns

NameTypeDescription
<none>address

setEMode

Sets the Aave eMode category (admin only). Used to enable correlated-asset looping.

function setEMode(uint8 categoryId) external virtual override;

Parameters

NameTypeDescription
categoryIduint8

setMinHealthFactor

Sets the minimum health-factor floor in WAD (admin only). Must be >= 1e18.

function setMinHealthFactor(uint256 minHealthFactorWad) external virtual override;

Parameters

NameTypeDescription
minHealthFactorWaduint256

setRewardRecipient

Sets the reward recipient (admin only).

function setRewardRecipient(address recipient) external virtual override;

Parameters

NameTypeDescription
recipientaddress

setRewardsController

Sets the Aave rewards controller (admin only).

function setRewardsController(address controller) external virtual override;

Parameters

NameTypeDescription
controlleraddress

lever

Borrows borrowAmount of the asset and re-supplies it, increasing leverage.

Reverts ProtocolAdapterHealthFactorBreached if the resulting HF < the floor.

function lever(uint256 borrowAmount) external virtual override;

Parameters

NameTypeDescription
borrowAmountuint256

delever

Withdraws collateralToPull of the asset from supply and repays that much debt, decreasing leverage and restoring HF.

function delever(uint256 collateralToPull) external virtual override returns (uint256 repaid);

Parameters

NameTypeDescription
collateralToPulluint256

Returns

NameTypeDescription
repaiduint256The amount of debt repaid.

exportSelectors

ERC-8153 selector export: this facet's cuttable selectors, tightly packed (4 bytes each).

Excludes exportSelectors() itself (0x0ef22643) - it is never cut into a diamond. Order matches forge inspect AaveV3Adapter methodIdentifiers (alphabetical by signature); kept in exact parity by ExportSelectorsParityTest.
