Title: AaveV3StrategyFactory

Author: Golem Foundation

Factory for deploying Aave V3 yield donating strategies

Uses CREATE2 for deterministic deployments; records deployments via BaseStrategyFactory AAVE V3 INTEGRATION: This factory deploys strategies that deposit into Aave V3 lending pools to earn yield through interest accrual on supplied assets.

Constants

AAVE_ADDRESSES_PROVIDER

Aave V3 AddressesProvider on Ethereum mainnet

address public constant AAVE_ADDRESSES_PROVIDER = 0x2f39d218133AFaB8F2B819B1066c7E434Ad94E9e

AAVE_REWARDS_CONTROLLER

Aave V3 RewardsController on Ethereum mainnet.

Wired into every deployed strategy so liquidity-mining emissions can be claimed on demand. The controller is a stable, canonical Aave contract; we hardcode it here rather than making it a per-deploy parameter to keep the factory surface small and to prevent operator misconfiguration.

address public constant AAVE_REWARDS_CONTROLLER = 0x8164Cc65827dcFe994AB23944CBC90e0aa80bFcb

USDC

USDC token address on Ethereum mainnet

address public constant USDC = USDC_MAINNET

Functions

createStrategy

Deploy a new AaveV3 strategy

Deterministic salt derived from all parameters to avoid duplicates

function createStrategy(
    string memory _name,
    string memory _symbol,
    address _management,
    address _keeper,
    address _emergencyAdmin,
    address _donationAddress,
    bool _enableBurning,
    address _tokenizedStrategyAddress
) external returns (address);

Parameters

Name	Type	Description
_name	string	Strategy share token name
_symbol	string	Strategy share token symbol (e.g., "osAAVE")
_management	address	Management address (can update params)
_keeper	address	Keeper address (calls report)
_emergencyAdmin	address	Emergency admin address
_donationAddress	address	Dragon router address (receives profit shares)
_enableBurning	bool	True to enable burning shares during loss protection
_tokenizedStrategyAddress	address	TokenizedStrategy implementation address

Returns

Name	Type	Description
<none>	address	strategyAddress Deployed AaveV3Strategy address

computeStrategyAddress

Compute the deterministic address where a strategy will be deployed

Must be implemented by child factories using their own bytecode

function computeStrategyAddress(
    address _vault,
    address _asset,
    string memory _name,
    string memory _symbol,
    address _management,
    address _keeper,
    address _emergencyAdmin,
    address _donationAddress,
    bool _enableBurning,
    address _tokenizedStrategyAddress,
    address _deployer
) public view override returns (address);

Parameters

Name	Type	Description
_vault	address	Vault address (e.g., Yearn vault, or factory constant for hardcoded vaults)
_asset	address	Underlying asset address (or factory constant for hardcoded assets)
_name	string	Strategy share token name
_symbol	string	Strategy share token symbol
_management	address	Management address
_keeper	address	Keeper address
_emergencyAdmin	address	Emergency admin address
_donationAddress	address	Donation address
_enableBurning	bool	Enable burning flag
_tokenizedStrategyAddress	address	TokenizedStrategy implementation
_deployer	address	Address that will deploy the strategy

Returns

Name	Type	Description
<none>	address	Predicted strategy address

Events

StrategyDeploy

Emitted on successful strategy deployment

event StrategyDeploy(
    address indexed deployer,
    address indexed donationAddress,
    address indexed strategyAddress,
    string vaultTokenName
);

Parameters

Name	Type	Description
deployer	address	Transaction sender performing deployment
donationAddress	address	Donation destination address for strategy
strategyAddress	address	Deployed strategy address
vaultTokenName	string	Vault token name associated with strategy
