Title: BaseERC4626StrategyFactory

Author: Golem Foundation

Abstract base factory for ERC4626-based yield donating strategies

Uses CREATE2 for deterministic deployments; records deployments via BaseStrategyFactory This factory provides shared logic for deploying strategies that deposit into ERC4626 vaults. Child factories must implement _getCreationCode() to provide the specific strategy bytecode.

Functions

createStrategy

Deploy a new ERC4626-based strategy

Deterministic salt derived from all parameters to avoid duplicates

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

Parameters

Name	Type	Description
_targetVault	address	ERC4626 vault address to deposit into
_asset	address	Underlying asset address (must match vault's asset)
_name	string	Strategy share token name
_symbol	string	Strategy share token symbol
_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
strategyAddress	address	Deployed strategy address

_getCreationCode

Returns the creation code for the strategy contract

function _getCreationCode() internal pure virtual returns (bytes memory);

Returns

Name	Type	Description
<none>	bytes	The bytecode of the strategy contract (without constructor args)

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

_createStrategyInternal

Internal function to deploy strategy with given parameters

function _createStrategyInternal(CreateStrategyParams memory params) internal returns (address strategyAddress);

Parameters

Name	Type	Description
params	CreateStrategyParams	Strategy creation parameters

Returns

Name	Type	Description
strategyAddress	address	Deployed strategy address

Events

Emitted on successful strategy deployment

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

Parameters

Name	Type	Description
deployer	address	Transaction sender performing deployment
targetVault	address	ERC4626 vault address the strategy will deposit into
donationAddress	address	Donation destination address for strategy
strategyAddress	address	Deployed strategy address
vaultTokenName	string	Vault token name associated with strategy
