State Variables

yearnV3StrategyInfo

Mapping to store YearnV3Strategy-specific information Maps strategy address to YearnV3StrategyInfo

mapping(address => YearnV3StrategyInfo) public yearnV3StrategyInfo

Functions

createStrategy

Deploy a new YearnV3 strategy

Deterministic salt derived from all parameters to avoid duplicates

function createStrategy(
    address _yearnVault,
    address _asset,
    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
_yearnVault	address	Yearn v3 vault address to compound into
_asset	address	Underlying asset address
_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
<none>	address	strategyAddress Deployed YearnV3Strategy 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

    address indexed strategyAddress,
    string vaultTokenName
);

Parameters

Name	Type	Description
management	address	Management address for the deployed strategy
donationAddress	address	Donation destination address for strategy
strategyAddress	address	Deployed strategy address
