Factory
Voltz Factory Contract
The Factory contract is at the heart of Voltz Protocol and has two key responsibilities:
- Management of external contract approvals to be able to interact with Voltz Protocol positions on behalf of their owners
- Deployment of Interest Rate Swap pools
The
isApproved function checks if a given owner address has approved a given address (contract or externally owned account) to interact with IRS pools on Voltz Protocol on behalf of the owner.function isApproved(address ownerAddress, address trustedAddress) external view returns (_isApproved bool);
Parameters
Name | Type | Description |
|---|---|---|
ownerAddress | address | Address of a Voltz Protocol user |
trustedAddress | address | Contract or externally owned account address |
Returns
Name | Type | Description |
|---|---|---|
_isApproved | bool | true if ownerAddress approved trustedAddress to interact with IRS pools on Voltz Protocol on behalf of ownerAddress |
The
setApproval function lets a given ownerAddress approve (or disapprove) an address (contract or externally owned account) to interact with IRS pools on Voltz Protocol on behalf of the owner.function setApproval(address intAddress, bool allowIntegration) external;
Parameters
Name | Type | Description |
|---|---|---|
trustedAddress | address | Contract or externally owned account address |
_isApproved | bool | If true, sets the approval status of the trustedAddress to true where the owner is the msg.sender, if false, the approval is revoked. |
The deployIRSInstance function deploys a Voltz Interest Rate Swap pool. Each pool on Voltz Protocol has a fixed maturity date and is linked to a yield-bearing pool with a variable rate of return. The deployIRSInstance function can only be called by the owner of the Factory contract.
function deployIrsInstance(address underlyingToken, address rateOracle, uint256 termStartTimestampWad, uint256 termEndTimestampWad, int24 tickSpacing) external returns (address marginEngineProxy, address vammProxy, address fcmProxy)
Parameters
Name | Type | Description |
|---|---|---|
underlyingToken | address | Underlying ERC20 token address (e.g. address of the USDC contract on Ethereum mainnet). |
termStartTimestampWad | uint256 | The Unix block timestamp at which the Interest Rate Pool becomes live (the Wad suffix indicates that this number is scaled by 10^18) |
termEndTimestampWad | uint256 | The Unix block timestamp at which the Interest Rate Pool matures (the Wad suffix indicates that this number is scaled by 10^18) |
tickSpacing | int24 | The VAMM tick spacing. |
Note: Only ticks with indexes that are divisible by tickSpacing can be initialized, i.e. used as boundaries when providing concentrated liquidity. Small choices for tickSpacing allow tighter and more precise ranges, but may cause Interest Rate Swaps to be more gas-intensive (since each initialized tick that a swap crosses imposes a gas cost on the swapper).
Returns
Name | Type | Description |
|---|---|---|
marginEngineProxy | address | Address of the Margin Engine Proxy of the IRS pool |
vammProxy | address | Address of the vAMM Proxy of the IRS pool |
fcmProxy | address | Address of the Full Collateralisation Module Proxy of the IRS pool |
The setMasterFCM function sets the master FCM contract implementation for a given pool.
function setMasterFCM(IFCM _masterFCM, uint8 _yieldBearingProtocolID) external override onlyOwner
Name | Type | Description |
|---|---|---|
_masterFCM | IFCM | Master FCM contract implementation for the corresponding yield bearing protocol ID |
_yieldBearingProtocolID | uint8 | Unique identifier for the yield bearing protocol of a pool...? |
The setMasterMarginEngine function sets the master margin engine contract implementation for a given pool.
function setMasterMarginEngine(IMarginEngine _masterMarginEngine) external override onlyOwner
Name | Type | Description |
|---|---|---|
_masterMarginEngine | IMarginEngine | Master Margin Engine contract implementation. |
The setMasterVAMM function sets the master vamm contract implementation for a given pool.
function setMasterVAMM(IVAMM _masterVAMM) external override onlyOwner
Name | Type | Description |
|---|---|---|
_masterVAMM | IVAMM | Master VAMM contract implementation. |
The setPeriphery function sets the periphery contract implementation for a given pool.
function setPeriphery(IPeriphery _periphery) external override onlyOwner
Name | Type | Description |
|---|---|---|
_periphery | IPeriphery | Periphery contract address |
