Manages the swaps

Methods

WETH9

Returns the address of WETH9

Solidity

function WETH9() external view returns (address)

Returns

Name	Type	Description
_0	address	undefined

deposit

Deposits funds into the margin of a Primitive Engine

Solidity

function deposit(address recipient, address risky, address stable, uint256 delRisky, uint256 delStable) external payable

Details

Since the PrimitiveManager contract keeps track of the margins, it will deposit the funds into the Primitive Engine using its own address

Parameters

Name	Type	Description
recipient	address	Address receiving the funds in their margin
risky	address	Address of the risky token
stable	address	Address of the stable token
delRisky	uint256	Amount of risky token to deposit
delStable	uint256	Amount of stable token to deposit

depositCallback

Triggered when depositing tokens to an Engine

Solidity

function depositCallback(uint256 delRisky, uint256 delStable, bytes data) external nonpayable

Parameters

Name	Type	Description
delRisky	uint256	Amount of risky tokens required to deposit to risky margin balance
delStable	uint256	Amount of stable tokens required to deposit to stable margin balance
data	bytes	Calldata passed on deposit function call

factory

Returns the address of the factory

Solidity

function factory() external view returns (address)

Returns

Name	Type	Description
_0	address	undefined

margins

Returns the margin of an account for a specific Primitive Engine

Solidity

function margins(address, address) external view returns (uint128 balanceRisky, uint128 balanceStable)

Parameters

Name	Type	Description
_0	address	undefined
_1	address	undefined

Returns

Name	Type	Description
balanceRisky	uint128	undefined
balanceStable	uint128	undefined

positionDescriptor

Returns the address of the PositionDescriptor

Solidity

function positionDescriptor() external view returns (address)

Returns

Name	Type	Description
_0	address	undefined

refundETH

Transfers the ETH balance of the contract to the caller

Solidity

function refundETH() external payable

swap

Solidity

function swap(ISwapManager.SwapParams params) external payable

Parameters

Name	Type	Description
params	ISwapManager.SwapParams	undefined

swapCallback

Triggered when swapping tokens in an Engine

Solidity

Parameters

Name	Type	Description
delRisky	uint256	Amount of risky tokens required to pay the swap with
delStable	uint256	Amount of stable tokens required to pay the swap with
data	bytes	Calldata passed on swap function call

Parameters

Name	Type	Description
token	address	Address of the token to sweep
amountMin	uint256	Minimum amount to transfer
recipient	address	Recipient of the tokens

unwrap

Unwraps WETH to ETH and transfers to a recipient

Solidity

function unwrap(uint256 amountMin, address recipient) external payable

Parameters

Name	Type	Description
amountMin	uint256	Minimum amount to unwrap
recipient	address	Address of the recipient

withdraw
