address constant NATIVE = 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE;

Functions

constructor

constructor(address superRegistry_);

validateLiqDstChainId

validates the destination chainId of the liquidity request

function validateLiqDstChainId(
    bytes calldata txData_,

)
    external
    pure
    virtual
    override
    returns (bool);

Parameters

Name	Type	Description
`txData_`	`bytes`	the txData of the deposit
`liqDstChainId_`	`uint64`	the chainId of the destination chain for liquidity

validateReceiver

decoded txData and returns the receiver address

function validateReceiver(
    bytes calldata txData_,
    address receiver_
)
    external
    pure
    virtual
    override
    returns (bool valid_);

Parameters

Name	Type	Description
`txData_`	`bytes`	is the txData of the cross chain deposit
`receiver_`	`address`	is the address of the receiver to validate

Returns

Name	Type	Description
`valid_`	`bool`	if the address is valid

validateTxData

validates the txData of a cross chain deposit

function validateTxData(ValidateTxDataArgs calldata args_) external view virtual override;

Parameters

Name	Type	Description
`args_`	`ValidateTxDataArgs`	the txData arguments to validate in txData

decodeMinAmountOut

decodes the txData and returns the minimum amount expected to receive on the destination

    bytes calldata txData_,
    bool genericSwapDisallowed_
)
    external
    view
    virtual
    override
    returns (uint256 amount_);

Parameters

Name	Type	Description

Returns

Name	Type	Description
`amount_`	`uint256`	the amount expected

decodeAmountIn

decodes the txData and returns the amount of external token on source

    bytes calldata txData_,
    bool genericSwapDisallowed_
)
    external
    view
    virtual
    override
    returns (uint256 amount_);

Parameters

Name	Type	Description

Returns

Name	Type	Description
`amount_`	`uint256`	the amount expected

decodeDstSwap

decodes the amount in from the txData that just involves a swap

function decodeDstSwap(bytes calldata txData_)
    external
    pure
    virtual
    override
    returns (address token_, uint256 amount_);

Parameters

Name	Type	Description
