IAmbImplementation

Author: ZeroPoint Labs

interface for arbitrary message bridge implementation

Functions

dispatchPayload

allows state registry to send message via implementation.

function dispatchPayload(
    address srcSender_,
    uint64 dstChainId_,
    bytes memory message_,
    bytes memory extraData_
)
    external
    payable;

Parameters

Name	Type	Description
`srcSender_`	`address`	is the caller (used for gas refunds)
`dstChainId_`	`uint64`	is the identifier of the destination chain
`message_`	`bytes`	is the cross-chain message to be sent
`extraData_`	`bytes`	is message amb specific override information

estimateFees

not all AMBs will have on-chain estimation for which this function will return 0

returns the gas fees estimation in native tokens

function estimateFees(
    uint64 dstChainId_,
    bytes memory message_,
    bytes memory extraData_
)
    external
    view
    returns (uint256 fees);

Parameters

Name	Type	Description
`dstChainId_`	`uint64`	is the identifier of the destination chain
`message_`	`bytes`	is the cross-chain message
`extraData_`	`bytes`	is any amb-specific information

Returns

Name	Type	Description
`fees`	`uint256`	is the native_tokens to be sent along the transaction
