EthereumEventConfiguration

buildEventInitData

Build initial data for the event contract by extending the event vote data with configuration params.

function buildEventInitData(
        IEthereumEvent.EthereumEventVoteData eventVoteData
    ) internal view returns(
        IEthereumEvent.EthereumEventInitData eventInitData)

Parameters:

---

Name	Type	Description
eventVoteData	EthereumEventVoteData	Event vote data structure, passed by relayer
signatures	bytes[] memory	Payload signatures

deployEvent

Deploys the event contract (creates a new instance of EthereumBaseEvent contract).

function deployEvent(
        IEthereumEvent.EthereumEventVoteData eventVoteData
    ) external override reserveMinBalance(MIN_CONTRACT_BALANCE)

Parameters

Name	Type	Description
eventVoteData	EthereumEventVoteData	Event vote data structure

Events emitted:

• NewEventContract

deriveEventAddress

Derive the Ethereum event contract address from its init data.

function deriveEventAddress(
        IEthereumEvent.EthereumEventVoteData eventVoteData
    ) override public view responsible
    returns(address eventContract)

Parameters:

Type	Description
address	Address to return the remaining gas

EverscaleEventConfiguration

buildEventInitData

function buildEventInitData(
        IEverscaleEvent.EverscaleEventVoteData eventVoteData
    ) internal view returns(
        IEverscaleEvent.EverscaleEventInitData eventInitData)

Parameters:

Name	Type	Description
eventVoteData	EverscaleEventVoteData	Event vote data structure, passed by relayer

Return values:

Name	Type	Description
eventInitData	EverscaleEventVoteData	Initial data for event contract

deployEvent

Deploy event contract (creates new instance of EverscaleBaseEvent contract).

function deployEvent(
        IEverscaleEvent.EverscaleEventVoteData eventVoteData
    ) override external reserveMinBalance(MIN_CONTRACT_BALANCE)

Parameters:

Name	Type	Description
eventVoteData	EverscaleEventVoteData	Event vote data structure

• NewEventContract

deriveEventAddress

Derives the Everscale event contract address from it's initial data.

function deriveEventAddress(
        IEverscaleEvent.EverscaleEventVoteData eventVoteData
    ) override public view responsible
    returns (address eventContract)

Parameters:

Name	Type	Description

Return values:

Name	Type	Description
eventContract	address	Address of the corresponding everscale event contract

onEventConfirmedExtended

Receives "confirm" callback from the event contract and checks event contract correctness. If it's correct, then sends the callback to the proxy with the same signature.

function onEventConfirmedExtended(
        IEthereumEvent.EthereumEventInitData eventInitData,
        TvmCell _meta,
        address gasBackAddress
    ) external override reserveMinBalance(MIN_CONTRACT_BALANCE)

Parameters:

Type	Description
address	Address to return the remaining gas
