# OmnichainExecutorOwner

## OmnichainExecutorOwner

[`OmnichainExecutorOwner` at v2.15.0](https://github.com/VenusProtocol/governance-contracts/blob/v2.15.0/contracts/Cross-chain/OmnichainExecutorOwner.sol) is the upgradeable access-controlled owner of a destination OmnichainGovernanceExecutor. The previous description incorrectly called this contract `OmnichainProposalSender`.

Known selectors are registered by their full function-signature strings. The fallback resolves `msg.sig`, checks the corresponding AccessControlManager permission, and forwards the original calldata to the executor. `upsertSignature` is owner-only; `setTrustedRemoteAddress` and `transferBridgeOwnership` use exact ACM signatures. Ownership renunciation is disabled.

## Solidity API

#### OMNICHAIN\_GOVERNANCE\_EXECUTOR

@custom:oz-upgrades-unsafe-allow state-variable-immutable

```solidity
mapping(bytes4 => string) functionRegistry
```

***

#### initialize

#### fallback

Invoked when called function does not exist in the contract

```solidity
fallback(bytes data_) external returns (bytes)
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs-v4.venus.io/technical-reference/reference-governance/omnichain-executor-owner.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
