# XVSProxyOFTDest

## XVSProxyOFTDest

[`XVSProxyOFTDest` at token-bridge v2.7.0](https://github.com/VenusProtocol/token-bridge/blob/v2.7.0/contracts/Bridge/XVSProxyOFTDest.sol) is the non-upgradeable bridge used on destination networks. It burns the destination-chain XVS token on outbound transfers and mints it on inbound transfers. Minting is additionally bounded by the token's per-minter cap; this contract does not use the BNB source bridge's locked-supply accounting.

XVSProxyOFTDest contract builds upon the functionality of its parent contract, BaseXVSProxyOFT, and focuses on managing token transfers to the destination chain. It provides functions to check eligibility and perform the actual token transfers while maintaining strict access controls and pausing mechanisms.

## Solidity API

#### dropFailedMessage

Clear failed messages from the storage.

```solidity
function dropFailedMessage(uint16 srcChainId_, bytes srcAddress_, uint64 nonce_) external
```

**Parameters**

| Name         | Type   | Description                                          |
| ------------ | ------ | ---------------------------------------------------- |
| srcChainId\_ | uint16 | Chain id of source                                   |
| srcAddress\_ | bytes  | Address of source followed by current bridge address |
| nonce\_      | uint64 | Nonce\_ of the transaction                           |

**📅 Events**

* Emits DropFailedMessage on clearance of failed message.

**⛔️ Access Requirements**

* Only owner

***

#### circulatingSupply

Returns the total circulating supply of the token on the destination chain i.e (total supply).

```solidity
function circulatingSupply() public view returns (uint256)
```

**Return Values**

| Name | Type    | Description                                                     |
| ---- | ------- | --------------------------------------------------------------- |
| \[0] | uint256 | total circulating supply of the token on the destination chain. |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs-v4.venus.io/technical-reference/reference-xvs-bridge/xvsproxyoftdest.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
