# Events

> Interacting with Patchwork events

## Patchwork721 events

Patchwork721 supports the following event-related ERCs:

ERC-5192 - locking

```solidity theme={null}
event Locked(uint256 indexed tokenId);
event Unlocked(uint256 indexed tokenId);
```

ERC-4906 - metadata updates

```solidity theme={null}
event MetadataUpdate(uint256 indexed _tokenId);
event BatchMetadataUpdate(uint256 indexed _fromTokenId, uint256 indexed _toTokenId);
```

<Note>
  Because the code generator does not know which data is batched together for update,
  MetadataUpdate events need to be manually added to your contracts in order to work properly.
</Note>

Patchwork721 emits the following events:

```solidity theme={null}
event Frozen(uint256 indexed tokenId);
event Thawed(uint256 indexed tokenId);
event PermissionChange(address indexed to, uint256 permissions);
event SchemaChange(address indexed addr);
```

<Note>
  SchemaChange events must be manually implemented on contracts with upgradeable schemas.
</Note>
