BTC assets and Rooch assets issues

Q: Can the status or content of the BTC asset warehouse be changed after it becomes a Rooch asset? For example, if it can be changed by adding another layer, do we also need to consider converting it into the original asset mode when returning?

A: Turn the BTC asset into a Move Object, and you can write status into it through dynamic fields.

Q: Asset processing, for example, if a BTC asset comes over and we want to do more processing on the asset, such as adding some tags, does it require additional processing when the asset returns to BTC?

A: Regarding this aspect, the documentation on asset leap (opens in a new tab) has detailed introduction.
