# NameWrapper docs

The NameWrapper wraps ENS names, adding new functionality to them:

 - Makes all ENS names at any level into ERC1155 tokens.
 - Supports 'emancipating' names by allowing the owner of a parent name to revoke control over subdomains.
 - Supports 'locking' names by allowing the owner of a name to revoke control over changes in resolver, creation of subdomains, and other parameters.
 - Wrapped names can expire; a name that is emancipated or locked has a built in expiration at which the name (and that status) expires.
 - UIs and Smart Contracts can check the status of a name with a single function call, allowing them to ensure security guarantees are upheld.
 - .eth names can be registered and renewed via the wrapper, removing any need to wrap names separately after registration.
 - Owners of names can create wrapped subdomains directly, without having to register-then-wrap.

## Glossary of terms

- Wrap - Transfers ownership of the ENS name to the Name Wrapper. The wrapper then issues an ERC1155 token for the name.
- Unwrap - Reverses the wrap process and transfers the name to an address of the token owner's choice.
- Fuse - The term for a flag that can be set irreversibly until expiry. Fuses can do many things, including controlling permissions for the name itself.
- Emancipation - The process of the owner of a parent name revoking its control over a subname.
- Locking - The process of the owner of a name revoking some level of control over its own name.
- Owner-controlled fuses - Fuses that can be burned by the owner of a name or the owner of the parent name if the name is not emancipated.
