# Collision Management

When the same Web3 domain exists in multiple blockchains or namespaces, a collision occurs.

NOTO includes a patent-pending scoring algorithm that provides guidance on the status of each domain to help pick the most relevant option.

Partners can customize how the domain scoring works. Among other things, you can raise the priority of certain providers or create custom rules and exceptions:

* Add Exception -> type the Domain or TLD *(e.g. ".com" is a TLD )* and choose your preferred Namespace for it and -> Click Save.
