C. Resolver Contracts

• Function of Resolver Contracts:

Resolver contracts are a core component of the UNS smart contract architecture. They are responsible for translating a registered UNS name into the corresponding wallet addresses or other data linked to the name. When a user enters a name like "user.uns," the resolver contract fetches the associated address and provides it for transactions.

The resolver is designed to be flexible, allowing users to update their mapped addresses without changing the ownership of the UNS name itself. This decouples identity management from the underlying addresses, providing users with greater control over their blockchain interactions.

• Cross-Chain Compatibility:

Each resolver contract is deployed on its respective blockchain, tailored to interact with that network’s data structures and protocols. This design ensures that the resolution of a UNS name to an address is efficient and cost-effective on each blockchain.

The resolver contracts are also designed to support interoperability, meaning that updates made on one chain can be communicated across other chains using cross-chain communication methods. This ensures consistency in name resolution across all networks where the UNS name is active.
