# Resolving NFDs

## Off-Chain

NFDomains provides a public [REST API](https://api-docs.nf.domains/quick-start) for integrators and the community to utilize. It provides read-only methods, as well as methods that modify the NFD contract states (minting / claiming / updating / selling, etc.) which require the caller to sign returned transactions.

The UI for NFDomains uses the very same public API.

## On-Chain

NFDs can be resolved entirely on-chain. See the [On-Chain Reference](https://api-docs.nf.domains/reference/on-chain-reference/name-and-address-lookup) section of the API docs.
