-DID methods are expected to provide [standards-compliant methods of DID and DID Document ("DIDDoc") production](https://w3c.github.io/did-core/#production-and-consumption). The **cheqd DID Resolver** is designed to implement the [W3C DID *Resolution* specification](https://w3c-ccg.github.io/did-resolution/) for [`did:cheqd`](https://docs.cheqd.io/identity/architecture/adr-list/adr-001-cheqd-did-method) method.

This means the `useTls` property would need to be set to `false`, unless you're otherwise using a load balancer that provides TLS connections to the gRPC port.
