# FAQ * Q: Why a server wallet when mobile wallets exist? * A: Automation. It lets CI, scripts, and AI agents complete the same flows without a human, while staying standards‑compliant. * Q: How does multi‑tenancy work? * A: Each request is scoped by JWT `sub`. Data (DIDs, VCs, flows) is isolated per `sub`. * Q: Can I use did:web without owning a domain? * A: For production, you must control the domain. For local testing, you can use hosts/port forwarding, but the DID will encode your chosen host. * Q: Why does presentation confirmation require the full VC? * A: The verifier needs the credential payload to validate; the id alone isn’t sufficient. * Q: Where are credentials filtered by network? * A: `GET /credentials` inspects the DID in each VC id and filters by `mainnet` or `testnet` accordingly. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
