Resolvr.io is a nostr client that supports NIP-57 lightning zaps. Users who have specified a lightning address in their profile settings (previously on another nostr client or on resolvr.io) can use a browser extension like alby to send and receive zap payouts for bounties. Resolvr.io doesn't hold bitcoin at any point.

As for DLCs, that's on the roadmap and is heavy WIP. DLCs require a desktop app to manage and negotiate the on-chain contract, and to send and receive associated bitcoin. So, the manager app will feature a non-custodial wallet.

The Resolvr Project exists to create tools for sovereign individuals and communities. At no point will we ever make users custody funds with us.

Thanks!
