Messaging
1:1, channels, threads, reactions. Encrypted in transit and at rest. Post-quantum upgrade path ready.
DIDComm v2Vilko is encrypted team messaging built on DIDComm v2. Every identity is cryptographically verified. Custody keys live on your device. Sovereign deployment is a checkbox, not a sales cycle.
Messaging, calls, calendar, tasks, and files — built on a single encrypted protocol. One app for regulated teams that can't risk a breach.

ComplianceClient-held keys protect your locked tenant data. The relay forwards ciphertext it cannot decrypt, and the directory only knows which email maps to which public DID. Our current cloud service can access decrypted data while your tenant is open.
Your passkey derives the keys that unlock your account, and those never leave your device — we cannot unlock your data without you. Messages encrypt before they hit the wire with X25519 + XC20P.
Our relay stores encrypted blobs and forwards them. It cannot read content, resolve senders, or reconstruct history. It is protocol_coordinate_mediation, nothing more.
Email maps to did:peer. Verifiable credentials back the “Verified” badge. Federate it, self-host it, or run it inside your own sovereign cloud.
We show our work. Where Slack, Teams, and Signal differ from us — and why a regulated team can't just “use Signal for work.”
