Channel hand-off ships Q4 2026 · public API + SDKs Q3 2026
Channel Continuity API
Voice · Chat · Email · WhatsApp.
One evidence chain across every channel. Once chat ships (Q4 2026), you'll hand off a conversation from voice to WhatsApp without breaking the attestation context — every linked receipt will trace back to the same Merkle root.

}Why one chain matters
Chat is the bigger market
AI chat traffic is roughly 10× voice. Same Article 50 obligations, same evidence requirements.
Hand-offs are common
Voice → email follow-up, chat → WhatsApp, agent → human. Each transition is a compliance event.
Auditors ask one question
“Show me everything this caller saw.” One receipt tree, one export, every channel.
One chain. Every channel.
