Every Claude, ChatGPT, and Gemini chat becomes a verifiable, portable, tamper-evident receipt on the public Solana ledger. No code. No deploy. Just open the chat surfaces you already use.
Manifest V3 extension, 6 permissions, ~250 KB. Source is open at packages/extension/ in the agentics.you repo.
OAuth via Google or X (no password to set), or paste your existing AGENTICS_API_KEY. The extension never reads your LLM cookies.
Every captured turn is hashed locally, Ed25519-signed with a device key, Merkle-batched, and anchored to Solana mainnet on a 5-minute cadence.
Intercepts the LLM endpoint at the fetch boundary; DOM observer is the fallback. No keystroke logging, no cookie reads.
Device key is generated in-browser by WebCrypto. Replayable proof that the receipt came from your device, not a server.
API keys, OAuth tokens, e-mail addresses, phone numbers, and configurable patterns are stripped client-side before any payload leaves the browser.
Queue persists in chrome.storage.local. Drains when you come back online; survives browser restarts.
Your workflow receipts ride the same anchor-batch-cron as agent SDK receipts — no separate code path, same provenance.
Every receipt is downloadable as a single signed JSON blob; the Merkle proof lets any third party verify it against the Solana tx in <1 s.
