Wolfë VACP

Voice-Activated Compliance Promise

Structural Certainty for RWAs

Inspiration

2024–2025 saw over $650 M in liquidations because off-chain promises could be forged, coerced, or sold.
Wolfë GRC V6 was built to make on-chain promises immutable.
But even a wallet signature isn’t enough for institutional capital.
True structural certainty requires binding the promise to the human voice — the only truly non-transferable biometric.
Wolfë VACP is that missing layer.

What it does

Users must speak this exact GRC affirmation out loud:
“I promise this asset is non-toxic and compliant with Wolfë’s immutable GRC V6 standard.”

ElevenLabs captures the real-time voiceprint and transcribes
Gemini 1.5 Pro (Vertex AI) instantly scores:
– Semantic compliance (did they say the exact phrase?)
– Coercion / confidence risk (tone & certainty)
Only if both scores ≥ 0.85 does the user mint a non-transferable Wolfë Belonging SBT
Voice hash + AI scores are stored forever in the immutable PDA ledger (Program ID 8x8777SCvUmtYY2pan3siGcGiqYQM7zPyAsfEvzQWP2q — upgrade authority already burned)

This is the highest-assurance identity primitive ever shipped on Solana.

How we built it

Re-used existing immutable Wolfë GRC V6 Anchor program (zero Rust changes)
Next.js 14 App Router + Tailwind + Solana Wallet Adapter
Real ElevenLabs JS SDK → STT + voice hashing
Google Vertex AI → Gemini 1.5 Pro for semantic & coercion scoring
Secure server-side Next.js API routes (keys never exposed)
Deployed on Vercel in under 48 hours

Challenges we ran into

Forcing Gemini 1.5 Pro to return clean boolean/number outputs (solved with strict prompting)
Deterministic voice hashing for on-chain storage
Keeping ElevenLabs & Vertex keys server-side while preserving snappy UX

Accomplishments that we're proud of

First-ever voice-gated SBT mint on Solana
Real (not mocked) ElevenLabs + Gemini integration shipped in 48 hours
Live immutable program already on Devnet with upgrade authority burned
Zero-token, pure public-good primitive ready for institutional audit

What we learned

Voice is the final frontier of non-transferable identity.
Gemini 1.5 Pro can reliably detect coercion risk from transcript alone when prompted correctly.
Solana’s PDA model is the perfect place to bind biometric proofs forever.
