Wolfë ErnieScore

Fine-tuned ERNIE 4.5 (Unsloth) + PaddleOCR-VL creates the first multi-modal AI gate for RWA compliance on Solana — only verified promises mint.

Comment

Inspiration

2024–2025 saw over $650 M in RWA liquidations because off-chain promises and paper documents could be forged, coerced, or simply lost.
Wolfë GRC V6 was built to make on-chain promises immutable on Solana.
But even a wallet signature isn’t enough for institutional capital.
True structural certainty requires binding the promise to verifiable documents and AI-vetted semantics — the missing multi-modal layer.
Wolfë ErnieScore is that layer.

What it does

Users must prove compliance in two non-transferable steps before minting a Wolfë Belonging SBT:

  1. Upload an IP license / legal filing → PaddleOCR-VL extracts and validates structured GRC metadata (jurisdiction, expiry, etc.)
  2. Submit their exact digital promise → a custom ERNIE 4.5 model fine-tuned with Unsloth scores semantic risk and compliance (0–1)
    Only if OCR passes AND ErnieScore ≥ 0.90 does the immutable Wolfë GRC V6 program (Program ID 8x8777SCvUmtYY2pan3siGcGiqYQM7zPyAsfEvzQWP2q) mint the SBT and write both results into the PDA ledger forever.
    This is the highest-assurance onboarding primitive ever shipped for real-world assets on Solana.

How we built it

  • Re-used existing immutable Wolfë GRC V6 Anchor program (zero Rust changes, upgrade authority burned)
  • Next.js 14 App Router + Tailwind + @solana/wallet-adapter-react
  • Fine-tuned ERNIE 4.5 using Unsloth on a curated dataset of high-risk vs. compliant legal promises
  • PaddleOCR-VL for document ingestion and structured metadata extraction
  • Secure server-side API routes calling Hugging Face Inference Endpoints (keys never exposed)
  • Deployed on Vercel in under 72 hours

Challenges we ran into

  • Forcing ERNIE 4.5 to output a clean 0–1 compliance score (solved with Unsloth + strict system prompting)
  • Deterministic document hashing for on-chain storage from PaddleOCR-VL output
  • Keeping latency under 3 seconds while preserving server-side key security

Accomplishments that we're proud of

  • First-ever multi-modal AI-gated SBT mint on Solana (document + semantic promise)
  • Live fine-tuned ERNIE 4.5 model specialized for GRC risk scoring (Unsloth)
  • Zero-token, pure public-good primitive ready for institutional audit
  • Fully immutable on-chain program already on Devnet with upgrade authority burned

What we learned

Fine-tuned ERNIE 4.5 dramatically outperforms base models at detecting legal dilution and coercion in financial promises.
PaddleOCR-VL + ERNIE creates a verifiable chain-of-custody from paper to on-chain record.
Solana’s PDA model is the perfect place to bind multi-modal AI proofs forever.

What's next for Wolfë ErnieScore

  • Mainnet immutable deploy (Solana Foundation Milestone 1)
  • Zellic / OtterSec audit of the fine-tuned model integration (Milestone 2)
  • Integration with Ondo, Credibly, Figure, and other RWA issuers
  • Open-source the ErnieScore fine-tune dataset and inference template for the entire Solana ecosystem

Structural Certainty now has documents and a voice.
We just gave it both.
