AI Contract Explainer (NLP)

Purpose

AI Contract Explainer adalah modul NLP yang menerjemahkan data teknis smart contract menjadi penjelasan bahasa manusia yang mudah dipahami user, sebelum transaksi ditandatangani.

Prinsip utama:

Explain, not execute

Read-only, non-custodial

Deterministic + explainable


---

Position in Architecture

User Action
   ↓
Transaction Builder
   ↓
Contract Decoder (ABI / Bytecode)
   ↓
AI Contract Explainer (NLP)
   ↓
Human-readable Explanation
   ↓
User Confirmation

Modul ini tidak memiliki akses ke private key dan tidak dapat mengubah transaksi.


---

Inputs

AI Contract Explainer menerima:

Contract address

Chain ID

Function selector

Decoded parameters

Value (ETH / token)


Contoh input:

{
  "contract": "0xABC...",
  "method": "approve(address,uint256)",
  "params": {
    "spender": "0xDEF...",
    "amount": "115792089237316195423570985008687907853269984665640564039457"
  }
}


---

Core Output

Output berupa ringkasan natural language + flags:

{
  "summary": "You are giving this contract unlimited access to your tokens.",
  "riskLevel": "HIGH",
  "flags": [
    "UNLIMITED_APPROVAL",
    "EXTERNAL_CONTRACT"
  ]
}


---

NLP Strategy (QVAC-style)

Phase 1 — Deterministic Templates

Rule-based detection

ABI pattern matching

Known risky functions


Phase 2 — Hybrid NLP

Template + LLM (local / distilled)

Contextual explanations

Parameter magnitude awareness


Phase 3 — Verified AI

Signed explanation models

Optional ZK-proofed inference

Governance-approved updates


---

Risk Patterns Detected

Unlimited token approvals

Proxy / upgradeable contracts

Self-destruct functions

Delegatecall usage

Suspicious fallback logic


---

Example Explanations

ERC20 Approve (Unlimited)

> ⚠️ This transaction allows another contract to spend all of your tokens, now and in the future.


Swap

> 🔄 You are swapping 1.2 ETH for tokens at a variable price. Final amount may change.


NFT Mint

> 🎨 You are minting an NFT. This action cannot be reversed.


---

Security Guarantees

No signing capability

No transaction mutation

Fully auditable logic

Optional offline inference


---

UX Integration

Shown before biometric / PIN confirmation

Requires explicit user acknowledgment

High-risk → extra confirmation step


---

Roadmap Integration

Phase 2: LLM-assisted explanations

Phase 3: Multilingual explanations

Phase 4: Community-verified explanation packs


---

Why This Matters

Most hacks succeed because users do not understand what they sign.

AI Contract Explainer turns:

> Blind signing ❌


into:

> Informed consent ✅
