Sigui Protocol Security Skill 🛡️
Sigui is a multi-chain AI security oracle that evaluates blockchain transactions before
they execute, using a native Spatio-Temporal Transformer (Trustformer/T-GAT) to detect
coordinated attacks in real time.
[!IMPORTANT]
This skill requires a real Sigui API endpoint for production use.
Set SIGUI_API_URL to your node URL. Without it, the script exits safely (fail-closed).
A --demo flag is available for testing, but MUST NOT be used to authorize real funds.
🔐 Security Model
This skill is designed with a fail-closed security policy:
| Situation | Behavior |
|---|
| No API URL configured | ❌ Exits with error — does NOT simulate |
| API unreachable | ❌ Exits with error — does NOT simulate |
| ALLOW verdict | ⏸️ Pauses and asks for explicit user confirmation |
| BLOCK verdict | 🚫 Immediately returns exit code 1 |
| ESCALATE verdict | 🔍 Requests deep analysis with --escalate |
--demo flag set | ⚠️ Shows prominent warning — heuristic only |
🧠 Agent Instructions (Chain of Thought)
When a user explicitly asks to evaluate a specific transaction, follow these steps:
Step 1 — Extract Parameters
Identify from the user's message:
amount: transaction value (convert to USDC equivalent if needed)
destination: the target wallet or contract address
chain: the blockchain (default arc)
action: the action type (transfer, approve, swap, bridge, mint)
If any required parameter is missing, ask the user before running the evaluation.
Step 2 — Ask for Explicit Confirmation Before Running
Before executing the script, show the user:
"I'm about to evaluate this transaction with the Sigui security oracle:
- Amount: {amount} USDC
- Destination: {destination}
- Chain: {chain}
- Action: {action}
Shall I proceed?"
Step 3 — Run the Evaluation
python ~/.openclaw/workspace/skills/sigui-security/evaluate.py \
--amount {amount} \
--destination {destination} \
--action {action} \
--chain {chain}
Step 4 — Interpret the Exit Code
| Exit Code | Verdict | Agent Action |
|---|
0 | ALLOW | Ask user: "Sigui approves. Do you confirm the transaction?" Only proceed if user says yes. |
1 | BLOCK | 🚫 ABORT. Tell the user the threat detected. Do NOT proceed. |
2 | ESCALATE | Ask user if they want deep analysis, then re-run with --escalate. |
3 | Error | Report the error. Do NOT proceed with the transaction. |
Step 5 — After ALLOW: Require User Confirmation
Re-run with --confirmed only after the user explicitly says yes:
python evaluate.py --amount {amount} --destination {destination} \
--action {action} --chain {chain} --confirmed
🛠️ Setup
1. Install Dependencies (automatic)
The skill auto-installs sigui-sdk when first run. Or run manually:
bash ~/.openclaw/workspace/skills/sigui-security/install.sh
2. Configure Your Sigui Endpoint (required for production)
export SIGUI_API_URL="https://your-sigui-node.com"
export SIGUI_CHAIN="arc"
export OPENCLAW_AGENT_ID="my_agent"
3. Test in Demo Mode (non-authoritative)
python evaluate.py --amount 50 --destination 0xYourAddress --demo
⚠️ Demo mode output is a local heuristic simulation, NOT an oracle evaluation.
Never use demo results to authorize transactions.
📊 Verdict Table
| Verdict | Risk Score | Meaning |
|---|
ALLOW | 0.0–0.35 | Transaction appears safe — await user confirmation |
ALLOW_WITH_CAP | 0.35–0.55 | Safe up to spending cap — await user confirmation |
ESCALATE | 0.55–0.80 | Ambiguous — request deep analysis before deciding |
BLOCK | 0.80–1.0 | Threat detected — do NOT proceed |
Safety Score = (1 - risk_score) × 1000. Higher = safer.
🛡️ Threats Detected
| Attack | Description |
|---|
| Drain Star | Orchestrator draining multiple wallets simultaneously |
| Mixing Chain | Layered hops through mixers to obscure fund origin |
| Sybil Swarm | Fake-identity cluster attacking governance or airdrops |
| Flash Loan Exploit | Oracle price manipulation within one atomic block |
| Honeypot Contract | Buy-enabled, sell-disabled token trap |
| Rug Pull | Liquidity removal by deployer |
| Phishing Signature | Malicious eth_sign / permit approval |
