Declared skills 6
- Check token safety
Honeypot and contract safety check for any ERC-20 token. Returns severity (safe, warn, danger) and the specific risk factors found, using bytecode analysis and a live sell simulation. CRITICAL: when severity=danger, the next evaluate_trade call for the same contract is automatically denied. Use before trading unknown tokens or tokens absent from the official registry. If the response contains an 'error' key, the check failed — do not assume 'safe'.
- Evaluate a trade
Pre-trade risk check. Returns allow, warn, or deny, with every reason attached and a tamper-evident audit hash. Checks tier limits, oracle/V4 price source, slippage, market hours, cluster rate limits, and daily loss. If check_token_safety returned severity=danger for the contract, this skill automatically returns deny regardless of other checks. If the response contains an 'error' key, no verdict was produced — treat as a hard stop and do not execute the trade.
- Evaluate a trade (x402 paid, Tier 2)
Same as evaluate_trade but gated by an x402 payment. Evaluated as Tier 2 ($25,000 ceiling, 10/25 per-minute rate limits). Call WITHOUT payment_proof to receive a PaymentRequiredOutput challenge; settle on-chain; retry with the proof to receive a full verdict with tier=2. No COLR holdings are required — the on-chain payment is the credential. If the response contains an 'error' key, no verdict was produced — treat as a hard stop.
- List supported assets
The official Robinhood Chain asset registry with canonical contract addresses. Resolve a symbol correctly before calling evaluate_trade.
- Simulate a wallet balance
Read-only state-override simulation of an ERC-20 balance after a hypothetical trade. No transaction is sent. If the response contains an 'error' key, the simulation failed.
- Verify audit trail
Recompute every past decision's SHA-256 hash and verify the hash-chain links. Proves no decision was edited, deleted, or reordered. If the response contains an 'error' key, verification could not run.
