  • evaluate_trade Pre-trade risk check for a proposed trade. Call this BEFORE executing any trade and treat a "deny" decision as a hard stop. Evaluated at a fixed Tier 1 ceiling ($5,000 notional). For higher limits, use `evaluate_trade_paid` (Tier 2, $25,000) which settles an x402 payment on-chain.
  • evaluate_trade_paid Pre-trade risk check gated by an x402 payment. Evaluated as COLR Tier 2: $25,000 notional ceiling, 10/25 per-minute rate limits. No COLR holdings are required — the on-chain payment is the credential. FLOW ---- 1. Call WITHOUT payment_proof → the tool returns a `PaymentRequiredOutput` describing
  • check_token_safety Honeypot / contract safety check for any ERC-20 token.

When severity=danger, the next `evaluate_trade` for the same contract is automatically denied regardless of any ot
  • simulate_balance Simulate a wallet's ERC-20 balance after a hypothetical trade using eth_call state override. Read-only: no transaction is ever sent.
  • get_supported_assets List every asset in the guardrail's official Robinhood Chain registry, with its canonical contract address.
  • verify_audit_trail Verify the tamper-evident audit trail for a wallet's past guardrail decisions.
