Smart contract security screening for Base. Check any contract or token for risk before interacting with it: Solidity source verification, upgradeable proxies and admin or mint powers, holder concentration, dangerous selectors, and B20 issuer powers. It surfaces the usual rug pull and scam indicators. The free tool needs no wallet and no API key; the paid Flash Audit (3.49 USDC over x402) returns a report with an anchored SHA-256. Payment is the only gate.
13 free Base tools: address labels, tx explain, balances, receipts, gas, logs, bytecode.
Version 2.8.0. HyperNatt Terminal: liquidation radar, Hyperliquid execution context and Li.Fi cross-chain swap for AI agents. BTC ETH SOL BNB XRP HYPE ZEC. Before an order: estimate depth, VWAP, spread and fees for its size. Between checks: compare liquidity and costs with the previous baseline. After execution: reconcile supplied fills. Read-only data, no custody or order submission. 6 tools, v2.8.0; call get_agent_manifest first. Radar and each execution-context call cost 0.001 USDC via x402 Base/Solana or eligible credits; manifest and MCP swap quote are free (on-chain swap fees apply). Daily MCP trial: one free call per paid tool and per token per client each UTC day. Four tools x seven tokens = up to 28 independent trials; then 0.001 USDC per call. Read trial_policy_v2 and free_tier_status_v1 on the same MCP connection for current availability. A zero daily_cap is the separate credit pool, not the intro allowance.
