Wallet Profile ($0.03 — below the category-leading "wallet-intelligence" comparable WalletGuard's $0.05): profiles a Base wallet/contract address in one call — is-contract, first/last on-chain activity, outgoing tx count, native ETH + tracked ERC-20 balances (USDC/WETH/cbBTC/DAI), recent counterparties, known-label hits, a real working OFAC SDN sanctioned-address check (WalletGuard's own live sample ships this non-functional), and a concise risk summary. Fetched live from Base's public RPC +…

Legacy/supporting: monthly tool/token budget status, runway, warnings. Not the go-to — prefer Signal.

Audit a Hyperliquid wallet address you already know: every open perpetual position with side, size, leverage, unrealized PnL, liquidation price, and distance-to-liquidation percentage. Does not discover or rank wallets - Hyperliquid's public API has no leaderboard endpoint, so this only audits an address you supply. Paid in USDC on Base.

Verdix: call before an agent sends funds to an EVM address on Base. Returns safe/caution/danger with reasons from OFAC sanctions, scam/phishing lists, address-poisoning lookalikes, burn-address and contract/deployer checks; quick adds address age, standard/deep on-chain behaviour. "safe" is not a guarantee. Legacy route that sells 3 tiers (a default client buys quick); new integrations should call /risk/address/quick, /standard or /deep.

Keccak-256 of any string or hex payload - the hash Ethereum actually uses, which is NOT the same as SHA3-256. Needed for selectors, event topics, salts and CREATE2 addresses.
