chainpeek: List a wallet's live token approvals and get revoke transactions. For tokens already pulled out use check_wallet_drain; for one allowance use get_allowance. Returns the live ERC-20 and Permit2 allowances of ⟨32 unchanged words⟩ latest 6,000 blocks, Permit2, and `spenders`.Input: `chain`, `wallet`, optional `tokens`, `spenders`, `lookback_blocks` and `stale_days`.High: unlimited to a key-controlled account.

⟨6 unchanged words⟩ address poisoning: lookalikes in the sender's history. For balance, gas and blacklist checks too use transfer_preflight; for OFAC use check_sanctions.
Added "check_text_for_secrets" (25 tools before, 26 now)
utilpeek: scan a text for leaked API keys, tokens, private keys and seed phrases before it is posted — utilpeek: Scan text for leaked secrets: API keys, tokens, private keys and seed phrases. Returns every API key, token, private key or BIP-39 seed phrase in a text (AWS, GitHub, GitLab, Stripe, Slack, Google, OpenAI and other sk- keys, Hugging Face, npm, PyPI, SendGrid, Telegram, PEM and hex keys, JWTs, URL passwords), each with type, line, column, offset, confidence and a redacted preview. Input: `text`. The secret itself is never returned: only its type, position and a redacted preview (a vendor prefix and at most 4 characters at each end; a seed phrase only its word count). Pattern-based: a…
Added "get_verification_code", "get_wallet_counterparties" and "token_verdict" (22 tools before, 25 now)
dnspeek: read the one-time code or verification link from an email; the email body is never returned — dnspeek: Get the verification code or magic link from an email without the email body. Returns the one-time code(s) and verification link(s) from a raw email or text, the sender domain, SPF/DKIM/DMARC results from its Authentication-Results header and the stated expiry; never the email body. Input: `email`. The subject and other headers are never returned either: only short tokens cut by fixed patterns, so text hidden in a phishing mail cannot reach the caller's model; no model, nothing fetched; authentication results are read as given, not verified; a mail with no code is a normal answer and…
chainpeek: who does a wallet transact with? Top counterparties by transfers and USD volume, 1-90 days — chainpeek: List a wallet's top counterparties: who an address sends to and receives from, by count and volume. Returns who `address` transacts with over the latest `days` days (1-90; default 30) of ERC-20 transfers: `by_count` and `by_volume_usd` (25 each) with in/out counts, first/last seen, stablecoin USD volume, per-token amounts and `is_contract` (top 20); plus `tokens`, `summary` and `window`. Input: `chain`, `address` and optional `days`. A pre-send or due-diligence check: who an address deals with, not who it is (no labels). ERC-20 only. At most 1,000 transfers a direction: a busy addr…
Added "audit_token_approvals", "check_address_poisoning" and "check_wallet_drain" (19 tools before, 22 now)
chainpeek: list a wallet's live token approvals (ERC-20 and Permit2) with revoke transactions — chainpeek: List a wallet's live token approvals and get revoke transactions. Returns the live ERC-20 and Permit2 allowances of `wallet`: amount, `unlimited`, spender code (key-controlled, contract, new contract), newest approval and pull, `stale`, flags with evidence, and `revoke`, the unsigned transaction that sets it to 0. Candidates: approval events in the latest 6,000 blocks, Permit2, and `spenders`. Input: `chain`, `wallet`, optional `tokens`, `spenders`, `lookback_blocks` and `stale_days`. High: unlimited to a key-controlled account. Medium: limited to one, or unlimited to a contract wi…
chainpeek: check a transfer recipient for address poisoning on Base, Ethereum or Robinhood Chain — chainpeek: Check a transfer recipient for address poisoning: lookalikes in the sender's history. Returns a `risk` (high | medium | low) for paying `to`: reads `from`'s transfers of one token (default USDC) over the last 2,000 blocks and finds addresses with `to`'s first 4 and last 4 hex characters; each reason carries its evidence (tx hash, block, amount, direction). Input: `chain`, `from` and `to`, optional `token`, `contacts`, `lookback_blocks` and `dust_threshold`. High: `to` was never paid and imitates an address `from` paid or a contact, or appears only in zero-value or dust transfers. M…

Added "check_token_safety" (18 tools before, 19 now)
chainpeek: token safety check for an ERC-20 on Base or Ethereum: honeypot, tax and contract risk in one verdict — chainpeek: Use when an agent must decide whether an ERC-20 token on Base or Ethereum is safe to buy or interact with. Returns one verdict (high_risk, caution, no_major_flags_found or unknown) with reasons and a summary for an ERC-20: a simulated buy and sell-back (honeypot, measured buy, sell and transfer tax, pool, revert reason) plus contract flags (upgrade control, mint, blacklist, fee setters, pause, verification). Input: `address` and optional `chain`. Automated and heuristic, not an audit: no_major_flags_found is not proof of safety. The verdict rules are fixed and listed in the OpenAPI…

chainpeek: honeypot check, can this token be sold? Simulated buy and sell with tax on Base or Ethereum — chainpeek: Honeypot check: can this token be sold? Simulated buy and sell with tax. Returns a simulated buy and sell-back of an ERC-20 on Base or Ethereum (Uniswap V2/V3, Aerodrome): `honeypot` (true, false or "unknown"), can_buy, can_sell, buy, sell and transfer tax measured from real balances, venue, pool, liquidity and the decoded revert reason. Read-only: no deploy, no gas, no wallet. Input: `token`, optional `chain` and `amount_usd`. Heuristic, not an audit: sells blocked after a delay, for some wallets or by an owner-toggled blacklist can pass; a token with no pool is honeypot "unknown"…
