• Token Risk

  Pre-trade safety score for any Base token — Pass a token contract address and get a risk score + flags (ERC-20 conformance, ownership renounce, upgradeable proxy) computed live from Base. Built for trading bots and agents that vet tokens before buying. Required input: address. Priced $0.03 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.

• Pre Trade Gate

  One call before you trade — GO / HOLD / STOP — The single call an agent makes before touching a Base token: token risk + sellability (honeypot/tax) + route/price-impact + deployer reputation, collapsed into one GO/HOLD/STOP verdict with an auditable receipt. Cheaper than the four checks à la carte. This is the tool to bind first. Required input: address. Priced $0.10 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet o

• Sign Guard

  Should the agent sign THIS calldata? GO/HOLD/STOP — The check before the riskiest moment — signing. Decodes raw unsigned calldata (approve / permit / transfer / setApprovalForAll), shows the exact intent (who gets power over what, and whether it's UNLIMITED), and screens the destination + spender for OFAC sanctions and dangerous owner powers, in one GO/HOLD/STOP verdict + receipt. No simulation needed — pure decode + onchain risk. Catches the unlimited-approval drain vector before it's signed. R

• Spend Audit

  Which apps/agents can pull funds from this Base wallet? — Base Account spend permissions let an app or agent spend a scoped, recurring allowance from a wallet — the primitive behind autonomous agent payments on Base. This reconstructs a wallet's ACTIVE spend permissions from onchain approve/revoke events and flags the dangerous ones: unlimited allowance, no expiry, unrecognized spender. The Base-native, agent-era drain check that ERC-20 approval tools can't see. Required input: wallet. Priced $0

• Agent Wallet Audit

  Every way this wallet can be drained without a fresh signature — The complete fund-movement authority on a Base wallet in one call: ERC-20 approvals (a spender you approved can pull the token) PLUS Base Account spend permissions (the agent-era scoped recurring allowance) — one drain-surface verdict with the ERC-20 revoke queue to act on. Approval tools miss the spend permissions; spend-permission tools miss the approvals. The only combined check for agent wallets that must know their whole expos

• Wallet Delegation

  Is this EOA secretly running someone else's code? — Since Pectra an EOA can carry EIP-7702 delegated code (the 0xef0100 designator): every call to the wallet executes the DELEGATE's contract with the wallet's funds — a malicious delegate is total takeover, invisible to approval tools. Reads the designator, resolves the delegate and verdicts it: not_delegated / delegated_known (Coinbase's EOA→SmartWallet path) / delegated_unknown (🚨) / smart_contract. The drain surface no other Base tool checks.

• Commerce Escrow

  Auth/capture payment reconciliation on Base — First tooling for Base's Commerce Payments protocol (AuthCaptureEscrow): reconciles two-phase auth/capture payments — in escrow, captured, charged, voided, refunded, or payer-RECLAIMABLE because the operator missed the capture window. Filter by payment= (infoHash), payer=, receiver= or operator=, or omit everything for the network feed. The order-reconciliation read merchants and agents need before trusting onchain commerce. Priced $0.04 per call ove

• Commerce Operator Audit

  Should you trust this Commerce Payments operator? — Commerce Payments flows are DRIVEN by an operator — it authorizes escrow, captures for merchants and takes the fees. This audits one before you rely on it: 90-day volumes, fees taken, capture-vs-reclaim record (missed capture windows = merchants left unpaid), distinct payers and merchants. verdict: healthy_operator / mixed / sloppy_operator / no_activity. No other tool reads this new Base commerce protocol. Required input: operator. Priced $0.0

• Morpho Health

  Is this Morpho lending position about to be liquidated? — First lending tooling in the catalog. Reads a Morpho Blue position on Base (the largest lending venue on Base) and returns its liquidation health in one call: health factor, current vs liquidation LTV, and the exact collateral price drop that triggers liquidation. Built for borrowing agents and treasuries that need to know how close they are before the market cuts them — Morpho's own API is deferred. Pass wallet= and optionally market= (d

• Morpho Vault

  Should you deposit into this MetaMorpho vault? — A MetaMorpho vault spreads your deposit across Morpho Blue markets — your real risk is WHERE the curator put it and WHO can move it. Reads the vault's live allocation (concentration, per-market collateral + liquidation LTV), idle share, performance fee, timelock, and control (curator/owner/guardian, and whether one address holds both). Returns a diversified / concentrated / control_risk verdict: the read before parking funds in a yield vault. vaul

• Morpho Liquidatable

  Which Base Morpho positions are liquidatable right now? — Built for liquidator / MEV searchers. Reconstructs the active borrower set on a Morpho Blue market from Borrow events, prices every position onchain in one multicall, and ranks them by liquidation health — flagging positions liquidatable NOW (health <= 1.0) and those one small move away, with the collateral price drop that tips each over. market= optional (defaults cbBTC/USDC), maxHealth= cutoff (default 1.1). Not financial advice. Priced

• Gas Payer

  Who pays this wallet's gas? Is it a sponsored smart account? — A smart account's gas can be paid by a PAYMASTER instead of the account itself — invisible to every 'does this wallet spend ETH' heuristic. Reads a wallet's UserOperationEvents across BOTH EntryPoints (v0.6 + v0.7): is it a smart account, its op count and success rate, and WHO sponsors its gas (self vs which paymaster, per-sponsor share). A fully-sponsored account is typically app- or agent-operated. wallet= required, days= optional

• Paymaster Check

  Should you trust this Base gas paymaster? — Given a paymaster address, audits whether it's a healthy, active gas sponsor. Reads its UserOperationEvents across both EntryPoints: sponsored op volume, distinct accounts served, success rate, total gas sponsored, and concentration (the share coming from its single busiest app). The read to run before integrating a paymaster (Coinbase / Pimlico / Alchemy / custom), or judging who funds a counterparty's gas. paymaster= required, days= optional (default

• Safe Check

  Real M-of-N multisig, or a 1-of-1 that just looks like one? — Multisig / treasury intelligence. Given an address: is it a Gnosis Safe, its owners and M-of-N threshold, version, activity, and — critically — its enabled MODULES. A module can move the Safe's funds via execTransactionFromModule with no owner signatures, so each one is an address with unilateral control. Returns a multisig / single_signer / has_modules verdict: the counterparty check before you trust funds to a multisig. address= req

• First Funder

  Where did this wallet's money originally come from? — Funding provenance in one call. Traces a Base wallet back to its EARLIEST transaction and resolves who first funded it: a recognized exchange/bridge (real on-ramp, lower risk), an anon EOA (possible sybil/burner — trace the cluster), or a contract. Returns the first funder, whether it's a contract or EOA, the initial value, and wallet age. The sybil/origin screen no other Base tool gives — the counterparty check before you transact. wallet= r

• Fresh Bridge

  Is this wallet's USDC freshly bridged, and from where? — Cross-chain inflow detection. Reads a wallet's recent USDC MINTS and correlates them with Circle CCTP receives to tell you whether its USDC is freshly bridged in (and from which source chain — Ethereum, Arbitrum, OP, Polygon, Solana…) vs natively issued. Freshly bridged capital is new money / a possible cross-chain hop — a real signal for trading and liquidation agents that no other Base tool surfaces. wallet= required, days= optional (def

• Safe To Send

  Is this address safe to send, approve or sign to? — Before your agent sends, approves or signs to an address: one GO/REVIEW/STOP verdict. Screens OFAC sanctions, Coinbase/Basename identity, wallet vs contract, how long the address has existed, and whether contract logic can be swapped AFTER you send. Every factor returns what it found and what it could not read — a check that did not run never reads as clean, so GO means everything material was actually screened. Not financial advice. Required i

• Address Trust

  Is this counterparty Coinbase-verified or an anon/sybil? — The 'who am I dealing with?' check for agents. Reads Coinbase's ONCHAIN verification (an EAS attestation by verifications.coinbase.eth) — meaning the address is tied to a KYC'd Coinbase account, the strongest sybil-resistance signal on Base — plus the address's Basename. Returns a verified/named/anonymous verdict + trust score. Pair with sign-guard/spend-audit for a full pre-transaction gate. Identity is a signal, not proof of honesty. R

• Basename Profile

  Full onchain identity behind a Basename or address — Resolves the complete Base identity behind an address or Basename: resolved address, avatar, description, website and social handles (X/Twitter, GitHub, Farcaster, Discord) read from Base's L2 Resolver text records. Lets an agent turn a counterparty address into a real profile — beyond just the name. Complements address-trust (verification) with the human context. Required input: name. Priced $0.02 per call over x402 on Base; send a prepaid x-

• Whale Flow

  Is size moving to the exits right now? — Flow, not snapshot: the largest transfers of a Base token in the last 24h, classified by whether whales are sending INTO DEX pools (sell pressure) or pulling OUT (accumulation) — a net sell-pressure read that decays in hours. Complements holder-forensics ('who could dump') with 'is anyone dumping now'. CDP-indexed events. Required input: address. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 fr

• Watchlist Diff

  What changed on my tokens since last check? — Retention in one call: pass up to 10 tokens to snapshot them and get a watchId; call again with that watchId to get only the DELTAS since last time — liquidity ±%, price ±%, became-honeypot, sell-tax spiked, liquidity pulled. The second call is worth more than the first. Built for agents holding positions that re-check daily. Priced $0.06 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per

• Address Intel

  Instant profile of any Base address — EOA vs contract, ETH + USDC balance, transaction count and activity level — straight from Base RPC. Useful for counterparty and wallet checks. Required input: address. Priced $0.02 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.

• Gas Oracle

  Live Base gas estimates — slow / normal / fast — Returns current Base gas fees (baseFee, maxPriorityFee) and three tiered suggestions (slow, normal, fast) in Gwei, derived live from the Base RPC. Built for agents that time or cost-estimate transactions. Priced $0.01 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.

• B20 Safety

  Can this Base-native (B20) token freeze or seize your funds? — Live — B20 is Base's native precompile token standard, and unlike ERC-20 a B20 issuer can freeze holders (Policy Registry) and even SEIZE your balance (burnBlocked) at the protocol level. This reads those powers — seizable, freezable, paused, rebase, uncapped-mint — into one hold/caution/avoid verdict, and separates a real tokenized stock from one merely wearing an equity ticker by reading the transfer-policy admin on chain, not a li

• B20 Gate

  One GO/HOLD/STOP before you touch a B20 token — The single call before trading a Base-native B20: seize (burnBlocked) + freeze (Policy Registry) + rebase + pause + uncapped-mint, collapsed into one GO/HOLD/STOP verdict with an auditable receipt. Pass wallet= to also check if YOUR address is already blocked on that token. The B20 tool to bind first. Required input: address.
