Toll — coin, agent and pre-sign checks on Robinhood Chain

Check one token on Robinhood Chain from the chain itself: who is behind it and how it launched. On Robinhood Chain: where and when it launched, the maker (dev) and its launch record, snipers in the first 3 seconds, wallets the launch made exempt from tax (bundles), flagged wallets, what the maker holds and sold, burned supply, the curve or pool. Toll's findings are tallied as against / careful / clear. The answer's first line names the chain. Reads Robinhood Chain (4663).

LARP check: is there a real product behind a coin on Robinhood Chain? Toll reads the coin's own site, launch post and code README, lists each thing it says it offers, and checks every claim against the chain and against its working parts that Toll tries itself (app page, API, MCP server, x402 payments, Chrome extension, Telegram bot, public code). Answers the label (product found / partly found / not found / not read: what we could check, never a verdict), each claim with found / partly / not found and the line that shows it, and the working parts that answered. A coin nobody asked about yet is queued and read within minutes: the answer says how many seconds to wait before calling again. Free: 10 new coins a day per caller, coins already read are always free.

Every coin one wallet launched on Robinhood Chain. On Robinhood Chain (Pons and Long launchpads): how many, how many graduated from the bonding curve, whether the dev sold, and the latest launches with how each ended. Reads Robinhood Chain.

What anyone can learn about a wallet from Robinhood Chain alone: a privacy grade (A to F), a score out of 100, and each leak found (who funded it, linked wallets, holdings, active hours, launches, trading record, linked accounts) with tips. The grade measures what anyone can see, not whether the wallet is good or bad. Robinhood Chain only.

The newest coins launched on Robinhood Chain, newest first, from Toll's live engine: launchpad, age, pair, and the engine's short notes on each (dev record, first buyers, buyers, curve), with a link to the full check. At most 20. Robinhood Chain only.

How busy Robinhood Chain is right now, as Toll's live engine counts it: launches in the last 5 minutes and hour, graduations, launches by launchpad, new pools, trades a minute and volume. Robinhood Chain only.

Takes no parameters.

The call Toll made a few minutes after a Robinhood Chain coin launched, frozen and never edited: against / careful / clear (or launch facts only), the findings tallied, why, the dev's and funder's other coins of the week, and how it ended 24 hours later. Not the coin now: use check_coin for that. Robinhood Chain only.

One ERC-8004 agent registered on Robinhood Chain (identity registry 0x8004A169FB4a3325136EB29fA0ceB6D2e539a432), by its agent id: whether its registration card loads and from which host, its class (real service / site only / card only / broken card), whether its MCP server answered an initialize call, whether its x402 endpoint answered 402 with payment terms and who it pays, whether that payTo is the registered agentWallet, whether the agent's wallet has sent a transaction, when it was last checked and what changed. Plain facts from Toll's agent census, with the date and the source they were read from (the live census, or the 2026-10-28 snapshot), never a verdict. Robinhood Chain only.

One Uniswap v4 hook on Robinhood Chain, by its contract address: its name and where the name was read (the contract's own getter, Blockscout or Sourcify), whether it is a launchpad's shared hook, its 14 permission bits in plain words (runs on every trade, can take a fee or tax, can act when liquidity is removed...), whether its code can be changed by its owner (EIP-1967 proxy) or is a fixed clone, how many pools use it in Toll's chain data, and whether a test sell through its newest pool reverted (sells fail). With a $TOLL holder's Toll key: also the measured buy and sell cut in % and its latest coins with how each ended (the launch record, scored 24 h after launch). Facts, never a verdict. Robinhood Chain only.

Pre-sign check, before an agent signs anything on Robinhood Chain (chain id 4663): send the transaction (to, data, value, and from), an EIP-712 signature request (typedData: Permit, Permit2, TransferWithAuthorization) or an x402 payment (x402: the PaymentRequired from the 402, or one accepts entry; agentId optional), and Toll answers ALLOW / WARN / BLOCK with the reasons, as an ERC-8265 RiskAssessment. It reads approvals (unlimited, to a plain wallet, to a contract we do not know, to a wallet the coin's own check names), transfers (to a burn address, the token itself, a router, a flagged wallet, an unknown contract), swaps (the router, who it pays out to, and the coin bought, through Toll's coin check: BLOCK only for findings whose coins rugged at 40% or more in our calibration), and x402 payments (ERC-8478 payee verification: payTo against the seller's ERC-8004 agent wallet or a payee delegation it signed, read live from the Robinhood Chain or Base identity registry, with the outcome in x-toll; the seller's last delivery spot-check, the asset and amount). Calldata it cannot read is WARN, never ALLOW; a coin still being read is WARN with the seconds to wait. Robinhood Chain only. Facts, not advice.

Agent Pre-Sign Risk Report (ERC draft, ethereum/ERCs PR #2134): send a PresignRequest {version: "erc-presign/1", subject: {type: "calls", chainId: "eip155:4663", from: "eip155:4663:0x...", calls: [{to, value, data}], typedData?}, context?: {payment?, texts?, tokens?}} and get a PresignReport: typed facts about the unsigned request on Robinhood Chain, each read or not read at one pinned block (approval amount, unlimited, share of supply, expiry, current allowance; address code; issuer listing of stock tokens; ERC-8470 launch observations; ERC-8478 payee binding; control characters, mixed scripts and addresses in text), bound to the request by digest and EIP-712 signed by Toll (ERC-8004 agent #20030). No verdict: apply your own policy, and treat not read as unknown, never as clean. For an ALLOW / WARN / BLOCK answer use check_tx (which carries this report too).

A model picked each value's sentence or table cell; the number was read from that quote by code, never written by the model; figures the code could not read, and GAAP lines that disagree with the company's XBRL facts, were dropped. Read once per release (never per question). limit: values per release (1 to 60, default 25). Funds and foreign issuers (6-K) are not covered. Quotes are the company's words. Facts, not advice.
