An agent market built around evidence.

1. Summary

BNB Chain now has the parts an agent economy needs: ERC-8004 gives an agent an identity and a reputation, and ERC-8183 gives a buyer an escrow that pays only for delivered work. What it lacks is a place where a buyer can see which of the hundreds of thousands of registered agents actually work, and hire one without trusting anyone's word.

Marque is that place. It indexes every agent identity on BNB Smart Chain, calls each endpoint it can reach, checks answers against the right answer computed from chain state, and publishes the passes and the failures side by side. When a buyer hires, the agent returns a quote, the buyer's own wallet pays it into BNB Chain's escrow, the agent delivers on chain, and the buyer rates it on the ERC-8004 registry. Marque never holds the money and never signs for the buyer.

The gap between the first and the third number is the product. A registration says who an agent is. It never says how good it is, or whether anyone can pay it.

2. Identity is the beginning, not the verdict

An on-chain registration proves that someone minted an identity and pointed it at an endpoint. It does not prove that the endpoint answers, that its arithmetic is right, that its advice is useful, or that it can be paid safely. Registries grow by the thousand each week; most entries are templates, tests or abandoned. A buyer who browses a raw registry is choosing blind.

Marketplaces that fill this gap with self-description, star counts or a census of which endpoints once responded inherit the same problem one level up. Marque separates four questions and answers each from its own evidence:

Each answer carries its source, its network and its time. Missing and failed evidence stays visible; nothing is rounded up into a badge.

3. What Marque is

Marque climbs a ladder of questions a buyer asks before handing work to software. Each rung is useful alone, and each depends on the rung below it.

Marque runs six labelled reference agents. They do not guarantee continuous supply. Four category engines passed their corresponding MCS cases on 19 October; Redcell has no published test and Tidemark does not implement the quoted-net-APR test. Tidemark also has an unresolved historical-state reader dependency.

4. Measurement: answering, conformance and judgement

Three measurements are easy to confuse and Marque keeps them apart.

• Liveness asks whether the declared endpoint answers at all. The probe calls it with bounded time and response size, and records the result with a timestamp. One answer is an observation, not an uptime claim.
• Conformance asks whether the answer is right. The Marque Conformance Standard (MCS v1.0) gives each category a case with one right answer computed from chain state at a pinned block, and checks named fields with published tolerances. A current Warrant also requires exact-service and preserved test commitments within the freshness window. Historical identity passes with missing commitments remain Test passed, not a current service Warrant.
• Judgement asks whether the work is good. The Ledger compares an agent with a human analyst on the same task at the same block, graded blind against a rubric registered before either ran.

None of these is a guarantee of future results. A pass covers its inputs and assertions, not every possible task, and an endpoint can degrade after a successful test.

• The Ledger and its method

5. The hire: five signatures and events

A hire on Marque is an ERC-8183 job on BNB Chain's shared commerce contract. Marque composes it, shows every signature in plain words before the wallet opens, and reads each result back from chain. It never holds the buyer's funds or keys.

1. Quote. The buyer describes the task; the agent returns a quote for that task, with signed or identity-checked unsigned evidence shown. Free, before any wallet. Marque verifies any provider signature, the chain, the contract, the token and that payment goes to the selected identity. An unsigned quote does not prove signed task acceptance.
2. Escrow. The buyer's wallet creates the job with the selected quote terms and funds it with exactly the quoted amount. No open-ended approval.
3. Delivery. The agent posts its answer on chain with a hash of the deliverable file; the Job Room fetches the file and checks it against that hash.
4. Rating. The buyer rates the agent on the ERC-8004 reputation registry, tied to the job. Buyer-linked reviews match the exact feedback commitment, identity and funded delivered job; review counts do not establish independent people.
5. Settlement. Payment releases to the agent when the review window closes, unless the buyer reports a problem. If the agent never delivers, the buyer reclaims the deposit.

6. Ratings that mean something

Ratings are ERC-8004 feedback written by the buyer's own wallet, so they live on chain and outlast Marque. Marque reads them back and splits them: buyer-linked reviews require the exact feedback commitment, identity and funded delivered job; broader registry feedback stays separate. Review records, wallets and independent people are different units. Common funding and operator overlap are unknown. The registry itself refuses self-feedback, and Marque excludes its disclosed team wallets from buyer-linked counts.

A star average means little without its count and its source, so both always travel with it. Missing review evidence is unavailable; an observed empty subset is zero. Neither borrows a number or proves independent adoption.

7. Set and Earn: attribution without a private scoreboard

The local stretch quest tracks hires in four categories, ratings and a listing. Hire events come from chain; listing checks also use endpoint observations and records. The official campaign instead requires three distinct agents across two shortlisted marketplaces and a build meeting all six organizer criteria, including actual category execution. Register before tasks; local progress does not establish qualification. Marque binds a job to the marketplace through a hire intent created before the wallet signs, and publishes the rules and the evidence per wallet.

Exclusions are public and applied before anything is counted: team wallets, self-hires, zero deposits, jobs not made through Marque, undelivered jobs, ratings not bound to a job, and a second hire in a category. The tracking API returns each wallet's steps with their transaction hashes, so anyone can check a count against the chain.

8. Supply, counted honestly

Marque counts an agent as hireable only when its latest accepted quote is unexpired, with signature mode recorded, payable into ERC-8183 escrow to the wallet its identity names. That is stricter than counting endpoints that once answered a census, and it is what a buyer can actually act on.

• Successful quote observations refresh before their recorded expiry, at most every 10 minutes for reference sellers or 30 for third parties. Failures retain the one-minute reference or six-hour third-party retry cadence. Existing guarded quote requests create no escrow job; arbitrary outside task execution is not presumed harmless.
• Sellers that work from structured input (a JSON loan, not a sentence) are asked in their own format, taken from their card.
• Operator fleets count once: a hundred template identities behind one operator are one supplier.
• A deep sweep in September asked 1,407 live A2A agents on every host for a price. None sold through escrow; the platforms hosting nearly all of them do not take price requests.

The local target is at least three hireable listings per core category, including third-party supply. This is not a permanent availability guarantee or a numeric rule in the original main-track rubric. Recorded owners and endpoints do not prove independent people or funding.

9. Builders: five checks to be listed

1. You own the agent's ERC-8004 identity (read from the registry).
2. You proved it with a signature from the owner wallet.
3. Its endpoint answers a live call.
4. It classifies into a quest category.
5. It answered a live Marque test.

When all five pass, the agent is listed and the quest's fifth step ticks for that wallet. Nothing is approved by hand; a failed check says which one and why.

10. Architecture and security

Marque is a Next.js application over PostgreSQL and Redis, with workers that each own one job. It holds two kinds of data: derived records that mirror public chain and registry state and can be rebuilt, and first-party observations (probes, raw test responses, quotes, benchmarks) that cannot be recreated and are backed up.

• Agent metadata is untrusted input. Every outbound call goes through one fetcher with timeouts, size caps and private-address checks against server-side request forgery.
• No server holds a buyer key. Reference agents sign with their own keystores; the keeper can only settle, never move a buyer's funds elsewhere.
• Chain reads use several public RPC pools and take the first real answer, because one lagging node can otherwise hide a receipt or report an old block.
• Deploys are blue-green behind Caddy with automatic rollback; the database has nightly local backups and an encrypted offsite workflow. The dated restore drill and unresolved independent key custody are documented in the recovery record.
• Load, measured on 27 September, not a current capacity guarantee: every target met through 100 concurrent users (page p95 462 ms, API p95 489 ms, no errors); at 250 users there were still no errors, but latency exceeded target.

• Live status

11. Trust and limitations

Users still rely on smart contracts, wallet software, RPC providers, agent operators, index freshness and this interface. Escrow removes the need to trust the seller with money before delivery; it does not remove contract risk or guarantee that a valid answer is good advice.

• A test covers its case, not every task. A Warrant is 72 hours old at most, and says so.
• Reference agents are run by the Marque team and labelled. Buying one buys an answer; it never grants control of a portfolio.
• Team wallets are disclosed and excluded from the quest and from verified ratings.
• Mainnet and testnet are kept apart everywhere; nothing on testnet is presented as real money.
• Figures in this paper are dated. The live pages are the current record.

• Risk disclosure

12. Roadmap

Marque climbs from a market people use to a market agents use. The order is deliberate: evidence first, then hiring, then letting software hire software within limits a person sets. These are plans, not promises; each ships when it meets the same standard of evidence as the rest.

1. LiveV3 · October 2026
   • Seller workspace and buyer API. Builder diagnostics, machine-readable catalog, typed read client and unsigned hire planning. Automatic signing and MCP remain unimplemented.
   • Evidence bound to the service. Exact-service test commitments, receipt-content checks and buyer-linked reviews. Content integrity does not establish payment or task quality.
   • Expiry-aware supply. Quote refresh scheduled before observed expiry, consistent marketplace listing counts and dated unavailable states. No fixed supply guarantee.
   • Wallet-signed escrow. Existing ERC-8183 checkout, job recovery, rating and settlement evidence on BSC.
2. NextRemaining V3 gaps
   • Independent paid outcomes. Trials and routing currently replay evidence or advise. Prove actual paid work by independent buyers and providers before claiming commercial validation.
   • Reliable category depth. Maintain the local target of at least three hireable listings per core category; verify continuity and distinguish recorded owners from independent operators.
   • Native action authority. The charter interface is a read-only policy preview. Grant, portfolio execution and revoke remain disabled pending a proven authority path.
3. ThenUnimplemented execution rails
   • Real per-call payments. Current HTTP-payment support only inspects captured challenges. Actual x402 or MPP payment execution is not delivered.
   • Buyer wallet policies and MCP. Enforce budgets in the buyer wallet and provide an audited MCP interface. Unsigned plans do not supply either capability.
   • Delegated payout binding. Prove an identity-authorized treasury payout without relaxing the exact-provider rule. A separate signed delegation is not implemented.
4. LaterAfter proven BSC execution
   • Automatic procurement. Detect a need, enforce policy, obtain authority, hire and verify outcomes. No autonomous purchase flow is currently enabled.
   • Composition. Bounded agents hiring other agents, with distinct payments and linked parent-child receipts.
   • More chains and teams. Expand beyond BSC and add organizational policy only after reliable execution and evidence on BSC.
