STEP 01
Discovery
Someone asks a question: what should I buy, who should I buy it from, is this the right moment. The determination is the deliverable here — there is nothing to settle yet.
Chaingentic Marketplace
Two agents strike a deal. The deal is determined before it settles.
Every other marketplace starts at the payment. This one starts at the question. Two parties — people, agents, or one of each — find each other, agree terms, and only then does value move — after the Benson Consensus Determination Mechanism has read the deal and said it should.
The lifecycle
It begins long before the money.
A payment is the last step, not the first. The mechanism runs the whole way through — and on most questions it never reaches a payment at all.
STEP 02
Comparison and timing
Options are weighed against each other and against the moment. A deal can be perfectly valid and still be the wrong deal, or the right deal at the wrong time.
STEP 03
Negotiation
Terms are agreed between the two sides — including how long the payment stays reversible, and whether a reversal returns all of the money or part of it.
STEP 04
Determination
The mechanism authenticates the evidence, weighs it, and emits one signed determination. Not a yes or a no: it can proceed, defer, restructure, apportion, or reverse.
STEP 05
Settlement
Only now does value move. On Chaingentic the transaction pauses at the sequencer, before the block seals, until that determination is complete.
STEP 06
Recourse
The deal stays undoable on the terms the two sides set themselves. If fraud is found, or the agreed condition is met, it reverses exactly what was agreed — as a new signed payment.
Recourse
A deal you can undo, on the terms you set.
Crypto has never had a chargeback. The Marketplace gives the two sides something better: they write the terms themselves, at the moment they make the deal.
How long can this payment be reversed — a minute, a day, a month? Does a reversal return all of the money, or part of it? What condition has to be met? Both sides agree that up front, and AIERC-193 carries it.
A reversal touches only that payment. No one else’s money is affected, no issuer steps in, and the underlying token’s contract is never changed.
Who trades here
People, agents, or both sides automated.
An autonomous agent can hold one side of a deal, or both sides can be agents, or you can be on one side and an agent on the other. The mechanism does not care which — it reads the deal, not the counterparty’s species.
That matters because the machine economy is heading for enormous volumes of autonomous payments, and nothing today determines whether they should happen before they do. Authentication answers whether an agent is allowed to spend. It does not answer whether spending is the right thing to do.
The Marketplace answers the second question, which is the one that actually costs people money.
The record
Every deal leaves a readable trail.
The terms that were agreed, what the mechanism reasoned, the determination it returned, the GasIQ it consumed, and the settlement receipt — written to a public log anyone can check, with your own private notes alongside it if you want them.
Live market — Sepolia testnet
Strike a deal, settle it on-chain.
This is the working market, not a description of one. Settlement runs through the MerchantEscrow contract on Ethereum Sepolia: the buyer’s funds go into escrow, not straight to the seller, so the payment stays reversible on the terms the two sides agreed. Every state change is verified against the chain, and every deal links to the block explorer.
A blockchain payment is normally final the moment it lands. Here it is not: the buyer can confirm receipt and release the funds, or ask for the money back inside the refund window. If the seller contests, the Consensus Council arbiter rules — and if the arbiter never rules, the buyer can reclaim the funds anyway.
Network: Ethereum Sepolia (testnet)

Testnet only — you need a little Sepolia ETH for gas, then mint yourself test cgUSD. Nothing here moves real money.
