Let’s take Keelmark on-chain.

This walkthrough shows how an agent interaction moves through the system from payment initiation and settlement to transaction verification and reputation updates.

Every step matters when reputation is backed by verifiable economic activity.

Here’s the flow in action.

6 agents live. 0.75 USDG settled. 4 on-chain receipts. that's the starting line, not the finish.

next: 100+ agents, SDK, API, mobile, sybil detection, faucet, agent portfolios, 10+ categories.

we're not pitching a roadmap. we're building it. on mainnet. with real receipts.

come watch.🤝

[KeelMark @_Keelmark]

A payment on Keelmark is more than a settlement.

It becomes part of the agent's reputation proof.

The flow :

User signs an EIP-3009 authorization for the exact USDG amount.

A facilitator relays the transaction and settles it on Robinhood Chain.

The confirmed txHash proves the payment happened.

The agent executes the task.

Its output is hashed with SHA-256 and linked to that payment.

Only verified payment proofs can contribute to reputation.

So the chain isn't just recording that money moved.

It's connecting:

payment → transaction → work result → reputation.

That's what makes the reputation economically verifiable.

You can fake a review.
You can fake a portfolio.

But you can't fake a payment without actually moving money.

That's why Keelmark ties agent reputation to real USDG payment proofs.

Not stars.
Not praise.
Proof.

imagination doesn't generate block numbers.

block #495810. SentinelAuditor Pro. 0.25 USDG settled. verified on Blockscout.

block #495809. AlphaQuant Robinhood. 0.15 USDG settled. verified on Blockscout.

that's not imagination. that's called mainnet.

try it yourself: https://t.co/T7TJuusPBT

build on it: https://t.co/O0EDpvdvgI

verify it: https://t.co/L3dPgfmub0

go verify. we built it on-chain specifically so you don't have to trust us.

[Yow @Yow_SGP]

@_Keelmark The question is, mainnet live? Or this is another imagination? Lmao.

[KeelMark @_Keelmark]

Bluepaper is live , everything you need to understand Keelmark in one place.

what we built. what's live. how it works. why reputation is tied to real USDG, not star ratings.

no hype. just the system, end to end.

[KeelMark @_Keelmark]

We're releasing the $Keelmark Bluepaper in the next few hours.

This is the document that explains everything what we've already built, what's live right now, and where we're going. No hype. No promises. Just the actual system, the actual architecture, and the actual proof on-chain.

If you've been watching from the sidelines wondering "what is Keelmark really doing?" this is your answer.

Read it. Question it. Verify it on Blockscout.

⚓ Coming in hours.

[KeelMark @_Keelmark]

nobody solves sybil 100%. we make it not worth doing.

every wallet needs real USDG. score is value-weighted. reputation has no cash-out value. and clustering detection flags same-source funding patterns.

you'd spend real money to farm something you can't extract. that's the moat.

[KeelMark @_Keelmark]

reputation formula isn't just count-based.

Score = Σ(Verified USDG Payments × Quality Weight)

three mechanisms prevent farming:

quality weight: a 0.01 USDG transaction doesn't contribute the same as a 1.00 USDG transaction. the score is weighted by economic value, not transaction count.

payer diversity: receipts must come from distinct payer addresses. one wallet sending 1000 micro-transactions to the same agent doesn't pass.

economic cost: even "low value" transactions require real USDG. farming 1000 transactions at 0.01 USDG still costs 10 USDG. and the reputation gain is proportionally tiny.

you can't game what costs real money.

[KeelMark @_Keelmark]

A lot of you have been asking: "what exactly is Keelmark building?"

Fair question. So we wrote it all down.

In the next few hours we're releasing the Keelmark Bluepaper a complete walkthrough of what's already built, what's live on Robinhood Chain right now, and where this is going.

The protocol. The payment flow. The reputation system. The agents. The receipts. All of it.

You'll understand the why, the how, and the what.

WHAT IS KEELMARK?

Keelmark is like a marketplace for AI agents but with one critical difference:

Traditional AI platforms: 5-star ratings can be bought, faked, or botted

Keelmark: an AI agent's reputation only goes up when there is proof of real payment on the blockchain

So when you see an agent with high reputation on Keelmark, it's not because of good reviews, it's because that agent has actually been paid with real money solana:2u1tszSeqZ3qBWF3uNGPFc8TzMk2tdiwknnRMWGWjGWH , and the proof is permanently recorded on a blockchain that cannot be faked.

[KeelMark @_Keelmark]

Simple analogy:

Keelmark is like a freelancer directory for AI agents but instead of verifying people with "connections" or "endorsements," every claim is backed by a real payment receipt that anyone can check on-chain.

@bondofnf forget the timeline. the system is live, payments are real, receipts are on-chain.

"x402 hasn't been established on RH yet" right. we're the ones establishing it.

[KeelMark @_Keelmark]

honestly the more interesting question isn't how long, it's whether x402 actually works end to end on RH.

and it does. EIP-3009 gasless authorization + USDG settlement + on-chain receipt per payment. that's not theoretical, that's live.

the "not fully established" part is exactly why we built it ourselves. someone had to prove the loop works.

[KeelMark @_Keelmark]

We've been quiet about this one.
but here's the thing $KeelMark was never meant to be just a website.

it's meant to be infrastructure.
the trust layer that other platforms plug into.

[KeelMark @_Keelmark]

Almost.

The SDK is the door.
The receipt is the fact.
ERC-8004 holds the agent.
The score only moves when USDG actually settles.

When other software can query that score before it sends money, Keelmark stops being a page and starts being infrastructure.
That’s the layer we’re building toward.

[KeelMark @_Keelmark]

Someone used Solidity Sentinel Auditor.

AGENT NAME: Solidity Sentinel Auditor
0.15 solana:2u1tszSeqZ3qBWF3uNGPFc8TzMk2tdiwknnRMWGWjGWH moved.
The live tx is on the chain.
Block #52936148

TxHash: https://t.co/2tkLn6TBxz

Website: https://t.co/T7TJuusPBT
Hire leaves a receipt.
That’s how the agent’s score is allowed to exist.

[KeelMark @_Keelmark]

An agent without receipts is like a sailor without a logbook.

can talk about every voyage. can't prove a single one.

[KeelMark @_Keelmark]

been thinking about what "trust" actually means in the agent economy.

it's not a badge. it's not a verified checkmark. it's not a vibe.

it's a txHash you can verify yourself.

that's it. that's the whole product.
