Escrow for sponsored posts on X

Sponsored
posts, paid
on proof.

The brand locks the KOL's fee in USDG on Robinhood Chain. The KOL posts. Stamped watches the post and releases the money once it has stayed up. No post, no pay.

How it works

Lock. Post. Paid.

Every deal runs through Stamped's escrow contract on Robinhood Chain. The brand never pays first on trust, and neither does the KOL post first on trust.

    USDG in escrow

    The brand sends an offer to any X handle and funds it in one transaction: the price plus a 1% fee, in USDG. The KOL sees money that's already there.

    The KOL accepts with their X account, posts, and pastes the link. We check it's theirs and matches the brief, then keep looking until the hold ends.

    The post stayed up: the escrow pays the KOL their full price, automatically. It came down or never went up: the brand gets everything back, fee included.

Proof, not promises

Every deal ends with a postmark.

The brief becomes a checklist the post has to pass: the ticker, the link, the tag, the disclosure. Each deal gets a public receipt with the post, the checks and the transactions.

For brands

Pay for posts that actually went up and stayed up. Refunded automatically, fee included, if they didn't.

For KOLs

The money is locked before you post. Paid in full the moment the hold ends. No invoices, no chasing, no gas.

Watched for you

Checked against the brief at submission, then every 10 minutes. Three misses in a row and it counts as down.

One middleman, on-chain

The escrow can only pay the KOL or refund the brand. Disputes go to Stamped, with the post and the chat.

Pricing

The KOL gets their price. To the cent.

The brand pays the price plus 1%. The KOL pays nothing: no fee, no gas, not even a wallet to set up, since signing in with X makes one.

USDG on Robinhood Chain. The KOL pays no fee and no gas. Whoever invited either side gets 20% of the fee.

FAQ

Questions, answered.

Who holds the money?

A smart contract on Robinhood Chain, not Stamped's wallet. It can only do two things with a deal: pay the KOL bound to it, or refund the brand that funded it.

What if the KOL never posts?

The offer has a posting window. If no post passes the checks by then, the brand is refunded, fee included. Same if the KOL declines or never accepts.

What if they delete the post early?

We look at it every 10 minutes. Three misses in a row, spread over at least 20 minutes, and the deal is refunded to the brand.

Does the KOL need crypto?

No. Signing in with X creates a wallet on Robinhood Chain, and the KOL never pays gas: Stamped's keeper sends every transaction for them.

What does it cost?

1% of the price, paid by the brand on top. Refunds give the fee back. A share of the fee goes to whoever invited either side.

What if we disagree?

Either side can open a dispute while the post is live. Auto-release stops and Stamped decides, with the post, the brief and the chat in front of it.

Is this allowed on X?

Paid partnerships are fine on X when they're disclosed. That's why every brief asks for #ad (or #sponsored, #paid) by default.

No post,
no pay.

Sign in with X, send an offer to any handle, or put your rates on your Stamped page. Your handle and your track record are your reputation.
