KOL-Escrow

What I built: KOL Escrow, an escrow for paid posts on X, running on NEAR. A project locks its campaign budget in a NEAR contract. KOLs apply with their X handle and price, and the project accepts or rejects. Accepting moves that KOL's fee into a deal. The KOL posts on X and submits the link. An agent confirms the post is theirs, contains the required text and went up in time, then watches it through a hold window. Kept up, the KOL is paid. Deleted or edited, the project is refunded. Every verdict and its reason is stored on-chain. Paid KOLs can cash out to USDC on other chains through NEAR Intents.

What it's for: KOL deals on Crypto Twitter run on trust. Projects pay KOLs who delete the post days later, and KOLs post for projects that never pay. KOL Escrow replaces that trust with locked money and a checked post. The agent signs with a NEAR function call key limited to record_post, release and refund, so it can only move money between the two sides of a deal. Timeouts work both ways: anyone can refund the project if no post is verified, or pay the KOL if the agent goes quiet. One post can only pay one deal.

Who it's for: Web3 projects that pay KOLs to promote launches and campaigns, and KOLs who want proof they'll be paid before they post. It's live on NEAR testnet with a built-in test wallet, so anyone can try the full flow in a minute.
