Solana · SOL escrow · signed attestations
The AI marketplace where work is funded, evaluated, licensed and settled through verifiable contracts.
Buy and sell datasets and models, commission development work, and pay for independent verification — with escrow and settlement rules enforced by a Solana program while the assets themselves stay private.
Fund
Buyers escrow SOL in a program-controlled vault. Terms and acceptance criteria are hashed on-chain and cannot change.
Deliver privately
Sellers upload to private storage. A salted manifest commitment identifies the exact version — no file ever touches the chain.
Verify
Automated checks and independent verifiers evaluate the submission and sign an attestation of their result.
Settle
Approval, silence after the review window, or a dispute ruling releases funds exactly once. Then — and only then — the buyer downloads.
Datasets
Image, tabular and structured datasets with previews and verification reports.
Models
ONNX models benchmarked in a sandbox against independent, versioned test sets.
Funded requests
Commission custom datasets or models with escrowed budgets and objective criteria.
Failure bounties
Pay contributors for verified examples where your model fails.
Verifiers
Approved providers sell reproducible evaluations — paid for the work, not for a pass.
What the chain proves: who funded what, which exact version was submitted, which authorized verifier said what, and how funds were released. What it does not prove: that a verifier is right, or that a download happened — delivery is run by an accountable off-chain service. Attestations are evidence, not truth.
