Cumple&Cobra

Cumple&Cobra ("deliver and get paid") is AI-verified escrow for freelance software work. The client describes what they need; Muse Spark turns it into a frozen, hashed contract of verifiable criteria and generates a hidden test suite the freelancer never sees. The client deposits USDC into a Soroban escrow on Stellar testnet. When the freelancer submits, the code runs in an isolated black-box sandbox: hidden tests, deterministic browser checks with Playwright, and a visual judge comparing screenshots against the client's mockups. Muse Spark judges each criterion with evidence that is verified against the real material, and a deterministic rule has the final word, so the AI can never approve over a real failure. If everything passes, payment is released automatically, with the rules, workspace and verdict hashes recorded on-chain. The client never sees the code until the freelancer is paid. Prompt-injection and test-tampering attempts are detected and routed to manual review.
