CoinGraph, one project wey come from the Cardano track, don win the overall Origins hackathon wey dem hold side by side with TOKEN2049 for Singapore. The Cardano Foundation announce the results on October 8 after 36 hours of development. Cardano Card take first place for the separate Cardano track competition, followed by zx402 and Nitrane Systems / Uplift.
CoinGraph Dey Check Data Before Agents Act
CoinGraph dey provide structured assessments wey applications and AI agents fit request before dem start any financial action. E bring market data, liquidity, on-chain flows, and token information together, and e dey attach sources and timestamps to the findings.
Each assessment get digital fingerprint wey allow people to check whether anything change later. The application wey request the assessment still get responsibility to decide whether to proceed.
The project don provide public demo and source code for the build wey dem do for TOKEN2049. E Chainlink CRE verification workflow dey run inside simulator for now.
Cardano Track Winners Build Agent Commerce
Cardano Card show purchasing service wey fit accept Amazon product request, budget, and delivery address from another agent. According to the team documentation, funds go lock inside Masumi escrow while Agentcard dey process the purchase.
Once order placement succeed, payment go trigger to the service, but if purchase fail e go follow refund path. The team report say real Amazon orders happen alongside escrow transactions for Cardano Preprod. Payment depend on placing the order, no be on top confirm physical delivery.
Second-place zx402 dem present am as private funding system wey use shared stablecoin pool and zero-knowledge proofs to hide where the agent funding dey come from.
Third-place Nitrane Systems / Uplift present 13-agent team for e-commerce growth tasks. The Foundation description identify Masumi escrow for engagements and Chainlink verification of deliverables before payment.
Cardano Payments Connect Agents With Services
The prototypes dey use two payment approaches. x402 dey support payment for individual API requests, while Masumi escrow go hold funds until agent task conditions don meet.
Hirakumi, wey the Foundation still highlight, dey apply response checks to paid API access. The prototype go use usage credit only when the answer meet the service defined requirements.
CoinGraph public build dey demonstrate the x402 flow for Cardano Preprod using test ADA: the API go return payment request, the agent go pay and retry, and the service go release the requested assessment. E still offer Masumi payment route for tasks, with the result hash recorded on-chain.
