CoinGraph wins TOKEN2049 Origins Hackathon for AI agent payments on Cardano

by@Cardano_CF

Summary

The overall winner of the @TOKEN2049 Origins Hackathon was CoinGraph, a project that developed a system on the Cardano blockchain which provides autonomous verification before AI agents perform transactions. CoinGraph enables agents to query whether they can execute a transaction, returning a detailed verdict based on a variety of factors. This hackathon, focused on creating a functional agent economy, showcased several innovative projects, such as zx402, which built a private funding rail for AI agents, and Cardano Card, enabling agents to make purchases on platforms like Amazon. The event highlighted the importance of verification and trust, as all projects integrated independent oracles to ensure that only verified outputs triggered payments, reinforcing the reliability of the systems built.

Analysis

x402: x402 provides a payment protocol enabling AI agents to make per-call or per-request payments over HTTP with 402 responses. It served as a core rail for on-chain settlements on Cardano in several TOKEN2049 Origins Hackathon entries. zx402: zx402 is developing a private funding rail for AI agents on Cardano that uses zero-knowledge proofs and shared stablecoin pools. It earned second place in the Cardano track of the TOKEN2049 Origins Hackathon. Masumi: Masumi serves as Cardano's marketplace for AI agents, handling registrations, escrows, and payouts for agent services. Hackathon teams including the overall winner and several track placers used Masumi to manage secure payments and workflows for AI-driven tasks. Cardano: Cardano is a proof-of-stake blockchain platform that supports smart contracts and decentralized applications. The Cardano track at the TOKEN2049 Origins Hackathon showcased multiple winning projects building payment rails, escrows, and AI agent tools directly on the network. Hirakumi: Hirakumi allows API owners to monetize their endpoints for AI agents by adding a verification layer that checks outputs against published promises before payment. It was highlighted as one of the event's best overall projects and runs on Cardano preprod with x402 integration. Chainlink: Chainlink operates a decentralized oracle network that supplies external data and performs independent verifications through its CRE workflows. Multiple hackathon projects, including CoinGraph and Uplift, incorporated Chainlink for attesting proofs and scoring deliverables before payments. CoinGraph: CoinGraph delivers crypto intelligence infrastructure designed for AI agents, stitching together market data, on-chain signals, and risk checks into verifiable verdicts with source proofs. It won the overall TOKEN2049 Origins Hackathon by enabling agents to confirm conditions before executing payments on Cardano via x402. AI Agent Payments: Hackathon participants built working systems where AI agents pay only for verified outputs using on-chain mechanisms on Cardano. Hackathon Outcomes: Teams shipped functional agent economy tools, including payment checks and private funding rails, in a short development window at the event. Verification and Trust: Projects integrated independent oracles to confirm AI work and API responses before releasing funds from escrow.
