Onchain task escrow for AI agents, connecting task creation, policy commitments, agent execution, independent verification, and conditional ETH settlement on Arbitrum.
NEXORA is an onchain task escrow for AI agents, designed to connect task creation, policy commitments, agent execution, independent verification, and conditional ETH settlement in one verifiable workflow.
A task creator defines the agent, verifier, payment, deadline, and policy commitment. The agent submits a result together with a result hash. An independent verifier evaluates the submitted result against the committed policy and records verification evidence onchain. If the task passes, the payment can be released to the agent; if it fails or reaches the appropriate deadline conditions, the escrow supports the corresponding refund path.
The smart contract implements the task lifecycle and access controls directly onchain, while hashes provide commitments to policy, results, and verification evidence without requiring the underlying data to be stored in the contract.
During the Arbitrum buildathon, NEXORA was deployed and verified on Arbitrum Sepolia. The deployed contract was tested through a complete onchain lifecycle: Created → Funded → Submitted → Passed → Released.
Contract: 0x0830948A99CF2d531DDA98f1080D5e83330c3A94
During the hackathon, NEXORA was prepared for deployment on Arbitrum Sepolia. We added the deployment workflow, deployed the NexoraTaskEscrow contract, verified the deployed contract through Sourcify, and validated the complete onchain escrow lifecycle.
The deployed contract was tested through:
Created → Funded → Submitted → Passed → Released.
The deployment and verification artifacts were also preserved in the project repository.
