Cobo Showcases 'Contractual Execution' Solution for Agent Transactions: One Authorization for Multi-Step Operations Balancing Autonomy and Security

On April 21, at the event ‘Decoding Web 4.0: When AI Agents Take Over On-Chain Permissions’, Cobo demonstrated its ‘Contractual Execution’ mechanism for Agents through a Skills Demo, showcasing its application in real transaction scenarios. This mechanism structurally defines each transaction around four key elements: intent, execution path, constraint rules, and completion conditions, allowing Agents to autonomously complete operations within preset boundaries. In the demonstration, for basic scenarios like Swap, users only need to approve a contract once in advance, enabling the Agent to automatically execute transactions within the constraints; once the transaction is completed, the contract terminates and enters a pending state, thus avoiding long-term exposure to permission risks. For more complex scenarios like cross-chain Bridges, the Agent can autonomously plan the path (such as selecting cross-chain bridges, execution links, etc.) and package the complete execution plan into a set of contracts for user approval. Once approved, subsequent multi-step operations do not require individual signatures, significantly enhancing execution efficiency.
