BlockBeats report, on April 21, at the event "Decoding Web 4.0: When AI Agents Take Over On-Chain Permissions," Cobo demonstrated through a Skills Demo the practical application pathway of its agent-oriented "contractual execution" mechanism in real transaction scenarios. This mechanism structurally defines each transaction around four key elements—intent, execution path, constraint rules, and completion conditions—enabling agents to autonomously carry out operations within predefined boundaries.
In the demonstration, for basic scenarios such as Swap, users need to approve the contract only once; the Agent can then automatically execute trades within the defined constraints. Once the transaction is completed, the contract terminates and enters a pending-trigger state, minimizing long-term exposure to permission risks.
For complex scenarios such as cross-chain bridges, the Agent can autonomously plan a path (e.g., selecting a cross-chain bridge and executing the link) and package the complete execution plan as a set of contracts for user approval. Once approved, subsequent multi-step operations do not require individual signatures, significantly improving execution efficiency.
