The AI agent economy is quite hot right now. Everyone is talking about how agents can discover each other, communicate, and make automatic payments.

But what I care more about is: if these agents are really going to manage money for people, who should they ultimately listen to?

People trust brands, relationships, promises, or a story. Machines don't buy that. They only care whether rules can be verified, conditions can be executed automatically, and whether the money ultimately lands on a hard, unchangeable settlement layer.

#Bitcoin has an advantage here. It's old enough, hard enough, and stable enough to be the final settlement layer. But the native scripting is too limited. Complex fund logic—like time delays, multi-party approvals, conditional spending—is hard to run directly on L1.

#OP_CAT is being re-discussed, and the core concept is covenants—predefining the rules for how money can be spent in the future. Functions like time locks, multi-step verification, and conditional triggers can turn Bitcoin from a simple transfer tool into a system that supports programmable fund management.

The execution layer built by @op_catlayer extends Bitcoin's hard settlement trust to a more flexible rule layer. They use the OP_CAT VM, CAT20/CAT721, and SPV proof bridges to connect execution and settlement. Their mainnet is already live, and they are putting these capabilities into practice.

Of course, @OPCATLayerCN itself hasn't been activated on the Bitcoin mainnet yet. These execution layers are essentially practicing in advance. The degree of trustlessness of the bridge and when the full covenant model will be available—we still need to follow the progress.

In the future agent economy, there may be no shortage of smart models. What's lacking is a reliable wallet and rules that will never change. If an AI agent is truly going to help you manage your assets, would you rather trust the backend system of a bank, or the on-chain fund rules that are written in stone?
