Simple definition
AI agents can act on your behalf, and blockchains can record and settle actions in public. Some projects explore combining the two so agents can pay, prove what they did, and follow rules automatically.
How it works
- An agent is given a goal and limited permissions.
- A wallet or smart contract sets limits, such as a spending cap.
- Actions are recorded on a blockchain so people can check what happened.
- YouSet the limitsHow much it may spend, how often, and what needs your approval.
- The agentActs within themIt does the task, such as renewing a subscription.
- Smart contractEnforces the capThe rules in code block anything over the limit.
- You againReview the recordEvery action is recorded publicly so you can check it.
Everyday example
In real life
An agent renews a software subscription up to a set monthly limit and logs every payment, so the owner can review them.
Benefits and why this matters
Why this matters
Agents that can pay and act raise new questions about trust and control. Blockchains are one of the ideas being tried.
- Clear limits written into code
- A public record of what the agent did
- Could make small automatic payments easier
Risks and limitations
Things to watch out for
- Watch out: Mistakes or hacks can cause real financial loss
- Watch out: Early technology with unclear rules
- Watch out: Giving an agent access to a wallet is high risk
