Coinbase has introduced a new set of security features for users who link AI software with their trading accounts through the company's Agents feature. The update, known as Coinbase Agent Controls, gives users the option to define transaction limits and loss protection mechanisms before an AI agent is allowed to execute trades on their behalf. Users can configure how much an automated agent is allowed to trade and how much loss the portfolio can absorb before trading halts.

Announced November 11, Highlighted by CEO Brian Armstrong

The new Coinbase Agent Controls were announced on November 11. The update is intended to restrict the behavior of AI agents so that they cannot exceed trading limits defined by users. Coinbase CEO Brian Armstrong also highlighted the feature in a post on November 13.

The development arrives as individuals become increasingly interested in using AI to conduct operations in financial accounts. Coinbase has nonetheless made clear that users remain fully accountable for the operations carried out by their AI agents.

How Coinbase Agent Controls Limit AI Trading

The new agent control policies on Coinbase impose several limitations on the user's side before AI agents are permitted to execute trades through their accounts.

One policy allows users to specify the maximum dollar amount of each trade. Another lets them set a maximum daily trading volume. If an AI agent attempts to place any trade that exceeds those limits, the system blocks the order from being executed, enforcing the cap automatically rather than relying on the AI agent to follow instructions.

In addition, the platform has introduced an auto-stop feature that monitors whether losses incurred by the portfolio have reached the percentage set by the user. Once portfolio losses reach that threshold, the AI agent stops placing further trades.

Trading will not resume unless the trader decides to turn it back on manually through the Coinbase application.

A major benefit of Coinbase Agent Controls is that the restrictions operate directly through the company's servers. As a result, an AI agent is unable to bypass the restrictions or change the settings. The technique creates a separation between the commands provided to an AI and the trading guidelines themselves.

Agent Controls Do Not Automatically Close Positions

Despite the added security, users need to understand what happens when an AI agent reaches the maximum possible loss.

The auto-stop function will prevent the AI agent from placing any more orders once the loss threshold is hit. However, the platform has not confirmed what this means for activity already underway: Coinbase has not said whether the agent will cancel all pending orders, close existing positions, or stop the portfolio from incurring further losses. The mechanism for calculating portfolio losses has also not been disclosed by the platform.

The distinction matters because halting further trades is quite different from removing current exposure in the market. Clarification from Coinbase on how auto-stop treats pending orders and open positions, and on how portfolio losses are calculated, would address that open question for anyone running an agent.

Coinbase Developer documents these operations separately. For instance, obtaining an order ID does not mean that the order has been executed, and users should check the order status themselves. Order cancellation and closing positions are listed as separate functions in Coinbase's developer documentation, and their availability depends on the financial product.

As a result, it would be incorrect to assume that Coinbase Agent Controls have halted further trading activity simply because an AI agent has stopped working.

More Permissions Planned for AI Agents

Coinbase has also revealed that additional permission settings will be introduced in the coming days. The company currently lists product-specific permissions as an upcoming feature.

These settings will give users more control over their AI agents' ability to access various financial products, including cryptocurrencies, stocks, and derivatives. This adds another level of security by letting the account holder choose which markets their AI agents can access. Coinbase has not, however, revealed any definite date for the introduction of these permissions. The rollout of these product-specific permissions is the next development to follow for users assessing how much of an account an AI agent can reach.

US Banks Also Restrict Third-Party AI Access

The launch of Coinbase Agent Controls comes at a time when large financial institutions have grown more wary of AI agents gaining access to customer accounts.

According to Reuters' reporting, large US banks such as JPMorgan Chase, Morgan Stanley, and Charles Schwab are not allowing AI agents to access customer accounts. The stance reflects the difficulties financial institutions face as artificial intelligence becomes increasingly involved in financial transactions. While automated agents may make managing accounts simpler, there is concern over account security and responsibility. That split — institutions blocking agent access outright versus Coinbase permitting it under platform-enforced limits — frames how differently financial firms are currently approaching AI agents.

Coinbase Agent Controls offers one possible solution, as it enables trading restrictions to be managed from within the platform rather than through instructions to the AI system alone.

While the update brings additional safety measures for users, it does not remove the need for account monitoring. Users will still need to know how to pause an AI agent, cancel an open order, and close a position.
