Trezor's software product lead, Denis Rojčyk, has argued that AI agents should not be given autonomous control over cryptocurrency wallet transactions. Speaking on a TOKEN2049 panel, Rojčyk said a human must provide the final signature through a hardware wallet before any transaction is completed.
The panel took place at TOKEN2049 on October 7-8, 2026, and a recording of the session was released on October 26, 2026.
Assistance, not autonomy
Rojčyk's position distinguishes between an AI agent helping to prepare a transaction and an AI agent completing one independently. In his framing, an AI agent can assist with preparing a transaction but cannot finalize it on its own.
The mechanism for this is the hardware wallet itself. A physical device, held by the user, provides the human-authored signature that makes the transaction valid. Without that step, no funds move.
Trezor's current products align with this philosophy. Its devices do not support any autonomous signing capabilities for AI agents, and every signature still requires manual approval.
Contrast with MetaMask
Rojčyk's stance stands in contrast to MetaMask's approach. MetaMask's Agent Wallet allows AI agents to operate within parameters defined by the user, without requiring hardware confirmation for each transaction.
Under MetaMask's model, the user sets the rules in advance and the agent acts within those guardrails. Under Trezor's model, the human signs off at the moment of execution, every single time.
Why the human signature matters
The core argument for a hardware signature concerns where trust is placed. If an AI agent can sign on its own, the security of funds depends heavily on the agent behaving correctly. That includes the model, the software around it, and the data it is fed. Any weak link becomes a potential path to the assets.
Requiring a physical signature narrows that attack surface. An agent could be tricked, misconfigured, or simply wrong, and the transaction would still stall until a person reviews it and confirms on a separate device.
Implications for wallets and users
For users, the practical question is what kind of risk they are comfortable carrying. Rule-based agent wallets ask users to think carefully about the limits they set ahead of time. Hardware-gated models ask users to stay involved at the point of every transaction.
Trezor's position also sets expectations for its own roadmap. With its devices offering no autonomous signing for AI agents, any future move toward agent-friendly features would be measured against the stance Rojčyk laid out at TOKEN2049. The bar he described is a human-authored signature, not a policy setting.
