Attestation (Agentic)
What Is Agentic Attestation?
In general cybersecurity, an attestation is a cryptographic statement used to verify a specific fact, such as the integrity of a software environment or the identity of a user. These receipts can be issued by various entities, including other agents, decentralized services, or DAOs. We use the term “agentic attestation” to refer specifically to these receipts when they are used to delegate authority from a human owner to an autonomous system.
In a decentralized ecosystem, trust must be established through evidence rather than reputation alone. An agentic attestation serves as the verifiable proof that a human owner actually authorized a specific intent. This mechanism ensures that every action taken by an AI agent can be traced back to a valid authorization, distinguishing a legitimate request from a tethered agent from a malicious action by a rogue system.
How Agentic Attestation Works
The process of generating an attestation begins with the human owner and their signer (hardware wallet). When you decide to delegate power to an agent, you define the parameters of that power, such as a spending limit or a specific timeframe.
The technical workflow typically follows these steps:
- Creation: The user reviews the delegation details on their Secure Screen. Once confirmed, the hardware device uses its private key to generate a digital signature.
- Issuance: This signature is packaged as an off‑chain Verifiable Credential or recorded as an onchain attestation. This receipt contains the metadata of the permission, such as the agent’s unique identity and the specific rules it must follow.
- Presentation: When the AI agent attempts to execute a task, it presents this cryptographic receipt to the network or a smart contract.
- Verification: The receiving party verifies the attestation against the user’s public key. If the signature is valid and the requested action falls within the parameters of the receipt, the transaction is allowed to proceed.
This structure ensures that the agent does not need to possess the user’s primary private keys. Instead, it carries a specialized “passport” that is only valid for the tasks the user has explicitly approved.
“Agents Propose, Humans Sign”
Attestations are the foundational layer of accountability in the machine-to-machine economy. Without these cryptographic delegation mechanisms, it would be extremely difficult for smart contracts to determine if a request is authorized. When these receipts are cryptographically secured (and, when stored on‑chain, effectively immutable), they provide a transparent audit trail of exactly what was authorized.
By using a signer to issue these receipts, you ensure that the authority ultimately remains in your hands. What’s more, verifying the terms of the attestation on a Secure Screen ensures that you are never blind signing a delegation. This combination of autonomous efficiency and hardware-backed proof ensures that, while your agents act quickly, you maintain full control over your digital assets: agents propose, but you still sign.
