Reid Hoffman Says AI Agents Need NFTs to Build Trust Across the Internet
LinkedIn co-founder and Greylock partner Reid Hoffman said on May 6 that non-fungible tokens may be due for a comeback, not as speculative collectibles, but as identity infrastructure for autonomous AI agents. Hoffman said agents operating on behalf of humans across the open internet will need cryptocurrency-based identity and trust systems to transact reliably.
The argument repositions NFTs as a functional technology rather than a financial instrument, arriving at a moment when agentic AI has moved from concept to active deployment.
What Hoffman Argued
Hoffman made the remarks in a CoinDesk interview published May 6. He said the core problem is that AI agents acting autonomously on behalf of users have no standardized way to prove who they are, who controls them, or whether their instructions are trustworthy.
Current web identity systems were built for human users. They rely on cookies, login sessions, and behavioral signals that agents either cannot produce or can trivially fake.
Hoffman’s argument is that NFTs, as unique verifiable objects on a public blockchain, could give each agent a persistent, auditable identity credential. Any counterparty receiving a request from an agent could verify its credential on-chain before executing a transaction.

Why NFTs Specifically
An NFT, a non-fungible token, is a unique digital record on a blockchain that cannot be duplicated or reassigned without a cryptographic transaction.
Unlike a username or password, an NFT-based credential carries a full history of ownership and transfer. That history is publicly verifiable and tamper-resistant.
For an AI agent, an NFT identity would record which human or organization deployed it, what permissions it was granted, and when those permissions changed. Hoffman argued this creates an accountability chain that neither session-based web identity nor centralized API keys can provide.
The blockchain layer handles verification without requiring any counterparty to trust a central registry.

Background
NFTs peaked as a speculative asset class in 2021 and 2022, with total trading volume reaching $25 billion in 2021 alone before collapsing sharply through 2023. The asset class became associated with digital art, profile pictures, and high-profile frauds, which obscured its underlying technical utility as a method for recording unique on-chain ownership.
The agentic AI wave of 2025 and 2026 has revived academic and industry interest in blockchain-based identity, with several projects building credential layers for autonomous software. Anchorage Digital launched an agentic banking product in May 2026 designed to give AI agents access to financial rails, which directly raised the question of how those agents authenticate themselves to financial counterparties.
Hoffman’s comments connect those two threads into a single argument for NFT-based identity as the missing infrastructure layer.

What Would Have to Change
The practical gap between Hoffman’s argument and a deployed system is significant. NFT minting costs on most blockchains, while lower than in 2021, still introduce friction for applications issuing millions of agent credentials.
Standardization across chains remains absent. No major platform has committed to recognizing NFT-based agent credentials as valid authentication. Ethereum (ETH)‘s account abstraction proposals and several emerging identity protocols offer partial solutions, but none has reached the adoption threshold needed to make the argument practical at scale.
Hoffman’s contribution is framing rather than engineering. He is positioning the NFT infrastructure that already exists as a candidate for a problem that has not yet been formally solved.
What Comes Next
The agent identity problem will force a solution whether or not NFTs win the standard.
The volume of autonomous transactions is growing fast. Financial institutions, APIs, and web services will need a way to verify agent identity before the transaction layer breaks under unverifiable requests.
NFTs are one candidate. Decentralized identifiers, a W3C standard for blockchain-anchored credentials, are another.
Centralized identity providers could also issue agent tokens using existing OAuth infrastructure. Hoffman’s endorsement raises the profile of the NFT option.
It does not guarantee adoption. The next inflection point is likely a major AI platform or financial institution committing to a specific technical standard, which would force the rest of the market to align or fragment.
