Ethereum’s AI Moment: Which Projects Are Worth Watching Under the ERC-8004 Standard?

On January 28, the Ethereum mainnet will mark a major milestone with the official deployment of the ERC-8004 standard. This upgrade goes beyond a simple technical protocol release—it signals Ethereum’s ambition to evolve from a settlement layer for assets into a global application store and trust coordination layer for AI Agents.

Looking ahead, how will we discover new AI Agents? What will a decentralized, open AI ecosystem look like? And how will AI Agents handle payments for us?

ERC-8004, a new Ethereum technical standard first announced in the summer of 2025, aims to answer these questions.

This protocol was jointly developed by Marco De Rossi (AI Lead at MetaMask), Davide Crapis (AI Lead at the Ethereum Foundation), Jordan Ellis (Engineer at Google), and Erik Reppel (Head of Developer Platform Engineering at Coinbase), with extensive feedback and contributions from many other crypto companies and projects.

Why Was the ERC-8004 Standard Developed?

ERC-8004 enables developers and users to mint AI Agents just like NFTs, and delegate them using the ERC-721 standard. This makes AI Agents discoverable and allows on-chain reputation scoring for each Agent.

Traditionally, AI Agents have been second-class citizens on the internet. They lack bank accounts and identification, and are fully limited by centralized platform APIs. ERC-8004 addresses several key challenges:

1. Breaking the silo effect: Today’s AI plugins and Agents are stuck within private ecosystems like OpenAI or Google. ERC-8004 offers a neutral, public layer that isn’t owned by anyone, enabling Agents to exist and operate across platforms.

2. Machine credit society: Agents are black boxes—it’s hard to know if an automated financial Agent is trustworthy. With on-chain reputation records, negative reviews can’t be erased by vendors, and positive ratings are globally recognized.

3. Paying AI: While AI can’t open a bank account, it can have an Ethereum address. ERC-8004, together with the x402 protocol, allows AI to make micro-payments to autonomously purchase computing power, data, or hire other AI Agents, making them true independent economic entities.

De Rossi commented in an interview, “It may be too early to fully discuss business models. Even though x402 is clearly the best monetization channel for AI Agents, we should focus more on application scenarios rather than just infrastructure.”

It’s important to note that these Agents themselves won’t be stored on Ethereum. Running AI Agents directly on-chain is highly complex and requires significant overhead, so fully decentralized operation isn’t practical. However, ERC-8004 opens a middle ground for developers—between completely closed ecosystems and fully open, decentralized systems.

In this vision, users or businesses host AI Agents on their own devices or servers. Through 8004, they use blockchain to share their models with others—like an open app store—and receive ratings and feedback.

How Will the Ethereum Experience Change After the Upgrade?

With Agents gaining identities and wallets, Ethereum will shift from a speculative trading platform to a thriving machine-to-machine (A2A) marketplace.

1. AI Agent collaboration (A2A economy): Suppose you hire a travel planning Agent that isn’t skilled at finding cheap flights. It can discover a highly reputable ticket-hunting Agent on-chain and automatically pay stablecoins to outsource the task—all handled seamlessly in the background.

2. Fully automated asset management: You can authorize a hedging Agent to monitor your wallet. If the market experiences extreme volatility or security threats, it can automatically reallocate funds across different protocols using on-chain verification logic—no need to monitor your screen.

3. Decentralized AI store: You can browse and select Agents with various functions in an Agent browser, just like shopping in the App Store. Because these Agents exist as ERC-721 NFTs, you can buy, sell, lease, or stake those with high reputation and profitability.

For everyday users, the most immediate changes are the elimination of friction and a reduction in trust costs.

Previously, using various AI services meant registering multiple accounts, linking credit cards, and acquiring API keys. Now, your wallet is your passport. Agents settle directly via x402; you only need to pre-deposit some stablecoins—no more complicated subscription renewals.

Before, you couldn’t be sure if a third-party Agent would secretly transfer your funds or whether its advice was biased. Now, before using an Agent, you can view its on-chain “report card”—number of orders handled, success rate, user ratings. This trust is algorithmically guaranteed, not vendor-endorsed.

The most significant change is a shift from “tool interaction” to “intent interaction.” Previously, you might swap tokens on Uniswap and then deposit on Aave. Now, you can simply tell the Agent, “Help me deposit $1,000 in the highest-yield, lowest-risk place.” The Agent uses ERC-8004’s verification mechanism to find the optimal path and handles all complex operations for you.

To truly attract mainstream users, there’s a need for an AI Agent browser with a polished front end and integrated payment settlement. Several teams are already working on such products. However, making these products universally accessible—without platforms restricting visibility for certain Agent types—remains a major challenge.

Davide Crapis, AI Lead at the Ethereum Foundation, noted that Ethereum has unique advantages in securing and settling AI-to-AI interactions. “The ERC-8004 standard will launch on mainnet,” he said, adding that this release is just the beginning. “February is the genesis month—this will be critical.”

Which Projects Could Benefit Most from ERC-8004?

Ethereum Foundation engineer Binji takes a broader view, arguing that large-scale AI societies need a shared ledger of truth.

“Civilization scales because humans can engage in implicit trust; AI Agents cannot,” he said, describing blockchain as the only viable foundation for Agent societies. “ERC-8004 will solidify Ethereum and its L2s as such blockchains.”

This upgrade is widely expected to benefit a growing wave of AI-focused crypto projects—especially those building Agent infrastructure, orchestration layers, and on-chain marketplaces.

Analysts and developers generally divide the potential beneficiaries into two categories:

Infrastructure & Tools Layer

This includes platforms for Agent discovery, orchestration, and reputation tracking. Ecosystem trackers often highlight registries, settlement layers, interoperability, and scaling solutions for Ethereum and its Layer-2 networks.

x402’s Synergy Effects

The impact of ERC-8004 could be amplified by its close integration with x402.

x402 is a protocol for native, internet-based micro-payments between Agents. Built around HTTP 402 responses and stablecoin settlement, it enables Agents to pay directly for APIs, data, or computing resources—no accounts, API keys, or intermediaries required.

Market analysts believe ERC-8004’s portable reputation layer and x402’s frictionless payment mechanism together form an almost complete tech stack for decentralized AI commerce.

Some speculate that rising adoption could increase demand for tokens tied to Agent infrastructure and payment channels.

The global AI market is expected to surpass $1 trillion by 2031. Ethereum’s bet is on open, neutral infrastructure—seen as more promising than closed enterprise ecosystems. By anchoring identity, reputation, and settlement on-chain, ERC-8004 aims to position Ethereum as the “coordination layer” for autonomous Agents, not just an application platform.

Whether this vision leads to sustained network activity and value capture will become clear in the months following launch. For now, ERC-8004 stands as Ethereum’s most explicit attempt yet to claim space at the intersection of blockchain and AI.
