On Oct. 7, Ethereum (CRYPTO: ETH) co-founder Joseph Lubin said on CNBC that while AI might offer creativity and expertise, it can’t create trust, which blockchains like his can help to supply. In his view, AI and crypto will thus end up merging, becoming the system where programmatic work can be commissioned, completed, and compensated.
There’s a little bit of evidence that Lubin’s world is already starting to peek into existence. Here’s what it’d mean for Ethereum if that continues.
Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a “Double Down” signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same “Total Conviction” signal is flashing for a company 1/100th the size of Nvidia. Continue »

Today, one of Ethereum’s biggest contributions to the AI-in-crypto segment is ERC-8004, a new standard for blockchains that calls for tracking the identities and reputations of AI agents. As of Oct. 20, Ethereum hosted 72,028 registered AI agents, about 9.2% of the 783,881 agents registered under ERC-8004.
It also holds the most capital, which agents will likely need to use, with $49.6 billion in capital stored in its decentralized finance (DeFi) apps, and more than $144 billion in stablecoins. Liquidity in DeFi services and stablecoins are both big parts of what makes a cryptocurrency valuable to agents moving money, as the size of those footprints determines how much capital is available for the ecosystem to use for services and products.
Are AI agents actually creating real value on Ethereum yet?
Today, the agent economy is largely theoretical.
Monthly agent payments over x402, a standard for paying in stablecoins, peaked at $20.5 million in November 2025, and then fell to $263,863 in September 2026. Meanwhile, Ethereum collected $17.7 million in transaction fees in the 30 days ending on Oct. 20. Agents supplied almost none of that, since Ethereum’s main chain had settled just 644 agent payments as of Oct. 20.
Still, there are signs Lubin’s vision is taking shape. Ethereum hosted about 32,343 registered agents as of May 13 of this year, so its count has more than doubled in five months.
Moving forward, expect its capital to attract more agents that are native to other networks, and expect more developers to launch their agents on Ethereum. Over the next five years, the sum of agents could explode, and with it, the frequency and amount of their transactions, as well as the diversity of their needs and offered services.
