Ethereum is launching ERC-8004, enabling AI agents to interact globally without intermediaries, enhancing identity and reputation verification.
Ethereum is preparing to launch the ERC-8004 upgrade on its mainnet, facilitating interactions between AI agents and organizations.
ERC-8004 is about to go live on mainnet.
This upgrade enables discovery and portable reputation for AI agents, allowing them to interact seamlessly across organizations while maintaining credibility.

This upgrade will enable the discovery of digital assistants and their services without a central authority, while providing them with a reputation that exists independently of any single platform.
ERC-8004 will verify:
- the identity of AI agents;
- their historical activities;
- their trustworthiness.
These advancements will create a global marketplace for AI services, allowing assistants to communicate directly with one another without needing intermediaries.
Starting in August 2025, each AI agent will be assigned a unique identifier through a dedicated registry contract, ensuring compatibility with existing infrastructures and facilitating asset transfers.
Trust models for AI agents will be classified by security levels, ranging from low-risk tasks like ordering food to high-risk activities such as medical diagnoses.
The exact activation date for this upgrade remains unconfirmed, but Marco De Rossi, co-author of the standard and head of AI at MetaMask, has indicated January 29, 2026, as a potential date.
“Ethereum provides a unique platform that ensures security and transactional integrity in interactions between AI systems,” stated Davide Crapis, head of the AI department at the Ethereum Foundation.
Enhancing Identity, Reputation, and Validation
ERC-8004 will introduce three registries aimed at enhancing trust in AI agents, compatible with both the mainnet and Layer 2 protocols.
The identity registry will provide each agent with a portable, censorship-resistant identifier, while compatibility with NFT standards will allow easy profile transfers across applications.
The reputation registry will facilitate signed reviews from users, generating ratings for digital assistants.
The validation registry will manage audits: agents will seek verification of their actions, with the results recorded on the blockchain.
AI Management of Financial Transactions
There is growing discourse within the crypto community about the potential for AI agents to handle financial transactions autonomously, including purchases and payments.
Ethereum co-founder Vitalik Buterin predicts that within the next 5-10 years, AI will be capable of managing numerous micropayments, although full automation for larger transactions poses risks.
“AI is vulnerable to attacks, making it suitable for small transactions. However, it can also be a risk management tool for larger transfers, helping to identify suspicious activities,” he explained.
Paxos sees AI agents as a significant force for the stablecoin market, suggesting that AI could help manage the fragmentation seen across jurisdictions and token models.
AI algorithms could quickly navigate various platforms and assets, optimizing transaction conditions.
“This fragmentation could transform into an optimization factor, allowing AI to enhance liquidity flows to the most efficient issuers, potentially lowering fees and fostering competition,” commented Bhav Kotecha, co-founder of Paxos.
Galaxy Digital CEO Mike Novogratz anticipates that neural networks will become major users of stablecoins, enabling users to delegate everyday purchases and payments to AI agents.
Investor Kevin O’Leary emphasized the revolutionary potential of AI and blockchain, predicting that AI will autonomously handle retail transactions while blockchain processes the payments.
Innovations for the future AI economy are already underway, with Coinbase recently launching a Payments MCP system to facilitate cryptocurrency access for language models like Anthropic's Claude and Google's Gemini.
PayPal plans to adopt the Agentic Commerce Protocol (ACP) and OpenAI's Instant Checkout feature, enabling purchases through ChatGPT.
The ACP will serve as an open standard for sellers to list products in AI applications, allowing users to buy through agents, while Instant Checkout allows seamless order confirmation and payment processing within ChatGPT.
Additionally, the Quack AI team has introduced x402 BNB, a tool designed to streamline transactions by reducing multiple steps into a single signature process, thus enabling gasless transactions that are verifiable and auditable.
Ethereum's Fee Situation
Currently, Ethereum network fees have fallen to their lowest levels since May 2017, despite a record number of transfers occurring in January.
The network achieved an average of nearly 2.5 million transactions over a week, double the amount from the previous year, following a surge in on-chain activity that began in mid-December after a period of decline. Recent upgrades have improved the network's scalability.
- Activation of the Fusaka upgrade in early winter;
- Fork of the Blob Parameter-Only on January 7, increasing the BLOB object limit in blocks from 15 to 21.
In January, Glassnode also reported a doubling in the retention rate of active users on the Ethereum network.
