Ethereum’s AI Turning Point: What to Watch After the ERC-8004 “Trustless Agents” Standard
Ethereum’s AI Turning Point: What to Watch After the ERC-8004 “Trustless Agents” Standard
On January 28, 2026, the Ethereum ecosystem is once again testing a bold thesis: Ethereum is not only a settlement layer for assets, but also a neutral coordination layer for autonomous software. Multiple community reports indicate that the canonical ERC-8004 (“Trustless Agents”) registry contracts are approaching a mainnet rollout window—though it’s important to note that an ERC standard is not a consensus upgrade and does not require a hard fork; it becomes real when teams deploy and adopt compatible contracts and tooling. (odaily.news)
If this direction sticks, the next question won’t be “Which dApp should I use?” but rather:
- Which AI Agent should I delegate a task to?
- How do I discover agents in an open market?
- How do I evaluate trust, avoid Sybil reputations, and verify outcomes?
- And when an agent needs to pay another agent (or pay for an API), what does autonomous payment look like onchain?
This is the promise (and the tension) behind ERC-8004. (eips.ethereum.org)
1) From “Asset Settlement” to “Agent Coordination”
The 2025–2026 trend line is clear: user intent is moving up the stack.
In DeFi, we saw intents, automation, and “one-click” strategies reduce manual steps. In AI, we saw tool standards like Model Context Protocol (MCP) and inter-agent messaging protocols start to unify how models and tools interact. But a missing piece remains: open discovery and trust across organizations.
ERC-8004 tries to fill that gap by giving agents portable identity, public reputation signals, and verification hooks—all on credibly neutral infrastructure. (eips.ethereum.org)
2) What ERC-8004 Actually Standardizes (and What It Doesn’t)
ERC-8004 introduces three lightweight onchain registries: (eips.ethereum.org)
Identity Registry (Discovery Starts Here)
- Agents register into an ERC-721-based registry (yes, agents become NFT-like identities).
- The
tokenURIpoints to an Agent Card / registration file (typically off-chain), which describes capabilities, endpoints, and supported trust models. (eips.ethereum.org)
Why this matters: it makes “who is the agent?” queryable, transferable, and indexable using familiar Ethereum primitives.
Reputation Registry (Signals, Not “One Score to Rule Them All”)
- Users (or other agents) can post feedback signals.
- Aggregation can be off-chain or on-chain depending on the use case; the standard focuses on a shared interface rather than mandating a monopoly scoring model. (eips.ethereum.org)
Validation Registry (Proof Hooks)
- A generic framework to request or record validation: re-execution, staking guarantees, zkML proofs, TEE attestations, or other schemes.
- The core idea: trust should scale with value at risk. (eips.ethereum.org)
What ERC-8004 explicitly does not standardize: payments
Payments are intentionally treated as an orthogonal problem, so the ecosystem can plug in different rails (stablecoins, L2s, micropayments, etc.). (eips.ethereum.org)
3) In a World of Agent Markets, How Do We “Find the Right Agent”?
Discovery in an open AI economy is not “App Store search.” It’s closer to a blend of:
- onchain identity indexing (Identity Registry events),
- off-chain crawlers and directories,
- and reputation/validation overlays per domain.
This is where ERC-8004’s design is practical: it keeps the base layer small, so many competing “agent search engines” can exist—without any single gatekeeper.

4) How Agents Pay: Why x402 Is Showing Up Everywhere
In 2025, stablecoins became the default settlement primitive for internet-native commerce. In 2026, the open question is: how do agents pay for services automatically without accounts, subscriptions, or manual checkout flows?
One of the most discussed answers is x402—an open protocol developed by Coinbase that revives the HTTP 402 Payment Required flow so API calls can request payment and clients (including agents) can pay programmatically. (docs.cdp.coinbase.com)
Key reading:
Why this matters for Web3 users: the next wave of “transactions” may not start in a wallet UI. They may start as agent-to-agent HTTP requests that settle in stablecoins—then leave behind payment proofs that can feed back into reputation.
5) ERC-8004 Ecosystem: Projects and Directions Worth Watching
Below are categories (and early examples) that matter more than any single token narrative.
A) Official specification + reference community
These are the “source of truth” layers where breaking changes, schemas, and interoperability norms will crystallize:
B) Agent creation SDKs + metadata persistence
Agent identities become useful only if their Agent Cards and metadata remain durable and verifiable over time. A notable direction here is pairing agent identity with verifiable storage:
- Filecoin Foundation highlights the ERC-8004 builder community using Filecoin Pin / Onchain Cloud for agent identity metadata and discovery workflows, including an Agent0 SDK referenced in its ecosystem explorer entry.
See: Filecoin Foundation — ERC-8004 ecosystem page (fil.org)
C) Directories, explorers, and “Agent SEO”
Just like token lists and block explorers became critical UX infrastructure, agent registries will become a battleground for distribution.
What to watch for in an agent directory:
- can it verify Identity Registry provenance?
- does it show reputation context (who rated whom, under what task scope)?
- does it surface validation proofs (zkML/TEE/re-execution)?
D) Validation networks and attestation rails
ERC-8004 validation is a hook, so projects that already specialize in attestations can become key building blocks.
One widely used attestation primitive in Ethereum is Ethereum Attestation Service (EAS), which is already referenced in community discussions as a practical layer for persistent proofs.
See: Ethereum Attestation Service (ethereum-magicians.org)
E) Cross-chain agent identity (CAIP-10)
Agents won’t live on one chain. Even if their “home identity” starts on Ethereum, execution and payments may happen on L2s or other networks.
ERC-8004’s broader ecosystem frequently references CAIP identifiers for chain-agnostic account formatting:
Practical implication: an agent can keep a consistent identity anchor while operating across multiple execution environments.
6）用户真正关心的问题（注重安全，而非炒作）
如果智能代理具备发起操作和付款的能力，那么用户面临的风险就从「点错按钮」转变为「赋予了错误的权限」。
面向早期用户的实用安全清单：
-
按风险等级分离资金
对于低风险的自动化操作，使用一个小额热钱包；长期持有的资产应隔离存放。 -
优先使用明确的权限和支出上限
避免无限授权；尽可能采用范围明确的权限设置。 -
根据具体情境判断代理声誉
一个「研究型高声誉代理」未必适用于资产托管或交易操作。 -
验证身份来源的可靠性
仅信任身份清晰注册，且其代理卡（Agent Card）端点与你预期一致的代理。
7）OneKey 在代理时代的定位
随着人工智能代理从「聊天助手」演变成「经济行为者」，最关键的安全边界依然不变：私钥不应存在于始终在线的环境中。
硬件钱包如 OneKey，可以成为一个实用的控制节点，例如：
- 确认代理建议的高价值转账
- 将日常代理支出与长期资产储存区分开
- 保持签名密钥离线，同时依然参与链上协作
换句话说：即便你的工作流程由代理主导，关键资产的最终授权 仍可由人类掌控。
结语
ERC-8004 最应被理解为一种信任基础设施：它并不试图取代 MCP（多方计算协议）、A2A（代理间通信）或支付协议，而是为它们提供一个中立的身份、声誉和验证层，可被自由组合并公开协作。
如果以太坊在这一领域取得成功，那么「发现一个新 dApp」的体验，可能会转变为「选择一个代理」，而下一次加密用户体验的跃迁，也许不再是界面的变化，而是聚焦于委托、验证与编程式支付。
