ERC-8004 x402 Deep Dive
so you like agents. but you can't trust agents. at least not until you know your agents are registered with the ERC-8004 standard.
ERC-8004 is the
@ethereum standard for trustless agents - a framework for registering, discovering, and verifying autonomous agents on-chain.
it gives each agent a verifiable identity, reputation, and validation record, making interactions safer and more transparent.
with ERC-8004, agents can build trust, collaborate, and transact across networks without centralized gatekeepers.
here are a few apps already building on ERC-8004:
1. OpenServ
@openservai
Openserv is a multi-agent orchestration platform, and you can build agentic workflows for your swarms on the platform.
integrating the ERC-8004 standard is particularly important here, as OpenServ workflows can be registered as on-chain agent identities.
with it agents will mint ERC-721 entries on the Identity Registry, exposing their metadata, MCP endpoints, and payment requirements. additionally, x402-based payment proofs will allow users to pay on-chain for workflow execution and attach verifiable payment references to their interactions.
this will make OpenServ agents discoverable, callable, and monetizable through the ERC-8004 standard.
2. Unibase
@Unibase_AI
Unibase is a memory layer for agents. agents built on bitagent will now come with verifiable on-chain identity, permanent memory, and be able to transact with x402.
erc-8004 is important for a memory layer like unibase as you would want to be able to verify on-chain proof and traceability.
Unibase is also one of the first apps on
@BNBCHAIN building with x402 and ERC-8004.
3. ChaosChain
@Ch40sChain
ChaosChain is the accountability protocol for the autonomous AI economy.
with one SDK setup, you can your agents can now browse through ERC-8004 registries for identity, reputation, and validation.
you can also build verifiable, monetizable AI agents with on-chain identity with the SDK.
