Agent Coordination Framework
ERC 8001. Kwame Bryan.
ERC 8001, Agent Coordination Framework. ERC-8001 defines a minimal, single-chain primitive for multi-party agent coordination.
Status in the source: Final. A reading of the public specification, not a copy of it and not a certification.
Agent Coordination Framework is worth reading for the rule it actually adds: ERC-8001 defines a minimal, single-chain primitive for multi-party agent coordination.
The five-minute read
The rule
ERC-8001 defines a minimal, single-chain primitive for multi-party agent coordination.
What was already failing
A signature that does not commit to what the user saw can be replayed into a different spend, a different chain, or a different message.
What the number does not mean
The source marks this final. That is a statement about the text, not a promise that every wallet or node has shipped it.
What a builder should be able to point at
An implementation either constrains MEV, MUST, SHOULD or it is a different design.
One action, walked through
- Open ERC 8001 and read the status line before the examples.
- Write down the rule in one sentence. A fair version of that sentence is: ERC-8001 defines a minimal, single-chain primitive for multi-party agent coordination.
- Name the object that changes: MEV, MUST, SHOULD.
- Ask what an old client, an old contract, or an offline counterparty does. If the document is silent, the silence is part of the design.
The argument, unpacked
What the text is allowed to settle
Ethereum Request for Comment 8001 can settle the shape of Agent Coordination Framework. It cannot settle whether a later client, a later fork, or a later wallet still does this.
What this page will not pretend
There is no benchmark, no adoption number, and no claim that the mechanism is safe outside the assumptions written in the source.
What has to be true
- You are implementing ERC 8001 at the status the text itself states: Final.
- The object that has to change is MEV, MUST, SHOULD. A neighbouring document with a similar name is not this one.
- Wallet support is not the same as consensus validity.
What happened after the paper
The source marks this final. That is a statement about the text, not a promise that every wallet or node has shipped it. Later documents can narrow, replace, or ignore this one. Cite the number you mean.
What to check before you use the idea
- What is covered by the signed bytes in Agent Coordination Framework?
- Can the same signature be replayed on another chain, account, or message?
- Which primitive does the text require: MEV, MUST, SHOULD?
Terms
- ERC 8001
- The public text titled Agent Coordination Framework.
- Final
- The document's own label for how finished the text is. It is not a market fact.
The problem the paper names
A signature that does not commit to what the user saw can be replayed into a different spend, a different chain, or a different message.
What the design proposes
- ERC-8001 defines a minimal, single-chain primitive for multi-party agent coordination.
- An initiator posts an intent and each participant provides a verifiable acceptance attestation.
- Once the required set of acceptances is present and fresh, the intent is executable.
How the mechanism is specified
- Taken from the specification, the next constraint is: An initiator posts an intent and each participant provides a verifiable acceptance attestation.
- Locate MEV, MUST, SHOULD in ERC 8001 and apply it to one transaction or call.
- Then check the failure the class of rule always has: a node that did not upgrade, a reverted call, a replayed signature, or a peer that does not speak the message.
What this page does not treat as proven
- A signature scheme is not a privacy system. It hides the signer only if the protocol says so.
- Wallet support is not the same as consensus validity.
- The source marks this final. That is a statement about the text, not a promise that every wallet or node has shipped it.
Why a venture studio still reads it
Use ERC 8001 when a pitch says 'Agent Coordination Framework' without saying whether the rule is consensus, policy, or an interface. The number is the citation. The pitch is not.
