Reject transactions from senders with deployed code

The five-minute read

One action, walked through

1. Open EIP 3607 and read the status line before the examples.
2. Write down the rule in one sentence. A fair version of that sentence is: Ethereum addresses are currently only 160 bits long.
3. Name the object that changes: EOA, USD, AMM.
4. 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 has to be true

• You are implementing EIP 3607 at the status the text itself states: Final.
• The object that has to change is EOA, USD, AMM. A neighbouring document with a similar name is not this one.
• Constants in the text can be superseded by a later fork. Cite the EIP number and the fork you mean.

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 does Reject transactions from senders with deployed code charge, reject, or redefine on the first touch versus a later one?
• Does a reverted subcall roll the change back?
• Can you point at the object in a client: EOA, USD, AMM?

Terms

EIP 3607

The public text titled Reject transactions from senders with deployed code.

Final

The document's own label for how finished the text is. It is not a market fact.

The problem the paper names

An underpriced or ambiguous EVM rule is not a feature. It is a block that takes longer than the gas limit claimed, or a client that disagrees about the result.

What the design proposes

• Ethereum addresses are currently only 160 bits long.
• This means it is possible to create a collision between a contract account and an Externally Owned Account (EOA) using an estimated 280 computing operations, which is feasible now given a large budget (ca.
• The fix in this EIP prevents the worst possible attack, where a safe looking contract (e.g.

How the mechanism is specified

• Taken from the specification, the next constraint is: This means it is possible to create a collision between a contract account and an Externally Owned Account (EOA) using an estimated 280 computing operations, which is feasible now given a large budget (ca.
• Locate EOA, USD, AMM in EIP 3607 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 gas or opcode change is not a throughput benchmark. It is a relative price and a validity rule.
• Constants in the text can be superseded by a later fork. Cite the EIP number and the fork you mean.
• 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 EIP 3607 when a pitch says 'Reject transactions from senders with deployed code' without saying whether the rule is consensus, policy, or an interface. The number is the citation. The pitch is not.
