Minimal Proxy Contract
ERC 1167. Peter Murray , Nate Welch , Joe Messerman.
ERC 1167, Minimal Proxy Contract. To simply and cheaply clone contract functionality in an immutable way, this standard specifies a minimal bytecode implementation that delegates all calls to a known, fixed address.
Status in the source: Final. A reading of the public specification, not a copy of it and not a certification.
Minimal Proxy Contract is worth reading for the rule it actually adds: To simply and cheaply clone contract functionality in an immutable way, this standard specifies a minimal bytecode implementation that delegates all calls to a known, fixed address.

01 Claim ledger
What the paper is allowed to say
Each row is a sentence already in the study. The status is the same on every row: a model claim, not a live measurement.
Claim 01 · Paper model
The rule
To simply and cheaply clone contract functionality in an immutable way, this standard specifies a minimal bytecode implementation that delegates all calls to a known, fixed address.
Claim 02 · Paper model
What was already failing
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.
Claim 03 · Paper model
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.
Claim 04 · Paper model
What a builder should be able to point at
An implementation either constrains Minimal Proxy Contract or it is a different design.
02 Three cuts
Observation, model, falsifier
A desk does not stop at the summary. Each claim is cut three ways, using only this study's own assumptions and checks. Nothing here is a new figure.
01 The rule
Observation
What the study says
To simply and cheaply clone contract functionality in an immutable way, this standard specifies a minimal bytecode implementation that delegates all calls to a known, fixed address.
Model
What has to hold
The object that has to change is Minimal Proxy Contract. A neighbouring document with a similar name is not this one.
Falsifier
What would retire it
What does Minimal Proxy Contract charge, reject, or redefine on the first touch versus a later one?
02 What was already failing
Observation
What the study says
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.
Model
What has to hold
The object that has to change is Minimal Proxy Contract. A neighbouring document with a similar name is not this one.
Falsifier
What would retire it
Can you point at the object in a client: Minimal Proxy Contract?
03 What the number does not mean
Observation
What the study says
The source marks this final. That is a statement about the text, not a promise that every wallet or node has shipped it.
Model
What has to hold
You are implementing ERC 1167 at the status the text itself states: Final.
Falsifier
What would retire it
Can you point at the object in a client: Minimal Proxy Contract?
04 What a builder should be able to point at

An implementation either constrains Minimal Proxy Contract or it is a different design.

03 Sequence
One action, as an operating tape
- 01Open ERC 1167 and read the status line before the examples.
- 02Write down the rule in one sentence. A fair version of that sentence is: To simply and cheaply clone contract functionality in an immutable way, this standard specifies a minimal bytecode implementation that delegates all calls to a known, fixed address.
- 03Name the object that changes: Minimal Proxy Contract.
- 04Ask what an old client, an old contract, or an offline counterparty does. If the document is silent, the silence is part of the design.
04 Load-bearing
The argument, and where a pitch drops it
What the text is allowed to settle
The cut
Ethereum Request for Comment 1167 can settle the shape of Minimal Proxy Contract. It cannot settle whether a later client, a later fork, or a later wallet still does this.
Why it carries weight
If this cut is skipped, the paper's name is being used without the mechanism that makes the name mean anything.
Where it is dropped
Constants in the text can be superseded by a later fork. Cite the EIP number and the fork you mean.
What this page will not pretend
The cut
There is no benchmark, no adoption number, and no claim that the mechanism is safe outside the assumptions written in the source.
Why it carries weight
If this cut is skipped, the paper's name is being used without the mechanism that makes the name mean anything.
Where it is dropped
A gas or opcode change is not a throughput benchmark. It is a relative price and a validity rule.

06 Divergence
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.
A later client, parameter set, or reward formula is a different object. Cite this paper for the mechanism. Cite a primary release for the network. This desk has not re-run the proof.

08 Anatomy
The paper, in the order a builder needs
The problem it 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
- To simply and cheaply clone contract functionality in an immutable way, this standard specifies a minimal bytecode implementation that delegates all calls to a known, fixed address.
- By standardizing on a known minimal bytecode redirect implementation, this standard allows users and third party tools (e.g.
- Etherscan) to (a) simply discover that a contract will always redirect in a known manner and (b) depend on the behavior of the code at the destination contract as the behavior of the redirecting contract.
How the mechanism is specified
- Taken from the specification, the next constraint is: By standardizing on a known minimal bytecode redirect implementation, this standard allows users and third party tools (e.g.
- Locate Minimal Proxy Contract in ERC 1167 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 the desk still reads it
Use ERC 1167 when a pitch says 'Minimal Proxy Contract' without saying whether the rule is consensus, policy, or an interface. The number is the citation. The pitch is not.
