Revised Ethereum Smart Contract Packaging Standard (EthPM v3)

The five-minute read

One action, walked through

1. Open ERC 2678 and read the status line before the examples.
2. Write down the rule in one sentence. A fair version of that sentence is: A data format describing a smart contract software package.
3. Name the object that changes: JSON, IPFS, snake_case.
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 ERC 2678 at the status the text itself states: Final.
• The object that has to change is JSON, IPFS, snake_case. 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 Revised Ethereum Smart Contract Packaging Standard (EthPM v3)?
• Can the same signature be replayed on another chain, account, or message?
• Which primitive does the text require: JSON, IPFS, snake_case?

Terms

ERC 2678

The public text titled Revised Ethereum Smart Contract Packaging Standard (EthPM v3).

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

• A data format describing a smart contract software package.
• This EIP defines a data format for package manifest documents, representing a package of one or more smart contracts, optionally including source code and any/all deployed instances across multiple networks.
• Package manifests are minified JSON objects, to be distributed via content addressable storage networks, such as IPFS.

How the mechanism is specified

• Taken from the specification, the next constraint is: This EIP defines a data format for package manifest documents, representing a package of one or more smart contracts, optionally including source code and any/all deployed instances across multiple networks.
• Locate JSON, IPFS, snake_case in ERC 2678 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 2678 when a pitch says 'Revised Ethereum Smart Contract Packaging Standard (EthPM v3)' without saying whether the rule is consensus, policy, or an interface. The number is the citation. The pitch is not.
