Purpose bound money

The five-minute read

One action, walked through

1. Open ERC 7291 and read the status line before the examples.
2. Write down the rule in one sentence. A fair version of that sentence is: A Purpose Bound Money (PBM) token is a wrapper around an ERC-1155 token that can be used for a limited activity.
3. Name the object that changes: PBM, SHOULD.
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 7291 at the status the text itself states: Final.
• The object that has to change is PBM, SHOULD. A neighbouring document with a similar name is not this one.
• A token standard does not collateralise itself.

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

• Who loses money if the assumption in Purpose bound money is wrong?
• Is redemption specified, or only a transfer function?
• Which terms are actually defined: PBM, SHOULD?

Terms

ERC 7291

The public text titled Purpose bound money.

Final

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

The problem the paper names

A claim that something is a dollar, a loan, or a vault is a claim about who is paid when the price moves. The interface is not that claim.

What the design proposes

• A Purpose Bound Money (PBM) token is a wrapper around an ERC-1155 token that can be used for a limited activity.
• This proposal outlines a smart contract interface that builds upon the ERC-1155 standard to implement the purpose bound money (PBM) concept: - A PBM consists of a PBM wrapper and the digital money token it wraps.
• A digital money token (e.g., stablecoins, central bank digital currencies, tokenized bank deposits, and similar instruments) serves as a store of value (abbreviated as "sov").

How the mechanism is specified

• Taken from the specification, the next constraint is: This proposal outlines a smart contract interface that builds upon the ERC-1155 standard to implement the purpose bound money (PBM) concept: - A PBM consists of a PBM wrapper and the digital money token it wraps.
• Locate PBM, SHOULD in ERC 7291 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

• Nothing on this page is a yield, a redemption promise, or an offer of credit.
• A token standard does not collateralise itself.
• 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 7291 when a pitch says 'Purpose bound money' without saying whether the rule is consensus, policy, or an interface. The number is the citation. The pitch is not.
