Token Standard

The five-minute read

One action, walked through

1. Open ERC 777 and read the status line before the examples.
2. Write down the rule in one sentence. A fair version of that sentence is: Standard interfaces and behaviors for token contracts.
3. Name the object that changes: Token Standard.
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 777 at the status the text itself states: Final.
• The object that has to change is Token Standard. A neighbouring document with a similar name is not this one.
• The standard does not enforce royalties, identity, or a price. If the transfer function does not check it, the chain will not.

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

• Which function in Token Standard actually moves or approves value?
• What happens on a callback, a zero amount, or a contract recipient that rejects?
• Which names does the text commit to: Token Standard?

Terms

ERC 777

The public text titled Token Standard.

Final

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

The problem the paper names

A token that each contract invents from scratch does not transfer, approve, or display in any other contract. The cost of a shared interface is that the interface's holes become everyone's holes.

What the design proposes

• Standard interfaces and behaviors for token contracts.
• This standard defines a new way to interact with a token contract while remaining backward compatible with [ERC-20].
• It defines advanced features to interact with tokens.

How the mechanism is specified

• Taken from the specification, the next constraint is: This standard defines a new way to interact with a token contract while remaining backward compatible with [ERC-20].
• Locate Token Standard in ERC 777 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

• An application standard is not consensus. A contract can ignore it and still be a valid account.
• The standard does not enforce royalties, identity, or a price. If the transfer function does not check it, the chain will not.
• 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 777 when a pitch says 'Token Standard' without saying whether the rule is consensus, policy, or an interface. The number is the citation. The pitch is not.
