ERC 6059. Bruno Škvorc , Cicada , Steven Pineda , Stevan Bogosavljevic , Jan Turk.
ERC 6059, Parent-Governed Nestable Non-Fungible Tokens. The Parent-Governed Nestable NFT standard extends ERC-721 by allowing for a new inter-NFT relationship and interaction.
Status in the source: Final. A reading of the public specification, not a copy of it and not a certification.
Parent-Governed Nestable Non-Fungible Tokens is worth reading for the rule it actually adds: The Parent-Governed Nestable NFT standard extends ERC-721 by allowing for a new inter-NFT relationship and interaction.
The five-minute read
The rule
The Parent-Governed Nestable NFT standard extends ERC-721 by allowing for a new inter-NFT relationship and interaction.
What was already failing
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 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.
What a builder should be able to point at
An implementation either constrains NFT, EOA or it is a different design.
One action, walked through
- Open ERC 6059 and read the status line before the examples.
- Write down the rule in one sentence. A fair version of that sentence is: The Parent-Governed Nestable NFT standard extends ERC-721 by allowing for a new inter-NFT relationship and interaction.
- Name the object that changes: NFT, EOA.
- 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 the text is allowed to settle
Ethereum Request for Comment 6059 can settle the shape of Parent-Governed Nestable Non-Fungible Tokens. It cannot settle whether a later client, a later fork, or a later wallet still does this.
What this page will not pretend
There is no benchmark, no adoption number, and no claim that the mechanism is safe outside the assumptions written in the source.
What has to be true
- You are implementing ERC 6059 at the status the text itself states: Final.
- The object that has to change is NFT, EOA. 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 Parent-Governed Nestable Non-Fungible Tokens 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: NFT, EOA?
Terms
- ERC 6059
- The public text titled Parent-Governed Nestable Non-Fungible Tokens.
- 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
- The Parent-Governed Nestable NFT standard extends ERC-721 by allowing for a new inter-NFT relationship and interaction.
- At its core, the idea behind the proposal is simple: the owner of an NFT does not have to be an Externally Owned Account (EOA) or a smart contract, it can also be an NFT.
- The process of nesting an NFT into another is functionally identical to sending it to another user.
How the mechanism is specified
- Taken from the specification, the next constraint is: At its core, the idea behind the proposal is simple: the owner of an NFT does not have to be an Externally Owned Account (EOA) or a smart contract, it can also be an NFT.
- Locate NFT, EOA in ERC 6059 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 6059 when a pitch says 'Parent-Governed Nestable Non-Fungible Tokens' without saying whether the rule is consensus, policy, or an interface. The number is the citation. The pitch is not.
