No Intermediary NFT Trading Protocol
ERC 6105. 5660-eth , Silvere Heraudeau , Martin McConnell , Abu , Wizard Wang.
ERC 6105, No Intermediary NFT Trading Protocol. A marketplace functionality to ERC-721 to enable non-fungible token trading without relying on an intermediary trading platform.
Status in the source: Final. A reading of the public specification, not a copy of it and not a certification.
No Intermediary NFT Trading Protocol is worth reading for the rule it actually adds: A marketplace functionality to ERC-721 to enable non-fungible token trading without relying on an intermediary trading platform.
The five-minute read
The rule
A marketplace functionality to ERC-721 to enable non-fungible token trading without relying on an intermediary trading platform.
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, BAYC or it is a different design.
One action, walked through
- Open ERC 6105 and read the status line before the examples.
- Write down the rule in one sentence. A fair version of that sentence is: A marketplace functionality to ERC-721 to enable non-fungible token trading without relying on an intermediary trading platform.
- Name the object that changes: NFT, BAYC.
- 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 6105 can settle the shape of No Intermediary NFT Trading Protocol. 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 6105 at the status the text itself states: Final.
- The object that has to change is NFT, BAYC. 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 No Intermediary NFT Trading Protocol 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, BAYC?
Terms
- ERC 6105
- The public text titled No Intermediary NFT Trading Protocol.
- 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
- A marketplace functionality to ERC-721 to enable non-fungible token trading without relying on an intermediary trading platform.
- At the same time, creators may implement more diverse royalty schemes.
- Most current NFT trading relies on an NFT trading platform acting as an intermediary, which has the following problems: 1.
How the mechanism is specified
- Taken from the specification, the next constraint is: At the same time, creators may implement more diverse royalty schemes.
- Locate NFT, BAYC in ERC 6105 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 6105 when a pitch says 'No Intermediary NFT Trading Protocol' without saying whether the rule is consensus, policy, or an interface. The number is the citation. The pitch is not.
