Just an update on where I'm at. I'm still stuck. I've been testing with the 0N1 Force collection. It seems if you do a collection offer there are no filters (which makes this easy to test with), therefore I'm assuming a collection offer is just simply "collection-wide" and the merkle tree would consist of all token IDs when built. So, I built a merkle tree with token IDs 1 - 7777 (inclusive), and upon generating proofs for one of the IDs, it seems I can get 4 of them to match, and the other 9 do not match. The root hash also does not match. It's pretty cool that 4 do match, I think that means I'm on the right track, but not there yet. At this point, I think I've exhausted ideas that make sense, and I've just been guessing at what could possibly be different. Why would the tree for a "collection-wide" offer have something other than all tokens in the collection? Perhaps it excludes tokens that are "locked" on OS? |

Hey @shea851, If we're not properly returning the proof that's on us. You shouldn't be expected to generate the proof yourself as we don't give you the list of valid identifiers either. This is something Opensea has to support returning from the REST endpoint. |

It's actively being worked on, next week should be reasonable |

If possible, could seaport include a full example on how to fulfill an advanced order using the criteria proofs? |

Hey @sunwrobert are there any updates on this being provided to us from the REST API? @warneracw21 @shea851 have you guys made any progress on your end? |

Hey, sorry things are a bit on hold now as we go through some restructuring. |

is it updated now ? I still cant calculate the merkle proof. It returns an empty array |

Hi, how exactly do you generate merkle tree for a range? say 1-10000? I'm not generating the correct root |

Is it not possible to let us know the range for generating the merkle tree? |

Hey all, are there any updates on this matter? What I've noticed is sometimes the My question is actually what to do when the value is returned as '0'. When I like to fulfil a particular order which is an offer for a collection valid for any trait (hence the What to do in these cases? Is it required to supply a proof ourselves? How does that relate to the signature provided with the order? Can a consideration be extended not only for tipping, but also for modifying the proof? Many head scratching questions are floating... |

You pass in an empty array basically |

No news about the implementation in the endpoint ? |

Why not just provide the information on how to calculate the tree instead of providing an endpoint? |

@sunwrobert why are you not helping any of us ? This doesnt look good. You are literally ignoring everything and just gave attention to the older ones 7-8months ago |

Same issue for me. After 7 months there is still no update. I can't believe this |

the seaport api endpoint for the trair and collection based offers are literally useless without providing us this merkle proof information |

Everything is in their github, you just have to set up the merkle using their criteria code, and everything will work (I did it) |
Beta Was this translation helpful? Give feedback.

However it is the case, the criteria is functional as I can accept collections offers, the code is the same as theirs. |

could you please share the functional code for us all |

could you show me which code works please ? Im really waiting for it for days now as the creators dont care at all helping the community |

Hi,
Recently, criteria based offers began to show up from the offers API.
It seems that in order to fulfill an offer, an identifier must be supplied (token ID I'm assuming), as well as merkle proofs that this is a valid leaf in the tree. It also seems we are given the tree root.
I don't believe I can build a tree with just the root. I think the root is given so we can validate that the tree we built is a match.
I am not sure how to obtain these merkle proofs. My guess is that I would need to build a tree. Can you please provide some guidance on this part? Or am I totally missing something and there is an endpoint/contract I can call to get the proofs?
Thank you.
