Difference seaport js Vs Open Sea Js about seaport-js

[nfts4f4fff]

hey. Thats a good question. Opensea interacts with a different contract then seaport. When i list a nft it interacts with a totally different contract then seaport

[dineshtiwari69]

So Seaport is a NFT Marketplace Contract which means anyone can use seaport to create their own marketplace .

Opensea uses seaport for it's marketplace.
Every marketplace has a Conduit Contract responsible for the transfers.
Opensea has it's own conduit .

Opensea-JS helps index your signature orders so that it gets displayed in Opensea . Thus it requires Opensea API's.

If you try to sell an order through seaport-js , opensea wont know anything about it .

If you are dedicated to listing in Opensea , then use opensea-js .

I hope that's clear . This is what i know so far from going through docs over and over again.

(Correct Me If I am Wrong)

And i am right. Opensea.js is a JavaScript library for crypto-native ecommerce: buying, selling, and bidding on any cryptogood. With OpenSea.js, you can easily build your own native marketplace for your non-fungible tokens, or NFTs. These can be ERC-721 or ERC-1155 (semi-fungible) items. You don't have to deploy your own smart contracts or backend orderbooks. How that seaport.js help building your own marketplace ? It doesnt. Its mainly for interacting with opensea. It uses the opensea order flow.

I wanna list a nft on opensea using seaport. Opensea doesnt allow you to list multiple nfts in one signature. Thats why i and other people are using seaport.

hum ... I went through the doc several times, but I don't get how it works and what we shoud use to interact with opensea ? do u have any clue where I could find further explanation?

[sunwrobert]

Use opensea-js. The explanation from @dineshtiwari69 should suffice

[FloUz-ai]

Yeah all good I went through the doc again, and read some discussion about seaport. Then I understood the example, and that's perfect, I think I've got the basics.

That's just strange that opensea does not see the listing when they are validate ...
