Uniquery 1.0.1

Everything in this repo has been coded from scratch during the Polkadot Global Series hackathon (3 – 23 July 2023).

This project is production ready.

Uniquery.Net

Easy to use tool for querying indexed NFT data.

This is a c# implementation of Uniquery with many improvements on top.

Improvements

• Overall structure has been improved:
  • confusing method getClient("name") has been replaced with static functions.
  • All types have been converted to native c# classes
• Uniquery.Universal - very cozy way to query data from multiple endpoints at the same time.
• Inclusion of new Networks/NftStandards, that are missing in the original uniquery: Acala, Astar, Shiden, Unique, Quartz, Opal
• More flexible parameters

Installation

Nuget package: https://www.nuget.org/packages/Uniquery/

dotnet add package Uniquery

Supported Networks/NftStandards

• Rmrk
• RmrkV2
• Basilisk
• Glmr
• Movr
• Unique
• Quartz
• Opal
• Acala (OnFinality BETA)
• Astar (OnFinality BETA)
• Shiden (OnFinality BETA)

Motivation

Originally, I just wanted query NFT data to display them in PlutoWallet. Afterwards, I received request from Kodadot to make a full c# implementation, hence, here it is.

This tool will be useful to many people and will significantly simplify the querying of NFT data.

Without Uniquery you would have to write something like this:

query itemListByCollectionIdList {
 nft: nftEntities(where: { collection: { id_eq: "7EA1DCF47E98A25067-CAVE" }}) {
 id
 metadata
 currentOwner
 issuer
 }
}

With Uniquery you can write this:

string id = "7EA1DCF47E98A25067-CAVE";
var nfts = await Uniquery.Rmrk.NftListByCollectionId(id);

Use of Uniquery.Universal

One of the major improvements over the original Kodadot/Uniquery js package is the inclusion of Uniquery.Universal

Without Uniquery.Universal you would have to write something like this:

string address = "5HGuhwGJZC5zvWQm1kGpobJxwAv6bUtKyLGjKL7m2YaJtmDQ";
List<Nft> nfts = new List<Nft>();
nfts.AddRange(await Rmrk.NftListByOwner(address, limit, offset, orderBy, forSale, eventsLimit));
nfts.AddRange(await RmrkV2.NftListByOwner(address, limit, offset, orderBy, forSale, eventsLimit));
nfts.AddRange(await Unique.NftListByOwner(address, limit, offset));
nfts.AddRange(await Quartz.NftListByOwner(address, limit, offset));
nfts.AddRange(await Opal.NftListByOwner(address, limit, offset));
nfts.AddRange(await Basilisk.NftListByOwner(address, limit, offset, orderBy, forSale, eventsLimit));
nfts.AddRange(await Glmr.NftListByOwner(address, limit, offset, orderBy, forSale, eventsLimit));
nfts.AddRange(await Movr.NftListByOwner(address, limit, offset, orderBy, forSale, eventsLimit));
nfts.AddRange(await Acala.NftListByOwner(address, limit, offset));
nfts.AddRange(await Astar.NftListByOwner(address, limit, offset));
nfts.AddRange(await Shiden.NftListByOwner(address, limit, offset));

With Uniquery.Universal you can write this:

string address = "5HGuhwGJZC5zvWQm1kGpobJxwAv6bUtKyLGjKL7m2YaJtmDQ";
List<Nft> nfts = Uniquery.Universal.NftListByOwner(address);
