NFTs Development Cases in Cosmos Ecosystem

Table of Contents

NFTs has led a wave of trends in the blockchain community recently. But what is the current state of NFTs development in the Cosmos Network ecosystem? Let’s check it out!

NFT Module on Cosmos SDK

Application-Specific NFTs on Cosmos

Cosmos had committed to developing the NFT module since 2019. After merging their development results into the master branch in late August (refer to this PR), they published the above article in early September. It gives a short introduction to NFT and explains the functionalities of several basic structs and interfaces in the NFT module.

If you’d like to jump straight to the good stuff check out the spec here , the code here and a sample app using the module here.

Readers who try to dig deeper into the implementation details might have noticed the links to spec and code in the introduction section were broken. It’s probably due to that developers had moved the whole NFT module to the modules/incubator/nft folder in October (refer to this PR).

However, the Cosmos development team had stopped updating the NFT module for an unknown reason later on. The GitHub page shows that the last update was in June 2016. The NFT module stays unfinished.

(2021/05/19 Update: The discussion for implementing a generic NFT module has returned and is now ongoing on GitHub.)

InterNFT Working Group


The InterNFT Working Group commits to initiating Interchain standards to make NFTs interoperable across blockchain networks. They proactively participate in the 🧰-did-nft-and-metadata channel of the Cosmos Discord community. The period of the lastest phase is from September 2020 to March 2021. The working group holds an online meeting in a weekly cycle. The meeting records are stored on YouTube. Documents can be found on the official site and GitHub. The working results are mostly classified into standards and protocols.

This thread talks about several NFT standards and implemented cases (including two cases mentioned above), compares their pros and cons and suggests a simple proposal and basic requirements.

The implement details of the IRISnet NFT module that Uptick applied can refer to the repo irisnet/irismod. It’s basically derived from the NFT module of Cosmos SDK, but many amendments have been made since the first PR, and the repo is kept up-to-date.
