Concordium support RWA

NHS · October 17, 2023, 9:12am

In a recent Q4 roadmap update, it was mentioned that Concordium will soon support RWA tokenization. I was wondering if there is any documentation ready, especially regarding how the asset is defined on-chain - what kind of data can be added to ensure the definition of the assets can be linked to the exact real-world item.

To support RWA tokenization, we will add one more tool to our product line in addition to Agora and Agora Impact. We are trying to address different aspects of the tooling to help use cases, empower them, and save their development time. Currently, there is no documentation ready about this tool, but what you can look into is the logic of Agora Impact. Agora Impact is actually a real-world asset tokenization platform, specifically targeting carbon credits. It allows people to tokenize these real-world carbon credits in the form of an NFT, based on provided inputs and a report generated by accredited authorities lets call them verifiers. By default, these tokens are unverified and there are some limitations on what an unverified token can be used for like trading. The verifiers are responsible for going and checking the report and other info provided when minting, which is the token’s metadata. If everything is alright, and the info is accurate then they change the token’s state from unverified to verified and then the token can be traded/fractionalized or retired. By doing that, we are bringing verification on-chain and making not only the asset owners but the verifiers accountable. I don’t know if this is too long or answers your question, but you can always book a meeting to discuss the options that are specifically applicable to your use case.

Thank you for the detailed explanation. We link real-world physical products—like rare collectibles, wines, medicines, etc.—using encrypted tags embedded into the physical products. The tag unique ID that is linked to NFTs on-chain with ownership to the account owning the real-world product. This way we can identify the exact product linked to the NFT. We use the NFT metadata to describe the product (this can include serial numbers, colors etc). This works fine as-is, but maybe we could benefit from using the standard RWA tools.
