Groundbreaking NFT System on Kusama Brings Advanced NFT Capabilities to Moonriver

Singapore – November 12, 2021 – Moonbeam, the Ethereum-compatible smart contract platform on Polkadot, announced the integration of Moonriver with RMRK, an extensible NFT system on Kusama. As part of this integration, the teams will collaborate to develop Solidity standards for RMRK-based Kusama assets. This will allow Moonriver and other EVM chains to work with RMRK NFT infrastructure, providing advanced features for NFT developers, creators, and collectors across the Kusama ecosystem.

Moonriver is the first EVM to host RMRK-based NFTs, bringing RMRK’s advanced NFT functionality to the broader MOVR ecosystem. Moonriver is a natural expansion point since it has dozens of NFT projects already deployed, with many more on the way. Moonriver natively supports ERC-721 and ERC-1155 standard NFTs positioning it as the top destination for Ethereum-compatible NFTS with the largest number of deployed protocols and users.

“Moonriver is what Ethereum has long wanted to be – a proof-of-stake EVM network with on-chain governance, secured by a large set of stakers rivaling the economic security of Ethereum itself,” says Bruno Škvorc, founder of RMRK. “With Moonriver’s growing popularity and RMRK’s explosive growth, it only makes sense for us to take RMRK to the next level and augment our versatile NFT legos even further in an EVM environment as receptive as Moonriver’s.”

Through this integration, Moonriver developers will be able to leverage RMRK’s building blocks to construct advanced NFTs without having to write smart contract code. Unlike traditional ERC721 NFTs, RMRK NFTs can evolve over time, own or equip other NFTs, and change their output based on emotes and other creator specified rules. They are also inherently multi-chain which is a natural fit for Moonriver, and they can be governed as DAOs through derived fungible tokens.

Users will also be able to establish an item economy for their project, as well as cross-project compatibility. RMRK assets will be able to move freely on Moonriver marketplaces in the future. The very first cross-project integrations are already planned, and so the popular NFT collection MoonSama on the Moonriver network will be able to equip and visualize certain NFTs that originated on the Kusama blockchain as part of another project entirely.

“Moonriver brings Ethereum tools and standards to Kusama, but this is not a one-way street,” says Derek Yoo, Founder of Moonbeam. “The goal is also to bring Kusama features and standards into the Moonriver EVM environment. RMRK is a great example of a Kusama-native project and standard seeing significant traction, which can enhance and extend the Ethereum environment on Moonbeam. We are excited to support the RMRK team to bring advanced Kusama-native NFT functionality to Moonriver-based developers.”

About the Moonbeam Network

Moonbeam is an Ethereum-compatible smart contract platform on the Polkadot network that makes it easy to build natively interoperable applications. This Ethereum compatibility allows developers to deploy existing Solidity smart contracts and DApp frontends to Moonbeam with minimal changes. As a parachain on the Polkadot network, Moonbeam will benefit from the shared security of the Polkadot relay chain and integrations with other chains that are connected to Polkadot. Currently, in active development by PureStake, Moonbeam is expected to reach MainNet by Q4 of 2021. Learn more:

About RMRK

The RMRK protocol is a system of NFT Legos which allows developers and designers to build composable, equippable, multi-resource NFTs which are multi-chain by default by virtue of being launched on Kusama, the center of a multi-chain universe. The NFTs can visually change based on other NFTs they own, but these NFTs are also eternally liquid and forward-compatible in that they can be made equippable by unrelated future projects that aren’t even planned yet.
With RMRK tokens in the hands of the community, the protocol is to NFTs what Ethereum was to Bitcoin – a paradigm shift that takes a single thing’s single use-case and dramatically augments it.
