Rarimo is an interoperability protocol making assets, identities, and dApps multi-chain. One of the key features distinguishing them from all other interoperability bridges is their focus on decentralized identities and social. By making metadata retrievable, and by replicating credentials, Rarimo enables Soulbound Tokens (SBTs), NFTs, and other components of on-chain identity to seamlessly travel across chains. Accordingly, we believe that they are well-positioned to bring interoperability to decentralized social layers.

Rarimo has also pioneered new use cases for cross-chain digital assets transfers, such as NFT checkouts, which allow users to buy NFTs using any cryptocurrency, regardless of the blockchain it’s held on. They eliminate excess transaction fees and time-consuming manual steps from an endless range of use cases, and instead offer users single-click, single-fee solutions. Pantera recently led a $10M round in Rarify Labs, one of Rarimo’s service providers, along with Protocol Labs, Circle, Eniac, Slow, Hyper, and Greycroft.

Problem space

As more layer 1s and 2s continue to enter the space, fragmentation is becoming an increasingly urgent issue. Users need to be able to access their assets and identities from across different ecosystems.

While in the case of digital assets, pre-existing solutions do exist, they often offer a poor user experience or have limited functionality. Users are generally required to pay multiple transaction fees, provide multiple signatures, execute multiple manual steps, and in some cases, shoulder a vulnerability to hacks. When solutions do offer an improved user experience it generally comes at the cost of providing universal support. Typically, they support only a narrow range of use cases and are often only focused exclusively on the transfer of ERC-20 tokens. This infrastructural bias makes it extremely challenging to expand to other ecosystems.

Meanwhile, users of decentralized social layers are currently unable to transfer their identity artifacts from one blockchain to another let alone in a seamless, cost-efficient manner.

Architecture and how Rarimo works

Their highly composable multi-layer architecture is what allows Rarimo to support such an expansive range of use cases. It consists of three components: the Base Layer which operates as a generalized messaging protocol and includes an independent and decentralized blockchain; the Cross-chain Layer which includes bridging and oracle services; and the Application Layer which leverages the two underlying layers to provide support for specific projects.

The protocol was designed to provide the low transfer costs of centralized solutions, but the security of decentralized ones. Rarimo creates proofs using a Threshold Signature Scheme that reduces network costs while also supporting a large number of independent validators. On top of this, Rarimo bundles transactions. This allows multiple flows to be executed at once, and therefore saves users from having to pay multiple transaction fees.

As well as improving the experience for users, Rarimo’s design makes development faster and easier for builders whose dApps leverage multi-chain liquidity and access. The Application Layer means developers can effortlessly expand existing dApps from one chain to many without having to build notable amounts of custom, use-case specific logic.

Currently, Rarimo supports Ethereum, Solana, Binance, Near, Avalanche, and Polygon. Rarimo’s testnet is currently accepting developer applications.

Rarimo x Circle

Most recently, Rarimo partnered with Circle, a Pantera portfolio company, to integrate Circle’s Cross-Chain Transfer Protocol (CCTP). This allows USDC to flow natively across chains for NFT payments.

Right now, users who hold USDC on one chain and want to buy NFTs listed on another face an extremely complex process. They are forced to manually exchange their tokens on a DEX, accruing multiple transaction fees along the way. With the Rarimo x CCTP integration however, they will be able to make cross-chain NFT purchases with USDC with only a single click, and paying only a single transaction fee.

Developers can also utilize the Rarimo-CCTP integration to enable paying in USDC while minting NFTs on different chains.

Rarimo Use Cases

Rarimo’s additional interoperability use cases include:

●  Access: cross-chain proof of identity including SBTs, multi-chain DAO voting and governance, and multi-channel state replication

●  Liquidity: cross-chain NFT purchases, proof of ownership / reputation for lending, NFT fractionalization, optimized NFT pooling / staking, and bulk transferring NFTs between chains

●  Compatibility: scaling assets multi-chain for metaverses, cross-chain NFT drops, brand asset migration by end users, and layer 1 to layer 2 (or vice versa) asset swaps

Team

Rarimo is maintained by the decentralized Rarimo Foundation. Service provider, Rarify Labs, was founded by Lasha Antadze, Revaz Tsivtsivadze, and Vlad Dubinin in late 2021. Revaz has previous experience in APIs and fintech products including Shutterstock and Mastercard. Lasha and Vlad are the previous co-founders of Shelf Network, a platform for cross-border decentralized auctions, and Vlad is also the co-founder of Distributed Lab, one of the largest Blockchain research and development centers.

We believe that Rarimo is well-positioned to solve the imminent issue of fragmentation to become a leader in the interoperability space. They are set apart by their modular, multi-layer architecture which enables hyper-secure and user-friendly multi-chain transactions. We at Pantera are thrilled to back Rarify Labs as they continue to develop solutions for the secure transfer of data, identity, and digital assets across web3.
