Rubic For the Interoperable Future of Web3: Cross-Chain Swaps in One Click

Cryptocurrency Market Needs Interoperability

Every crypto project resides on a certain blockchain which serves different purposes. At this moment there are about 131 chains operating and over 19,000 tokens in circulation at this moment (Rubic supports 15,000 tokens!).

How to Swap Across Blockchains?

As blockchain started moving to Web3, where chains can interact with one another, the market has offered multiple cross-chain models. All in all, the cross-chain space can be divided into bridges, aggregators, and cross-chain messaging protocols.


A bridge is an application that enables transactions between two networks, be they layer 1, layer 2, or even an off-chain service. Simply put, bridges allow users to transfer their assets from one network to another. For example, USDC holders on Ethereum may wish to transfer their USDC from Ethereum to Avalanche via the bridge application.

  • low security: 2021 year experienced more than 1.2B funds stolen through bridges in hacker attacks;
  • the excessive amount of time spent on a swap: 15 minutes and 20 clicks on average.

Cross-Chain Messaging Protocols

Those are designed to move a wider range of information types between chains — additionally to exporting tokens, they can send contract calls, proofs, and states. Among the most famous ones are the Inter-Blockchain Communication (IBC) Protocol, Axelar, Nomad, LayerZero, and Chainlink CCIP. Also, Celer has its Inter-chain Message Framework.
Cross-chain messaging protocols vary in terms of functionality and operation. For example, IBC is the standard for chain interoperability in the Cosmos ecosystem. The chains adopt and use the IBC messaging standard while light clients in both networks and relayers (those who directly move information) take responsibility for cross-chain interaction. IBC is not suitable for all chains — it’s expensive and inconvenient for chains outside of the Cosmos ecosystem.

Aggregators of Bridges & DEXs

This has become another step in augmenting interoperability in the blockchain world. In a nutshell, aggregators of bridges and DEXs pack the swap-bridge-swap into a user-friendly interface and better user experience (as it’s also possible to change the token which is being moved across chains).

Rubic — the Amazon of Crypto

Rubic has been one of the first players in the cross-chain market, and also one of the first aggregators. Rubic goes by the name of “Aggregator of Aggregators” or the “Amazon of Crypto” since it aggregates 13 blockchains and 70+ DEXs and bridges (which is the biggest number amongst aggregators so far).

The Biggest Number of Tokens and DEXs

Rubic has the most significant amount of tokens for swapping amongst all bridges and aggregators — 15,000+! Just imagine — there are in total 19,000+ tokens circulating in the crypto market, taking into account that some of them are not active. On Rubic, with 60+ aggregated DEXs, you almost have no limits in choosing the assets to swap.

Best UX/UI — Swap in One Click

Сross-chain swaps have a complicated route: swap — bridge/DEX — swap. Rubic is a time saver allowing users to swap tokens in just 1 click and confirm the transaction from their wallet 1 time. And unlike bridges, you can swap across chains, and also change the token which is being moved across chains.

Best Rates & Timings

On Rubic, the average transaction time takes no more than 3 minutes. The algorithm used at Rubic manages transactions as needed, to save on gas and fees as much as possible, thus finding the best deal on the market for cross-chain and on-chain swaps.

Security & Guaranteed Liquidity

Thanks to the aggregation of DEXs, providers, and bridges, users will always have sufficient liquidity when making a swap. If a bridge or a provider gets hacked or runs out of liquidity, Rubic redirects users to another bridge or a provider. Rubic has an auto-refund feature, and its technical support is ready to assist 24/7.

Low Swap Fees

No matter what amount of crypto you swap, for any transaction you always pay just a $1 fee which is charged in the source network native coin. So you just pay a $1 fee without the need to count your swapping expenditures! If you hold more than 5k $RBC tokens, you will get a regular weekly refund for the fees you’ve paid for your swaps — they will be absolutely free of any fees!

Profit Maker — Rubic Staker

Staking on Rubic proposes another opportunity for Rubic token holders to make a profit on their investments. By staking RBC, one can earn up to 58% APR, which is one of the highest APR in the market and make their “cubes” work.

Battletested By Crypto Market

Since the start of our SDK and widget, after just 8 months, Rubic already services 80+ crypto projects, helping them to become interoperable omnichain ecosystems. Integration (for its simplest version) takes just 10–30 minutes and enables cross-chain swaps of 15,000+ on- and across 13 blockchains. Newly-launched tokens are automatically listed via Rubic’s API, as soon as they are available on our listed DEXs.

NFTs at Your Fingertips

A new era has come! Purchasing NFTs in 1 transaction with various tokens and from multiple blockchains has become possible. By integrating Rubic NFT Widget, NFT projects enable buyers to acquire NFTs with more than 15,000 tokens and across 13 blockchains integrated into Rubic.

Why Rubic is Better Than Other Aggregators

The cross-chain world has been witnessing a spate of newly- launched omnichain projects — each of them with a “unique cross-chain model”. Besides Rubic, there are other aggregators like Via.Exchange, Rango, O3Swap, and LI.FI.

  • Rubic stays ahead of the pack considering the number of tokens supported for swaps: 15,000+ tokens (out of 19,000 in the market total supply).
  • Automated swaps in 1 click: No manual steps are needed to make a swap on Rubic — you make one click and the swap is done!
  • 60+ aggregated DEXs: Rubic aggregates the biggest number of DEXs participating in cross-chain swaps — this gives better rates and swap times.
  • 16 integrated bridges: Rubic guarantees liquidity for any swap due to 16 bridges integrated into the app; this number is constantly growing.
  • Widget: Any crypto project can integrate Rubic widget in just 5 minutes and expand to the cross-chain Web3.
  • Timing: Depending on the amount for a swap, no more than 3 minutes is needed to make a cross- or on-chain swap on Rubic which cannot be said about Rubic’s competitors. Are you ready to wait for your swap to be done in 13 or 8 minutes like on other websites? If not, go for Rubic — you will spend no extra minute — be it a cross-chain or on-chain swap.

How to Choose the Best Cross-Chain Solution?

While the innovations around cross-chain technology are gaining momentum, only a few projects have launched practical solutions. To choose the most cost-efficient and convenient swapping service, one should pay attention to several factors:

  1. Number of Tokens


Interoperability and Web3 are just around the corner. Soon, cross-chain solutions will play a pivotal role in the further development of blockchain technology since it will largely influence the adoption of blockchain and cryptocurrency.
