Cross-Chain Liquidity Explained | Rubic

Tl;DR

  • Fragmented liquidity across blockchains limits DeFi’s potential.
  • Cross-chain liquidity allows users to seamlessly swap assets between blockchains.
  • It can increase user adoption, create deeper market liquidity, and amplify innovation.
  • However, it is crucial to consider security risks, transaction fees, and user complexity in cross-chain swaps.
  • Cross-chain liquidity simplifies swaps and eliminates reliance on centralized exchanges.

The volatility in the crypto market is what makes it both risky and profitable at the same time. However, most markets struggle to unleash their full potential due to a lack of liquidity. A lack of liquidity primarily exists in a decentralized environment where different networks work in silos and the liquidity is fragmented. Centralized exchanges solve this problem to some extent by leveraging market makers, but this comes with the risks of losing control over your own funds and trusting a central authority leading to a concentration of power, the antithesis of blockchain decentralized ledger technology. Thus, having cross-chain liquidity enables users to transfer their assets across the blockchain network without the need for any central entity.

What Is Cross-Chain?

Cross-chain refers to tech that enables the transfer of assets such as cryptocurrencies, NFTs, and information across different blockchain networks. As we are moving to a more developed Web3 ecosystem, it is becoming increasingly important for us to establish an interoperable system that allows users to navigate through different chains.

What Is Cross-Chain Liquidity?

Liquidity in a decentralized financial market refers to the availability of capital for completing a trade. When there are enough buyers and sellers, a market becomes liquid as trades can be executed quickly at each price level. However, in crypto, the availability of multiple networks means that liquidity providers, buyers, and sellers distribute their liquidity across blockchains and exchanges – also known as fragmented liquidity.

Cross-chain liquidity builds upon the foundation of cross-chain technology by addressing the issue of fragmented liquidity in DeFi. It essentially unlocks the ability to aggregate liquidity pools creating a more efficient and interconnected DeFi ecosystem. With cross-chain liquidity, users can swap tokens seamlessly, access a wider range of DeFi applications, and enhance capital efficiency. By combining liquidity pools, cross-chain solutions ensure tighter spreads and better pricing for users.

How Is Liquidity Aggregated Across Chains?

Liquidity aggregation across chains involves pooling liquidity from multiple decentralized exchanges (DEXs), liquidity pools, and bridges on different blockchains to offer the best rates, lowest slippage, and optimal trading conditions for users. Here’s how the process generally works:

1. Cross-Chain Aggregators

Cross-chain liquidity aggregators, like Rubic, act as intermediaries that connect multiple DEXs and liquidity providers from different blockchains. This allows users to seamlessly swap tokens across different blockchains without manually navigating through separate exchanges. The aggregator pulls liquidity from several sources, ensuring users always get the most favorable rates.

2. Routing Algorithms

The heart of liquidity aggregation is the routing algorithm. It works by checking liquidity pools across different chains and DEXs to identify the best available route for a trade. This means the algorithm compares factors like exchange rates, fees, and slippage across various platforms, ensuring the most efficient trade. For example, Rubic’s algorithm sources liquidity from over 90 DEXs and bridges, scanning for the optimal route in real-time.

3. Cross-Chain Bridges

To facilitate liquidity movement between chains, cross-chain bridges are used. Bridges enable tokens or liquidity to be transferred between different blockchains, allowing users to swap assets across various networks. When liquidity is needed on a different blockchain, the cross-chain aggregator relies on bridges to move the assets.

4. Liquidity Sources

The aggregation system taps into different types of liquidity sources, including:

  • DEXs: Decentralized exchanges that provide liquidity for token swaps.
  • AMMs (Automated Market Makers): Platforms like Uniswap and PancakeSwap, which use liquidity pools instead of order books to facilitate trades.
  • Bridges: Tools like Symbiosis, Wormhole, or any native cross-chain bridge that transfers assets between different blockchains.
  • Liquidity Providers: Users or protocols that supply liquidity in exchange for transaction fees or yield.
  • Liquid staking: A DeFi innovation that allows users to stake their tokens in a proof-of-stake (PoS) blockchain network while still maintaining liquidity over their staked assets. Liquid staking solves this problem by giving users a tokenized representation of their staked assets, which can be used across other DeFi applications.

The Importance of Cross-Chain Liquidity in DeFi

The potential benefits of cross-chain liquidity for DeFi are vast. Here are some key advantages:

  • Increased User Adoption: By removing barriers to entry and allowing users to leverage their assets across various DeFi applications, cross-chain liquidity can significantly boost DeFi adoption.
  • Deeper Market Liquidity: Aggregating cross-chain liquidity pool create a deeper and more efficient market providing better price discovery for traders to trade and make money. Ultimately, leading to tighter spreads and better overall user experience.
  • Encouraging Innovation: With the ability to freely move assets and interact with different DeFi protocols, cross-chain liquidity can encourage developers and stakeholders to innovate and develop more advanced Cross-Chain DeFi applications helping the economy prosper.

All these advantages will encourage more people to join the crypto revolution and participate in the Web3 ecosystem. But that’s not to say cross-chain liquidity doesn’t have its current setbacks.

Challenges of Maintaining Cross-Chain Liquidity

While cross-chain liquidity offers significant advantages, it’s not without its challenges. Here are some key considerations:

  • Security Risks: Cross-chain bridges, which facilitate communication between blockchains, can be complex and introduce potential security vulnerabilities. Thorough audits and secure implementation are crucial.
  • Transaction Fees: Moving assets across chains can involve additional fees, which can impact user experience and overall transaction costs.
  • Complexity: Understanding and navigating the various cross-chain liquidity solutions can be challenging for new users, requiring a user-friendly interface and educational resources.

Unlocking Seamless Swaps: How Cross-Chain Liquidity Works

Let’s illustrate it with a practical example of how cross-chain liquidity facilitates a seamless swap:

Imagine you hold Ethereum (ETH) on the Ethereum blockchain and want to swap it for USD Coin (USDC) on the Solana blockchain. Outside of DeFi, this would involve:

  1. Transferring your ETH to a centralized exchange that supports both ETH and USDC.
  2. Selling your ETH for USDC on the exchange.
  3. Withdrawing your USDC from the exchange to a Solana wallet on the Solana network, OR 
  4. Bridging your USDC from the ETH network to the Solana network

This process can be time-consuming, involve additional fees, and expose you to counterparty risk:

With cross-chain liquidity, the process is vastly simplified:

  1. You connect your Ethereum wallet to a cross-chain swap aggregator, a platform that searches for the best rates across various cross-chain liquidity providers.
  2. The aggregator identifies the most efficient route for your swap, considering factors like liquidity availability and fees on different chains.
  3. The swap aggregator interacts with a cross-chain liquidity protocol that utilizes mechanisms like atomic swaps, locked vaults, or cross-chain bridges to facilitate the exchange.
  4. Your ETH is securely transferred on the Ethereum blockchain, and the corresponding amount of USDC is made available on the Solana blockchain, all handled by the cross-chain liquidity protocol.

This streamlined process eliminates the need for centralized exchanges and allows you to swap tokens directly between blockchains with greater efficiency and potentially lower fees.
