Ripple’s EVM sidechain represents a potential game-changer for the company’s payment infrastructure, allowing Ripple to tap into Ethereum’s deep liquidity pools while maintaining the fast, efficient, and low-cost transactions offered by the XRP Ledger (XRPL). The integration of Cosmos SDK in the EVM sidechain adds further flexibility and cross-chain capabilities, allowing for more advanced use cases, such as decentralized finance (DeFi) applications, all while bridging between the XRPL and Ethereum ecosystems.
Leveraging Ethereum’s Liquidity for Payment Settlement
One of the key reasons Ripple may want to incorporate an EVM-compatible sidechain is to take advantage of Ethereum’s superior liquidity. The Ethereum network is home to a vast and diverse array of liquidity providers, decentralized exchanges (DEXs), and financial protocols that Ripple can utilize for large-scale payments. This is especially beneficial in cross-border payments, where multi-currency liquidity is essential for efficient market-making.
Why Ethereum for Liquidity?
• Liquidity Depth: Ethereum’s established DeFi ecosystem provides Ripple with access to deep liquidity pools across various assets, from major cryptocurrencies to stablecoins and synthetic assets. Ethereum-based DEXs like Uniswap and Curve offer liquidity for both major currencies and lesser-known tokens.
• Complex Financial Products: Ethereum allows Ripple to tap into more complex financial tools and services, such as decentralized lending, options trading, and derivatives, which are not currently feasible on XRPL.
Through the EVM sidechain, Ripple can execute smart contracts and interact with Ethereum’s liquidity while managing cross-chain payments. This strategy provides the flexibility to use Ethereum’s DeFi protocols where necessary while keeping payment routing and ledger functionalities on the XRPL.
XRPL’s Payment Routing: Essential with Bridging Technology
Ripple can still route payments through the XRP Ledger while benefiting from the liquidity on Ethereum, thanks to bridging technology. The key here is to allow seamless asset transfer between XRPL and Ethereum, facilitated by the Axelar network or similar bridging solutions. This enables transactions to be initiated on XRPL, processed through smart contracts on the EVM sidechain, and ultimately settled on either XRPL or Ethereum depending on liquidity and transaction type.
• How Bridges Work: Bridges connect XRPL with the EVM sidechain and Ethereum, allowing assets like XRP or RLUSD (Ripple’s stablecoin) to flow across chains. Tools like Axelar GMP (General Message Passing) handle the communication between XRPL and the EVM sidechain.
• Smart Contract Support: The EVM sidechain allows Ripple to offer programmability for payments using Ethereum-compatible smart contracts while keeping the core XRP functions — like payments, DEX, and escrow — intact.
Why Light Smart Contracts on XRPL?
Ripple may also want to incorporate light smart contract capabilities into XRPL itself to manage simple logic and automation without relying heavily on external chains. These could be used to facilitate cross-chain transactions, bridges, or automated processes that ensure transaction efficiency while still routing most payments through XRPL.
How the EVM Sidechain Uses the Cosmos SDK
The Cosmos SDK is a modular framework that simplifies the process of building custom blockchain applications. Ripple’s EVM sidechain is built using this framework to offer flexibility and scalability. Here’s how the Cosmos SDK contributes to the overall structure:
1. Modular Design: The Cosmos SDK allows developers to easily integrate modules, making it easier to add new features and adapt the blockchain to specific use cases. In the case of Ripple’s EVM sidechain, modules for EVM compatibility, governance, and staking are all essential parts of the sidechain’s functionality.
2. Interoperability: One of Cosmos SDK’s standout features is IBC (Inter-Blockchain Communication), which provides a standardized way to connect blockchains. This is vital for Ripple’s sidechain, as it allows seamless interaction between XRPL, the EVM sidechain, and Ethereum.
3. Cross-Chain Capabilities: The Cosmos SDK enables easy integration of cross-chain messaging protocols, like Axelar, which Ripple uses to facilitate bridging between XRPL and Ethereum. This ensures smooth asset transfers and communication between the two networks while still leveraging the strengths of both ecosystems.
By utilizing the Cosmos SDK, Ripple’s sidechain can maintain compatibility with Ethereum’s EVM, allowing for smart contract functionality and DeFi operations, while still benefiting from the security and low fees offered by XRPL. This is particularly important for complex payment structures that require both fast settlement and access to Ethereum’s liquidity.
The EVM Sidechain’s General Build
Ripple’s EVM sidechain is a parallel blockchain to the XRP Ledger, designed to be EVM-compatible and run Ethereum-based smart contracts. This sidechain bridges the gap between Ripple’s fast and efficient payments system and Ethereum’s programmability. Below are some key components of the sidechain’s build:
1. EVM Compatibility: The EVM sidechain supports the same Ethereum Virtual Machine (EVM) that powers Ethereum’s smart contracts, allowing developers to deploy Solidity contracts on the Ripple sidechain.
2. Cross-Chain Bridges: The sidechain is designed to interact with XRPL and Ethereum through bridges like Axelar, allowing assets to flow seamlessly across these chains. This setup gives Ripple access to Ethereum’s DeFi ecosystem, while still keeping payment functions on the XRPL.
3. Governance and Security: The governance of the bridge between the XRPL and the EVM sidechain uses Gnosis Safe, a multisig wallet solution to secure transactions across chains.
4. Transaction Flow: Payments can be initiated on the XRPL, routed through the EVM sidechain to tap into Ethereum liquidity, and then settled based on transaction needs. For instance, transactions that require more liquidity may settle on Ethereum, while smaller transactions may stay within XRPL for faster finality.
Conclusion: A Hybrid Payment System for the Future
Ripple’s EVM sidechain represents a hybrid approach that can handle a variety of payment needs. By integrating Ethereum liquidity with the speed and efficiency of XRPL, Ripple can offer a more flexible, scalable, and efficient payment infrastructure. The use of the Cosmos SDK makes the sidechain modular and adaptable, while bridges like Axelar ensure seamless asset movement between XRPL and Ethereum.
This hybrid model could significantly improve Ripple’s ability to offer global payment services while also tapping into the DeFi ecosystem on Ethereum, unlocking new opportunities for liquidity, smart contracts, and decentralized applications.
