Growing DeFi with Layer-3 Solutions: How Aggregated Roll-ups Can Help

Imagine you are in a busy market, and all the sellers are willing to accept only certain payment types. A customer holding fiat in his wallet experiences discomfort as he cannot easily swap or buy anything. This is similar to the existing situation with liquidity fragmentation in the Blockchain environment. Assets are fragmented over numerous chains, and they are barely able to communicate, thus resulting in approximately no percentage of the Decentralised Finance (DeFi) dream. Now, that is where leyer-3 solutions come in handy.

Liquidity Fragmentation in DeFi

With little consideration of liquidity, cross-chain value transfer becomes more challenging. Generally, this is becomes a success through expensive and complicated bridging process. Users are have to dela with numerous of swaps and transfers that are expensive and time-consuming, thus providing a bitter taste to the whole process. These inefficiencies injure the development of decentralized applications (DApps) and Decentralized Finance (DeFi) platforms and disappoint the user.

Layer-3 solutions will solve this problem by bringing assets and liquidity from various Blockchain ecosystems, hence easier to trades. This includes complex processes and applications with intelligent contracts to combine and engage assets on distinct Blockchains. The net effect is that the liquidity is higher, and user experience is associated with better-defined and smoother transactions.

Leveraging Roll-ups for Scalability

Basically, roll-ups scaling solutions help improve the efficiency of Blockchain systems. They act through several transactions integrated into a batch that is solved off-chain and recorded in the main Blockchain. This considerably lowers the What cost and enhances the throughput.

There are two main types of roll-ups:

• Zero-knowledge roll-ups (ZK-rollups): These use cryptographic proofs to validate transactions.
• Optimistic roll-ups (OP-rollups): These assume transactions are valid by default. It relies on fraud proofs to detect and correct invalid transactions post-submission.

ZK-rollups or OP-rollups are Layer-2 (L2) solutions for scalability, and although these solutions help disperse liquidity among multiple chains, they hinder user experience.

One existing solution that relies on the above-mentioned technologies to address liquidity fragmentation is zkLink. This is an aggregated roll-up developer based on ZK which offers two main products, namely zkLink Nova and zkLink X.

zkLink Nova

zkLink Nova is a full roll-up aggregator based on zkEVM, a zero-knowledge Ethereum Virtual Machine. Cross-chain roll-ups integrate several asset roll-ups into one roll-up, improving efficiency and compatibility. Consequently, the zkLink Nova is an all-in-one solution that allows users to trade or interact with the ZK and OP ecosystems in a single pool.

zkLink X

zkLink X is a highly scalable scaling solution built specifically for DApps. The current system allows the roll-up of various chains into an app-specific chain with quick deployment and compatibility on other chains.

Based on the API and SDK principles, the development of zkLink X is relatively easy. The scaling engine lets DApps pool funds and introduce sophisticated financial instruments such as multichain asset lending.

Streamlining Development with Layer-3 Solutions

It offers developers easy integration and a single place to interact with the chain and the developed abstraction. Teams can use zkLink Nova to get the combined asset pool from many chains so they can build more adequately capitalised DeFi products with deeper asset pools.

Using zkLink X, developers can integrate the receiving of deposits from other supported linkages such as BNB Chain, Solana and Arbitrum for DApps. Ostensibly, DeFi can utilize zkLink’s structure based on zk-SNARKS, which facilitates settling at various Blockchains and boosts security. Grand support from zkSync in terms of ZK stack enables developers to retrofit EVM applications into zkEVM applications with zero-knowledge security.

Solving Interoperability with Stack-Agnostic Roll-ups

zkLink roll-ups eliminate compatibility challenges that may arise within different stacks, including the Polygon CDK, the OP Stack, and the ZK Stack. As a result, all roll-ups that are not stack-specific can cooperate in aggregating assets for trading between ZK and OP. ZkLink accomplishes this through their settlement layer technology, ZkLink Nexus, which enables incredible data and transaction synchronisation across various Blockchains.

Ethereum’s Liquidity Hub

zkLink Nova is the biggest Layer-3 by the total value or $TVL, according to the L2Beat. The increase is a result of the zkLink’s Aggregation Parade campaign in March 2024 with good user response. Skyward has triple-layer yield rewards during the campaign. It attracted more than 500k addresses and caused the TVL to reach $1 billion (£780 million).

zkLink has recently started an ecosystem grants program in which they allocated 20 million ZKL to foster the growing ecosystem, also, due to the success of zkLink Nova, its associated L2 networks and other leading Web3 wallets like OKX Cryptopedia and Binance Web3 engaged with It.

zkLink aims to become an Ethereum liquidity centre by creating one hub for fragmented liquidity in the form of aggregated roll-ups. Thus, the layer-3 solutions implemented by zkLink provide further opportunities for Ethereum to overcome scaling and fragmentation of liquidity issues. In its attempt to weave a perfect social fabric of scaling and aggregation solutions, zkLink seeks to build a seamless DeFi space that increases user satisfaction and, in the process, directly fuels innovation.
