The rapid expansion of blockchain networks has led to fragmented liquidity in DeFi, challenging its core principle of composability and threatening its scalability.
-
This liquidity fragmentation results in thinner markets, increased slippage, and diminished incentives, impacting user experience and protocol efficiency across multiple chains.

According to Hart Lambur, co-founder of Risk Labs, “Solver infrastructure offers a way out — not by forcing uniformity but by mimicking the experience of synchrony across fragmented chains.”
DeFi’s liquidity fragmentation across multiple blockchains risks weakening composability; solver infrastructure and intents-based models offer scalable interoperability solutions.
Fragmented Liquidity: The Core Challenge Facing DeFi’s Multichain Expansion
Decentralized finance (DeFi) thrives on composable liquidity, where assets flow seamlessly within a unified ecosystem to enable borrowing, swapping, and complex financial strategies. However, the proliferation of Layer 1 blockchains, rollups, and appchains has splintered this once cohesive liquidity pool into isolated pockets. Protocols like Aave and Pendle now operate on multiple chains—17 and 11 respectively—yet the liquidity they command remains largely confined to their specific environments.
This fragmentation introduces significant inefficiencies: markets become thinner, slippage increases, and incentives for both users and protocols weaken. The economic models that performed robustly on Ethereum’s mainnet face challenges when applied to these siloed chains. While multichain deployment addresses Ethereum’s scalability constraints, it simultaneously undermines DeFi’s foundational advantage by diluting liquidity density and composability.
Beyond User Experience: Addressing the Underlying Infrastructure Deficit
Much discourse around multichain DeFi centers on user experience (UX) challenges such as wallet switching, gas token management, and navigating bridge interfaces. Yet these are superficial symptoms of a deeper issue: the absence of a unified execution layer that can seamlessly coordinate crosschain operations. Users attempting crosschain transactions encounter inconsistent interfaces, fragmented pricing, and unpredictable outcomes.
Although swap-and-bridge solutions have improved recently, they still rely on isolated liquidity pools and limited routing options, leading to capital inefficiencies and composability barriers. Without infrastructure that enables liquidity to move fluidly across chains or allows strategies to compose without cumbersome bridging and wrapping, DeFi’s scalability remains constrained.
To bridge this gap, solvers—specialized actors deploying capital and logic—execute complex, fragmented actions on users’ behalf. This approach abstracts away multichain complexity, enabling users to express simple intents like swaps or deposits, which solvers fulfill across diverse chains.
Intents-Based Infrastructure: A Paradigm Shift for Crosschain Interoperability
Intents-based models represent a transformative approach to DeFi composability and liquidity management. The ERC-7683 standard formalizes how crosschain intents are expressed and executed, facilitating “invisible bridging” where users can perform one-click swaps or interactions spanning multiple blockchains without manual intervention.
This infrastructure enables interoperability between historically siloed ecosystems. For example, a user on Solana can seamlessly swap assets into a vault on Arbitrum, or liquidity can flow between BNB Chain and Ethereum-native protocols. Instead of enforcing uniform standards across all chains, intents empower users to define desired outcomes while solvers orchestrate execution across heterogeneous environments.
The result is a resilient multichain ecosystem that preserves the unique strengths of individual chains while enabling global liquidity and composability. This approach does not eliminate multichain complexity but strategically routes around it, maintaining DeFi’s core advantages in a fragmented landscape.
Preserving DeFi’s Future Through Infrastructure Innovation
Multichain DeFi is no longer a theoretical concept but the operational reality. The primary risk is not an abrupt collapse but a gradual erosion of liquidity quality, incentive alignment, and crosschain functionality. Without robust infrastructure solutions, DeFi protocols risk diminished effectiveness and user engagement.
Solver infrastructure and intents-based execution offer a pragmatic path forward. By emulating synchronous execution across fragmented chains, these innovations preserve the composability and liquidity density that underpin DeFi’s success. They enable the ecosystem to scale sustainably while maintaining the flexibility and diversity that characterize the multichain environment.
Conclusion
DeFi’s expansion into a multichain world presents both challenges and opportunities. Fragmented liquidity threatens to undermine composability, but emerging infrastructure solutions like solver networks and intents-based standards provide scalable interoperability without sacrificing local chain strengths. As Hart Lambur emphasizes, embracing these innovations is essential to preserving DeFi’s revolutionary potential and unlocking its next phase of growth.
