LI.FI

LI.FI is a multi-chain liquidity aggregation protocol designed to simplify asset swaps and transfers across various blockchain networks. Founded in 2021 and headquartered in Berlin, Germany, the company was established by Philipp Zentner and Max Klenk, who have a decade-long history of building companies together. LI.FI was created to address the fragmentation of liquidity and infrastructure in the decentralized finance (DeFi) ecosystem by providing a unified solution for developers and users.

The company operates as a middle layer between DeFi infrastructure and decentralized applications (dApps), connecting to a wide array of liquidity sources, including decentralized exchanges (DEXs), bridges, and solver networks. Through a single API integration, LI.FI allows dApps to offer their users optimal routes for any-to-any swaps without the complexity of integrating multiple protocols individually. The protocol's smart routing algorithm evaluates potential paths based on factors like transaction costs and security to recommend the most efficient route. This aggregation model is intended to provide a more secure and enhanced user experience compared to single-bridge solutions.

LI.FI's business model is primarily B2B, catering to developers, dApps, and enterprises. It provides a suite of tools, including a Software Development Kit (SDK), an API, and a customizable widget, which enable the integration of cross-chain functionality into various applications. The company generates revenue through transaction fees, taking a percentage of each successful cross-chain operation it facilitates. For enterprise clients with higher transaction volumes, LI.FI offers custom rate limits and personalized support. The protocol serves a wide range of partners, including MetaMask, Phantom, Robinhood, and Ledger.

Since its inception, LI.FI has achieved significant milestones, including surpassing $60 billion in lifetime transaction volume. The company has secured a total of $52 million in funding over three rounds, with its latest Series A extension raising $29 million, led by Multicoin and CoinFund. In early 2025, LI.FI acquired Catalyst to advance its intent-driven trading and cross-chain liquidity capabilities. The platform supports numerous EVM-compatible chains and has expanded to include non-EVM chains like Solana and Bitcoin.
