Every significant capital injection serves as a collective vote of confidence in the potential of a sector. On December 11, 2025, Berlin-based cross-chain infrastructure protocol LI.FI announced the completion of a $29 million Series A extension round, led by top crypto venture firms Multicoin Capital and CoinFund.
This marks LI.FI’s second major capital boost since its Series A in 2023, bringing its total funding to approximately $51.7 million. Against the backdrop of frequent cross-chain bridge security incidents, this funding not only arms LI.FI with fresh resources—it also stands as a statement from the capital markets.
01 Funding Overview: Why Are Investors Backing a Protocol That’s Been Attacked?
According to official disclosures, this round brings LI.FI’s total funding to about $52 million. The capital will be used for business expansion and new product development, including AI agents and stablecoin infrastructure, with plans to launch an open intent and solver marketplace in Q1 2026.
Solid business metrics underpin these investment decisions. LI.FI currently employs over 100 people and has processed lifetime transaction volume exceeding $60 billion. In October 2025 alone, monthly volume reached $8 billion.
That figure is roughly seven times the volume from the same period last year, highlighting explosive growth.
02 Business Evolution: From Bridge Aggregation to Universal Liquidity Marketplace
LI.FI’s positioning has evolved significantly. Initially, it functioned as a "cross-chain bridge + DEX aggregator," focused on solving the challenge of "finding the optimal swap route across dozens of chains."
Traditional financial institutions or Web3 applications seeking multi-chain asset trading had to manually integrate with various bridge protocols, DEXs, and aggregators on different chains—a process both costly and technically demanding.
LI.FI’s value lies in abstracting away this complexity. By aggregating cross-chain bridges and DEXs across dozens of public blockchains at the protocol layer, and offering unified APIs, SDKs, or widgets to B2B clients, LI.FI enables seamless "any asset to any asset" cross-chain transactions.
Today, LI.FI has set its sights even higher: building a "universal liquidity marketplace" spanning all chains.
In LI.FI 2.0, released in early 2025, the company noted that with the exponential growth of public chains, rollups, and app chains, simply aggregating bridges and DEXs is no longer sufficient to meet the interoperability needs of a multi-chain ecosystem.
03 Competitive Landscape: Fighting for Routing Power in a Fragmented World
Competition in cross-chain infrastructure is heating up. Multiple protocols are tackling similar challenges with different architectures, and LI.FI stands out for its comprehensive liquidity aggregation model.
Unlike 1inch, which focuses on single-chain swap aggregation, or Symbiosis, which specializes in native cross-chain liquidity solutions, LI.FI’s core advantage lies in the powerful network effects of its aggregation model.
The more bridge protocols and liquidity sources its system integrates, the greater the routing optimization value for users. This structural edge grows as the protocol accumulates more transaction data, raising the barrier to entry for newcomers.
For everyday traders, this means platforms like Gate Exchange can offer more efficient access to multi-chain token exposure, making it easier to tap into liquidity beyond major blockchains.
04 Security Challenges: Lessons Learned and Paths to Improvement
Security is an unavoidable topic in cross-chain operations. According to SlowMist’s hacker incident database, there have been 51 security events involving cross-chain bridges, resulting in over $1.79 billion in economic losses.
LI.FI itself is not without incident. Its smart contracts were attacked twice due to vulnerabilities—in March 2022 and July 2024—resulting in losses of approximately $600,000 and between $10 million to $11.6 million, respectively.
External security reviews indicate both attacks were related to "arbitrary contract calls with unrestricted permissions," essentially trading off some security boundaries for greater flexibility.
For a protocol positioned as "universal liquidity infrastructure," these security incidents serve as serious warnings. On one hand, LI.FI’s aggregation model means any incident can impact the entire B2B client chain. On the other, cross-chain bridges and liquidity aggregation are among the most complex attack surfaces in infrastructure.
05 Market Impact: Why Is Cross-Chain Interoperability the Core Battleground of 2025?
Cross-chain interoperability has emerged as the central infrastructure challenge of this blockchain cycle.
Unlike previous cycles focused on scaling or throughput, today’s Layer 1 and Layer 2 solutions—such as Ethereum, Solana, Arbitrum, and Base—are highly mature. Capital and liquidity are now dispersed across multiple ecosystems, driving demand for efficient capital flow infrastructure.
Multicoin Capital partner Spencer Applebaum stated: "As crypto trading becomes a core feature of mainstream fintech applications, the hardest problem is… enabling fragmented blockchains, liquidity, and execution to collaborate seamlessly."
This $29 million funding round makes it clear that venture capital now views blockchain interoperability infrastructure as the key competitive arena for the future. The technical complexity creates high barriers, protecting established protocols like LI.FI from ordinary competition, while each bridge security incident only increases market demand for reliable, well-capitalized infrastructure.
Outlook
As of December 12, 2025, LI.FI’s partner roster is nearing 1,000 organizations, including industry giants like Robinhood, Binance, Kraken, MetaMask, Phantom, and Ledger.
With fresh funding, LI.FI plans to expand into perpetual futures, yield opportunities, prediction markets, and lending markets. Philipp Zentner stated that beyond business expansion, he intends to use the new capital to hire more staff.
When asked about company valuation, the co-founder and CEO chose not to comment but confirmed that LI.FI is already profitable, with revenue mainly from transaction fee sharing. In the highly uncertain crypto market, projects that can sustain themselves and continuously attract capital may well be the key pillars for building a multi-chain future.
