Saga Launches Cross-Chain Liquidity Layer, Transforms Blockchain Economics and Eliminates Gas Fees

The liquidity integration layer enables seamless asset movement across chains, replacing convoluted bridging and gas fees with a streamlined model that grows transaction volume.

SAN FRANCISCO--(BUSINESS WIRE)--Saga, the Layer 1 blockchain protocol to launch Layer 1s, today addressed one of DeFi’s largest hurdles with the launch of its Liquidity Integration Layer (LiL), a first-of-its-kind system that automatically connects and routes liquidity between different blockchain networks and applications. Eliminating fragmentation, LiL creates a unified environment where assets can move freely without relying on traditional bridge infrastructure creating a stronger, more efficient ecosystem. This approach also enables a shift away from per-transaction gas fees to a model based on liquidity flow.

In blockchain's current state, with over $120 billion in assets currently siloed across dozens of separate chains, fragmented liquidity creates significant barriers for both users and developers. Users face higher costs and complexity when moving assets between chains, while developers must manage complex infrastructure across multiple networks, with industry data showing 30% of teams splitting their deployments across different ecosystems. LiL addresses these challenges by providing automatic connectivity and routing between chains, eliminating the need for manual bridge setups that have suffered billions in losses.

The launch builds upon Saga's December 2024 Mainnet 2.0 release and deployment of Uniswap V3, which created the first gasless trading experience on a decentralized exchange. Through LiL, Saga moves away from charging per-transaction fees, instead generating revenue by capturing a percentage of the total value flowing through the network - similar to how payment networks derive revenue from transaction volume rather than charging users directly.

"The blockchain industry's reliance on gas fees and fragmented liquidity has created significant barriers to adoption," said Jin Kwon, Co-founder of Saga. "Users shouldn't need to acquire different tokens just to complete basic transactions, and developers shouldn't have to choose between scalability and access to liquidity. LiL fundamentally changes this by creating a unified environment where applications can scale without sacrificing connectivity."

LiL achieves this through four key technical innovations:

• Automatic bridges that connect all Saga chainlets without manual setup, allowing applications to instantly access the broader network
• A central routing system that optimizes liquidity flow by finding the most efficient paths for moving assets between applications
• Packet-forwarding middleware that automates complex cross-chain transactions, enabling users to move assets between different chains in a single step rather than managing multiple transfers
• Smart contract functionality that enables applications to interact seamlessly across different chains

For developers, this means:

• Launch with immediate access to network-wide liquidity
• Scale applications without traditional gas constraints
• Deploy cross-chain applications without managing multiple bridges
• Generate revenue without charging users transaction fees

"This represents a fundamental shift in how blockchain networks can operate," said Rebecca Liao, Co-Founder and CEO at Saga. "By deriving value from liquidity flow rather than infrastructure costs, we create an environment where early-stage projects can experiment freely, successful applications can scale efficiently, and users never have to think about gas fees."

Twenty pioneering projects are already participating in the LiL Beta Program across DeFi, gaming, and AI applications. These include Metropolis, which develops protocols for automated AI agent trading across different chains, and various DeFi applications building core financial services. The Uniswap deployment demonstrates how LiL enables new possibilities in DeFi, allowing users to trade tokens without managing gas fees across different chains.

Supporting the LiL launch are infrastructure partners Evmos, providing the Ethereum Virtual Machine runtime for Saga's chainlets, and Squid Router, extending token swapping and routing services to Saga's ecosystem.

Looking ahead, Saga plans to introduce additional DeFi primitives and foundational financial tools, including perpetual contracts, lending protocols, and yield optimization services. These developments will showcase how LiL's infrastructure enables entirely new categories of DeFi applications previously constrained by traditional blockchain economics.
