The Avalanche blockchain is taking a major step toward improving cross-chain interoperability and reducing transaction fees with the integration of a new third-party bridge solution. As decentralized applications (dApps) continue to expand across multiple blockchains, the need for efficient, low-cost asset transfers has never been greater. Enter Narni, a next-generation cross-chain bridge developed by Umbria Network, designed specifically to streamline liquidity movement between Ethereum and Avalanche—cutting costs by up to 90% compared to the official AVAX bridge.
This advancement positions Avalanche as a more scalable and user-friendly Layer 1 (L1) blockchain, especially for traders and DeFi users seeking faster and cheaper alternatives to Ethereum’s congested mainnet.
The Evolution of Avalanche’s Cross-Chain Capabilities
Avalanche, a proof-of-stake (PoS) blockchain launched in 2021, supports multiple virtual machines—including the Ethereum Virtual Machine (EVM) and WebAssembly (WASM). This multi-VM architecture enables developers to create customized subnets with tailored consensus mechanisms and performance characteristics, making Avalanche highly adaptable for diverse use cases.
To facilitate early interoperability with Ethereum, Avalanche introduced its official Ethereum bridge, allowing bidirectional transfer of ERC-20 and ERC-721 tokens. While functional, this native bridge has faced criticism for relatively high gas fees and slower transaction finality during peak network usage.

As the AVAX ecosystem grew—driven by rising adoption and increased value of its native token—demand surged for more efficient cross-chain solutions. This demand paved the way for third-party innovations like Narni by Umbria Network.
How Narni Redefines Cross-Chain Efficiency
Narni isn’t just another bridge—it’s a reimagined approach to cross-chain liquidity transfer. By leveraging a single-asset liquidity pool model and a custom oracle protocol, Narni significantly reduces the computational overhead typically associated with bridging assets across chains.
Key Advantages of Narni Bridge:
- Up to 90% lower transaction fees than the official Avalanche-Ethereum bridge
- Faster settlement times due to optimized validation processes
- Reduced smart contract complexity enhances security and reliability
- Seamless integration with existing wallets and DeFi platforms
Barney Chambers, co-founder and co-lead developer at Umbria Network, emphasized the broader vision behind the project in an interview with Cointelegraph:
“Umbria is the glue between all L1 and L2 blockchains, enabling users to move their assets cheaply and quickly. In the future, we envision a world where users don’t even need to know which blockchain they’re using.”
This philosophy aligns perfectly with Avalanche’s mission: to provide a scalable, interoperable, and developer-friendly environment that lowers barriers to entry in the decentralized web.
Why Lower Bridge Fees Matter for DeFi Growth
High gas fees on Ethereum have long been a bottleneck for decentralized finance (DeFi). Even with Layer 2 scaling solutions gaining traction, many retail users are still priced out during periods of high network congestion.
Avalanche offers a compelling alternative. With sub-second finality and significantly lower transaction costs, it has become a preferred destination for yield farmers, liquidity providers, and NFT traders. However, the cost of moving assets to Avalanche remained a friction point—until now.
By slashing bridge fees by up to 90%, Narni removes one of the last economic hurdles for users looking to leverage Avalanche’s high-performance infrastructure. Whether you're swapping tokens, participating in liquidity pools, or minting NFTs, reduced entry costs mean higher net returns and improved user experience.

Frequently Asked Questions (FAQ)
Q: What is a cross-chain bridge?
A: A cross-chain bridge is a protocol that enables the transfer of assets or data between two different blockchains. For example, moving ETH or ERC-20 tokens from Ethereum to Avalanche allows users to access faster transactions and lower fees on the destination chain.
Q: How does the Narni bridge reduce transaction costs?
A: Narni uses a single-asset liquidity pool system and a proprietary oracle network to minimize computational load and smart contract interactions—two primary drivers of high gas fees in traditional bridges.
Q: Is the Narni bridge safe to use?
A: While no bridge is entirely risk-free, Narni is built by Umbria Network with security audits and modular design principles. Users should always verify contract addresses and use trusted interfaces when interacting with any cross-chain protocol.
Q: Can I use Narni with my MetaMask wallet?
A: Yes. Since Narni supports EVM-compatible chains like Ethereum and Avalanche, it works seamlessly with MetaMask and most major Web3 wallets.
Q: Does Avalanche have its own official bridge?
A: Yes, Avalanche launched its official Ethereum bridge in 2021. However, third-party solutions like Narni offer enhanced efficiency, lower fees, and faster transfers.
Q: Why is reducing transaction cost important for DeFi?
A: Lower fees increase accessibility for retail investors, improve capital efficiency for liquidity providers, and make micro-transactions viable—key factors in driving mass adoption of decentralized finance.
The Future of Interoperability on Avalanche
As blockchain ecosystems become increasingly fragmented, interoperability will be the cornerstone of Web3 growth. Solutions like Narni demonstrate how third-party innovation can complement official infrastructure to deliver superior user experiences.
Avalanche’s support for subnet customization, combined with emerging cross-chain tools, creates a powerful foundation for institutional-grade applications, gaming platforms, and global payment systems—all operating across secure, interconnected networks.
Moreover, as ETH 2.0 adoption progresses slowly and gas volatility persists, alternative L1s like Avalanche will continue gaining traction. Efficient bridges are no longer optional—they’re essential infrastructure.
