Cross-chain interoperability is reshaping the future of decentralized finance (DeFi), and Avalanche is stepping up its game with a powerful new solution. As users demand faster, cheaper, and more efficient ways to move assets across blockchains, a new third-party bridge—Narni by Umbria Network—is emerging as a compelling alternative to Avalanche’s official Ethereum bridge.
This innovative cross-chain bridge promises to reduce transaction fees by up to 90%, making it significantly more cost-effective for traders and DeFi participants moving liquidity between Ethereum and the Avalanche blockchain.
The Evolution of Avalanche’s Cross-Chain Capabilities
Avalanche (AVAX) is a Layer 1 proof-of-stake (PoS) blockchain known for its high throughput, sub-second finality, and low latency. Since its launch in 2021, it has supported multiple virtual machines, including the Ethereum Virtual Machine (EVM) and WebAssembly (WASM). This multi-VM architecture enables developers to create custom subnets with tailored consensus mechanisms and rulesets—making Avalanche one of the most flexible blockchain platforms available.
To facilitate asset transfers between Ethereum and Avalanche, the official Avalanche-Ethereum Bridge (AEB) was introduced. It allows seamless two-way movement of ERC-20 and ERC-721 tokens, helping bootstrap liquidity and user adoption on Avalanche. However, as the network grew in popularity—and AVAX saw strong market performance—scalability and cost-efficiency demands increased.

This demand paved the way for third-party solutions like Narni, developed by Umbria Network, which aims to overcome the limitations of high gas fees and slow confirmation times.
How Narni Redefines Cross-Chain Efficiency
Narni isn’t just another bridge—it’s engineered for performance. Unlike traditional cross-chain protocols that rely on complex smart contract interactions and multi-signature validators, Narni uses a single-asset liquidity pool model combined with a custom oracle protocol. This architectural innovation reduces computational overhead, streamlining the bridging process and cutting costs dramatically.
According to Umbria Network, these optimizations allow Narni to offer transaction fees that are up to 90% lower than those of the official Avalanche bridge. For users frequently transferring assets between Ethereum and Avalanche—especially during periods of high network congestion—this represents a major financial advantage.
Barney Chambers, Co-Founder and Joint Chief Developer at Umbria Network, emphasized the broader vision behind the project:
“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 with the long-term goal of true blockchain interoperability: a seamless, invisible infrastructure where value flows freely across ecosystems without friction.
Why Lower Fees Matter in DeFi
High transaction costs have long been a pain point in the DeFi space—especially on Ethereum. Despite ongoing upgrades toward ETH 2.0, gas fees remain volatile and often prohibitive for small-scale traders or frequent transactions.
Avalanche, BNB Chain, Solana, and Tezos have all gained traction partly because they offer cheaper alternatives for deploying dApps and moving assets. But without reliable cross-chain infrastructure, users face significant barriers when trying to access these ecosystems.
That’s where efficient bridges like Narni come in. By drastically reducing transfer costs, they:
- Enable micro-transactions across chains
- Improve capital efficiency for yield farmers and liquidity providers
- Lower entry barriers for retail investors
- Encourage broader adoption of multi-chain strategies
As DeFi continues to evolve into a multi-chain reality, minimizing friction between networks becomes critical. Bridges aren’t just tools—they’re foundational components of the next-generation financial web.

Frequently Asked Questions (FAQ)
What is the Narni bridge?
Narni is a third-party cross-chain bridge developed by Umbria Network that enables fast and low-cost transfers of assets between Ethereum and Avalanche. It leverages a single-asset liquidity model and custom oracle system to reduce transaction fees by up to 90% compared to the official Avalanche-Ethereum Bridge.
Is Narni safer than the official Avalanche bridge?
While the official bridge is audited and directly supported by the Avalanche team, Narni implements robust security measures including decentralized oracles and non-custodial design. Users should always review audit reports and understand the trade-offs between speed, cost, and decentralization when choosing a bridge.
Can I transfer any token using Narni?
Narni supports ERC-20 and ERC-721 tokens that are compatible with both Ethereum and Avalanche’s EVM environment. However, not all tokens may be immediately available—check the platform’s supported assets list before initiating a transfer.
Why are cross-chain bridges important for DeFi?
Cross-chain bridges allow users to move liquidity across different blockchains, unlocking access to diverse DeFi applications, yield opportunities, and ecosystems. They are essential for achieving true interoperability in a fragmented blockchain landscape.
Does using Narni require technical expertise?
No. Narni is designed with user experience in mind. Most transfers can be completed through a simple web interface without requiring advanced knowledge of smart contracts or blockchain mechanics.
How does Narni achieve lower fees?
By using a single-asset liquidity pool architecture and a custom oracle protocol, Narni minimizes computational complexity and smart contract overhead—two major contributors to high gas costs on traditional bridges.
The Road Ahead: Toward Invisible Blockchain Infrastructure
The rise of efficient, low-cost bridges like Narni signals a shift in how users interact with blockchain technology. As interoperability improves, the focus will increasingly shift from which chain to what you can do.
In this vision, platforms like Avalanche serve not just as standalone ecosystems but as interconnected nodes in a larger financial network. With continued innovation in cross-chain technology, we’re moving closer to a world where blockchain choice is abstracted away—delivering a smoother, faster, and more inclusive digital economy.
