High transaction fees on Ethereum, often referred to as "gas fees," are a significant obstacle for decentralized finance (DeFi) adoption. These fees stem from network congestion and Ethereum's consensus mechanism, which prioritizes transactions based on fee bids. While Ethereum offers unmatched security and decentralization, the high costs push users toward cheaper but often less secure alternatives. Many critical DeFi protocols are built on Ethereum, making migration impractical for developers. A potential solution could involve creating a gas-efficient Layer 2 network that retains Ethereum’s security while drastically lowering costs.

How It Could Work

One approach might involve using rollup technology, such as Optimistic or ZK-Rollups, to batch transactions off-chain and submit proofs to Ethereum. This could reduce fees significantly while maintaining security. The system could also be designed to be fully compatible with Ethereum’s Virtual Machine (EVM), allowing developers to migrate existing applications with minimal changes. To attract users from other blockchains, bridges could be integrated with competing networks like Polygon or Avalanche. A dynamic fee model could adjust costs based on demand, letting users choose between speed and affordability.

Retail users could benefit from lower fees for small transactions like NFT purchases or token swaps.
Developers could retain Ethereum’s security without alienating users with high costs.
Institutions might prefer this over centralized alternatives due to its security and efficiency.

Potential Advantages Over Existing Solutions

Compared to existing Layer 2 solutions like Arbitrum or Optimism, this approach could differentiate itself by emphasizing cross-chain interoperability, making it easier to move assets between different blockchains. Unlike sidechains like Polygon, it would use rollup technology for better security. And unlike standalone chains like Solana, it would preserve Ethereum’s decentralization while offering competitive fees. By focusing on seamless EVM compatibility and niche use cases like gaming or NFTs, it could carve out a unique position in the market.

An initial version could start with a testnet supporting basic transactions and smart contracts, followed by developer grants to encourage adoption. Partnerships with major DeFi projects could help bootstrap liquidity, while a token model could incentivize participation through governance and fee discounts.
