Deep Dive
1. EigenDA Migration (15 July 2025)
Overview: Fuel migrated its data availability layer from Ethereum to EigenDA, reducing costs and increasing transaction capacity from 600 to 5,000 TPS in devnet environments.
This upgrade addresses the bottleneck of storing transaction data on Ethereum, which previously consumed ~60% of rollup operational costs. EigenDA’s modular design allows Fuel to process transactions in parallel using multiple CPU cores, laying groundwork for a roadmap targeting 150,000 TPS.
What this means: This is bullish for FUEL because it lowers operational costs for dApps and positions Fuel as a high-throughput contender in the Layer 2 race. Users benefit from faster, cheaper transactions as the network scales.

2. Sway Package Registry (7 July 2025)
Overview: Launched sway-libs, a package manager for Fuel’s SwayLang, streamlining code reuse for developers.
The registry eliminates manual GitHub code copying by allowing developers to import pre-built modules (e.g., oracles, token standards) via forc add. Early benchmarks show a 40% reduction in development time for common DeFi primitives.
What this means: This is bullish for FUEL because it lowers barriers to ecosystem development. Easier tooling could attract more builders, accelerating dApp diversity and network usage.

3. Fuel Forge Features (28 July–7 August 2025)
Overview: Announced Fuel Forge, a suite for advanced DeFi, including ZK-powered perpetuals and wallet-embedded mini-apps.
The update enables:
- Zero-knowledge proofs for private trading positions
- Pre-confirmations for near-instant DEX trades
- Intent-based swaps that auto-route across liquidity pools
What this means: This is bullish for FUEL as it directly competes with incumbent DeFi platforms by combining privacy, speed, and UX improvements—key drivers for user adoption.

Conclusion
Fuel’s codebase updates prioritize scalability (EigenDA), developer adoption (Sway registry), and DeFi innovation (Forge). Together, they position FUEL as a modular execution layer capable of supporting high-demand applications. With the network now processing 5,000 TPS and DeFi tooling expanding, will Fuel’s technical edge translate into ecosystem growth amid fierce L2 competition?
