Fiber is engineered for applications that require instant execution, reliability, and decentralization, without relying on centralized sequencers, rollups, or hidden control points. The chain is designed from the ground up to support real-time, mobile-first finance, serving as a true alternative to centralized financial infrastructure and applications. It offers:
  • Real-time Transactions via Preconfirmations
    Transactions confirm in milliseconds, enabling applications that require instant feedback and real-time execution — including trading and mobile-native use cases.
  • Free transactions by design
    All transactions on Fiber require zero gas fees by default. Users can interact with apps without holding tokens, bridging assets, or preconfiguring wallets — making mobile onboarding truly seamless. The chain is subsidized by MEV actors.
  • Fully EVM-native
    Solidity and Ethereum tooling work out of the box, giving builders immediate access to the ecosystem where most smart contract development and onchain activity already lives.
  • Permissionless and decentralized
    No sequencers. No rollups. No centralized chokepoints.
    Anyone can run a validator to secure and support the Fiber chain.
  • Built for finance-first applications
    Trading, DeFi, and onchain-native financial apps that need speed, reliability, and global accessibility.
Fiber is infrastructure designed not just to scale technically — but to scale to real users.

What Makes Fiber Different

Most blockchains today optimize for early adopters and power users: desktop-heavy workflows, complex setup, fragmented tooling, and assumptions that don’t hold for real-world usage. Fiber takes a different approach.
  • Mobile-first
    Fiber is designed with mobile usage as a first-class constraint, not an afterthought. Zero gas fees, instant feedback, and simple onboarding make it practical for users who primarily interact through their phones — which represents the majority of the world.
  • Real-time - not just “fast enough”
    Instead of optimizing for throughput benchmarks, Fiber optimizes for responsiveness. Transactions feel immediate, which is critical for trading, financial interactions, and user trust.
  • Decentralization without tradeoffs
    Fiber avoids the common pattern of introducing centralized execution layers to achieve performance. Speed does not come at the cost of permissionlessness or validator accountability.
  • Economics aligned with usage
    Blockspace on Fiber is abundant. Transactions are free by default, and the network is subsidized by economic activity rather than user fees — aligning incentives around adoption and real usage, not rent extraction.
  • Built for builders and users
    Fiber removes friction for developers experimenting and deploying, while also delivering experiences end users actually enjoy using. Both are necessary for sustainable ecosystems.
