Fiber offers free transactions for users by default. The chain fees are subsidized by the intrinsic economic value created by the chain (MEV). Unlike traditional blockchains where users compete for scarce blockspace and are forced to hold gas just to participate, Fiber is built with abundant blockspace and protocol-level mechanisms that remove unnecessary friction from everyday usage. The result is simple:
users can interact with applications on Fiber without holding tokens, bridging assets, or preconfiguring wallets.

​
Why Free Transactions Matter

Gas fees are one of the largest onboarding barriers to real adoption in crypto. On ALL other networks, users must:
  • acquire gas tokens before their first interaction
  • bridge assets just to pay fees
  • manage fluctuating costs that break the flow of mobile and consumer UX
This complexity disproportionately harms:
  • new users
  • mobile-first users
  • users in emerging markets
Fiber removes this friction by design.

​
How Free Transactions Work

On Fiber, the base gas fee is not enforced by default.
  • Blockspace is intentionally abundant
  • There is no mandatory minimum gas price (e.g. no forced 1wei floor)
  • **Making a free transaction is simple - just set the gas fee to **0.
This allows applications to offer:
  • instant onboarding
  • seamless mobile experience
  • interactions that feel closer to Web2 UX without sacrificing decentralization
Free transactions are the default experience for users - not special cases.

​
When Fees May Apply

Free transactions are designed for normal network conditions. In periods of extremely high activity, fees may temporarily emerge as a congestion control mechanism to ensure network stability and fair ordering. This ensures:
  • predictable performance under load
  • protection against spam
  • long-term sustainability of the network
Even in these cases, fees are expected to remain minimal compared to traditional chains.

​
Validator Incentives & Sustainability

Free transactions do not mean validators are ignored or under-incentivized. Instead of relying solely on per-transaction fees, Fiber aligns validator incentives with long-term network value creation. Validators are compensated through:
  • participation in MEV-aware execution flows
  • economic activity generated by real usage
  • long-term value accrual to the Fiber token as the network grows
Free transactions lower the barrier to entry, increase usage, and expand the economic surface area of the network — which ultimately benefits validators and token holders alike. Fiber optimizes for sustainable value creation, not short-term fee extraction.
