10 Ggas/s
High transaction throughput thanks to optimized block pipeline and 250ms blocks.
Native EVM
Deploy Ethereum contracts as-is. Zero migration overhead. Complete tooling compatibility.
Fully Decentralized
Open-source protocol. Permissionless validation. Community-driven governance.
Unique fiber features
Transaction metadata
Includes custom transaction metadata, a string of bytes that can be attached to any transaction.
Revert protection
Native revert protection mechanism that allows users to block transactions that revert.
Gasless transactions
Processes gasless transactions (0 gwei) because free transactions are a public good.
Transaction hooks
Execute custom logic offchain to create new protocols. Enable decentralized auctions.
Transaction Hooks Use Cases
Transaction hooks enable powerful new primitives for DeFi and beyond. Hooks are enforced at the consensus layer. Here are some of the innovative use cases made possible by fiber's transaction hooks.
Decentralized Limit Orders
Create limit orders that execute automatically when price conditions are met, without relying on centralized infrastructure or keepers.
Just-in-time Liquidity
Provide liquidity exactly when needed for specific transactions, maximizing capital efficiency and minimizing impermanent loss.
Native Bundles
Using transaction hooks, MEV operators can bundle transactions in the mempool.
MEV Protection
Build protocols that protect users from harmful MEV extraction by enforcing fair execution conditions at the protocol level.
Conditional Transactions
Execute transactions only when specific on-chain conditions are met, enabling complex financial instruments and automated strategies.
Repeatable transactions
Build repeatable transactions that can be executed multiple times with the same parameters, without the need for a centralized keeper.
Why fiber
fiber is the best of the blockchain trilemma: speed, security, and decentralization. Built by developers, for DeFi, it enables the next generation of high-performance dApps without sacrificing Ethereum's battle-tested ecosystem. fiber is build directly on the foundation of Ethereum using the Reth SDK and a custom implementation of the PBFT consensus protocol.
fiber is built by the team behind merkle, the leading MEV company.

FBR Token
The FBR token is the native token of the fiber network, with a fixed maximum supply of 25 million tokens.
Maximum Supply
This fixed supply ensures scarcity and helps maintain the token's long-term value proposition. The token will be issued per block, halving every 6 months.
