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

fiber is built to enable fair and efficient markets in a decentralized adverserial environment.

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.

Roadmap

February 1rst 2025

Internal testnet launch

April 8th 2025

Public testnet

TBA

Mainnet launch

FBR Token

The FBR token is the native token of the fiber network, with a fixed maximum supply of 25 million tokens.

25M

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.

It's time to build.
