Fraxtal

Fraxtal is Frax Finance’s modular Layer‑2 blockchain built atop the Optimism (OP) stack. It functions as an EVM-equivalent rollup and introduces “fractal scaling,” enabling other chains or L3s to plug into its middleware and shared DA/security layer. The network uses FRAX and frxETH as its gas tokens, fully integrating the Frax ecosystem into L2 operations.

What Makes Fraxtal Distinct?

• FRAX-Powered Gas Layer: Fraxtal is one of the only rollups where you don’t need ETH to pay for gas. You pay with FRAX (and optionally frxETH), creating an internal demand sink for the Frax economy.

• FXTL and Flox: Fraxtal introduces a native incentive system called Flox, which distributes FXTL points to contracts and users based on gas consumption per epoch. Unlike retroactive airdrops, this is ongoing, predictable, and quantifiable. FXTL can later be converted or staked as part of future governance and rewards pipelines.

• Fractal Scaling: The name Fraxtal isn’t just a pun. The protocol is designed to support child rollups—mini-Fraxtals—that can plug into its consensus and DA layer. Think L2-as-a-service, with Frax’s economic primitives baked in.

• DeFi-Native Design: Everything in Fraxtal is designed around economic activity. Oracles, AMM hooks, collateral modules, and staked liquidity—every contract is optimized for throughput and composability.

• Modular Data Availability: Built on the OP Stack but not dependent on a single DA provider. The Frax team is exploring integration with Celestia and EigenDA for sovereign availability.

Governance and Incentives

There’s no Fraxtal without Frax. FXTL is not a token (yet), but rather a points system that defines future allocation of Frax incentives. It's already a powerful lever for rewarding usage over speculation, ensuring that those who drive volume, not just bridge capital, get rewarded.

veFXS holders—long-time governance stakers in the Frax ecosystem—also play a role. They've received FXTL allocations and have governance say over emission models and partnership activations on Fraxtal.

A Network Designed to Expand

Fraxtal doesn’t isolate itself. It’s built with interoperability as default, and Frax’s history of operating on over a dozen chains means that Fraxtal is optimized for bridging:

• Native Bridge to Ethereum

• Optimism Superchain compatibility

• Shared FXTL accounting with partner chains

• Modular support for L3s and appchains using Fraxtal’s stack

• Integration with LayerZero, Axelar, and Wormhole for liquidity and message passing

Ecosystem and Infrastructure

Fraxtal launched with heavy support from both DeFi powerhouses and infra leaders. At launch, it was supported by:

• Fraxscan: A custom Etherscan fork

• Curve: Planning to deploy with native FRAX incentives

• Balancer, Sushi, and Maverick: Exploring integrations

• Chainlink and Pyth: For oracle feeds

• Redacted Cartel, Conic, Vela, Origin, Liquity: Building or migrating to Fraxtal for FXTL alignment

• Bridges and L2 portals: Including LayerZero and third-party rollup as a service platforms
