Fraxtal RPC Endpoint

Fast, flat-rate Fraxtal RPC node provider — free tier, no KYC, HTTP & WebSocket.

Fraxtal is a Layer 2 network from Frax Finance built on the OP Stack, designed as the settlement layer for the Frax ecosystem. It uses a native gas token in the FRAX family rather than ETH.

About Fraxtal

Fraxtal launched its mainnet in February 2024, with public bridge access opening the following month. It is built on the OP Stack and is intended to align with the Optimism Superchain while serving Frax's stablecoin and DeFi products.

Unlike most OP Stack L2s, Fraxtal does not use ETH for gas; following Frax's North Star upgrade and the FXS-to-FRAX rebrand in late 2025, FRAX serves as the network's native gas and staking asset, while the project's stablecoin transitioned to the frxUSD name. Fraxtal also runs the Flox blockspace incentive system, which rewards users and contract developers with FXTL points based on gas spent.

Common Use Cases on Fraxtal

• Frax stablecoin (frxUSD) settlement
• DeFi protocols
• Liquid staking (sfrxETH and related assets)
• Blockspace incentive farming (Flox / FXTL)
• EVM smart contract deployment
• Bridged liquidity

Fraxtal Ecosystem

Fraxtal anchors the Frax Finance ecosystem, including frxUSD, frxETH/sfrxETH, Fraxlend, and Fraxswap, alongside third-party DeFi deployments and the Flox incentive program.
