Fractal Bitcoin Expands to Ethereum With Wrapped FB (WFB) Launch

Fractal Bitcoin has unveiled Wrapped Fractal Bitcoin (WFB), an ERC-20 token designed to bring Bitcoin-native value into the Ethereum ecosystem. The move marks the project’s first step into cross-chain interoperability, with an initial 2.1 million FB locked on the Fractal mainnet and issued as WFB on Ethereum.

Each WFB token is backed 1:1 by FB reserves held on the Fractal network, with all collateral publicly verifiable onchain. In total, 8.4 million FB has been committed to cross-chain ecosystem development, highlighting the scale of Fractal’s strategy to integrate with broader blockchain markets.

According to Lorenzo, a core contributor at Fractal and founder of UniSat Wallet, the launch is intended to strengthen ties across blockchain ecosystems.

“By linking Bitcoin’s strength with Ethereum’s flexibility, and eventually with other networks, we are creating a framework where communities can grow together,” he said. “This is how Bitcoin becomes more accessible, more useful, and more impactful for the entire crypto economy.”

Fractal emphasized that FB itself will remain anchored within the Bitcoin ecosystem, while WFB serves as a wrapper for interoperability. The goal is to give Ethereum-based traders, custodians, and protocols access to Bitcoin-derived value without undermining Bitcoin’s core principles.

For Spencer Yang, another core contributor and managing partner at BlockSpaceForce, WFB is about reducing barriers for market participants.

“Native FB serves Bitcoin-first traders, and WFB plugs into ERC-20 markets that many traders already use,” he explained. “Whether a fund is focused on Bitcoin or Ethereum, Fractal Bitcoin is easy to incorporate through the tools they already use.”

By offering WFB on Ethereum, Fractal expects to broaden trading participation, deepen liquidity, and simplify integrations across custodians and DeFi platforms already equipped for ERC-20 assets.

The WFB release is described as the first phase of a larger cross-chain growth strategy. With Ethereum integration now live, Fractal aims to expand FB’s applications across multiple blockchain ecosystems. The long-term vision is to position FB as a trusted, widely used asset bridging Bitcoin’s security with the programmability of other networks.

Fractal has already established itself as a high-volume ecosystem. According to project data, the network has attracted over 19 million users, processed 4.3 billion transactions, and supported 147 active projects to date. By extending FB’s reach through WFB, the team hopes to accelerate adoption and embed Fractal more deeply into the global blockchain economy.

Wrapped tokens have become an important bridge between blockchain ecosystems, with wrapped Bitcoin (WBTC) already a key part of Ethereum’s DeFi markets. Fractal’s WFB follows a similar model but ties directly to FB, a token native to Bitcoin’s scaling layer. This not only diversifies Bitcoin’s reach but also provides Ethereum traders with new liquidity backed by Bitcoin-based reserves.

If successful, the initiative could help position Fractal as a hub for cross-chain value transfer, demonstrating how Bitcoin-derived assets can integrate with the wider decentralized finance landscape.
