Fractal is excited to announce the launch of PizzaSwap, the first DEX to be built concurrently on both Bitcoin and Fractal Bitcoin, aiming to support all asset types across these networks and more.

This marks a significant milestone in expanding the utility of Bitcoin-native assets by enabling users to seamlessly swap assets and provide liquidity — all while maintaining Bitcoin's native security and decentralization.

Whether you're a trader or a liquidity provider, PizzaSwap is a fully open-sourced DEX that offers a seamless, fast, and decentralized platform to engage with all native assets on Bitcoin and Fractal.

Learn how to interact with PizzaSwap with our comprehensive documentation here.

What is PizzaSwap?

PizzaSwap is designed as a fully decentralized swapping protocol, allowing users to:

Swap assets directly without intermediaries.
Provide liquidity to liquidity pools and earn rewards.
Track past transactions on an easy-to-use interface.

PizzaSwap enables users to trade and earn with minimal fees and a straightforward interface. Its automated market maker (AMM) system ensures that trades are always executed with an algorithmically determined price, without needing a counterparty.

How PizzaSwap Works

Like most decentralized exchanges (DEXs), PizzaSwap allows users to deposit assets into liquidity pools. These pools then facilitate trades between different assets using a formula-driven approach (x * y = k).

Fees on PizzaSwap

Service Fee: Every swap incurs a 0.3% transaction fee. 1/6 of this fee goes to the platform, while the rest is distributed among liquidity providers (LPs). Fees are collected in bSATS.
Rollup Fee: To minimize network fees, PizzaSwap implements a rollup fee that bundles transactions into a single submission to either the Bitcoin or Fractal network, reducing costs for users.

These fees ensure that liquidity providers are rewarded and transaction costs remain low, making PizzaSwap an attractive platform for both traders and LPs.

Assets that PizzaSwap Supports

At launch, PizzaSwap will support the following assets:

🔸 brc-20 tickers on Fractal (people, GLIZZY, MoonCats)

🔸 Bridged brc-20 (bORDI, bSATS)

🔸 Bridged Bitcoin (bBTC)

More tickers will be available in the future.

The following assets will be supported in future updates:

SimpleBridge will open on October 2nd, along with the announcement of supported tickers. (sORDI, sBTC, sSATS and more)
Fractal FB as brc-20 (i.e. sFB)
Runes on Fractal (upon Runes activation)
Bridged Runes (upon Runes activation)

Please note that support for Runes and bridged Runes will begin after the Runes activation at block height 84,000.

How to Get Started with PizzaSwap

To use PizzaSwap, users will need to connect their brc-20-supported wallet, such as UniSat Wallet. Once connected, users can deposit their assets into the swap module and begin swapping or providing liquidity to earn rewards. For more information, check out our guide to get started on PizzaSwap.

Risk Considerations

While providing liquidity can be rewarding, users should be aware of potential risks like impermanent loss and price impact, especially when dealing with large trades.

PizzaSwap mitigates some of these risks through its efficient AMM system and allows liquidity providers to monitor their LP positions.

PizzaSwap's Role in Fractal's Ecosystem

PizzaSwap is more than just a swap mechanism; it’s a key part of Fractal’s goal to unlock new capabilities for Bitcoin-native assets. With faster transaction times and low fees, PizzaSwap enables users to leverage the full potential of Bitcoin’s security while enjoying a seamless trading experience.

As Fractal scales, PizzaSwap will play a crucial role in expanding DeFi opportunities and facilitating a robust ecosystem of decentralized applications.
