brc-20 Swap and PizzaSwap Development

Before introducing PizzaSwap, it’s essential to understand its roots in brc-20 Swap on Bitcoin Mainnet. As a cornerstone of UniSat’s efforts to push the adoption of brc-20 protocol, we developed the brc-20 Swap alpha on Bitcoin mainnet in November 2023.

Even though the swap on Bitcoin was not able to fully open due to circumstances beyond our control, we’re not giving up. What we learnt from the process paved the way for PizzaSwap- a mirror of the brc-20 swap module on Bitcoin deployed on Fractal Bitcoin- an extension of Bitcoin that is immensely similar to Bitcoin itself.

We’re committed to continuously enhancing the PizzaSwap experience for our users, keeping it secure, efficient, and user-friendly. This timeline traces the journey of brc-20 Swap and PizzaSwap, culminating in our vision for 2025.

brc-20 Swap on Bitcoin Mainnet 🔗

  • 2023: Pioneering brc-20 Swap

    • UniSat launched brc-20 Swap on Bitcoin Mainnet in 2023 after extensive testing throughout 2022-2023.

    • Significant effort and innovation went into ensuring this product functioned correctly on Bitcoin’s mainnet, laying the groundwork for decentralized swaps.

  • 2024: Standardizing with L1F

    • Throughout 2024, we worked closely with L1F to integrate brc-20 Swap into the brc-20 standard upgrade. Due to the need for cross-team coordination, the process took longer than expected, but we remained committed to ensuring a smooth and secure implementation.

  • 2025: Upcoming major protocol upgrades

    • We continue to work closely with all stakeholders to push forward the brc-20 update, which will introduce three key modules:

      • Single-step TRANSFER

      • Programmable Module

      • Swap Module
