CatSwap, a decentralized BRC 2 AMM Swap, has officially launched on the Bitcoin mainnet, enabling trading and liquidity addition for all 6-character BRC 20 tokens as of September 16, 2025. This marks the first native programmable swap for BRC 20 assets on the Bitcoin mainnet, utilizing AMM trading and liquidity pool mechanisms to address previous limitations. The launch is part of the first phase of the BRC 2 protocol upgrade, which began on September 1, 2025, introducing programmability for 6-character tokens. The second phase will expand to include 4/5 character tokens such as ORDI and SATS. Additionally, CatSwap has introduced an ORDI & BRC 20 strategy to enhance ORDI's on-chain liquidity, aiming to attract more liquidity and trading volume to the platform.
