According to Odaily, Fractal Bitcoin has announced on platform X that OP_CAT represents a significant potential improvement in Bitcoin script programmability. Technically, the team is prepared to offer OP_CAT on Fractal Bitcoin and is considering activating it when the mainnet goes live in September. This activation will enable projects to implement advanced contract functions on Fractal from day one.

As an extension of the Bitcoin blockchain, one of Fractal Bitcoin's use cases is to enable experimental features like OP_CAT. This will open up numerous programmable possibilities and provide Bitcoin core developers with real-world lessons before re-enabling such changes on the Bitcoin mainnet. By conditionally executing scripts that enable OP_CAT within the TapRoot environment, these functions can be performed without disrupting transaction-level compatibility between different layers.
