Unlocking CAT20 with comprehensive tools: Wallet, Indexer, & Marketplace
Since its introduction, CAT20 tokens have sparked excitement and innovation.
CAT20 is a groundbreaking standard based on the activation of OP_CAT on Fractal Bitcoin. Thus, understanding how users can interact with it through various tools — like wallets, indexers, and marketplaces — is key to unlocking its full potential.
What is CAT20?
CAT Protocol, short for Covenant Attested Token, is unique in its miner validated structure and that it’s UTXO-based. It requires the activation of the opcode, OP_CAT, which is enabled on Fractal.
CAT Protocol’s first release on September 11, 2024 was its own CAT20 token, CAT. Subsequently, CAT721 will be released.

Wallets, Indexers, and Marketplace
UniSat, one of the core contributors of Fractal, has recently announced full support for CAT in its wallet, indexer, and marketplace products. These products serve as an entry point for users who are interested in engaging with the CAT protocol, and the Fractal team is excited to see more products making it easier for users to interact with CAT.
A key feature of the CAT20 wallet is the ability to merge CAT20 UTXOs directly and efficiently within the wallet. As stipulated in the CAT protocol, each transaction can include up to four UTXOs, making this merging process essential when larger amounts need to be sent in a single transaction.

For indexers, UniSat Explorer now fully supports the display of CAT20 assets and their related transactions. This provides transparency and accessibility for users and developers alike. You can explore this feature here: UniSat Explorer.
The CAT marketplace operates as a trustless, permissionless, Bitcoin script-based on-chain CAT20 trading platform. This trustless environment enhances user control and minimizes security risks, while the permissionless nature allows anyone globally to participate in token trading without barriers or prior approval. Supporting both buy and sell orders, it offers more versatility than traditional methods like PSBT, making it a key driver for broader adoption and innovation within the CAT20 ecosystem.

Stay tuned as more features for the CAT protocol, including support for CAT721 and CAT dApps, are expected to roll out in December. You can check our roadmap here: Fractal Roadmap.
CAT Ecosystem
As the CAT ecosystem continues to grow, we can expect to see further innovations in how tokens are issued, tracked, and exchanged. For now, the pieces are falling into place to make CAT20 tokens a major force within the broader cryptocurrency landscape, empowering users and developers alike to build on Fractal and Bitcoin’s secure foundation.
We are excited to see more tooling being built around the CAT ecosystem, and are actively working on updated developer documentation and tools to make it easier to build using OP_CAT. Please stay tuned for more updates here!
