CRC-20 is a covenant token protocol designed for Bitcoin Layer 1, and leaf presents the protocol’s first token. The project says that 1 billion LEAF were minted through Taproot covenants, with peer-to-peer trading available through crc.garden. Its website introduces CRC-20 through an interactive history of Bitcoin technologies, tracing developments from Bitcoin’s UTXO model and script upgrades to Taproot, covenants, token experiments and client-validated systems.

The project also provides educational and technical resources, including a protocol yellow paper, a white paper, a technical research thread and materials related to PRECOP, the implementation supporting the leaf application overlay. These resources explain the system’s mechanics, commitments and execution assumptions, and outline its intended path toward covenant execution. The site positions CRC-20 within ongoing research into Bitcoin programmability, while distinguishing its approach from earlier application-layer token conventions such as BRC-20. Users can explore protocol activity, a market and a wallet through the site’s navigation.
