# What is SRC-20

SRC-20 is an intriguing experiment that defines social inscriptions by introducing new metadata, asset formats (posts, likes, reposts), and a recursive approach. These formats are entirely open-source, allowing anyone to deploy, mint, transfer, and bring social engagement into the crypto world.

Additionally, SRC-20 establishes a binding relationship between a single inscription and the social connection and connection fees. When a social inscription is deployed, the deployer can define the social connection fee. To mint a social inscription, a connection fee must be paid, and it should be directed to an address that has already created a C.Share. Once a social inscription is minted, anyone can mint recursive social inscriptions on its basis in a recursive manner, paying 1/100 of the social connection fee. The "social connection fee" can be understood as a licensing fee for other users to use your content or establish connections with you in the crypto world.

SRC-20 opens up new possibilities for on-chain social interaction. Different creators can contribute various modules, and new creators can innovate on the innovations of their predecessors. This could lead to a surge in various innovations and even the construction of a completely new, autonomous social world.
