According to Odaily, Fractal Bitcoin has announced the activation of the BRC20 module on its Fractal testnet via a post on the X platform. The deployment rules for BRC20 tokens on Fractal are as follows: the token name length must range from 6 to 32 bytes, explicitly prohibiting the use of 4/5 byte BRC-20 token codes to prevent conflicts with the Bitcoin mainnet. Additionally, token names are restricted to the 'a-z A-Z 0-9 _' byte set, totaling 63 valid character types. All BRC-20 tokens on Fractal will also enable the self_mint field.
