On August 19, Fractal Bitcoin posted on the X platform that it has activated the BRC20 module on the Fractal testnet. The BRC20 deployment rules on Fractal are as follows: The length of the token name ranges from 6 to 32 bytes (the 4/5 byte BRC-20 stock code is explicitly prohibited to prevent conflicts with the Bitcoin mainnet). Token names are limited to the "a-z A-Z 0-9 _" byte set, a total of 63 valid character types; All brc-20 tokens on Fractal will have self_mint fields enabled.
