The token code names on this public testnet will be limited to 6 - 12 bytes. Token codes of 4 or 5 characters are not allowed because they are already in use on the mainnet. For brc-20 on Fractal, the token code name can contain letters (uppercase and lowercase: az/AZ), numbers (0-9), and underscores (_). A total of 63 different characters are available. All brc-20 assets on Fractal support fair issuance and self-issuance.
