Lastly, I would like to recommend a public chain inscription #Fans, which is the only leading inscription on the Fantom chain. The frc20.io marketplace is about to undergo a major update, using Fans inscriptions as the ecological foundation "fuel". This move is a new milestone for public chain inscriptions.
