Kaidro, an anime-inspired role-playing game, has gained popularity on the Ethereum scaling network Ronin. The game's recent premium mint on Ronin sold out in just 10 seconds, generating $2 million in revenue and making Kaidro the third most-traded collection on the Mavis Market. After initially planning to launch on Immutable X, Kaidro switched to Ronin and formed a partnership with Sky Mavis, the creator of Ronin and Axie Infinity.
