# Blockchainization What is Blockchainization? Blockchainization is an exclusive feature in Spells of Genesis that enables you to convert your in-game cards into independent and tradeable blockchain assets. However, only cards upgraded to their maximum evolution can undergo blockchainization. When you blockchainize a card, you have the freedom to select the blockchain on which you’d like to receive your card. This flexibility is made possible through the use of «First Oasis».\ \ What is First Oasis? «First Oasis» is our Klaytn-based wallet that acts as a bridge between different blockchains and the game. Klaytn is a public blockchain developed by the Korean company Kakao. When you blockchainize a card, it’s initially moved to First Oasis. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
