# 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».\

«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.
