### What is the Withdrawal and can I withdraw on the wallet of my choice?

The Withdrawal is the process of transferring your blockchainized cards from your custodial First Oasis wallet to a wallet you own (ie. a wallet you control by knowing the private key). Once a card is blockchainized within the game or when you received your cards trough your [ChainChronicles](https://docs.spellsofgenesis.com/chainchronicles/chainchronicles-phased-out) subscription, it's stored in your First Oasis address. You can then choose to withdraw your card to either an Ethereum or Counterparty address.

### **Do I need BCY or BCYETH based on the chain I choose to withdraw my card on?**

It is not obligatory to use BCY from the specific chain you intend to withdraw your card to. For instance, you can use BCY from Counterparty to facilitate a withdrawal on the Ethereum chain, and vice versa.
