Transfers

Fortress APIs allow you to internally transfer or withdraw crypto. Similar to our payments endpoint, the transfer endpoint makes it easy to move assets based on the to and from fields. If you want to transfer crypto between two custodial accounts, you'll just need to specify the custodialAccountId. If withdrawing crypto, you'll specify the source custodial account and the destination wallet address.
