Depending on the type of asset you are sending, whether it is Bitcoin or Ethereum, you always send to the receiving wallet's public key or wallet address


Ethereum addresses are long strings of letters and numbers starting with a “0x”. Here’s an example: 0xe79c3300773E8593fb332487E1EfdD8729b87445. 


Bitcoin addresses always start with a “1” or “3”. Here’s a Bitcoin address example: 1BoatSLRHtKNngkdXEeobR76b53LETtpyT


Note: When sending crypto from your SpankPay account to a third party crypto wallet always remember to check if you are sending Bitcoin or Ethereum. Remember, you can not send Ethereum or ERC20 tokens to a bitcoin address or vice versa.
