To transfer funds out of your account, or in, you need your Public Key, which you can find by hitting Transfer in your wallet, and then the currency you want to transfer. Something that is not at all well explained in crypto is that if you want to accept differing types of currencies, you have to give an address for each one. For example, if you are accepting an NFT that is on the ETH chain or some ETH itself, you need to head to “Receive” in your wallet and then find the ETH address to receive funds.
If you give the wrong address to receive the ETH, say, the BTC address, the transaction will not go through. You will need to give SEPARATE public keys for transfer of BTC, ETH, SOL, and more, as each chain you are buying, like BTC or ETH or Solana, needs its own public key for the transfer. Note that the Public Key is different from your Private Key. This is a long string of letters and numbers (per currency) that can be shared at will. The Private Key, as mentioned before, looks more like a square block and it’s a cluster of words.
