I checked the new Coinbase wallet address on block explorer and it has zero transactions showing. I tried going through this transfer process again with no luck. I even deleted the Coinbase wallet app and re-downloaded it and still same issue, nothing transfers over. You can see when opening Bread that the coins are still there.
It's possible that coinbase is generating the address on a different derivation path.
Do you remember the character your address start with on Breadwallet? If so, is that same as the first character of the address generated by coinbase?
If you don't access your address anymore, you may be able to find that somewhere else. For example, in your withdrawals history if you have purchased the coins on an exchange.
So at this point I could just use another wallet like electrum and just type in my recovery seed?
As I said in my previous post, you can import your wallet into any wallet supporting BIP39 seed phrases.
If you are trying to access your bitcoin, electrum should work. If you are trying to access your altcoins, you should use other wallets.
I will of course need more than just my recovery seed, such as my wallet address correct? If I can’t access my bread wallet address on the app anymore, how do I go about doing this? Or what else do I need to do?
No, you don't need your address. All your addresses can be derived from your seed phrase.
In electrum, select "Standard wallet" and then "I already have a seed". Click on "options", check "BIP39 seed" and click on "OK". Enter you seed phrase and click on "Next".
After that you need to specify the script type.
If you don't remember the character your bitcoin address start with, click on "Detect existing accounts".
If you remember the character your bitcoin address start with, you can select the script type, manually.
Select "Legacy" if your address(es) start with 1.
Select "p2sh-segwit" if your address(es) start with 3.
Select "native segwit" if your address(es) start with bc1.
Again, you can use electrum only for recovering your bitcoin. If you have any altcoin, you can't use electrum for them. But there are still many alternatives and you don't have to use coinbase.
Could I recover these coins via trezor, Coinomi, blockchain app, or perhaps an exchange such as Binance US, Gemini, or Kraken?
Wallets like Coinomi and blockchain (and many others) and your hardware wallet should work. But you can't use exchanges.
