Bitcoin #1 vs Segwit Wallet


I noticed that when I use the Desktop Suite app on my Mac and plug in my trezor, I now see two accounts. Bitcoin #1 and Segwit, and all of my bitcoin is in the Segwit account. I originally transferred my bitcoin to my Trezor by at, but then downloaded the Desktop suite later. All of my bitcoin is there, so not worried, just wondering if someone can explain this to me?


Bitcoin have three different address types:

  • P2PKH addresses start with the number 1. Example: 1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2.
  • P2SH addresses start with the number 3.
  • Bech32 addresses also known as “bc1 addresses” start with bc1.

The first two are supported by the web wallet, while all three are supported by Trezor Suite. Bech32 is the latest/newest version. Also, the newer versions are backward compatible with the older versions.

So my guess is that you had some Bitcoins in different address formats before and transferred them to Bech32 at some point, if they don’t all show as Bech32 in Trezor Suite now.
