I have a Legacy Wallet by Electrum and want a Segwit Wallet to run on my computer,
Can I have both? How do I add a Segwit Wallet to my device?
You can create a wallet file that store different addresses and in different types for you as BlackHatCoiner said.
Alternative
- With a same seed, you can create two types of addresses in Electrum: Legacy and Segwit. You can choose Legacy for your first wallet file (you can name the file as Legacy) and the second file as Segwit (name it as Segwit).
- If you import a seed from wallet with BIP39, you will be able to create three types of wallets: Legacy, Segwit, native Segwit (with addresses start with 1, 3 and bc1). You one of three types and make a name for your wallet file. With same BIP39 seed, you will have 3 wallets if you want.
There are currently three invoice address formats in use:
P2PKH which begin with the number 1, eg: 1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2.
P2SH type starting with the number 3, eg: 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy.
Bech32 type starting with bc1, eg: bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq.
