Migrating to Segwit: step by step tutorial
When you open your Bitcoin wallet, you are prompted to select
- between Bitcoin and Bitcoin Cash,
and if you select Bitcoin:
- between LEGACY and SEGWIT.
If you click on "I don't know", your legacy Bitcoin wallet will open by default.
HOW TO USE SEGWIT ADDRESSES ?
- If you have a Nano or a HW.1, you need to update to 1.0.3.
- If you have a Nano S, not any update is required.
- Segwit is not available yet for the Blue, but will soon be.
- Launch the Ledger Wallet Bitcoin application
- Connect your device, enter your PIN code
- Open your Bitcoin application on the device itself (only required with a Nano S)
- Disable the "Browser support" setting of this application (only required with a Nano S)
- Select the Bitcoin chain, not Bitcoin Cash*
- Select SEGWIT
- Your Bitcoin wallet opens
- Click on "Receive", a popup opens
- Copy the "Bitcoin address" which is displayed
- Close the "Receive" window
- Click on "Settings" and "blockchains"
- Then you are prompted to the home menu
- Select Bitcoin, not Bitcoin Cash*
- Select LEGACY
- Click on "Send"
- Paste the copied Sewit address on the recipient address field
- Fill in the amount, the fees, and send your transaction
Word of caution to Bitcoin Cash users : NEVER send Bitcoin Cash to a Segwit address generated on the Bitcoin network — you wouldn’t be able to recover your coins.
SEGWIT THIRD PARTY WALLETS
Segwit support for Ledger products is available on:
- GreenAddress (desktop, Android)
- GreenBits (Android).
2. What about Segwit2x
Segwit2x, the second part of the New York Agreement was supposed to go live on block 494,784 (roughly around November 16th 2017) by increasing the block size limit from 1MB to 2MB. It finally won't happen.
