Like-type change outputs

When a bitcoin transaction is created, the bitcoin wallet searches for available unspent outputs in the wallet and uses them to send the specified amount to the specified destination. 

The entire unspent output must be spent, so if the amount on the output is larger than the specified amount to send, the remainder is returned to your wallet, in an output referred to as "change".

By default, Samourai Wallet will either create segwit enabled or standard change outputs depending on the type of address that is being sent to. For example, if you are sending to a segwit enabled address, the change output returned to your wallet will also be segwit enabled. Conversely, if you're sending to a standard bitcoin address, the change output will be a standard address. 

Privacy benefit

Like-type change outputs are a privacy feature designed to obfuscate the change output and the destination output when viewed on the blockchain. 

Disable like-type change outputs

Users who prefer to keep all change outputs segwit enabled can disable like-type change outputs in the settings.

  1. Tap the three vertical dots on the top right of the toolbar and then tap Settings.
  2. Tap the Transactions option.
  3. Tap the Receive change to like-typed outputs option.
