Provisional in-wallet help
The Send tab is used to construct outgoing payments. The wallet owner can opt to leave choosing what coins to spend to the wallet to select, or can manually select the ones to use from the Coins tab using the Spend menu option.
The From field is only visible if the wallet owner has selected coins from the Coins tab, and used the Spend menu option to manually designate that the payment should only use those coins. If the user has not manually designated the spending of specific coins, then the wallet will choose from all the coins as needed to cover the amount being spent.
The wallet owner is required to provide a destination for the payment. There are several different types of destination that can be provided:
If provided by the wallet owner, the description is recorded against the transaction and is shown on the History tab (public transaction) or Transactions tab (non-public transaction), depending on whether the transaction is public yet.
One way to ensure that all the coins in the current account are not also linked to the Bitcoin Cash blockchain, is to spend them in a way that is only compatible with the Bitcoin SV blockchain.
The simplest way to do this is to:
This setting is not available for hardware wallets. The existing hardware wallets that are supported by ElectrumSV are made in such a way that they can only sign a very limited range of transaction types. They are unable to sign correctly formed transaction data, like those used by ElectrumSV to make transactions only compatible with the Bitcoin SV blockchain.
If this setting is visible and enabled, any payments made will be made with a transaction that includes an extra data carrier output. This data carrier output is constructed with OP_FALSE OP_RETURN and by including it, the transaction will be considered "non-standard" and will be rejected by any Bitcoin Cash nodes it is sent to. It is possible that a malicious Bitcoin Cash miner could choose to bypass the rules that would otherwise cause this transaction to be rejected, but it is very unlikely that they will choose to and it would have negative repercussions for the Bitcoin Cash blockchain.
This setting can be made visible or hidden from the Wallet tab of the Preferences window, where a setting for that purpose is present.
