ElectrumSV 1.3.0b3-multisig

The splash screen for ElectrumSV 1.3.0b3.

Bug fixes in 1.3.0b3

Non multi-signature polish

While these releases are not intended for people to create new wallets with, some people do, and kindly report the errors they encounter. This has resulted in some fixes to a few things that were a bit further along the roadmap, in order to stop these things from being reported any more! Thanks to our kind users who vigilantly submit bugs through the automated error reporter.

  • The receive tab shows a “No active account” if the wallet has no account, rather than erroring when people play with the UI.
  • The coin-splitting tab shows a “No active account” if the wallet has no account rather than erroring when people select it.

Lowered default transaction fee to 500 satoshis/kB

Users of other wallets are paying 500 satoshis/kB, which is half the old ElectrumSV default fee of 1000 satoshis/kB. These lower fee transactions still get mined, so I think there’s a good argument that ElectrumSV users should be paying that fee too. Read a short article about it.

No custom fee rate means the wallet is paying the default fee rate.

Fixed fee calculation when not paying to an address

When creating a transaction, the change from the spent coins is distributed between a variable range of change outputs. How many change outputs affects the cost of making the transaction in terms of fee, due to the eventual size of the transaction.

Automatic error reporting

The system used to give users the option to report errors they encounter as bugs on Github, was broken in some circumstances. This has been fixed and all such errors are now able to be reported.

Oops, an error has occurred. Please consider reporting it.

Block explorers and address-less payments

Now that the Genesis upgrade has removed the false limit that transactions must be “standard”, there is no guarantee that a payment will be made to an address. WhatsOnChain and satoshi.io have added support for viewing transactions that use specific scripts, which allows these address-less payments to be viewed.

Long-standing errors for proxy users

I don’t use a proxy, but some people do, and they encountered errors going all the way back to ElectrumSV 1.2.1. These errors were related to trying to edit their proxy settings after they had configured and saved those settings already, enabling the use of a proxy. Reported by much appreciated error reporter users.

A networking feature you and I likely never use.

A new REST-based API

The old JSON-RPC API has been removed and replaced with a new asynchronous REST-based API. This provides a much more stable, responsive base for our future APIs. An example application is provided to show people how they can run their own wallet application based on ElectrumSV. Developed by Kiwi AustEcon.

Change and privacy

When making a transaction the selection logic which decides which coins to spend would combine all the available coins into one. This is not ideal from a privacy perspective, and the fix restores the behaviour to how it has historically worked — Fix provided by Kiwi AustEcon.
