SiaPrime Wallet Commands

If you’re comfortable with the command-line, you can interact with SiaPrime in powerful ways. This is a list of all the commands that SiaPrime understands, and a brief description of what they do.

These can be accessed at any time by using spc help.

All commands start with spc and are followed by a flag or a command.

You can also use the Terminal in SiaPrime-UI. When doing so, you can type commands without adding spc.

error when calling /wallet/siacoins: unable to fund transaction: wallet has coins spent in incomplete transactions – not enough remaining coins

If you are trying to send 100% of your wallet balance, you should know that the wallet does have a fee built in so you can’t send 100% of the balance in your wallet – you can try sending smaller amounts.

If that does not solve your problem then: Reinitialize the wallet. Please, before doing this, make sure you have your seed words available.. then Go to the terminal tab in the wallet and type: wallet init-seed –force It will prompt you for your seed words – after it loads, try again to send coins at this point.

If you get a message at this point saying “API authentication failed” then go to the about tab and click on Show SiaPrime Data which on Windows will place you on a path like: C:\Users\username\AppData\Roaming\SiaPrime-UI

At this point, close out of the wallet, including right clicking the icon on the task bar and quitting from there and then you want to rename the SiaPrime-UI folder to SiaPrime-UI-backup then open the wallet again.  The wallet will re-sync and you will need to type in your seed words to open the wallet and should now be able to send coins.


SiaPrime allows for local passwords for a seed to be set. By default the password will be the seed. If a custom password is set, it may not be saved through version updates, so try the seed again.

You may notice the seed and password are (by default) identical; this is expected behavior. SiaPrime allows users to create an easy to remember passphrase distinct from the seed, but the seed is the true password and the only way a user can recover a wallet in the case of corruption of wallet loss or on a different installation.

Wallet Re-Initialize (Force rescan)

Occasionally a transaction pertaining to your wallet can be missed. To force a rescan, open the ‘Terminal’ tab of the UI, and use the command ‘wallet init-seed –force’. Use your seed when asked. The rescan will take some time to complete.

Loading a Seed

On a fresh install: open the ‘Wallet’ tab of the UI and select “Load a wallet from a seed”. Enter your seed for both the seed and password fields. Password can be changed afterward via ‘Change Password’ in the ‘Wallet’ tab, but note this password applies only to this specific installation of SiaPrime (and never touches the blockchain).

On an existing install/wallet already loaded: either recover/sweep the seed (see above FAQ), or force the UI to switch primary wallet to new seed by opening the ‘Terminal’ tab and using the command ‘wallet init-seed –force’. As always, keep backups of seeds.

Recover Seed

Recover Seed “sweeps” or transfers all of the balance of the entered seed in to the wallet currently loaded.

Updating SiaPrime

Close SiaPrime completely. Download the latest wallet. Extract the downloaded files in to a new location, or on top of an existing install (when asked to replace or duplicate the files, click replace all).

Moving the Consensus Database or Internal Data Files

1) Run SiaPrime at least once. This will generate the necessary files.

2) Find the files by clicking ‘Show SiaPrime Data’ in the ‘About’ tab of the SiaPrime-UI.

3) Close SiaPrime completely (see below FAQ).

4) Move the ‘siaprime’ folder from this internal data folder to your desired location (ex. D:\)

5) Edit ‘config.json’ from the root of the internal data folder, and change the ‘datadir’ to the new ‘siaprime’ folder location. Leave the remaining handful of files (including ‘config.json’) in their original location.

Backing Up the Wallet and Important Data

The seed is the only way to protect and access your funds. In addition to writing it down, you can view it by clicking ‘Backup Wallet’ in an unlocked wallet.

The software’s internal data files should be backed up regularly if you are hosting or renting storage. The files can be found by clicking ‘Show SiaPrime Data’ in the ‘About’ tab of the SiaPrime-UI.

Closing SiaPrime-UI

Find SiaPrime from the system tray (bottom right of taskbar on Windows), right click and select ‘Quit SiaPrime’.

If you would prefer SiaPrime to close entirely when closing the main window, edit the ‘config.json’ file from the internal data files and change ‘closeToTray’ to false.
