This guide lists the common problems you might face while using the Firo wallets. If your problem is not listed here, please visit the #support channel on Discord or Telegram.
Firo QT
Breaking masternode collateral
If you wish to stop your masternode and break the 1000 FIRO masternode collateral, you must first enable Coin Control.
-
Settings -> Options -> Wallet -> Enable coin control features
-
Once done, you should be able to see an Input button in the Send tab. Click on Use transparent balance button at the bottom right.
-
Click on Inputs button. Find your 1000 FIRO collateral, right-click and choose Unlock unspent.
The 1000 FIRO should now be available for you to send.
Masternode and mining payouts
If you frequently receive masternode or mining payouts, you might get the “Transaction too large” error message when trying to send FIRO as the transaction can be too big.
In the Transaction tab, you can double-click on the problematic transaction and check the following:
- Status: 0/offline, has not been successfully broadcast yet
- Transaction total size: several hundred bytes
-
To workaround this issue, enable Coin Control in Firo QT by doing Settings -> Options -> Wallet -> Enable coin control features.
-
Once done, you should be able to see an Input button in the Send tab for both private and transparent Sends.
-
Use this Coin Control to combine your input transactions into manageable amounts and send it to yourself to consolidate.
Example: you receive a lot of 0.1 FIRO transactions. Use Coin Control to combine them into 1.0 or 2.0 FIRO before trying to send out a big amount like 100 FIRO.
Example 2: you receive a lot of 3.125 FIRO transactions. Use Coin Control to combine them into 150 FIRO before trying to send out a big amount like 1000 FIRO.
Example 3: you have a lot of small private Spark mints. Use Coin Control to combine them before trying to send out a big amount.
If you frequently encounter this problem, some recommendations are:
- regularly combine these masternode and mining payouts instead of waiting until you want to send them out.
Electrum Firo
Mining payouts and hardware wallets
When using a hardware wallet as the receiving address for mining pools’ payout, the amount of input transactions can overwhelm the hardware limitations of the hardware wallet.
-
In Electrum-Firo, select View -> Show coins.
-
Right-click on only one entry and select Spend, then use the Send tab to send the selected inputs. Your hardware wallet should prompt you almost immediately.
-
If that is successful, try Ctrl + Left Click in the Coins tab to select a maximum of five inputs. Then right-click and select Spend, again using the Send tab to send the FIRO out.
-
You might notice a bit of sluggishness while waiting for the hardware wallet to show the transaction approval prompt.
-
You can try with 10, 15 or 20 inputs. Exceeding 20 inputs is not recommended as it can cause the hardware wallet to time out.
If you frequently encounter this problem, some recommendations are:
- increase the payout threshold of the mining pool if possible. Example: 0.5 FIRO instead of the default 0.1 FIRO;
- do not use an address on the hardware wallet as the receiving address for pool payout;
- regularly combine these mining payouts instead of waiting until you want to send them out.
