Here you can find an overview of some bugs, which often occur and possible solution for it.

Some users are facing the error message Insufficient funds after they made some changes like
- Swap Coins in the DEX
- Add or remove Liquidity
- Sending DFI or token to another address
One example is shown on the right side
Reason for the Error
The main reason for this error is not having enough DFI coins (UTXOs) to pay the Fees of the Blockchain in your wallet.
Unknowing users could mean, that they have enough, because the DFI-wallet in the App shows a high enough amount. But this number is a mixture of coins and tokens. You get Token from the DEX and Liquidity-Mining, but you need Coins to transfer them to an Exchange or pay for fees.
So, the first thing is checking the available coin amount in your wallet. Go to the console and execute the command getbalance
If your wallet shows less than 0.01DFI, then you don't have enough DFI in your wallet to do anything on the DefiChain. The only way to solve this is sending DFI from outside your wallet to one of the included addresses.
The error message Node is disconnected is shown while the wallet is synchronizing. Most of the time the wallet is already synchronized up to ~90%-95% when the error occurd.
Reason for the Error
There are different reasons which can lead to this error. You can distinguish between the following different types:
- Wallet synchronized normally up to 80%-99% until the error message is shown: That's the most common type, which is a RAM problem. In this case the wallet needs to much RAM to synchronize.
- Wallet does not synchronize and the error message occurd with 0.00% synchronization: Probably a network error
Solution to solve the different reasons for this error message:
- There are two different solutions for the first type:
- Activate the "ReIndex after saving" option in settings to restart the synchronization and activate the button "Delete peers and blocks" to clean the old block files.
- Start the wallet; wait until the wallet is synchronized up to ~90%-95% and shut the wallet down normally (the error message must not occur up to this moment); after that you can restart your wallet (repeat the steps until the wallet is synchronized. You can check the RAM usage of your PC to know the perfect time to shut the wallet down again)
- For second problem type you can try the following solutions:
- Check your firewall settings
- Check your network settings (connect with a private networt instead of a public network)
- Check your Antivir program
App stuck when starting
Your app might be stuck in an endless loop when you want to launch it. Trying to launch it via the console might display request failed with status code 500. Sometimes, you might also get an unable to start blockchain error upon launching the app.
Reason for the Error
Most likely it is a memory (RAM and/or disk space) issue.
Here are a couple of steps that might help:
- Quit the app
- Close unneeded open programs
- Open a system monitor program (Task Manager, Activity Monitor), keep monitoring your RAM utilization
- Make sure you have enough disk space available (more than your RAM size), free up enough so that the app can create a swap file if it runs out of RAM
- Disable and enable your network connection, possibly use another one temporarily
- Try again
If that does not help, try launching the app with the -reindex parameter from the command line.
Still not working? Here are some more experimental steps:
- Create a backup of your wallet.dat file (MacOS: ~/Library/ApplicationSupport/defi/wallets), preferably of the whole defi folder to another drive
- Remove all .dat files in the blocks folder (MacOS: ~/Library/ApplicationSupport/defi/blocks). Try again.
- Downgrade to the last version that worked for you here. Try again.
- Delete all wallet data from the defi folder, start the app again, then quit it. Now the folder structure should have been created again. Copy over wallet.dat from your backup and launch the app again.
Everyting failed so far? Let's start from scratch. You'll need for mnemonic seed for this.
- Delete app data (section above), uninstall defi-app entirely.
- Reinstall a version you think might work (either an older specific one or the latest)
- Launch the app
- Recreate the wallet from mnemonic seed.
