Lamden uses stamps to calculate transaction costs. Stamps are equivalent to gas on the Ethereum blockchain.
You need to have TAU on your account to pay for the stamps of each transaction.

AssertionError(‘Not enough coins to send!’,)
This appears when you tried to send tokens that are not in that account, or you tried to send too many which you don’t have. Check to make sure you have enough of that particular token in the account you are sending from.

There seems to be a bug in the webserver that is allowing invalid transactions through, such as those from wallets that do not have enough stamps. This bug does not affect security or performance. If you are seeing the “10 attempt tried” error, wait a few minutes and resubmit your transaction.
Transaction timestamp is too old. Submit again.
This occurs when the client time is out of sync with the server time by too much. A simple syncing of your PC clock is usually all that is needed.

TypeError: Failed to fetch
This one does not occur often, but when it does it has been caused by the permissions for the wallet extension in your browser not allowing functions to be performed. If you are using pop-up blocking software make sure the wallet can operate freely. Similarly if using browsers like Brave, it has been known to cause instability with some dApps (disable ‘Shield’ for the particular dApp website).
