Frequent transaction errors
To conduct transactions, the wallet must have 0.1 TON for transfers to exchanges or other people and approximately 1.1–1.5 TON (for working with NFTs and tokens) to cover fees. Some transactions take coins with a margin and then return “change". After a successful transaction, spread fees are refunded. Several errors are related to the lack of coins for the fee or operation. The errors are as follows:
Insufficient funds. The error indicates that there are no coins in the wallet to cover the fee for sending NFTs or tokens.
Failed to calculate fee. Your have few coins in your wallet, which is insufficient to cover both the micro transaction and the fee for it.
FAILED in the comment section when making an operation. This error indicates a lack of coins for the transaction. Example: If you bet 500 TON on an NFT but you only have 400 in your account, the Failed error will be displayed in the Comment section.
