💡\[Definition] **Transaction fees:**

The blockchain transaction fee is an economic security mechanism designed to prevent malicious actors from flooding the blockchain with irrelevant transactions to saturate the network making legitimate transactions unprocessable. This fee is charged in the platforms' utility token when performing blockchain transactions, and is always deducted from the account starting the transaction itself.

\[Market problem]: **Unpredictable transaction fees**&#x20;

Businesses or average blockchain users can’t calculate the future expenses for transactions on current blockchains. This is a problem for the whole blockchain industry especially for DeFi ecosystems dealing with mass transactions, bridges, DApps uploads, etc.&#x20;

## QANplatform says goodbye to the ever-changing high transaction fees

Everyone is aware of Ethereum's painfully high gas fees. Whether the user would like to buy an NFT, use a DeFi solution, or just buy/sell tokens, the volatile gas fee can be a real financial burden.&#x20;

The solution for this specific problem from QANplatfom is to introduce a pre-defined price range (min and max) for transaction fees. Transaction fees will be fixed to USD. This helps to plan and predict costs no matter if you are an individual or an enterprise.&#x20;

The community will have the chance to change the transaction fee price-range through governed voting.&#x20;
