# What are blockchain transaction fees? Features of TON and TRON

## :fearful: Why Do I Need to Pay Transaction Fees?

**Transaction fees** (or **gas fees**) ensure the security of the blockchain and incentivize validators by compensating them for supporting the network. The fee amount depends on the network's load and features.

Fees are calculated automatically when you initiate a transaction. Here's how it works:

### Transaction Fees in TON

* **Sending Tokens**\
  \~0.1 TON.
* **Swaps**\
  \~0.3 TON.
* **Sending NFT**\
  \~0.1 TON.
* **Smart Contract Interactions**\
  Varies based on complexity

### :thinking: How Are Fees Calculated?

**`TransactionFee`**` `` ``= StorageFees + InFwdFees + ComputationFees + ActionFees + OutFwdFees `

* **StorageFees**\
  The fee for storing a smart contract.
* **InFwdFees**\
  The fee for incoming messages.
* **ComputationFees**\
  The fee for executing code in the TON Virtual Machine (TVM).
* **ActionFees**\
  The fee for actions within the code.
* **OutFwdFees**\
  The fee for outgoing messages.

### Transaction Fees in TRON

* **Sending Tokens**\
  From 0.01 TRX.
* **Smart Contract Interactions**\
  Based on energy and bandwidth usage.
* **Account Creation**\
  One-time fee for new accounts.

{% hint style="info" %}
Transaction fees are dynamic and may vary based on network conditions. **MyTonWallet** automatically calculates the optimal fee for your transactions.
