# Fees

### Fee Structure

Anvil API charges the following fees for operations on the Cardano blockchain: These fees are paid by the end-customer and not the developers building on top of the Anvil API.

| Operation                  | Fee      |
| -------------------------- | -------- |
| Transaction                | 0.15 ADA |
| Smart Contract Interaction | 0.15 ADA |
| Minting                    | 1 ADA    |

#### Fee Details

**Processing Fee**

A fee of **0.15 ADA** is charged to the end user for each Anvil API interaction processed. This covers the cost of processing and validating the interaction on the Cardano blockchain.

**Smart Contract Interaction Fee**

A fee of **0.15 ADA** is charged to the end user for each smart contract interaction processed. This includes contract deployment and any other operations that involve interacting with smart contracts on the Cardano blockchain.

**Minting Fee**

A fee of **1 ADA** is charged to the end user for each minting operation. This covers the additional resources required for token creation and metadata management when minting NFTs or fungible tokens.

> **UI/UX Note for Developers**: To ensure a transparent user experience, applications should clearly communicate the total cost of interaction to end users before they approve transactions. This includes explaining that Anvil API fees will appear as charges from an address that is not your application's address.

### Billing and Payment

Fees are automatically calculated and deducted during the respective operations. No additional action is required from your side to process these payments.
