Are there any fees associated with using smart contracts ?

Yes, there are fees associated with using smart contracts on the Helium blockchain.

The fees are paid in Helium tokens (HNT) and are used to incentivize miners to process transactions. The amount of HNT required for a transaction depends on the complexity of the smart contract and the amount of data being stored or processed. Generally, more complex contracts require more HNT to be paid as a fee.

Additionally, if a contract requires data storage or processing, an additional fee may be charged depending on the size of the data being stored or processed.
