# Sign Transaction

### 🚀  Get Started

Be sure you have [created a crypto wallet](/general/create-a-wallet.md). 

And have **funds** in your wallet to pay for transaction fees. 

> In simple terms, a blockchain fee is a small amount of cryptocurrency that users pay to complete a transaction on the blockchain network. It's a fee that is paid to the network's miners, who confirm and validate the transaction and add it to the blockchain ledger.

### 💳 Fund your wallet

First, choose the blockchain you want to launch your collection. And send some funds to pay for the transaction fees. The fee amount depends on the network you want to deploy on. \
\
Most users first want to deploy on the **TESTNET**.
