# Send Transactions

Send transactions after meeting the prerequisites.

# Prerequisites

  • Wallet: Set up a wallet via Keeper Wallet or WX Network.

    NOTE: Ensure saving your wallet's seed phrase to send transactions.

  • Tokens: Obtain WAVES tokens to cover each transaction's fee:
    • For the Mainnet network: Get at least 0.001 WAVES via Available Market Options.
    • For the Testnet network: Get at least 0.001 WAVES via Faucet.
    • For the Stagenet network: Get at least 0.001 WAVES via Faucet.

# Tutorial

Follow the instructions for the transaction type you want to send:
