Deploying a TRC-20 token involves writing a Solidity contract conforming to the TRC-20 interface, which defines essential functions such as transfer, approve, and transferFrom. Using development frameworks like TronBox or Tron IDE, compile the contract and deploy it to the Tron network via TronLink wallet, ensuring sufficient TRX for transaction fees. After deployment, the token becomes accessible on the network and compatible with wallets and dApps supporting TRC-20 tokens.
