On TRON, each account receives a fixed amount of free Bandwidth every day, which can be used to cover basic transaction needs.

When sufficient resources are available, transactions consume only Bandwidth and Energy and require little to no TRX. For example, when sending ERC-20 tokens on Ethereum, users must pay on-chain transaction fees in ETH. On traditional blockchain networks, transactions typically require paying fees in the native token.
