GasFree transfers

Wallet-cli supports GasFree integration — gas-free TRC20 transfers via the GasFree service.

For more details, see the GasFree Documentation and the TronLink User Guide for GasFree.

Prerequisites. You must obtain an API Key and API Secret from GasFree for authentication, and set them in config.conf. See the official application form for how to set up API authentication.
