Staking trx for enegy?

I am wondering how can i stake my trx using trustwallet for energy? I just read how the tron network works and to process trc20 transactions without fee, i need energy aside from bandwidth. but when staking tron to trust wallet, i can’t see the option to stake for energy.

Hello @Vaxirih
Bandwidth allows users to perform Tron transactions, and energy allows users to process Tron smart contracts. Instead of paying gas fees (small amounts of cryptocurrency, such as in Ethereum’s network where gas = small amounts of ETH) to perform these tasks, users stake TRX tokens in their wallet, which generates bandwidth and energy.

@Tobi, i stake but i only get the bandwith not the energy, how can i stake to get the energy?
