Sometimes Energy Consumed in tron transactions became half!
In this moment, its345 Bandwidth and 29,631 Energy
But sometimes it became 345 Bandwidth and 14,815 Energy
How to estimate transfer Gas fee in moment?
(If getChainParameters api helping, tell me how? because I don't understand how to use it to estimate fee)
You can use the following tron API to estimate fee: https://developers.tron.network/reference/triggerconstantcontract
For estimating energy: use triggerconstantcontract to call the non-readonly method of the contract, and the energy_used field in the returned value is the energy consumption. Therefore, the fee_limit of the transaction can be set to energy_used x energy unit price
