wallet/getchainparameters - Get TRON Chain Para...
Get current TRON blockchain parameters including fees, voting settings, and resource costs via Dwellir's optimized RPC endpoint.
TRON RPC endpoint: endpoint URLs, plans and pricing.
Get current blockchain parameters including fees, voting settings, and resource configurations. This endpoint returns the governance-controlled parameters that define TRON's fee structure, resource limits, and feature flags.
Overview
TRON's chain parameters are set through Super Representative voting and governance proposals. They control critical aspects of the network including energy prices, bandwidth allocation, account creation fees, and TVM feature enablement. Applications that interact with TRON should query these parameters to calculate accurate transaction costs and verify network capabilities.
Fee planning for payment integrators
If you are building a payment system on TRON (especially for USDT TRC-20 transfers), the getEnergyFee and getTransactionFee parameters are essential for accurate cost estimation. Combine this with wallet/estimateenergy for precise per-transaction fee forecasting.
