Public RPC Endpoints
The following public RPC endpoints allow you to connect wallets and applications to the TRON mainnet without running your own node:
- TronGrid (official default):
https://api.trongrid.io/jsonrpc - DRPC:
https://tron.drpc.org - Ankr:
https://rpc.ankr.com/tron_jsonrpc - Alchemy:
https://tron-mainnet.g.alchemy.com/v2/<api-key> - Fastnode:
https://public-trx-mainnet.fastnode.io/
TronGrid is the official RPC maintained by the TRON Foundation and is recommended as the primary endpoint for production use.
Network Resources: Bandwidth and Energy
TRON uses two resource types instead of gas fees:
- Bandwidth – Required for basic TRX and TRC-10 transfers. Each account receives 5,000 free bandwidth points per day.
- Energy – Required for executing smart contracts (TRC-20 transfers). Earned by staking TRX.
If you lack sufficient resources, 0.1 TRX is burned for bandwidth and TRX is burned proportionally for energy.
