A TRON node that pays for energy
Swap your TRON node URL for your TEnergy endpoint. Right before a transaction is broadcast, the proxy delegates the energy it needs, so an address with 0 TRX can send USDT.
Your endpoint https://<host>/<node-key>/wallet/*
How it works
-
1
Swap the URL
Point your backend or wallet at the endpoint instead of your usual node. Nothing else changes.
-
2
Sign as usual
You build and sign the transaction yourself; the proxy never holds your keys.
-
3
Energy first
On broadcast the proxy simulates the transaction and delegates only the energy the sender is missing.
-
4
Broadcast unchanged
Your original bytes go to the network unchanged; the delegated energy is reclaimed after the block.
What passes through unchanged
- Every read and every other call under /wallet/*, /walletsolidity/*, /v1/* and /jsonrpc.
- A broadcast whose sender already has enough energy: sent at once, no charge.
- A transaction whose simulation fails: sent at once, unfunded.
Price and caps
- Price per transaction: from 1.30 TRX per 65,000 energy, by time of day (indicative).
- Cap per transaction: 300,000 energy (indicative).
- Cap per node key: 3,000,000 energy per hour (indicative).
- Balance too low: the broadcast is rejected with a clear error, so no TRX is burned.
Not covered
Bandwidth is not funded. A USDT transfer needs about 345 bandwidth points, which the free daily allowance of 600 covers.
