Node proxy

The node proxy works like a normal TRON full node such as TronGrid. Change one URL, and keep the rest of your code:

import { TronWeb } from 'tronweb'

const tronWeb = new TronWeb({ fullHost: 'https://<PROXY_HOST>' })

• Reads (balances, blocks, contract calls) go straight to the TRON network.
• Broadcasts that need energy, such as a USDT transfer, are relayed through Tronergy. We cover energy and bandwidth and broadcast the transaction as signed. You pay from your balance.
• Plain TRX transfers and other bandwidth-only transactions go straight to the network, paid by the sender.

Use the proxy when you cannot easily change how your app broadcasts. Use the REST API when you want full control and status tracking.

Linked walletsCopy Anchor Link

Link the addresses your users send from in the dashboard. You prove you own each one by signing a message with it. Broadcasts from linked addresses are sponsored. Others go to the network as normal.

Node linksCopy Anchor Link

A node link is a private proxy URL. Every energy-using broadcast through it is sponsored, whoever signed it. Use it when you do not know your users' addresses in advance.

const tronWeb = new TronWeb({ fullHost: 'https://<PROXY_HOST>/n/<code>' })

For gRPC, send the code as x-node-link metadata instead. Create links in the dashboard under Developer → Node Connection.

When sponsorship failsCopy Anchor Link

Your broadcast policy decides what happens to a linked wallet's transaction if it cannot be sponsored:

• protect (default): the transaction is not broadcast, but the proxy still answers with success.
• passthrough: it is broadcast unsponsored, and the sender burns their own TRX.
• reject: the proxy returns 403 NON_GASLESS_REJECTED.

Get startedCopy Anchor Link

1. Ask support for early access.
2. Fund your balance.
3. Link your sending wallets, or create a node link.
4. Pick a broadcast policy.
5. Point TronWeb's fullHost at the proxy.

See node proxy API for settings, links, broadcast history and proxy errors.
