Tron JSON-RPC Methods

These are the methods that wallets should implement to handle Tron transactions and messages via WalletConnect.

Network / Chain Information

CAIP-2	Chain ID	Name	RPC Endpoint	Namespace
tron:0x2b6653dc	0x2b6653dc	Tron Mainnet	https://api.trongrid.io	tron
tron:0xcd8690dc	0xcd8690dc	Tron Shasta	https://api.shasta.trongrid.io	tron
tron:0x94a9059e	0x94a9059e	Tron Nile	https://nile.trongrid.io	tron

Session Properties

To enable the new simplified transaction structure, wallets should include tron_method_version: "v1" in their sessionProperties during the connection handshake:

{
  "sessionProperties": {
    "tron_method_version": "v1"
  }
}

When tron_method_version is set to "v1", the transaction structure is simplified to remove the nested transaction.transaction format. If not set, the legacy nested format is used for backward compatibility.

tron_signTransaction

Sign a Tron transaction without executing it.

Parameters

• The transaction to sign:
  • address (string) - The sender’s Tron address
  • transaction (object) - The transaction object to sign

Returns

• The signed transaction:
  • txID (string) - The transaction ID (deterministically derived from raw transaction)
  • signature (array) - Array of signature strings
  • raw_data (object) - The raw transaction data
  • raw_data_hex (string) - The hex-encoded raw transaction data
  • visible (boolean) - Whether addresses are in visible format

Example (New Format with tron_method_version: “v1”)

tron_signMessage

Sign a personal message.

Parameters

The message to sign:

• message (string) - The message to sign (plain text)
• address (string) - The account address to sign with

Returns

The signed message:

• signature (string) - The signature string

Example

• Request:

{
  "request": {
    "method": "tron_signMessage",
    "params": {
      "address": "TXUEmLr...",
      "message": "This is a message to be signed for Tron"
    },
    "expiryTimestamp": 1758269816
  },
  "chainId": "tron:0xcd8690dc"
}

• dApp result (what client.request(…) resolves to):

{ "signature": "0x1ec623ee6e4716f5a116d0a2755b158ac05dfbc3e9118cca..." }

The methods below are not part of the required wallet surface in the Reown official Tron Wallet example. dApps may perform these directly against a Tron node or gateway. Wallets may implement them for convenience, but they’re not required.

tron_sendTransaction (optional)

Broadcast a signed transaction to the Tron network.

Parameters

The signed transaction object:

• txID (string) - The transaction ID
• signature (array) - Array of signature strings
• raw_data (object) - The raw transaction data
• raw_data_hex (string) - The hex-encoded raw transaction data

Returns

The transaction result:

• result (boolean) - Whether the transaction was successfully broadcast
• txid (string) - The transaction ID that can be used to look up the transaction

Example

• Request:

  },
  "id": 1
}

tron_getBalance (optional)
