Wallet Integration

Learn how wallets integrate CatFee Seamless Energy and how to choose the appropriate node and authentication method.

Overview

Any wallet that supports custom TRON nodes can integrate CatFee Seamless Energy.

Simply replace the wallet's TRON node or broadcast node with the dedicated node address provided by CatFee. The wallet continues to construct and sign transactions locally. After receiving a signed transaction, the Seamless Energy node automatically prepares ENERGY or BANDWIDTH as needed, then broadcasts the original transaction to the TRON network.

CatFee does not need your private key or mnemonic phrase and does not modify transaction addresses, amounts, signatures, or contract parameters.

Requirements

• A Seamless Energy node has been created and enabled in the CatFee User Center

• You have obtained the dedicated node address

• The wallet supports a custom TRON node or broadcast node

• You have selected an appropriate authentication method

Choose a node address

Wallets may support different connection methods:

Integration method	Node address	Connection
TokenPocket and other wallets or applications that support HTTP	https://{NodeSlug}.catfee.vip	HTTPS
TronLink mobile app	{NodeSlug}.catfee.pro:50051	Plaintext gRPC

Choose the node according to the connection method supported by the wallet. The HTTPS node and the dedicated plaintext gRPC node for the TronLink mobile app are not interchangeable.

Choose an authentication method

Scenario	Recommended method	Description
TokenPocket, TronLink, and similar consumer wallets	Bound address	The wallet does not need to send an additional request header
Wallets that support custom headers	API KEY	Requests must include CF-NODE-KEY
Temporary testing	No authentication	Not recommended for long-term use

Bound address authentication is recommended for ordinary wallet users. Bind the wallet address that will initiate transactions in the CatFee User Center before configuring the node.

Workflow

1. The wallet constructs and signs the transaction locally.

2. The wallet sends the signed transaction to the Seamless Energy node.

3. The node prepares Energy or Bandwidth according to the transaction's requirements.

4. The node broadcasts the original transaction to the TRON network.

5. The wallet displays the transaction result through its existing flow.
