const tronLink = window.bitkeep.tronLink;
const tronWeb = window.bitkeep.tronWeb;

setAddress

Sets the default wallet address to be used (for sending transactions, checking balances, signing messages, etc.).

This does not set the private key — it only sets the default “from” address.
If you call methods like tronWeb.trx.sendTransaction() without explicitly specifying an address, this default one will be used.
Commonly used alongside a private key or a wallet like TronLink.

        
         
        
tronWeb.setAddress('TXXXXXXX...');

setNode

Dynamically sets or replaces the current node configuration — for example, switching between FullNode, SolidityNode, or EventServer URLs.

Usually, setting just the fullNode is enough — TronWeb will use the same URL for other nodes if not explicitly defined.
Especially useful when connecting to a private chain or custom node.

        
         
        
// Set FullNode
tronWeb.setNode('fullNode', 'https://api.trongrid.io');
 
// Set SolidityNode
tronWeb.setNode('solidityNode', 'https://api.trongrid.io');
 
// Set EventServer
tronWeb.setNode('eventServer', 'https://api.trongrid.io');
