Other Function Calls

• Get wallet address configured for exchange object
  Same usage as Ethereum.

• Switch blockchain RPC node
  Same usage as Ethereum.

• Calculate hash value

  
              javascript
              
              
  let algo = "sign"                   // algo: algorithm/method to use
  let inputFormat = "string"          // inputFormat: input format
  let outputFormat = "hex"            // outputFormat: output format
  let data = "txHash"                 // txHash: specific hash value
  let signature = exchange.IO("hash", algo, inputFormat, outputFormat, data)  // returns signature data
  

  When the algo parameter is set to "sign", it is used for calculating signatures; when set to other algorithm parameters (e.g., "sha256"), the function is equivalent to the Encode() function.
