This SDK supports following Read & Write operations:-

XRC20 Token: Read methods	XRC20 Token: Write methods
name(url , token_address)	approve(url , token_address ,privateKey , receiverAddress , owneraddress)
symbol(url , token_address)	transferToken(url , token_address , privateKey , receiverAddress , owneraddress , amount)
decimal(url , token_address)	transferFrom(url , token_address , privateKey , receiverAddress , owneraddress , amount)
totalSupply(url , token_address)	increaseAllowance(url , token_address , privateKey , receiverAddress , owneraddress , value )
balanceOf(url , token_address , owneraddress)	decreaseAllowance(url , token_address , privateKey , receiverAddress , owneraddress , value)
allowance(url , token_address , owneraddress , receiverAddress)	transferXDC(url , privateKey , owneraddress , receiverAddress , send_token_amount)

Environment Variable

Create a .env file in the root directory of the react-native project to put the wallet and endpoint information in like so:

APOTHEM_ADDRESS = wss://ws.apothem.network

Example for XRC20

Read Method

//import read function Name

import Name from 'xdc-sdk-react-native/src/xrc20/name';

const getName = async () => {
  const url = network-url ;
  const token_address = XRC20-token-address;

  const name = await Name(url , token_address);
}

This example returns name of the specified address.

Write Method

//import write function transfer from

import transferFromAmount from 'xdc-sdk-react-native/src/xrc20/transfer_from';

const transferFrom = async () => {
  const url = network-url ;
  const token_address = XRC20-token-address;
  const sender_address = sender-address;
  const receiver_address = receiver-address;
  const privateKey = sender-private-Key;
  const amount = transfered-amount;

  const transfer = await transferFromAmount(url ,token_address ,privateKey ,receiver_address ,sender_address ,amount);
}

This example returns transfer object .
