Call a contract

How to perform a contract call
A contract call is the equivalent to launching a blockchain transaction. We've already covered that we can't execute a transaction without the user's approval. Therefore to be able to call a contract we will need to do two things i) define the contract call and ii) ask the user for his approval.
The object that can ask the user his approval is called a Signer, once we've created a Signer object we can use the Signer to perform the contract call.
Function
//Creating the signer
arkaneConnect.createSigner();
​
//Asking the signer to transfer a certain value to a certain destination.
signer.executeContract({
    secretType: '<BLOCKCHAIN>',
    walletId: '<WALLET_ID>',
    to: '<BLOCKCHAIN ADDRESS>',
    value: 0,
    functionName: '<CONTRACT_FUNCTION_NAME>',
    inputs: [
      {type: "address", value: "0x80cbb6c4342948e5be81987dce8251dbedd69138"},
      {type: "uint256", value: "73680000"}
    ]
})
Example
const signer = arkaneConnect.createSigner();
​
signer.executeContract({
    secretType: 'ETHEREUM',
    walletId: '71dec640-4eb8-4321-adb8-b79461573fc4',
    to: '0xf147cA0b981C0CD0955D1323DB9980F4B43e9FED',
    value: 0,
    functionName: 'transfer',
    inputs: [
      {type: "address", value: "0x80cbb6c4342948e5be81987dce8251dbedd69138"},
      {type: "uint256", value: "73680000"}
    ]
})
Returns
{
    result: {
        transactionHash: "0xe18975940be795f178b2a0bc553a0d40e0ad6ceb72ee5f62ac53f0a816b4460f"
    }
    status: "SUCCESS"
}
