Pending Transactions

Pending transaction is a method to implement so that the

Create the data field that should be sent to your smart contract when users wish to perform on-chain operations on their NFTs.

Create the data field

const abi = require('ethereumjs-abi');


// Define the function name and parameters
const functionName = 'mint';
const addressParam = 'address';
const amountParam = 'uint256';


// Define the parameter values
const addressValue = '0x123abc...'; // The address parameter value
const amountValue = 100; // The amount parameter value


// Define the function signature
const functionSignature = abi.methodID(functionName, [addressParam, amountParam]).toString('hex');


// Encode the function parameters
const encodedParams = abi.rawEncode([addressParam, amountParam], [addressValue, amountValue]).toString('hex');


// Combine the function signature and encoded parameters
const encodedFunction = '0x' + functionSignature + encodedParams;


console.log(encodedFunction);

Update the Data field

To ensure that the transaction will be executed the next time the user scans the chip, use the following API:

PUT /nfc-nft/byTag/:nftId

Querystring params:
        authtoken: will provided by Boyo

Body Params:
        pendingTransactionData: state['data'],
        pendingTransactionValue: state['value']

The pendingTransactionData parameter is the function call, including the ABI-encoded parameters, to your smart contract.

The pendingTransactionValue is the value in Wei that users would pay.

Get the Data field

You can read the pending transactions using this request
