Finally, send this hexadecimal data as the transaction's data.
Here is an example JavaScript code:
// Transfer dataconsttransfer= { p:'asc-20', op:'transfer', tick:'avav', amt:'69696969'};// Add the prefixconstasc20Data='data:,'+JSON.stringify(transfer);// Convert to hexadecimalconstuint8Array=newTextEncoder().encode(asc20Data);consthexData=Array.from(uint8Array).map(byte =>byte.toString(16)).join('');// Example code for sending a transactionconsttransaction= { from:'sender_address',// Replace with the actual sender address to:'recipient_address',// Replace with the actual recipient address value:0, gas:'gas_amount',// Replace with the actual gas amount gasPrice:'gas_price',// Replace with the actual gas price data:'0x'+ hexData // Add hexadecimal data as the transaction's data};// Transaction sending logic, this is just an example, actual implementation may depend on the blockchain library or tool used
web3.eth.sendTransaction(transaction, (error, hash) => {if (!error) {console.log('Transaction hash:', hash); } else {console.error('Transaction error:', error); }});
