** Ethereum transaction conversion to hex
As a Bitcoin developer, you are probably known for using Bitcind API Sendrawtransaction. However, when working with Ethereum, things can become a little more complicated given the use of gas and transaction coding. In this article, we will study how to convert its Ethereum transactions in Hexadecimal strings before using Sendrawtransaction.
Why is it necessary?
“Sendrawtransaction” API awaits the transaction object in its standard format, but Bitcoin’s natural transaction format (also known as “raw” format) is different from Ethereum’s. Specifically:
* Gas:
Ethereum requires the price of gas and the amount for every transaction that is not in Bitcoin transactions.
* Business Coding: Ethereum uses a more sophisticated encoding scheme to represent transactions than Bitcoin.
* Signatures: Ethereum Signature Scheme (ECDSA) requires additional data other than the standard Bitcoin transaction format.
Solution: Turning Ethereum in Friendly Format
To solve these differences, you will need to turn Ethereum transactions on the format compatible with the API Sendrawtransaction. Here are some steps to take:
- Use
'Ters.js:
* Install the `js' library using NPM or yarn:NPM install ethers.js
* Import and use‘hers.js: Const Transaction = New Ethers.transaction ();
- Format your Ethereum Deal:
JavaScript
Const inputtx = {
from: ‘your_account_address’,
to: ‘Beneficiary_address’,
NONCE: 0,
Gasprice: ‘0x’ + ‘1E + 10’, // Gas Price Example Ethereum Standard
Gaslimit: ‘20000’, // Example of Deal Gas Restriction
// Add your data here, for example, residues and transactions
};
`

Turn into Ethereum’s friendly format:
* Create a new object “etheretransaction” from the entrance “inputtx” object using new ethers.transaction (inputtx);
* The resulting object “Ethers.transaction” will be in the natural format of Ethereum, which is compatible with “Sendrawtransaction” API.
- Send a deal:
`JavaScript
Const tx = a new ether transaction ();
TX.Appendfromaddress (‘Your_Account_address’, 0x1);
TX.Appendtoaddress (‘Recipe_Address’);
tx.setgasprice (“0x” + “1E + 10”); // Set the gas price in the Ethereum standard
Tx.setgaslimit (20000); // Set the gas limit for the transaction
Const Signedtx = Expect Tx.Sign (new ether account ());
Const Transactata = tx.rawtransaction ();
Const hextransaction = transactundata.Tostring (‘hex’); // Convert to the hexadecimal string
// Now you can use API “Sendrawtransaction” with your Ethereum friendly deal
Const reaction = wait (waiting bitcindclient.sendrawtransaction (Hextransaction)). reaction;
`
When performing these steps, you should be able to convert your Ethereum transactions in a format compatible with the API Sendrawtransaction and solve all the problems associated with gas and transaction coding.
