Ethereum: web3.js wrong EIP-1559 transaction

Step 1: Review EIP-1559

EIP-1559 is a gas price manipulation standard that was introduced in Ethereum 2.0. It allows users to set their own base gas prices and adjust the gas price at the block level using special tokens called “base amounts”. However, when it comes to signing transactions using web3.js, there is no built-in support for EIP-1559.

Step 2: Sign the transaction manually

To manually sign a transaction, you need to use the “eth_sign” function from web3. You can create a new account and use the “createTransaction” method from the web3 library. Then, call the “sign” method on the transaction object to sign it.

Step 3: Get the signature

To get the signature of a transaction, you need to pass the transaction object to the function “eth_sign” along with an EIP-1559 token that specifies the base gas price and the amount of that token used in the transaction. Here is an example:

const web3 = require('web3');

const address = '0x1234567890abcdef';

// Create a new account

const accounts = [];

const provider = new web3.providers.HttpProvider("

async function main() {

// Get the current account balance

const tx = await provider.getTransactionReceipt({

TransactionHash: await provider.getTransaction('0x1234567890abcdef').txHash,

});

console.log(tx);

}

// Sign a new transaction

const signedTx = await web3.eth.sign(

{

from: '0x1234567890abcdef',

to:

value: '0x1',

},

{

gasPrice: 100000, // Set the base gas price

baseGasPrice: 50000, // Set the base gas price amount used in the transaction

}

);

Step 4: Create a signed transaction and sign it manually

After creating a new account using the `sign'' method, you can use that address to create a new transaction. To do this, call theeth_transactionSign'' function fromweb3''. This will return a signed transaction object.

Step 5: Sign a hex message using web3.js

To manually sign a hex message using web3.js, you must first convert the hex message to a base64 encoded string. Here is an example:

const hexMessage = '0x1234567890abcdef';

const base64Message = Buffer.from(hexMessage).toString('base64');

console.log(base64Message);

Step 6: Create a signed transaction and sign it manually

To create a new transaction, call web3.eth_transactionSign with the account address and base gas price. The function will return a signed transaction object.

Step 7: Create a signed transaction

Create a new transaction using web3.js:

const transaction = {

from: '0x1234567890abcdef',

to: '0x1234567890abcdef', // your address

value: 10, // amount of gas used in the transaction

};

Step 8: Sign the hex message and get the signature

Sign the hex message:

const base64Message = Buffer.from(hexMessage).toString('base64');

const signature = web3.eth.sign(base64Message, { from });

console.log(signature);

The 'signature' will be in the format of an unsigned byte object.

Step 9: Sign the transaction with the received signature

After receiving the signed message or a byte array representing the signature, sign a new transaction using web3.js. Here is an example:

const tx = {

from: '0x1234567890abcdef',

to:

value: 10,

};

tx.signature = Buffer.from(signature);

Step 10: Sign the transaction with the received signature and get the signed transaction

Sign a new transaction using web3.js:

“ javascript

const provider = new web3.providers.HttpProvider(“

async function main() {

const tx = await provider.eth.
