+Web3Js Plugin for Blob Transactions (EIP4844)
 ===========
 
+This Web3Js plugin enhances the capabilities of Ethereum transactions by adding support for EIP4844 transactions, also known as "Blob transactions". EIP4844 introduces a new transaction format that allows for more efficient data storage and transmission on the Ethereum blockchain.
+
+## Installation
+```bash
+npm i web3-plugin-blob-tx
+```
+
+## Usage
+
+### Register plugin
+```typescript
+import {Web3BlobTxPlugin} from 'web3-plugin-blob-tx';
+web3 = new Web3(/* provider here */);
+web3.registerPlugin(new Web3BlobTxPlugin());
+web3.defaultHardfork = 'cancun'; // set hardfork which support blob transactions
+web3.defaultChain = 'sepolia'; // set chain which support blob transactions
+```
+
+### Methods
+
+#### sendTransaction
+```typescript
+// add account to sign transaction
+const acc = web3.eth.accounts.privateKeyToAccount(String(process.env.PRIVATE_KEY));
+web3.eth.accounts.wallet.add(acc);
+
+const txData = {
+	from: acc.address,
+	nonce: await web3.eth.getTransactionCount(acc.address),
+	to: '0x7ed0e85b8e1e925600b4373e6d108f34ab38a401',
+	maxFeePerBlobGas: 31458962313,
+	gasLimit: 5000000,
+	maxFeePerGas: 31458962313,
+	maxPriorityFeePerGas: 31458962313,
+	blobsData: ['any data text'],
+};
+// you can get transaction receipt
+const transactionReceipt = await web3.blobTx.sendTransaction(txData);
+
+// or supribe to events
+const res = web3.blobTx.sendTransaction(txData);
+res.on('sending', data => {
+	console.log('sending', data);
+});
+
+res.on('sent', data => {
+	console.log('sent', data);
+});
+
+res.on('receipt', receipt => {
+	console.log('receipt', receipt);
+});
+
+res.on('transactionHash', hash => {
+	console.log('hash', hash);
+});
+
+res.on('error', error => {
+	console.log('error', error);
+});
+
+res.on('confirmation', data => {
+	console.log('confirmation', data);
+});
+
+const receipt = await res; // and get receipt here
+
+```
+
+#### estimateGas
+```typescript
+import {BlobTransaction} from 'web3-plugin-blob-tx';
+
+const txData:Partial<BlobTransaction> = {
+    from: '0x7ed0e85b8e1e925600b4373e6d108f34ab38a401',
+    to: '0x7ed0e85b8e1e925600b4373e6d108f34ab38a401',
+    value: '0x0',
+    gasLimit: 5000000,
+    maxPriorityFeePerGas: 22380075395,
+    maxFeePerGas: 22380075395,
+    maxFeePerBlobGas: 29458962313n,
+    blobsData: ['any data text'],
+};
+const gas = await web3.blobTx.estimateGas(txData);
+```
+
+#### getTransactionReceipt
+```typescript
+const receipt = await web3.blobTx.getTransactionReceipt(/* transaction hash */);
+```
+
+#### getTransaction
+```typescript
+const transaction = await web3.blobTx.getTransaction(/* transaction hash */);
+```
+
+#### getTransactionFromBlock
+```typescript
+const transaction = await web3.blobTx.getTransactionFromBlock(/* block number or tag */, /* transaction index */);
+```
