Now that we are connected to MEVBlocker, we can send MEV protected transactions.

Sending transactions works exactly like with any other RPC, using the eth_sendRawTransaction method. Since we are using the injected provider here, we are going to use signer.sendTransaction which will create a signature request using your browser's Web3 provider.

Craft the transaction

For demonstration purposes we are simply going to send 0.01 ETH to ourselves. For this, we need to craft the transaction object containing our address as to and 0.01ETH as value:

run.ts
const tx = {
	to: await signer.getAddress(),
	value: utils.parseEther('0.01')
};

Send the transaction

To request signature and submission of the transaction object through your injected web3 provider simply call

run.ts
const transactionResponse = await signer.sendTransaction(tx);

You can access and log the pending transaction hash (open the Developer Console to see the logs) via transactionResponse.hash.

Wait for the transaction to be included

It may take a few seconds for the transaction to be confirmed. We can await the response object and once included return the transactions hash

run.ts
await transactionResponse.wait();
return transactionResponse.hash;

To view your transaction you can either load it via the MEV Blocker status endpoint (https://rpc.mevblocker.io/tx/<tx_hash>) or once mined on Etherscan (https://etherscan.io/tx/<tx_hash>)
