# Ethereum Gateway

Cloudflare's Ethereum Gateway gives you read and write access to the [Ethereum network](/web3/ethereum-gateway/concepts/ethereum/) without installing any software on your computer.

In particular, users can read all information that has been agreed upon by the consensus of existing nodes in the network. In addition, they can write their own transactions and smart contracts to be stored by these nodes in a distributed manner. Anyone else on the network will be able to view these transactions, and even run your smart contracts using their own supply of the Ethereum currency.

These interactions take place through the official [Ethereum JSON-RPC API](https://github.com/ethereum/execution-apis) and use [Cloudflare-supported API methods](/web3/ethereum-gateway/reference/supported-api-methods/).

# Legacy gateway migration

As announced in [our blog post](https://blog.cloudflare.com/ea-web3-gateways/), Cloudflare is deprecating legacy hostnames that point to our public gateway endpoints at `cloudflare-eth.com` and `cloudflare-ipfs.com`.

If you created a hostname pointing to these gateways during the [private beta](https://blog.cloudflare.com/announcing-web3-gateways/), you should migrate to use our new Web3 gateways to avoid a disruption in service.

---

## Migration guide

The migration is a simple process.

First, create a [Cloudflare account](/learning-paths/get-started/#account-setup).

Then create a new [Web3 custom gateway](/web3/how-to/manage-gateways/#create-a-gateway) with your existing hostname.

Alternatively, you could also create a [Web3 custom gateway](/web3/how-to/manage-gateways/#create-a-gateway) for a new hostname and then modify your application to use your newly created hostname ([IPFS](/web3/how-to/use-ipfs-gateway/) or [Ethereum](/web3/how-to/use-ethereum-gateway/)).

# How the gateways work

When you [create a gateway](/web3/how-to/manage-gateways/#create-a-gateway), Cloudflare automatically creates and adds specific [DNS records](/web3/reference/gateway-dns-records/) to your Cloudflare account.

When the hostname associated with your gateway receives requests, its DNS records route these requests to a Cloudflare Workers script.

![Cloudflare's Web3 gateways provide HTTP-accessible interfaces to the IPFS and Ethereum networks. For more details, continue reading.](/web3/static/web3-gateway-flow-diagram.png)

## Read operations

If the API call to the Worker is a read operation and the requested content is cached, the Workers script will respond with the requested information via HTTP to the client. 

If the requested content is not cached, it will first be requested via API call to Cloudflare IPFS or Ethereum nodes, cached at the edge for future requests, and returned via HTTP response to the client.

## Write operations

*Only available for gateways to EVM-based chains, such as [Ethereum](/web3/how-to/use-ethereum-gateway) and [Polygon](/web3/how-to/use-polygon-gateway).*

If the API call to the gateway is a write operation, the gateway will make an API call to one of the Cloudflare nodes, and the transaction is placed in the local mempool and propagated to peers.

QUESTION: What did the president say about Michael Jackson?
=========
Content: Madam Speaker, Madam Vice President, our First Lady and Second Gentleman. Members of Congress and the Cabinet. Justices of the Supreme Court. My fellow Americans.  

Last year COVID-19 kept us apart. This year we are finally together again. 

Tonight, we meet as Democrats Republicans and Independents. But most importantly as Americans. 

With a duty to one another to the American people to the Constitution. 

And with an unwavering resolve that freedom will always triumph over tyranny. 

Six days ago, Russia’s Vladimir Putin sought to shake the foundations of the free world thinking he could make it bend to his menacing ways. But he badly miscalculated. 

He thought he could roll into Ukraine and the world would roll over. Instead he met a wall of strength he never imagined. 

He met the Ukrainian people. 

From President Zelenskyy to every Ukrainian, their fearlessness, their courage, their determination, inspires the world. 

Groups of citizens blocking tanks with their bodies. Everyone from students to retirees teachers turned soldiers defending their homeland.

Content: And we won’t stop. 

We have lost so much to COVID-19. Time with one another. And worst of all, so much loss of life. 

Let’s use this moment to reset. Let’s stop looking at COVID-19 as a partisan dividing line and see it for what it is: A God-awful disease.  

Let’s stop seeing each other as enemies, and start seeing each other for who we really are: Fellow Americans.  

We can’t change how divided we’ve been. But we can change how we move forward—on COVID-19 and other issues we must face together. 

I recently visited the New York City Police Department days after the funerals of Officer Wilbert Mora and his partner, Officer Jason Rivera. 

They were responding to a 9-1-1 call when a man shot and killed them with a stolen gun. 

Officer Mora was 27 years old. 

Officer Rivera was 22. 

Both Dominican Americans who’d grown up on the same streets they later chose to patrol as police officers. 

I spoke with their families and told them that we are forever in debt for their sacrifice, and we will carry on their mission to restore the trust and safety every community deserves.

Content: And a proud Ukrainian people, who have known 30 years  of independence, have repeatedly shown that they will not tolerate anyone who tries to take their country backwards.  

To all Americans, I will be honest with you, as I’ve always promised. A Russian dictator, invading a foreign country, has costs around the world. 

And I’m taking robust action to make sure the pain of our sanctions  is targeted at Russia’s economy. And I will use every tool at our disposal to protect American businesses and consumers. 

Tonight, I can announce that the United States has worked with 30 other countries to release 60 Million barrels of oil from reserves around the world.  

America will lead that effort, releasing 30 Million barrels from our own Strategic Petroleum Reserve. And we stand ready to do more if necessary, unified with our allies.  

These steps will help blunt gas prices here at home. And I know the news about what’s happening can seem alarming. 

But I want you to know that we are going to be okay.
Source: 5-pl
Content: More support for patients and families. 

To get there, I call on Congress to fund ARPA-H, the Advanced Research Projects Agency for Health. 

It’s based on DARPA—the Defense Department project that led to the Internet, GPS, and so much more.  

ARPA-H will have a singular purpose—to drive breakthroughs in cancer, Alzheimer’s, diabetes, and more. 

A unity agenda for the nation. 

We can do this. 

My fellow Americans—tonight , we have gathered in a sacred space—the citadel of our democracy. 

In this Capitol, generation after generation, Americans have debated great questions amid great strife, and have done great things. 

We have fought for freedom, expanded liberty, defeated totalitarianism and terror. 

And built the strongest, freest, and most prosperous nation the world has ever known. 

Now is the hour. 

Our moment of responsibility. 

Our test of resolve and conscience, of history itself. 

It is in this moment that our character is formed. Our purpose is found. Our future is forged. 

Well I know this nation.
