USE THE ETHEREUM GATEWAY

Once you have an Ethereum gateway — meaning that you create a new gateway with a
target of Ethereum — you can interact with different Ethereum networks by
specifying the correct JSON blob for your query.


READ FROM THE NETWORK

The Cloudflare Ethereum Gateway allows HTTP requests where the body of the
request is set to be the JSON body of the request you would like to make. For
example, if you would like to read the block that is at number 0x2244, then your
JSON blob takes the form:

{ "jsonrpc": "2.0", "method": "eth_getBlockByNumber", "params": ["0x2244", true], "id": 1 }


Copy Button

Each blob use a valid method parameter. The params array here contains the block
number that we would like to locate and a boolean expressing whether each
individual transaction in the block should be shown in their entirety (true) or
as stubs (false).

To send this query to your custom Ethereum Gateway, you could use a cURL
command:

$ curl https://web3-trial.cloudflare-eth.com/v1/mainnet -H 'Content-Type: application/json' --data '{"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["0x2244", true],"id":1}'


Copy Button

You can also write the same query using the JS Fetch API:

await fetch(
  new Request('https://web3-trial.cloudflare-eth.com/v1/mainnet', {
    method: 'POST',
    body: JSON.stringify({
      jsonrpc: '2.0',
      method: 'eth_getBlockByNumber',
      params: ['0x2244', true],
      id: 1,
    }),
    headers: {
      'Content-Type': 'application/json',
    },
  })

).then(resp => {
  return resp.json();

});


Copy Button

The response in both cases will be a JSON blob of the form:

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "difficulty": "0x746ef15b66",
    "extraData": "0x476574682f76312e302e302f6c696e75782f676f312e342e32",

WRITE TO THE NETWORK

Currently, the Ethereum Gateway allows you to write to the network using the
eth_sendRawTransaction RPC method. This creates a new message call transaction
or a contract creation for signed transactions. The transactions are signed
using a secret key corresponding to your own Ethereum walletExternal link icon
Open external link .

Once you have a wallet set up and a method of signing your own transactions, you
can write that transaction to the Ethereum network via the Cloudflare Ethereum
Gateway. Signed transactions use hexadecimal strings of the form:

"0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675"


Copy Button

Then you can use your custom Gateway to send the transaction to the network with
a cURL command:

$ curl https://web3-trial.cloudflare-eth.com/v1/mainnet -H 'Content-Type: application/json' --data '{"jsonrpc":"2.0","method":"eth_sendRawTransaction","params":["0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675"],"id":1}'


Copy Button

You could also use a JS Fetch API request:

await fetch(
  new Request('https://web3-trial.cloudflare-eth.com/v1/mainnet', {
    method: 'POST',
    body: JSON.stringify({
      jsonrpc: '2.0',
      method: 'eth_sendRawTransaction',
      params: [
        '0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675'
      ],
      id: 1,
    }),
    headers: {
      'Content-Type': 'application/json',
    },
  })

).then(resp => {
  return resp.json();

});


Copy Button

(The actual command above will not work — you need to provide your own signed
transaction.)
