ZMOK provides enhanced Mainnet RPC and WS endpoints designed to optimize transaction propagation and ensure the quickest delivery of new blocks through its distributed architecture. Rapid transaction propagation is achieved by submitting transactions using the standard eth_sendRawTransaction method. Our architecture processes this method and submits it to an input relay for global distribution. Also by using the standard eth_sendRawTransaction method, users can benefit from rapid Tx propagation on web3 platforms that utilize MetaMask or comparable injected wallets.
Your transaction is sent multi-regionally. When you sign and send your transaction, it is sent to many nodes globally to increase the chances to be noticed by Builders & Validators. Your transaction is recognised in all regions globally. Without PREMIUM plan, it is sent to only one node assigned randomly, so your transaction may keep stuck in a location out of the region where the new block is mined. This way, 99.99% of sent transactions are processed in the next/newest block globally.
?> INFO: The order in this newest block is set by the gas you used. ZMOK does not set gas, transaction gas is set by you or the app you used.
| Method |
|---|
| eth_sendRawTransaction |
Transactions are sent using the method eth_sendRawTransaction. It requires your transaction to be already signed and serialized.
!> INFO: Transaction must be signed by your account before is sent to ZMOK. ZMOK has no way to unlock your local account.
You can use the ZMOK endpoint enhanced with RTP (Rapid Transaction Propagation) directly in your code, or paste it as a custom RPC to your wallet. Both are using eth_sendRawTransaction method.
Sample code:
// sendRawTransaction.js
const Web3 = require('web3')
const Tx = require('ethereumjs-tx').Transaction
// connect to ZMOK endpoint enhanced with RTP
const web3 = new Web3(new Web3.providers.HttpProvider('https://api.zmok.io/mainnet/your-app-ID'))
// the address that will send the test transaction
const addressFrom = 'FROM-ADDRESS'
const privateKey = Buffer.from('YOUR-PRIVATE-KEY', 'hex')
// the destination address
const addressTo = 'TO-ADDRESS'
// construct the transaction data
// NOTE: property 'nonce' must be merged in from web3.eth.getTransactionCount
// before the transaction data is passed to new Tx(); see sendRawTransaction below.
const txData = {
gasLimit: web3.utils.toHex(25000),
gasPrice: web3.utils.toHex(10e9), // 10 Gwei
to: addressTo,
from: addressFrom,
value: web3.utils.toHex(web3.utils.toWei('1', 'ether')) // thanks @abel30567
// if you want to send raw data (e.g. contract execution) rather than sending tokens,
// use 'data' instead of 'value'
// e.g. myContract.methods.myMethod(123).encodeABI()
}
/** Signs the given transaction data and sends it. Abstracts some of the details of
* buffering and serializing the transaction for web3.
* @returns A promise of an object that emits events: transactionHash, receipt, confirmation, error
*/
const sendRawTransaction = txData =>
// get the number of transactions sent so far so we can create a fresh nonce
web3.eth.getTransactionCount(addressFrom).then(txCount => {
const newNonce = web3.utils.toHex(txCount)
const transaction = new Tx({ ...txData, nonce: newNonce }, { chain: 'mainnet' }) // or 'rinkeby'
transaction.sign(privateKey)
const serializedTx = transaction.serialize().toString('hex')
return web3.eth.sendSignedTransaction('0x' + serializedTx)
})
// fire away!
sendRawTransaction(txData).then(result => {
console.log(result)
}
)WALLET-USERS: Add the ZMOK endpoint enhanced with RTP (Rapid Transaction Propagation) to your wallet (e.g. MetaMask or Brave):
Navigate to the Networks dropdown menu and click "Add Network". Paste your RPC URL. Set the Chain ID to 1 (ignore an error message). Save. MetaMask or another wallet provider will use eth_sendRawTransaction automatically.
With the Premium ZMOK plan, users gain unparalleled access to pending and queued transactions across multiple regions, providing a broad and insightful perspective.
While accessing the Tx mempool from a single node typically yields about 2,000 to 6,000 transactions from the mempool, the ZMOK global TX mempool significantly amplifies this capacity. Users can now access more than 120,000 to 160,000 pending and queued transactions in real-time, transforming the way they interact with the transaction pool. an 120-160k pending/queued transactions in real-time.

Returns a list with the exact details of all the transactions currently pending and queued based on the input query.
Parameters:
- query - (optional) SQL-like filter query
More details:
To decode input data of any known transaction you could use this library:
https://github.com/miguelmota/ethereum-input-data-decoder
Alternatively, you could resolve the smart contract method from the method signature (the first 4-bytes from the input) by using these public databases:

- https://www.4byte.directory/signatures/?bytes4_signature=0x38ed1739
