Verification If a Transaction is In Mempool Using Infa Apis
. API from Infra and the implementation of a solution based on JavaScript with Web3.js.
Approach 1: Using eth_gettransactionbyhash API
API `eth_gettransctionbyhasha allows you to recover a translation by its hash. However, it is worth noting that this
Here are the Steps:
1.
- ReplaceTargethatha with the actual hash you want to check.
`JavaScript
Const Web3 = Requires (‘Web3’);
Const infuraurl = ‘
CONTIST SUPPLIER = NEW WEB3.PROVIDERS.HTTPROVIDER (INFURAURL);
// Build the Ethereum Address of the Miner Who Created The Transaction
Const mineraddress = ‘0x …’;
// Build the Target Hash of the Transaction You Are Interested In
Const Targethash = ‘0x …’;
Web3.etth.gettranstranstionbyhash (Supplier, {from: Mineraddress}, {
Data: 0x $ {TARGETHAST},
})
.Hen ((transaction) => {
console.log (transaction);
If (transaction.isinmempool ()) {
console.log (‘the transaction is in mempool’);
} Else {
console.log (‘the transaction is not in mempool’);
}
})
.catch ((error) => {
Console.Error (Error);
});
`
Approach 2: Using JS Web3.js and Infa Apis
For a simpler approach, This method takes an optional hash parameter.
Here's how to do it:
JavaScript
Const Web3 = Requires (‘Web3’);
Const infuraurl = ‘
CONTIST SUPPLIER = NEW WEB3.PROVIDERS.HTTPROVIDER (INFURAURL);
// Build the Ethereum Address of the Miner Who Created The Transaction
Const mineraddress = ‘0x …’;
// Build the Target Hash of the Transaction You Are Interested In
Const Targethash = ‘0x …’;
Web3.eth.gettranscation ({
From: Mineraddress,
Gasprice: Web3.utils.towi (’20 ‘,’ Gwei ‘),
})
.Hen ((transaction) => {
console.log (transaction);
If (transaction.isinmempool ()) {
console.log (‘the transaction is in mempool’);
} Else {
console.log (‘the transaction is not in mempool’);
}
})
.catch ((error) => {
Console.Error (Error);
});
`
Conclusion
Mempol. However, the use ofeth_gettransctionbyhasha provides more information about the transaction and its inclusion state. The JS Web3.Js Method is a simpler solution.
