Use Moralis Speedy nodes to detect new BSC contracts

Moralis General
#1

Hello,

I’m new to this, so I have a beginner’s question :slight_smile:

Is it possible to use a Speedy Node Moralis to browse new blocks and parse all transactions included in those blocks to detect new contract numbers.

If I understood correctly, when creating a new BSC contract, the creator performs a transaction on the BSC blockchain and therefore has to pay a fee.

Can we retrieve from the transactions the new tokens identifiers published on BSC?

I tried to look in a block explorer but I could not identify the transactions associated with the creation of a new contract nor the identifier of these new contracts.

Thanks in advance.

Hi,

Hello,

Thank you for your answer.

Here is the result I am looking for.

On the attached screenshot, you have a contract opening transaction (annotated 2) and the new contract ID (annotated 1).

you are interested in any created contract, or only in contracts that are new tokens?

#5

it looks like you can deterministically find out what will be the address of a new created smart contract: https://ethereum.stackexchange.com/questions/760/how-is-the-address-of-an-ethereum-contract-computed

Thank you for your answer.

Yes, I am looking to detect only new contracts.

Great link, thanks a lot!

Do you know how to detect new contract creation transactions to determine the addresses of these contracts from the issuer?

Hi,
It looks like you can check if an address is a contract or not:

you can use getcode function.
if the address is representing an External Owned Account you will get 0x as response otherwise you will get the contract's bytecodeode. for example :

web3.eth.getCode("0xa5Acc472597C1e1651270da9081Cc5a0b38258E3")
"0x"

and related to contract creation transactions, you could use a heuristic by the size of the transaction as the contract creation transactions also has to contain the contract code.

I use Listingspy.net, which is a project that keeps track of listings of new tokens in real time on all DEXs. Also analyzes + sorts fraudulent projects, taking into account the moment of significance.
