This is because there will be fees for each new data you will mine in the next block.
When smart contracts are implemented on a blockchain, the data from the contract is mined into the following block, which results in a small gas fee that is charged in the ether if the smart contract is implemented on the Ethereum blockchain.
If there are any vulnerabilities in the contracts, you can always rely on authentic smart contract security audit companies to eliminate them and save you from future malicious hacks.
This blog will discuss creating a copy of existing smart contracts in Ethereum. So brace yourself and read further to know how to do it easily.

The Factory Pattern
This is one of the most well-known programming patterns in which there is one basic concept: you don’t have to create instances of objects– the factory (single object) does it for you.
This happens with Solidity because smart contracts are objects. In this case, a contract will be the factory that will deploy multiple instances of other contracts.
Often, there is a case where we will require to create different types of objects, but we don’t know which type of object will instantiate until the time the code is executed at runtime. This is where the factory technique comes into play.
Generally, with the help of a basic factory contract, we can deploy multiple instances of the same contract, save them on the blockchain, and retrieve them whenever we need them.
What Are The Benefits Of Using Factory Pattern In Solidity?
These are the following advantages of using the factory pattern in Solidity:
- Deploying multiple contracts with high-gas efficiency.
- Reduce gas consumption on deploying multiple contracts
- Keep a check on all the contracts that you have deployed
When Should You Use The Factory Pattern?
Following are the situation in which the Factory pattern is most effective:
- In situations where we need to produce multiple instances of a smart contract quickie during runtime.
- In cases where the task is to deal with many smart contracts containing the same functionalities.
What Are The Types Of Factory Patterns In Solidity?
Talking about the Solidity smart contracts, we commonly implement two types of factors patterns. These include
- The normal factory pattern: This factory pattern is used when you want to deploy multiple instances of other contracts. It is done without any optimization to save gas on all the deployments.
- The cloned factory pattern: You can use this factory pattern when you want to deploy multiple instances of other contracts emphasizing gas optimization for each deployment.
Why Choose The Clone Factory Pattern?
Now that we will be deploying the same contract, there will be identical bytecode on every instance of the contract. So, there will be a lot of waste gas costs when we store all the bytecodes for every deployment.
The answer is a method that only deploys one instance of the Foundation contract and makes the rest of them act as proxies, passing calls to the first instance of the Foundation contract and allowing functions to run in the context of the proxy contracts. With this, each Foundation contract instance will have its own state and will only use the Foundation contract instance we established as a library.
Final thoughts:
In this blog, we’ve looked at the factory pattern, its advantages, its variations, and the situations in which it works best for smart contracts. Additionally, because of the cloned factory design’s gas cost-effectiveness, we have determined that it is the best pattern for deploying many instances of our Solidity smart contract. This way, it is possible to create a copy of the existing smart contracts in Ethereum.
There could also be other ways of doing it, which you can explore. The world of smart contracts is huge, and it all depends on how well you can dwell inside it to find the best possible solutions for the problems.
Hopefully, you’ve found this blog informative and helpful. Now, you can begin your crypto journey and get assistance from the best smart contract security auditing company.
