Hey there! Blockchain enthusiasts,

If you are interested in exploring the world of Ethereum or smart contract development, it promises to be an exciting journey. Before you dive deeper, let’s catch up on two crucial topics: security and scalability. 

Your smart contracts can attain a great shape if you master these tips. Let’s break it down to simple to start the journey to build scalable and secure smart contracts. 

Why Security is so Important?

You've likely heard about smart contract hacks, right? There were big ones in the past and it reminds us “Security is a big deal”. You don’t want your smart contract to be exploited by the hackers. So how could someone keep their smart contracts safe?

1. Always check user inputs: Never trust the user inputs blindly without validation. It’s like double-checking the door before leaving. 

2. Control: Make sure only the authorized person can handle certain parts of your smart contract. For example, set who can change or access the data or transfer tokens.

How to Build Secure Smart Contracts 

Use OpenZeppelin Libraries: These libraries are well-tested and audited by some of the best minds in the blockchain space. They provide you with reusable, secured smart contracts especially for ERC-20 tokens and other standards too, and help to avoid some common mistakes.

Use SafeMath: There were issues with underflow and overflow in Solidity and later it introduced SafeMath. Use SafeMath libraries when dealing with arithmetic operations. 

Contract upgradability:  Smart Contracts are immutable, right? Sometimes you need new updates and changes in smart contracts. Instead of locking, allow access to update safely without breaking anything.

Get an Audit: If you are serious about security, have your contract reviewed by any platforms or experts to find the potential issues, that are worth the penny. 

Why Scalability Matters?

Now, let’s talk about scalability. Scalability in Solidity allows to handle smooth transactions and users efficiently. It ensures the contract remains fast and cost-effective without causing any delays or high gas fees. 

Ethereum is getting too crowded. If many people try to interact at the same time, transactions may get delayed and gas fees can go through the roof. So, how could we make sure that smart contracts don’t crash?

How to achieve Scalability?

Reducing state changes and utilizing less expensive data types, among other effective coding techniques, to optimize gas use.

Combining transactions into batches to save on the time and expense of doing several tasks at once.

Putting off-chain computation into practice and handling complicated tasks outside the main Ethereum chain via layer-2 solutions (such as Optimism or Arbitrum).

Ready to start building?

The combination of security and scalability is the perfect setup for building smart contracts. Ethereum and Solidity are constantly evolving, so look out for updates and tools.
