Dapps Development Tutorials, Guides & Insights

This command will deploy your program to the Solana cluster you’ve configured (either localnet, devnet, or mainnet).

To interact with your newly deployed program, you can write a simple client script in Rust or JavaScript using Solana's web3.js library. Here's an example using JavaScript:

• Description: The most popular Ethereum block explorer and analytics platform.

• Avoid Storage in Loops: Writing to storage inside loops can quickly escalate gas costs. If you must use a loop, limit its execution or use memory instead of storage.
• Use Events for Logging: Instead of storing logs on-chain, use Solidity events. Events are cheaper and can be accessed off-chain by listening to logs.
• Optimize for Minimal Execution Paths: Design your smart contract functions to have the most common execution path consume the least gas.
• Leverage immutable and constant Keywords: For variables that won’t change after deployment, use immutable or constant to save on gas.
• Consider Upgradable Contracts: For complex contracts that may require changes over time, consider using upgradable contracts to avoid redeployment costs.

To understand the impact of gas optimization, let’s look at some real-world examples from popular Ethereum projects:

Steps to Set Up:

To build a DApp, you first need a smart contract that will serve as the backend logic. Let’s create a simple smart contract that allows users to store and retrieve a message on the blockchain.
