I thought gas fees were simple. Turns out, they’re not. Here’s my dive into Ethereum gas, why fees fluctuate, and how devs optimize them. 🧵👇 #web3 #ethereum #crypto #web3Development

2/ Gas fees are what you pay to execute transactions on Ethereum. But why do they keep changing? The answer: network congestion & computation cost. Every smart contract operation has a gas cost (e.g., storing data costs more than reading it). The more complex your contract, the higher the gas.

3/ Then comes gas price (set in gwei). It’s like bidding for block space. Higher price = miners prioritize your transaction. But there’s a catch… EIP-1559 introduced a Base Fee & Tip model. Base fee adjusts dynamically per block, while tips (priority fees) incentivize miners. No more blind bidding!

4/ Okay, but how do smart contract devs optimize gas? I ran some tests. Here’s what I learned: ➡ Use calldata over memory (cheaper for function inputs) ➡ Pack storage variables (combine multiple `uint8` into a single slot) ➡ Short-circuit logic (e.g., `&&`)

5/ Example: I wrote two versions of a Solidity function. One used memory, the other calldata. Gas saved: ~30% just by changing a keyword.

6/ Another tip: Avoid unnecessary storage writes! Writing to storage is the most expensive operation (~20,000 gas per write). Use memory when possible. Gas optimization isn’t just about saving money—it’s crucial for scaling dApps. Lower gas = more users can afford interactions.

7/ My biggest takeaway? Every line of Solidity code costs gas. Writing efficient contracts isn’t optional—it’s a must.
