Ethereum doesn’t care about your variables

Why storage slots are just dumb bytes and Solidity does the slicing Ethereum storage slots are just 32 raw bytes, a 256-bit word, usually shown as 64 hex characters with a 0x prefix. Slots don’t know types, addresses, or numbers. It’s the Solidity compiler and ABI that define how those bytes are sliced and interpreted.… Continue reading Ethereum doesn’t care about your variables

Solidity Storage Packing

TL;DR Writing about Solidity I’m deep-diving Solidity from the ground up to sharpen my understanding and share practical takeaways. This article collects my notes and examples, starting where it all begins: storage slots. Understanding how data lives in 32-byte words explains packing rules and gas costs. Once storage clicks, choosing the right types and using… Continue reading Solidity Storage Packing

The Oracle Problem in Blockchain: Why Chainlink Became the Most Trusted Source of Truth

Smart contracts can’t fetch data on their own. This article explains the oracle problem, why APIs aren’t enough, and how Chainlink solves it. Smart contracts are powerful: they execute code deterministically on-chain, without relying on human intervention. But they live in a closed environment(the blockchain) which cannot directly access external data like stock prices, weather… Continue reading The Oracle Problem in Blockchain: Why Chainlink Became the Most Trusted Source of Truth

Unveiling the Essence of APIs

Bridging Software Applications In the intricate landscape of software development, Application Programming Interfaces (APIs) emerge as silent architects, orchestrating seamless connections between diverse software applications. At its core, an API, or Application Programming Interface, is a set of protocols and tools that enables one software application to interact with another. It serves as a bridge,… Continue reading Unveiling the Essence of APIs

Smart contract development and security

Keeping security in mind is important when developing smart contracts and there are a number of different techniques and philosophies in regards to your smart contract development and security. Revisiting the NftFactory I was discussing earlier we’re deploying a new ERC721 from an address that isn’t verified so far. This could lead to anyone using… Continue reading Smart contract development and security
