What is ERC-1820: Pseudo-introspection Registry Contract?
As I was writing a post about ERC777, I had to explain ERC1820 as well, and in that process, I realized that ERC1820 needs a separate article. So let’s delve deeper into ERC-1820. You might be wondering why is it called a registry contract. Well, any contract or EOA

Part IV: Using libraries to optimize contract size
The topic of discussion in this article series has been the ways a smart contract developer can optimize the contract’s bytecode size & never hit the threshold of 24.576 kb. So here is another crucial development pattern you can use to lower the bytecode size of your contract.

Part I: Beware Solidity Devs, you might just hit your contract size limit
It's quite imperative for you as a Smart Contract Developer to always be within the pre-defined Smart Contract Bytecode size limit. Wait, What is Bytecode? 🤔 In very simpler terms, Humans understand Solidity, but EVM understands Bytecode. Bytecode is the low-level language that our solidity smart contracts (a high-level
