Exploring Precompiled Contracts on Ethereum: A Deep Dive | by Lucas Martin Calderon | Medium
Ethereum, a leading decentralized platform, offers native, highly optimized functions known as precompiled contracts. Precompiled contracts are a set of core routines integral to Ethereum’s cryptographic functionalities. In this comprehensive guide, we will explore these contracts, their creation process, and their application in Solidity using in-line assembly. Precompiled contracts on Ethereum are like the platform’s built-in functions, they live at specific addresses starting from 0x1 to 0x8 and offer specific, often cryptographic, functionality. Here are a few of them: A precompiled contract in Go Ethereum (geth), Ethereum's client implementation, would look something like this: Here, we define a map of precompiled contracts. The keys are the contract addresses, converted from bytes to a common Ethereum address format. The values are the corresponding contract implementations. Solidity, Ethereum’s native language, has most precompiled contracts’ functionalities readily available as
