Introdução a Padrões de Contratos e Compromissos — Forge College

How can choosing a contract pattern prevent silent state corruption and reduce gas costs in delegatecall-based systems? This lesson presents the conceptual map of the main contract patterns and the memory and gas trade-offs that define scalable architectures in Solidity. What you will learn: In this advanced lesson, you will understand the memory and call semantics of at least four pattern families (monolithic, proxy/delegate, linked libraries, clones/factories, and diamond) and how each affects storage ownership and layout. You will learn to compare deployment costs versus recurring costs per call, as well as storage write penalties. The lesson shows a step-by-step workflow for choosing a pattern based on contract size constraints, upgradeability, and gas budget. Finally, you will be able to interpret a proxy bytecode snippet and map its assembly behavior to delegatecall and slot layout semantics. Who it's for: Advanced Solidity developers who already know basic concepts like delegatecall, storage slots, and contract composition, and who want to make informed architectural decisions about scalability and updatable capabilities. Key topics covered: Contract patterns: monolithic, proxy (delegate-proxy), linked library, clone/factory, and diamond Storage ownership and slot layout; risks of incompatible slots Memory profile: where code and storage reside Gas trade-offs: deployment cost vs. cost per call and cost per write to storage Workflow for choosing a pattern based on constraints (size, upgrades, gas) Reading and interpreting proxy bytecode and mapping to assembly/delegatecall Want more practical lessons and materials for designing scalable contracts?
