Cairo 1.x makes state mutations auditable by declaring storage with #[storage] and forcing explicit self.storage.field.read() and .write() calls. This declarative model improves reviewability, serialization safety, and interface clarity.
Decide when to use Vyper's built-in @nonreentrant decorator versus a manual reentrancy guard, with trade-offs, constraints, and a concrete implementation checklist.
Solidity custom errors replace costly revert strings with 4-byte selectors, cutting bytecode size and making reverts easier to decode off-chain.
Learn how to use fixed-size arrays in Vyper to prevent unbounded gas consumption and ensure deterministic memory usage in smart contracts.
Learn how to implement Vyper custom errors for gas‑efficient, clear failure handling. This guide covers requirements, minimal design, trust boundaries, operational checks, failure modes, and when to rethink the approach.
Clarity view functions let you read contract storage without gas. Learn how to declare, call, and verify them, plus common pitfalls and limits.
Replace require strings with Solidity custom errors to cut revert gas costs and get structured, decodable failure data. Works from 0.8.4 onward; requires ABI publishing for explorer support.
Explore how Polygon zkEVM achieves EVM equivalence through STARK-to-SNARK recursion and SMPT state representation, and how it impacts contract deployment.
Reach lets you write multi-party dApps once and compile to Algorand, Ethereum, or other backends. This guide explains participant roles, interact/commit consensus rounds, and a worked escrow example with frontend integration.
