Deploying to Polygon's PoS chain can cut transaction costs dramatically, but it's a sidechain, not a rollup. Here's how to evaluate, test, and integrate it honestly.
Vyper's @nonreentrant decorator turns reentrancy from a code-review convention into a compiler-enforced guarantee. Here's how it works, a vault example, and where it falls short.
Learn how Vyper implements native overflow protection and bounds checking to prevent common smart contract vulnerabilities without needing external libraries.
Use a single Reach backend to describe a two-party protocol and let the compiler generate per-participant contract code and JavaScript clients for Algorand or Ethereum, keeping on-chain logic separate from UI and I/O.
Clarity maps give you typed, persistent key‑value storage on Stacks. This post walks through a real‑world example, shows the costs, and explains when to batch writes or avoid deep nesting.
Vyper makes overflow and underflow protection mandatory — no opt-out, no annotations. Here's what that costs in gas, what it buys in auditability, and when the trade-off matters.
Solidity's immutable keyword eliminates constructor storage writes and turns reads into cheap immediate loads. This post shows a fee-collector example, measures ~45k gas saved on deployment, and outlines when immutability is the wrong choice.
Vyper’s checked arithmetic and explicit reentrancy lock reduce common smart‑contract bugs. A minimal vault example shows how default safety can replace Solidity’s opt‑in libraries.
Clarity post-conditions are mandatory safety rails that constrain which asset movements a contract may perform. This guide shows how to declare them, a worked STX-token swap example, common mistakes, and how to verify enforcement on Stacks.
