Learn how to add Hardhat’s forking to continuous‑integration workflows with a lean config, trust boundaries, sanity checks, and how to detect stale forks that could break your tests.
Learn how to reliably pull historic Transfer events from an ERC‑20 contract using web3.js, bounded block windows, a confirmation buffer, and a resumable checkpoint. Handle provider limits, reorgs, and API differences between v1 and v4.
Nano’s zero‑fee, instant‑finality design relies on a block‑lattice, lightweight PoW, and Open Representative Voting. This blog explains how these engineering choices work together, shows a concrete transaction example, and discusses trade‑offs like spam resilience and centralization risk.
Developers want to use Vyper’s block.timestamp to trigger contract logic based on a specific regional time zone, such as executing a function at 09:00 local time each day. Because block.timestamp returns UTC epoch seconds and Vyper provides no native timezone‑aware conversion functions, the implementation must rely on custom arithmetic or external libraries,
