August 15, 2026 Smart Contract Testing: Unit vs Fuzz vs Invariant Testing (And When You Need Each)

Unit tests catch known bugs, fuzz tests catch unknown edge cases, and invariant tests catch broken system-wide guarantees — production contracts need all three, layered in that order.

August 14, 2026 ERC Token Standards Compared: ERC-20 vs ERC-721 vs ERC-1155 vs ERC-4626 vs ERC-6909

ERC-20 is for fungible tokens, ERC-721 for unique NFTs, ERC-1155 for mixed collections, ERC-4626 for tokenized vaults, and ERC-6909 is the gas-efficient multi-token standard replacing ERC-1155 in new builds.

August 13, 2026 Best Layer 2 for dApps in 2026: Arbitrum vs Optimism vs Base vs zkSync vs Polygon zkEVM
