A practical task guide for adding Vyper's @nonreentrant decorator to state-changing functions, verifying it blocks reentrant calls on a local node, and planning recovery if the lock triggers in production.
A practical guide to separating expected failures from internal bugs in Vyper contracts using raise and assert, including verification steps and recovery options.
Learn how to implement Mainnet Forking in Hardhat to test smart contracts against real-world blockchain state without risking production funds.
Learn how to use Solidity's unchecked blocks to eliminate redundant overflow checks and reduce gas costs in high-frequency arithmetic operations.
Decide when to use Hardhat’s in‑process EVM versus a pinned mainnet fork, compare trade‑offs, and see a concrete configuration with validation steps.
Vyper's @nonreentrant decorator gives you a storage-backed mutex with one line of code. This post shows a worked withdraw() example comparing manual checks-effects-interactions vs. the decorator, the gas/composability trade-offs, and a verification checklist to prove the lock actually holds.
Learn how Polygon PoS achieves EVM compatibility, allowing developers to deploy Ethereum smart contracts without code changes while balancing the trade-offs of sidechain security.
Vyper's nonpayable-by-default model eliminates implicit Ether acceptance, reducing the attack surface by requiring explicit @payable decorators for all value entry points.
Learn how to replace expensive string-based reverts with Solidity custom errors to reduce gas costs, improve ABI decoding, and implement typed error handling.
