Loop Decoder

Semgrep is a pattern-based static analysis tool with rulesets for Solidity vulnerabilities. Builders run those rules over a codebase to catch known vulnerable patterns and style issues before review.

heimdall-rs is a Rust EVM toolkit that disassembles bytecode, decompiles contracts, generates control flow graphs, and decodes calldata and traces. Builders reach for it when they need to understand a contract that has no published source.

sol2uml generates UML class and storage-layout diagrams from Solidity source or from verified contracts. Builders run it to see contract relationships and how state variables are packed into storage.

CodeTracer 是一個使用者友善的時間旅行除錯器，旨在支援廣泛的 web3 程式語言。

EDB 是一個用於 Solidity 執行的原始碼層級除錯器，提供單步執行、區域變數、監看式和中斷點功能，當您需要對鏈上或測試中的合約行為進行 IDE 等級的檢視時，它會是您的理想選擇。

Tenderly provides transaction simulation, trace debugging, alerting, and Virtual TestNets for contracts. Builders use it to replay a failing transaction, watch deployed contracts, and test against a forked network.
