feat: add Heimdall to Advanced Topics

[mnusurov]

Resource Addition/Update

Resource Information

• Name: Heimdall
• URL: https://github.com/Jon-Becker/heimdall-rs
• Category: Advanced Topics

Description

EVM bytecode decompiler, disassembler, and selector recovery toolkit for analyzing unverified contracts.

Why should this be added?

The Advanced Topics section had not been substantively updated since May 2026 and contained only two entries. Heimdall fills a clear gap: the list has security analyzers (Slither, Mythril, Aderyn) but no bytecode decompiler/disassembler. It is essential tooling when working with unverified contracts — bytecode-level analysis, selector/function signature recovery.

• 1,599 stars, 171 forks, last commit 2026-08-11 — comfortably clears the list's activity and popularity bar
• Note: canonical repo path is Jon-Becker/heimdall-rs; the old heimdall-rs/heimdall org path now 404s

Also fixes pre-existing alphabetical ordering in the section (Yul Documentation was listed before LearnEVM).

Additional Context

Vetted via the find-resources scouting process (GitHub search + web search + pre-vetted sources walk). Rejected near-misses: KEVM (formal methods research artifact, high barrier, Certora already covers FV for practitioners), EVM Deep Dives series (2022 Substack series, dated), ethereum/execution-specs (protocol spec, not a Solidity dev resource), learn-yul (stale 17 months).
