dvcrn Bounty Hunter
Automated smart contract vulnerability scanner for bug bounty programs. Uses free tools (Slither + local LLMs) for the heavy lifting, saves expensive models for PoC writing.
Requirements
slither-analyzer(pip): Static analysissolc-select(pip): Solidity compiler management- Node.js: For script execution
- Optional: Ollama with any code model for local triage
Quick Start
# Scan a repo
bash scripts/scan.sh <github-repo-url> [src-dir]
# Triage findings (uses local LLM if available, otherwise prints raw)
bash scripts/triage.sh <scan-output.json>
# Generate PoC template for a finding
bash scripts/poc-template.sh <finding-id> <contract-address>
Workflow
- Target Selection — Check Immunefi/Code4rena for active programs
- Clone & Scan —
scan.shclones the repo, installs solc, runs Slither - Triage —
triage.shfilters HIGH/MEDIUM findings, removes known false positives - Deep Dive — Only read code that Slither flagged (save your tokens)
- PoC — Use
poc-template.shto generate Foundry test scaffolding - Submit — Write up finding on Immunefi/Code4rena
Target Selection Criteria
Before scanning, check:
- Scope last updated within 30 days (fresh code = more bugs)
- Past payouts > $50K (they actually pay)
- GitHub repo in scope (not just deployed addresses)
- Solidity-based (Slither only works with Solidity)
Anti-Patterns
- Don't read entire codebases manually — let Slither scan first
- Don't spend > 1 hour on a target without a concrete lead
- Don't submit known issues (check past reports first)
- Don't ignore test coverage — untested code is where bugs hide
