katana-web-crawling
Katana web crawling
Katana is a fast crawler/spider from ProjectDiscovery, aimed at automation pipelines (URLs in → discovered endpoints out). Official docs and flags: repository README and katana -h.
Scope and ethics
Use only on systems you own or are explicitly authorized to test (contract, bug bounty program rules, internal env). Crawl gently: set concurrency, rate limits, and depth to reduce load. Misuse can violate law and terms of service—you are responsible for your actions (tool ships with that warning).
Installation
Go (requires Go 1.25+ per upstream; verify current README if install fails):
CGO_ENABLED=1 go install github.com/projectdiscovery/katana/cmd/katana@latest

evm-solidity-defi-triage-agent
Guides EVM Solidity DeFi triage from public verified source or bytecode—access control, proxies, oracle usage, reentrancy and CEI patterns, DEX/router integrations, and common vulnerability classes. Use when the user asks for Ethereum or L2 smart contract security review, Solidity audit triage, OpenZeppelin proxy risks, or EVM-specific DeFi patterns—not for live exploits or private keys.
10crypto-market-structures
Summarizes descriptive concepts for max pain options theory, covered-call style crypto ETFs, crypto arbitrage families and risks, and bull/bear flag chart patterns—always as non-prescriptive education. Use when the user asks about max pain, premium income ETFs, arbitrage, funding rates, flash loans, or bull/bear flags in crypto trading context.
10honeypot-detection-techniques
Educational techniques to assess honeypot-style token risk from verified source, bytecode clues, and observational on-chain history—EVM ERC-20 patterns (transfer gates, fees, blacklists), Solana SPL and Token-2022 hooks, and safe validation paths. Use when the user asks how to detect honeypots, sell-restricted tokens, scam token mechanics, or static review checklists—not for deploying scams, stealing funds, or advising high-risk mainnet test trades on unknown contracts.
10solana-defi-vulnerability-analyst-agent
Guides discovery and documentation of Solana DeFi protocol risks from public code and chain state—Anchor/native programs, PDAs, CPIs, oracles, pools, SPL mechanics, and historical tx reconstruction. Use when the user asks for Solana program security review, DeFi vulnerability triage, PDA or CPI safety, oracle or liquidity-pool risk, launchpad/bonding-curve issues, or evidence-backed severity findings without exploits or private keys.
10crypto-investigation-compliance
Maps high-level crypto crime categories, safe and ethical OSINT plus on-chain investigation workflow, and victim reporting posture. Use when the user asks about scam types, pig butchering, rug pulls, tracing stolen funds ethically, compliance-adjacent investigation, or how to document cases for authorities.
10solana-tracing-specialist
Guides Solana-specific on-chain forensics—ATA resolution, SPL instruction parsing, transaction history via RPC and indexers (e.g. Helius-style APIs), fund-flow graphs, Solana clustering heuristics, and program authority review. Use when the user investigates Solana wallets, SPL tokens, DEX/Jito flows, rug or phishing patterns on Solana, or needs evidence-structured tracing reports with public data only.
