# 🪞 [GUIDE] Colab + VS Code Bridge — Free T4 GPU + Local Workflow + Money-Making Stack + Zero Setup Cost ![image](https://onehack.st/uploads/default/original/3X/d/e/de614710bb672623212c0b3ed6646a110a94812a.jpeg) > **Google has killed the GPU mafia.** > **VS Code now connects directly to Google Colab.** → **Free T4 GPU inside your editor.** → **Your local files. Their compute.** > **[Google Colab is Coming to VS Code- Google Developers Blog](https://developers.googleblog.com/google-colab-is-coming-to-vs-code/)** > > Connect your VS Code notebooks to Colab's powerful runtimes with the new Google Colab extension, bringing the best of both platforms together. * * * ### 🪦 Chegg was worth $14 billion. Last week: $108 million. ChatGPT ate the rest. There’s exactly **one rule** that decides if this free GPU prints you money — or makes you the next Chegg. Open the first box. Then pick a hustle from any of the seven below it. ↓ * * * > **🧱 The one rule — read this first or skip the whole post** > > Picture a wall. > > **On one side** sits everything ChatGPT, Claude and Gemini can do for $20/month. Essays. PDF summaries. Emails. Small scripts. Homework help. > > **On the other side** sits everything they physically _cannot_ do, even if you paid them $2,000/month. Audio. Video frames. 3D meshes. Files that legally can’t leave the customer’s machine. Bulk runs of 10,000 jobs. Real-time pipelines. > > The free T4 GPU only prints money on the **far side** of the wall. The near side is Chegg in slow motion — Blockbuster died to Netflix the same way, the cassette tape was the wall. > > The seven boxes below = the seven kinds of “far side.” Every hustle inside each box is one ChatGPT cannot reach. ([Chegg’s full $14B collapse, written up two weeks ago](https://europeanbusinessmagazine.com/business/chegg-stock-collapse-chatgpt-ai-disruption-2026/)) * * * ### 🎯 Twenty hustles, sorted by which kind of far-side they live on > **🎧 The audio side — songs, voices, old tapes** > > **🎙 Song stem splitter** — Pull vocals/drums/bass out of any song in 30 seconds using Demucs (Meta’s open-source audio separator). Sell to DJs and remixers at **$10-30/song**. > > **🗣 Voice cloning service** — Train a custom voice clone in 20 minutes (XTTS-v2 or RVC). Audiobook narrators, dubbing studios, accessibility users pay **$30-100/clone**. > > **📻 Old audio restoration** — Clean up vinyl rips, cassette tapes, voicemails from deceased relatives (Demucs + custom denoising). **$30-100/track.** > > **🎶 Music style-transfer remixer** — Take a song’s stems, generate a new version in a different genre (AudioLDM2). DJs pay **$30-100/track** for legally-distinct remixes. > > **Why no $20 AI plan touches this:** none of them process audio files at all. iZotope, the SaaS alternative, costs $400 per seat. > **🎬 Moving pictures — dubbing, clips, animated portraits** > > **💋 Lip-sync video dubbing** — Dub a creator’s video in Hindi or Spanish, then make their lips actually match the new language (Wav2Lip). **$50-200/video.** > > **🎥 Text-to-video clip factory** — Generate short AI clips for TikTok content farms (CogVideoX or LTX-Video). Sell in packs at **$5-20/clip**. > > **📸 Photo-to-motion animator** — Turn a still portrait into a 3-second talking or moving clip (Stable Video Diffusion). Memorial videos, dating profiles, social posts at **$20-50/clip**. > > **🤸 Pose-controlled storyboards** — Animators send stick figures, you send back rendered scenes matching the exact poses (ControlNet OpenPose). **$50-200/scene.** > > **Why no $20 AI plan touches this:** Sora is $200/month with waitlists; Veo is enterprise-only; Midjourney can’t accept pose maps as input. > **🧊 3D meshes — for printers and indie game devs** > > **🖨 Photo → 3D print model** — Customer sends a photo of an object, you send back a printable 3D mesh in 60 seconds (TripoSR or Stable Zero123). Etsy 3D-print shops and indie game devs pay **$20-100/model**. > > **Why no $20 AI plan touches this:** none of them output 3D mesh files. Not even close. > **🛡️ The fortress — files that legally can't leave the customer's machine** > > **⚖ Lawyer / doctor document AI** — Summarize 500-page legal cases or medical records on a local LLM (Mixtral 8x7B fits a T4). **$200-500/document.** > > **✍ Handwritten manuscript OCR** — Fine-tune OCR on a specific handwriting style (medieval Latin, doctor scripts, grandma’s letters). Genealogists, archives, historians pay **$200-1000/archive**. > > **🧾 Receipt and invoice extractor** — Process 1000 receipts an hour for accountants and bookkeepers (LayoutLMv3 fine-tuned). **$0.05-0.20/receipt.** > > **Why no $20 AI plan touches this:** uploading attorney-client material or HIPAA-protected data to ChatGPT is a career-ending mistake. The data legally cannot leave the customer’s machine — your local Colab keeps it on theirs. > **🌙 The midnight machine — 10,000 jobs while you sleep** > > **🛒 Bulk background remover** — Process 10,000 product photos overnight (`rembg` or BRIA RMBG) for dropshippers and Shopify stores. **$0.10-0.50/image** , money on volume. > > **🗺 Tabletop RPG battle map mill** — Generate custom D&D / Pathfinder maps (SDXL + ControlNet). Roll20 and Foundry users pay **$20-50/map** , 200 maps a day possible. > > **🕷 24/7 web monitor + classifier** — Scrape 5,000 sites continuously, classify alerts with a local LLM. Sell competitive intelligence reports to brands at **$200-2,000/month**. > > **Why no $20 AI plan touches this:** ChatGPT API at this volume costs $3,000+/month and gets rate-limited; Midjourney’s terms ban bulk commercial resale. > **⚡ Live and instant — when the cloud is too slow** > > **📺 Real-time Twitch stream translator** — Live audio → live translation → live subtitle overlay (Whisper + LLM + TTS pipeline). Streamers expanding internationally pay **$50-100/month/streamer**. > > **🎤 Real-time voice filter for streamers** — Custom-trained voice changer running **live** on Twitch and Discord (RVC). **$50 setup + $20/month** per streamer. > > **Why no $20 AI plan touches this:** cloud API round-trip is 300-500ms, which breaks the illusion. Local GPU is sub-50ms. > **🧬 Train your own — niches no consumer AI ever learned** > > **🏢 Industry-specific fine-tuned chatbot** — Train a small LLM on a niche industry’s jargon (dental coding, kosher law, oil-rig safety standards). Sell as B2B SaaS to that single industry. > > **🌏 Rare-language document translator** — Fine-tune NLLB-200 on Quechua, Hmong, Tigrinya, Hausa. UN contractors, immigration lawyers, NGOs pay **$0.10/word**. > > **🪙 Crypto wallet cluster analysis** — Train a graph neural network on public blockchain data to cluster wallets back to owners. OSINT investigators and asset-recovery firms pay **$500-5,000/case**. > > **Why no $20 AI plan touches this:** ChatGPT only lets you prompt. The accuracy gap that pays your bills lives inside the training step, which only your local GPU can do. ChatGPT also cannot run graph neural networks. * * * > **🪤 The catch nobody tells you (read this BEFORE you start)** > > **Colab Free** disconnects after 12 hours and kills runtime after 90 idle minutes. Their ToS bans “long-running background tasks” and “sustained commercial workloads.” Three workarounds: > > 1. **Colab Pro at $9.99/month** lifts most limits. Break-even is day three of any hustle above. ([Live T4 pricing across 8 platforms, tracker quotes 5,000+ instances in real time](https://gputracker.dev/blog/google-colab-alternatives)) > 2. **Stack the free tiers** — Colab Free (~30 hrs/week) + Kaggle Notebooks (30 hrs/week of P100) + Lightning AI starter credits ≈ **60-90 hours of free GPU per week** total. > 3. **Architect for resume** — every job idempotent, every state file in your local VS Code project. Runtime can die; your work doesn’t. > > When you outgrow free, the real graduation path is **Lightning AI at $0.29/hr T4 pay-as-you-go** (persistent IDE, attach/detach GPU, no session resets) — not RunPod. RunPod wins for dedicated inference endpoints once you’re past ~$2K MRR. > > Big lesson from real operators — [KYG Trade’s AI assistant passed the US Customs Brokers License Exam at 93% in October 2025](https://www.newswire.com/news/kygs-ai-assistant-kay-passed-the-october-2025-u-s-customs-brokers-22678300). Well-funded vertical AI WILL eventually enter any market you prove out. Pick a vertical small enough they won’t bother (probate paralegals, not Big Law). * * * ### 🪧 The simple-pimple Chegg lost **$14 billion** learning you cannot beat ChatGPT by wrapping ChatGPT. The free T4 in VS Code only pays for things ChatGPT physically _cannot reach_ — the seven sides above. Pick **one** hustle from **one** side. Build the smallest version this weekend. Sell it once for $20 to prove the loop closes. Raise the price every five sales until people start saying no. Don’t be Chegg. ---

@diegoxdeus — HMmm.., **zero programming** for this one. If you can click a Play button, you can run the whole stack. Stop overthinking it. Everything below is click → wait → download → upload-to-sell. That’s the entire job. Open the boxes 👇 * * * > **🧰 Step 1 — The tool that does all the work (Fooocus, no code shit)** > > Fooocus = Stable Diffusion XL but with a Midjourney-style box where you type and click. No code anywhere on this page. > > How: > > 1. Open → [**Fooocus official GitHub**](https://github.com/lllyasviel/Fooocus) > 2. Scroll the README, find the **“Open in Colab”** button > 3. In Colab, hit **Runtime → Run all** > 4. Wait ~3 mins. A web window pops open with a prompt box > 5. Type → click Generate → download > > If that’s still too bare-bones for you, use this pre-built one — it has dropdown menus for everything (LoRAs, models, upscalers), zero typing required: > > 🔗 [**AIO Free Colab — Fooocus + Flux all-in-one**](https://civitai.com/articles/10795/aio-free-colab-fooocus-and-flux1-d) > > That’s literally it. Anyone calling this “programming” is lying to you. > **🗺️ Step 2 — The battle map LoRAs (free, plug-and-play)** > > LoRAs = the “style brain” that turns generic AI output into “holy shit that’s a Roll20-ready battle map.” All free downloads: > > - 🆕 [**DnD Battlemaps Generator**](https://civitai.com/models/2164519/dnd-battlemaps-generator) — Nov 2025, top-down vector style, the best one out right now > - 🗺 [**Mapcraft: The Ultimate TTRPG Mapmaker**](https://civitai.com/models/799901/mapcraft-the-ultimate-ttrpg-mapmaker) — fantasy, sci-fi, modern, post-apoc — covers everything > - 🔍 [**D&D Battlemaps SDXL + 2× Upscaler**](https://civitai.com/models/1073005/dandd-battlemaps-sdxl-10) — has an upscaler bundled so your maps don’t look like ass on a 4K screen > > Workflow: Civitai page → click Download → `.safetensors` file lands on your PC → upload to Fooocus’s LoRA folder via the AIO Colab’s upload widget → it appears in the LoRA dropdown. Done. > **💰 Step 3 — Where you actually get paid (4 channels, easiest first)** > > **1. Patreon — the real money. Stop sleeping on this one.** Subscribers \> one-time buyers. Study the format from real earners: > > - [**Cropox Battlemaps**](https://www.patreon.com/cw/CropoxBattlemaps) — 4 tiers, 4+ maps/month, 175+ map archive > - [**Heroic Maps**](https://www.patreon.com/cw/heroicmaps) — $5 / $8 / $12 tiers, 9 maps/month, profitable since 2013 > - [**Beneos Battlemaps**](https://www.patreon.com/cw/BeneosBattlemaps) — quit their fucking day jobs doing this > - [**Tom @ Tabletop Things**](https://www.patreon.com/tabletopthings) — animated WebM maps > > **2.

Roll20 Marketplace** — auto-cross-lists to DriveThruRPG once you’re in. [Partner sign-up here](https://roll20partners.zendesk.com/hc/en-us/articles/10818669735575). > > **4. Etsy** — bundle 20 maps into a ZIP, list at $5–15. Search “battle map pack” first, copy the top sellers’ listing structure, undercut by a buck. > **📈 Step 4 — Honest reality check (don't quit your job day one)** > > - **Week 1:** Just get Fooocus running. Generate 5 maps. Don’t sell shit yet. Post them free on [r/battlemaps](https://www.reddit.com/r/battlemaps/) and [r/UnearthedArcana](https://www.reddit.com/r/UnearthedArcana/). Watch the upvotes — that’s your free market test. > - **Month 1:** Patreon live at $3 / $5 tiers. Post 1 free map a week on Reddit, drop your Patreon link in the **comment** (not the post body — that gets you banned). First 20 patrons ≈ $60–100/month. > - **Month 3–6:** 100 patrons ≈ $300–500/month. The pros above sit at $4K–$15K/month and they’ve grinded 5–10 years to get there. > - **DriveThruRPG:** slow burn. List 1 pack/week. Expect $10–50/pack/month after ~6 months of catalog build. > > Anyone telling you “make $5K in week one” is selling you a course. Don’t fucking buy the course. > **🪤 Step 5 — The unfair edge no one's running (because they don't have free GPU)** > > This is the part 90% of map sellers can’t do because they’re stuck on a laptop without a real GPU: > > **Animated battle maps.** Take your finished still map → run it through **Stable Video Diffusion** (works on ComfyUI on Colab) → out comes a 3-second water-ripple, torch-flicker, or fog loop. > > Animated maps sell at **3× the Patreon tier** of static ones, and only ~4 creators on the planet ship them at scale right now: > > - [Beneos Battlemaps](https://www.patreon.com/cw/BeneosBattlemaps) > - [Dynamic Dungeons](https://graphtreon.com/creator/blubbedi) > - [Tom @ Tabletop Things](https://www.patreon.com/tabletopthings) > > That’s the entire reason a free GPU matters for this hustle. Static maps you fight 500 sellers. Animated, you fight 4. * * * ### 🪧 The simple-pimple Tonight, just do **one** thing: open Fooocus’s Colab link → hit Run all → generate one map → post it free on r/battlemaps. No selling. No accounts. No Patreon page. Just generate one and ship it. If the upvotes feel good, you’ll know. If they don’t, you’ve burned 30 minutes — no harm done. Drop questions back here if any step breaks. Programming literally never enters the picture, anywhere, at any point. 🤝 ---

@SRZ How do I go about the 24/7 web monitor + classifier? ---
**Author:** ![Ze380y](https://onehack.st/user_avatar/onehack.st/ze380y/32/48760_2.png) [@Ze380y](https://onehack.st/u/Ze380y)\ **Post date:** [July 13, 2026, 2:50pm UTC](https://onehack.st/t/guide-colab-vs-code-free-t4-gpu-money-making-stack/322012/8 "2026-07-13T14:50:06Z")
@scarywiteghost the thing that trips everyone on this one: **the monitor and the classifier are two different machines.** Watching sites is cheap network work — that runs 24/7 on a _free always-on_ box. The T4 only wakes up to classify the new stuff, in bursts. Try to run the clock _on_ Colab and it dies every ~12h. Split them and it’s genuinely free. Boxes below build it piece by piece 👇 > **🧠 The whole thing in one picture — before you touch a single tool** > > Four stages, each dead simple: > > 1. **Watch** — a tiny always-on script checks your list of sites on a schedule (every 15min / hour). Runs free on GitHub Actions cron, an Oracle free VM, or Cloudflare Workers. No GPU. > 2. **Catch changes** — instead of re-reading whole pages, diff the cheap signal: a site’s `sitemap.xml`, its RSS feed, or a saved copy vs the new one. New line = new thing to look at. > 3. **Classify (this is the only GPU part)** — pile up the day’s changes, send the batch to Colab, a local model tags each one (“competitor dropped price”, “new hire”, “product launch”), Colab sleeps again. > 4. **Sell** — the tagged alerts become a weekly one-page report per brand. That’s the $200–2,000/mo product. > > The magic: stage 3 is the ONLY thing that needs the T4, and it runs maybe 10 min a day. Everything else is free forever. > **👀 Stage 1+2 — watch thousands of sites for basically free (no GPU)** > > Don’t crawl every page every time — watch the _change-feed_ each site already publishes: > > - [git-scraper-template (simonw)](https://github.com/simonw/git-scraper-template) — a GitHub Action fetches a URL on a cron and commits it. **The git diff between commits IS your change log, free forever.** The purest version of this whole hustle. > - [changedetection.io](https://github.com/dgtlmoon/changedetection.io) — the classic self-host watcher (visual + text diff, notifications) if you want a UI. > - [webchanges](https://github.com/mborsetti/webchanges) — CLI version, watches URLs _and_ shell commands, runs headless on cron. > - [sitemap-monitor](https://github.com/drobnikj/sitemap-monitor) — treats a site’s `sitemap.xml` as the feed: new `` = new product/page. One tiny fetch instead of crawling the whole site. > - [RSSHub](https://github.com/DIYgod/RSSHub) — turns almost anything (社媒, news, niche sites) into an RSS feed you can poll cheaply. > **🕶️ When a site fights back — scrape 5,000 without getting blocked** > > Most sites don’t need a browser at all — fake the fingerprint and use plain HTTP: > > - [curl\_cffi](https://github.com/lexiforest/curl_cffi) — HTTP client that impersonates a real browser’s TLS fingerprint. No browser needed = the cost-killer for ~80% of sites. > - [nodriver](https://github.com/ultrafunkamsterdam/nodriver) — for the ones that _do_ fight; talks straight to Chrome, passes Cloudflare/Imperva cleanly. > - [FlareSolverr](https://github.com/FlareSolverr/FlareSolverr) — solves a Cloudflare challenge once, hands back the cookie so your cheap workers reuse it. > - [Scrapling](https://github.com/D4Vinci/Scrapling) — self-healing selectors that auto-fix when a site changes its HTML (a 24/7 monitor’s #1 failure). > - **The sneaky one:** [gau](https://github.com/lc/gau) / [katana](https://github.com/projectdiscovery/katana) pull a site’s known URLs from Wayback / Common-Crawl indexes — **you learn what changed without ever hitting the site.** > **🤖 Stage 3 — the classifier on the T4 (skip the heavy LLM, mostly)** > > You barely need a big LLM. A **zero-shot classifier** takes your text + your labels and sorts it, no training: > > - [comprehend\_it-base](https://huggingface.co/knowledgator/comprehend_it-base) — small, beats the usual `bart-large-mnli`, drop-in. > - [GLiClass](https://github.com/Knowledgator/GLiClass) — encodes text + all your labels in ONE pass (~10x faster); change the label list per brand with zero retraining. > - [mDeBERTa-xnli](https://huggingface.co/MoritzLaurer/mDeBERTa-v3-base-xnli-multilingual-nli-2mil7) — same thing in 100 languages, so foreign competitor sites classify without translating. > - **Pre-filter for free:** [model2vec](https://github.com/MinishLab/model2vec) / [FastEmbed](https://github.com/qdrant/fastembed) turn text into embeddings on plain CPU — throw away the boring 90% _before_ it ever reaches the T4. Only the interesting bits burn GPU. Use a real LLM ([Ollama](https://github.com/ollama/ollama)) only when you need a written summary. > **🧩 Don't build it from scratch — ready-made monitor→classify→report stacks** > > - [ScrapeGraphAI](https://github.com/ScrapeGraphAI/Scrapegraph-ai) — scrape + local-LLM extract as one graph, exactly this shape; start here if you want it all in one tool. > - [changedetection.io](https://github.com/dgtlmoon/changedetection.io) + its webhook → pipe alerts straight into your classifier. > - [git-history (simonw)](https://github.com/simonw/git-history) — turns your scraped commits into a queryable SQLite of _what changed when_ — that table basically writes the client report for you. > > Full rare-tool list (anti-block, foreign-language monitors, more classifiers) is in my stash — this is the working core. > **💡 Why a brand actually pays $200–2,000 for this** > > - A shoe brand wants to know the _second_ a competitor drops a price or a “sale” banner — you catch it off their sitemap in 15 min, they’d never sit refreshing 40 sites. > - A recruiter watches 200 company career pages; every new senior-role posting = a lead worth more than your whole monthly fee. > - A crypto/stocks desk wants tone flips across 500 news sources classified “bullish/bearish” before it hits mainstream. > - A law/compliance team needs “did any of these 1,000 gov pages change a rule” — miss one and it’s a fine, so your report is cheap insurance. > - An Amazon seller watches competitors’ listings for stock-outs — the hour a rival goes out of stock is the hour they raise prices. > > Same engine every time. You just swap the site list and the labels. The cloud can _answer_ questions. It can’t _watch_ for you — that’s the gap you’re renting out. 👁 ---

@Ze380y @SRZ … thanks for the response… is this also a similar process with the crypto wallet cluster analysis? ---

@scarywiteghost yeah — **same skeleton, different shape.** Same rule as before: the data’s free, and the T4 only does the one heavy step. But you don’t _scrape_ anything here — the blockchain is already public and fully indexed, so “getting the data” is a free download, not a crawl. And a secret they don’t tell you: **most of the clustering is old-school detective math, not AI.** The GPU model is just the accuracy layer bolted on top. Boxes below 👇 > **🪙 The shape of it — why this isn't the same as the site monitor** > > The monitor was _watch forever, classify in bursts_. This one is _per-case, batch_: > > 1. **Pull** — grab an address’s full transaction history. Free — the chain’s already public: [AWS public blockchain dumps](https://registry.opendata.aws/aws-public-blockchain/) (no login), [Blockchair per-address dumps](https://blockchair.com/dumps), or free RPC via [dRPC Chainlist](https://drpc.org/chainlist). No scraping, no getting blocked. > 2. **Cluster with heuristics (no GPU)** — plain rules group addresses that obviously share one owner. This alone gets you ~70% of the way. > 3. **Refine with the GNN (the only T4 part)** — train a graph model on top to catch the wallets the rules miss. This is the accuracy that turns a $50 job into a $5,000 one. > 4. **Attribute + report** — match clusters to known names (exchanges, scams, sanctioned wallets) → hand the client a case file. > > So: same “free data + GPU only for the hard bit” engine, but it’s a batch investigation, not a 24/7 stream. > **🕵️ The old-school math that does 70% before any AI touches it** > > This is the part nobody spells out — the core clustering is 2013-era heuristics, zero GPU: > > - **Common-input-ownership** — if two addresses are spent _together_ in one transaction, the same person owns both. That one rule collapses thousands of addresses into a single wallet. > - **Change-address detection** — when you pay someone, the “leftover” comes back to a fresh address you also own. Spot it, add it to the cluster. > - **Deposit-address reuse** — everyone who sends to the same exchange deposit address is linkable. > - **Peel chains** — follow a big wallet “peeling” off small amounts hop by hop to trace where funds actually went. > > Don’t code these from scratch — they’re already written: > > - Bitcoin: [bitcoin-address-clustering](https://github.com/VincenzoImp/bitcoin-address-clustering) stacks 7 heuristics in one repo; [BitIodine](https://github.com/mikispag/bitiodine) does it in fast Rust. > - Ethereum (different — account model, not coins): [etherclust](https://github.com/etherclust/etherclust) does deposit-reuse + airdrop + token-approval clustering. > - Following the money for a client: [RustyTaintChain](https://github.com/TaintChain/RustyTaintChain) traces tainted funds with the FIFO method lawyers actually accept in court. > > Run these first. The GNN only exists to clean up what they miss — build it the wrong way round and you’re burning GPU to relearn free rules. > **🧠 The T4 part — training a graph model on a transaction graph** > > Wallets = dots, transactions = lines between them. You train a **graph neural network** to spot which dots belong together: > > - Libraries: [PyTorch Geometric](https://github.com/pyg-team/pytorch_geometric) and [DGL](https://github.com/dmlc/dgl) — the two standard graph-ML toolkits, both run fine on a T4. > - “My graph is too big for a free GPU” — it isn’t. Neighbor-sampling (GraphSAGE) or [GNNAutoScale](https://github.com/rusty1s/pyg_autoscale) keep GPU memory _constant_ at any graph size, so a billion-edge chain still fits. That’s the exact trick that makes the free T4 enough. > - The smart split: use the GNN just to turn each wallet into a number-vector, then a plain CPU model does the final call — see [Inspection-L](https://arxiv.org/abs/2203.10465). Lighter, and often better. For fraudsters actively hiding, [CARE-GNN](https://github.com/YingtongDou/CARE-GNN) is built for exactly that. > - Free ready-made training graphs to practice on: [Elliptic++](https://github.com/git-disl/EllipticPlusPlus) (822k labeled BTC addresses) and CN academic [XBlock](http://xblock.pro/#/dataset). > **🏷️ What actually turns a cluster into a NAME (and the paycheck)** > > A cluster is just “these 400 addresses = one owner.” The money is naming that owner. You enrich with public label sets: > > - Sanctions: [auto-updated OFAC crypto address list](https://github.com/0xB10C/ofac-sanctioned-digital-currency-addresses) — instant “this cluster touched a blacklisted wallet” report. > - Names + scams: [eth-labels](https://github.com/dawsbot/eth-labels) (169k labeled addresses), [GraphSense TagPacks](https://github.com/graphsense/graphsense-tagpacks) (500k open tags), live [scamsniffer drainer list](https://github.com/scamsniffer/scam-database). > - Sometimes the owner literally named their own wallet (ENS / on-chain labels). > - Whole self-hostable clustering-to-UI app already built: [Tutela](https://github.com/pareto-xyz/tutela-app). > > Full rare stash (foreign-language deanon tradecraft, more datasets, report tools) is in my collection — this is the working skeleton. > **💸 Who pays $500–5,000 for a cluster, and why** > > - Someone got rug-pulled for $80k — an asset-recovery firm pays you to trace where it landed (which exchange), so lawyers can subpoena a real name. > - A divorce/fraud case where one side hid money on-chain — the investigator needs the hidden wallets mapped. > - A DAO/protocol got drained — they pay to follow the peel chain before the hacker cashes out. > - A VC doing due diligence wants to know if a founder’s “treasury” is really 5 wallets they secretly control. > - OSINT shops resell the same cluster as a report to 3 different clients — you built it once. > > Same engine every case. You swap the starting address and the label set. Cash hides behind a new face each hop; the chain remembers every one of them — you just teach the machine to connect the dots. 🔗 ---
