Hot, cold, multi-sig, and enterprise. Configured so your team can actually use them — hardware sold separately.
Software wallets for daily use on Bitcoin or Bitcoin layers like Stacks — mobile or desktop — with encryption and key-management practices your team can follow. Quick transactions and dApp access, settled on Bitcoin.
Hardware devices for offline storage on Bitcoin and layers such as Stacks. Key generation, recovery-phrase backup, and testing for true self-custody. Hardware sold separately.
Multi-signature wallets on Bitcoin or Stacks, requiring multiple approvals for team or DAO security. We set thresholds such as 2-of-3 or 3-of-5. Hardware and software sold separately.
Layered multi-signature for treasury and compliance — nested approvals, time-locks, and role-based access. Built to reduce single-point and insider risk. Hardware and software sold separately.
Build on the layers
Technical work on Stacks, settled on Bitcoin. Already in web3 and looking for consulting rather than a build? See existing web3 businesses.
Convert inventory, intellectual property, or services into tokens on Bitcoin layers such as Stacks — fractional ownership, transfer, and Bitcoin-backed settlement. We run the technical work: brainstorming, token standards, basic compliance checks. We are not financial or legal advisors. Consult qualified professionals for regulatory questions.
Conceptualize and build dApps on Stacks smart contracts — supply-chain tracking, peer-to-peer marketplaces, and other automated processes anchored to Bitcoin. Guidance from idea through deployment, with interfaces people will actually use.
Hardware
Install and configure Umbrel on your hardware for a full Bitcoin node — verify your own transactions, use the app store, and keep remote access secure. Hardware sold separately.
A Lightning Network node on Umbrel for fast, low-cost payments on Bitcoin Layer 2. Channel management, liquidity, and secure remote access. Hardware sold separately.
A full Stacks node on your hardware with Docker — smart contracts on a network tied to Bitcoin. Needs a Bitcoin node to sync; we can use a public one or stand up a local Bitcoin node for independence. Mainnet or testnet.
Booking options
Quick sessions for a single problem, workshops for a team, or a block of hours for a project. We schedule after an intro — not through a cart.
Targeted, on-demand sessions — wallet setups, a quick briefing, or a specific question. No long commitment.
Extended consulting for deeper Bitcoin or Bitcoin-layer work — wallets, strategy, education, and the steps between (not custom development). Unused time carries over and stays valid for 4 months. Usage is scheduled in advance; clients get a unique Google booking link.
Clients with 120 hours or more may apply time toward workshops — larger engagements cover the preparation behind them.

Workshop
A live foundational course on using modern AI tools in real work — how agents, models, and prompts actually fit a business, not a demo reel. Covers AI fundamentals, prompt craft, content and copy, graphics and brand assets, simple apps and automations, bots and agents, security and data hygiene, resources, and Block9 services. For beginners and teams new to building with AI. Participants leave able to create content, graphics, apps, and bots with confidence.

Workshop
A live foundational course: Bitcoin history, blockchain basics, wallets, nodes, miners, security essentials, resources, and Block9 services. For beginners and businesses new to Bitcoin.

Workshop
Advanced Layer 1 Bitcoin — mechanics, constraints, and why its architecture is hard to copy — then Stacks Layer 2: smart contracts, Bitcoin Naming System (BNS), NFTs, DAOs, and how blockchain and AI actually meet.

Workshop
Premium, onsite, USA-only. Combines both Bitcoin courses with a hands-on cold-storage setup on a client-provided Ledger, sending and receiving Bitcoin or sBTC, and optional Stacks BNS name creation. Starts with a 30–60 minute remote discovery call. Includes a fireproof document bag and steel backup wallet. Travel billed separately. Not a developer course.
Workshops support up to 25 participants. AI Basics, Bitcoin Basics, and Bitcoin & Bitcoin Layers are the live presentations; Orange Case is the onsite premium.
