Build the
Citadel.
Your Bitcoin economy, one prompt away.
ArxMint generates private Fedimint federations, Cashu mints, Lightning agent rails, and deploys them instantly. Humans and AI agents share the same sovereign infrastructure.
Wallets aren't economies.
Cold storage is step one, not the endgame. Without spending, earning, and trading in Bitcoin, there's no economy — just a savings account reliant on fiat rails.
The Fiat Trap
Earn in fiat from employer
Spend at surveilled merchants
KYC exchange → buy BTC → cold storage forever
The Sovereign Loop
Earn sats from community work — workshops, services, freelance gigs
Private ecash payments to local merchants — they scan a QR, you pay in sats
AI agents earn & spend via L402 parallel rails — automated services that generate sats while you sleep
What changes day to day.
One week living on Bitcoin rails. No exchanges. No banks. No fiat.
Get paid 50,000 sats for a workshop you taught
Coffee costs 3,500 sats — scan the QR, done
Check the cycle dashboard — MVRV says keep stacking
Your agent earned 23,500 sats overnight selling data
Pay your barber in ecash — the loop closes
You already have the hard part.
If you own Bitcoin in cold storage, you've already done the hardest thing — acquiring sound money and taking self-custody. Most people never get that far.
The next step isn't selling it back to fiat. It's building the infrastructure that lets you spend a fraction locally while your savings stay cold. That's what a circular economy is — a spending layer on top of your savings.
From cold storage to spending
Cold storage stays cold
Your hardware wallet, your keys, untouched
Peg in spending sats
Move a small amount into the federation — like cash from a safe
Sats become ecash
Private, instant, untraceable tokens inside your community
Spend locally
Coffee, haircuts, workshops — sats circulate, economy grows
The Sovereign Bridge.
Not another wallet. A private money rail where humans and AI agents share the same infrastructure.
For Humans
Self-custody ecash backed by real BTC. Private transactions inside your community. No surveillance, no KYC, no banks.
- Silent Payments + CoinJoin
- Federated e-cash privacy
- Local merchant directory
For AI Agents
Native Lightning rails via MCP. Agents sell data, buy compute, and transact in sats — no identity, no banks.
- Lightning Agent Kit
- L402 paywalls (pay-per-request)
- MCP server framework
For Communities
Spin a full private economy for your town. One-click Fedimint federation with merchant directory.
- Prompt-driven creation
- Docker one-command deploy
- 0.2% mint fee community income
Infrastructure batteries included.
Privacy by Default
We don't just offer privacy as an option. CoinJoin, Tor routing, and silent payments are hardcoded defaults at the protocol level.
Cycle Architecture
Live MVRV, NUPL, and supply-in-profit alerts built into the operator dashboard.
Containerized Deploy
LND, Cashu, Fedimint, and Aperture. Spun up with a single Docker composition.
The parallel system is being built.
Sound money infrastructure for a parallel voluntary economy. Protection from hacks, overreach, and controls. Not evasion — sovereignty.
