Building the Economic Layer of MyZubster: Multichain Payments, Zorgax Pro and Non-Custodial Architecture
MyZubster is evolving from a collection of independent experiments into a connected ecosystem.
During the latest development cycle, we connected several previously separate areas:
Metaverse → Marketplace → Wallet Hub → blockchain payments → Zorgax services
At the same time, we reorganized the project's visual layer to better separate marketplace, AI, storytelling and our exploratory LIFE 2027 direction.
The most important part, however, is not the number of features.
It is the architecture connecting them.
The Core Principle: The Application Is Not the Wallet
When adding cryptocurrency payments to a marketplace, it is tempting to put everything inside the application.
That creates a dangerous boundary.
MyZubster instead follows a non-custodial principle:
Public receiving address → OK
Transaction identifier → OK
Blockchain verification → OK
Private key → NEVER
Seed phrase → NEVER
Wallet signing credentials → NEVER
The application can coordinate a payment without becoming responsible for the cryptographic keys controlling the funds.
That principle became the foundation of our new multichain Wallet Hub.
Connecting the Metaverse Market to Multiple Networks
The MyZubster Marketplace has been extended to support:
ETH
BTC
XMR
TARI
MYZ
BARTER
FREE
The Wallet Hub provides the bridge between marketplace activity and the external blockchain networks.
The architecture looks roughly like this:
MyZubster Metaverse
│
▼
Marketplace
│
▼
Wallet Hub
│
┌────────────┼────────────┐
│ │ │
ETH BTC XMR
│ │ │
└────────────┼────────────┘
│
TARI
The frontend can expose configured public receiving addresses.
It does not receive or store private keys.
The implementation can be inspected here:

The work is now integrated into the main development history.
From Zorgax Assistant to Zorgax Service
Once the payment architecture existed, another question became interesting:
Can Zorgax become a monetizable service?
We started building that foundation as well.
The first catalog introduces three levels:
Zorgax Free
Zorgax Pro
€9.90 / month equivalent
Zorgax Developer
€29.90 / month equivalent
Paid checkout intents are designed around:
ETH
BTC
XMR
TARI
But creating a checkout is deliberately not equivalent to activating a subscription.
That distinction is critical.
Never Trust “I Paid”
Consider a naïve API:
POST /zorgax/activate
{
"paid": true
}
Obviously, that cannot be trusted.
Even providing a transaction hash is insufficient by itself.
The backend needs to establish that the transaction:
exists
+
belongs to the expected network
+
matches the checkout
+
uses the expected destination
+
contains the required amount
+
has sufficient confirmation/finality
+
has not already been consumed
Only then should application state change.
Our target flow therefore becomes:
User selects Zorgax Pro
│
▼
Create checkout intent
│
▼
Generate crypto quote
│
▼
User sends transaction
│
▼
Network-specific verifier
│
▼
Payment VERIFIED
│
▼
Subscription ACTIVE
│
▼
30-day entitlement
│
▼
EXPIRED / RENEW
This is considerably safer than allowing the frontend to decide whether payment succeeded.
Building the Subscription Lifecycle
The Zorgax monetization work now includes a persistent subscription lifecycle.
Internally, the important states are conceptually:
PENDING
│
▼
VERIFIED
│
▼
ACTIVE
│
▼
EXPIRED
Verified paid access receives a defined validity period.
Renewals can extend access from the existing expiration point when the current subscription is still active.
Payment references are also intended to be single-use.
That prevents a valid transaction from being replayed to create multiple entitlements.
The current implementation is being developed here:
PR #812 — Zorgax monetization foundation
One security decision is particularly important:
the client does not receive a public endpoint capable of declaring its own payment verified.
Activation belongs behind a trusted blockchain-verification boundary.
One Interface, Different Blockchain Adapters
ETH, Bitcoin, Monero and Tari cannot simply be treated as identical networks.
They have different transaction models, privacy properties, RPC interfaces and finality considerations.
Instead of forcing all of them into one blockchain-specific implementation, the architecture can use adapters:
Payment Intent
│
▼
Verification Layer
│
┌──────────────┼──────────────┐
│ │ │
BTC verifier XMR verifier ETH verifier
│ │ │
└──────────────┼──────────────┘
│
TARI verifier
│
▼
Normalized Result
│
▼
VERIFIED / REJECTED
The subscription system should not need to understand every detail of Bitcoin or Monero.
It needs a trustworthy normalized result from the corresponding verifier.
This separation also makes testing easier.
The Marketplace Doesn't Move the Money
Another important distinction is between coordination and custody.
MyZubster can coordinate:
product
price
currency
checkout
payment reference
verification
entitlement
without taking responsibility for:
seed storage
private-key storage
transaction signing
wallet recovery
This gives us a cleaner security boundary.
It also means a compromised web application should not automatically imply compromised blockchain private keys.
Connecting Zorgax to the Economic Layer
This creates an interesting relationship between the different parts of MyZubster.
Zorgax is no longer isolated from the rest of the ecosystem.
Conceptually:
MYZUBSTER
│
┌─────────────┼─────────────┐
│ │ │
ZORGAX METAVERSE REAL-WORLD
│ │ EXPLORATION
│ │
PRO SERVICES MARKET
│ │
└──────┬──────┘
│
WALLET HUB
│
┌────────┼────────┐
│ │ │
ETH BTC XMR
│
TARI
This is the beginning of an economic layer rather than simply a cryptocurrency button attached to a website.
Organizing the Visual Architecture Too
Architecture is not limited to source code.
During the same development cycle, we reorganized the MyZubster visual assets into dedicated areas:
docs/
└── visuals/
├── life-2027/
├── market/
├── storytelling/
└── zorgax/
Nine assets covering environmental concepts, AI/permaculture, marketplace entities, Zorgax characters and storytelling were organized and committed to the repository.
The commit is available here:
Commit af8b1dd — Organize MyZubster visual assets for LIFE 2027
This may sound secondary to backend development, but maintaining clear boundaries between technical, narrative and exploratory material becomes increasingly important as an ecosystem grows.
A Note About LIFE 2027
The life-2027 directory represents an exploratory direction, not a claim that MyZubster has an approved or funded LIFE project.
Our intended progression is evidence-driven:
concept
↓
pilot
↓
measurements
↓
KPIs
↓
technical/scientific validation
↓
consortium development
↓
potential proposal
For environmental technology, code alone is not evidence of environmental impact.
Claims around water efficiency, soil conditions or other environmental outcomes ultimately need measurable results and appropriate validation.
Keeping that distinction explicit is part of the project's engineering discipline too.
What Comes Next
The architecture for monetization is taking shape.
The next major challenge is implementing the actual verification adapters.
For example:
Bitcoin
↓
network/Electrum verification
Monero
↓
node/wallet RPC verification
Ethereum
↓
Ethereum RPC verification
Tari
↓
Tari network verification
After that, we can safely connect:
quote
→ checkout
→ transaction
→ verification
→ entitlement
→ Zorgax Pro
→ expiry
→ renewal
without turning MyZubster into a custodial wallet.
That is the boundary we intend to preserve as the system grows.
