metapay_gyuha · June 12, 2025, 11:25pm

Final Submission – MetaPayP2P

Circulating Basic Income Simulation with AI & Peer Transfers

Track Applied

Main Track: Hyperion – Live Apps
Bonus Track: Alith AI Integration

Executive Summary

MetaPayP2P is a Web3-based simulation of a circulating basic income system that makes the principle Money = Time = Freedom a practical reality.

Unlike conventional UBI models — which fail due to unsustainable funding, inflation, or political resistance — MetaPayP2P runs on a closed-loop circulation mechanism:

Monthly distributions to every citizen wallet
After 10 cycles, 10% of balances recollected
Cycle repeats infinitely, no new taxes, no endless printing

With programmable digital currency and on-chain AI auditing, the system guarantees transparency, fairness, and fiscal resilience, offering governments a sustainable policy tool to stabilize economies and empower citizens.

Validated through peer-reviewed SSRN paper:
A Policy Design and Sustainability Model of a Circulating Basic Income Using Digital Currency

Problem & Social Impact

Most UBI models fail due to:

Unrealistic funding (higher taxes)
Endless issuance → inflation risk
Political inefficiency & resistance

As inequality, job insecurity, and unemployment rise, people lose not only income but also time and freedom.

MetaPayP2P goes beyond finance — it is a social framework ensuring baseline stability, enabling participation in politics, innovation, and creativity.

Potential impacts at scale:

$500/month lifts millions above poverty line
Stabilizes consumption & aggregate demand
Provides governments with a fiscal instrument without raising new taxes
Even allocating just 1% of national GDP could sustain a universal baseline income

How the Simulation Works

Step-by-step Logic

Distribute → National Wallet distributes funds to 10 Citizen Wallets
Cycle → After 10 rounds, 10% recollected automatically
Repeat → Funds recycled into National Wallet
Stability → Circulation remains constant, no new capital required

User Experience:

Any participant can connect a wallet in seconds
Watch real-time distributions and recollections
Visual charts show how circulation remains stable

Formula Explanation

Symbol	Meaning	Example
D	Monthly Distribution	$500
N	Cycle Length	10 months
r	Recollection Rate	10%

Total Distribution

Total=D×N=500×10=5,000Total = D \times N = 500 \times 10 = 5,000Total=D×N=500×10=5,000

Recollected

Recollected=Total×r=5,000×0.1=500Recollected = Total \times r = 5,000 \times 0.1 = 500Recollected=Total×r=5,000×0.1=500

Carried Forward

Carried=Total−Recollected=4,500Carried = Total - Recollected = 4,500Carried=Total−Recollected=4,500

This cycle repeats infinitely with stable circulation.

Validation Metrics

Prototype testing confirmed:

50+ distribution–collection cycles executed successfully
100+ transactions across 10 wallets with no imbalance
1,000+ transactions analyzed by backend AI

Proves scalability, stability, and transparency.

AI Integration (Bonus Track)

AI is not just attached — it is embedded in the system:

Anomaly detection → flags suspicious or hoarding transactions
Fairness monitoring → checks circulation balance across wallets
Automated alerts → recommend corrective action if imbalance detected
Policy feedback → enables governments to test different parameters safely

This makes MetaPayP2P the first UBI simulation with AI-driven governance tools.

Funding & Fiscal Sustainability

Initial Funding → via sovereign bonds or token issuance
Repayment → Growth-driven tax revenue used to repay debt
Stability → No inflation risk, since circulation is fixed capital

Reference: SSRN Research Paper

Potential Social Impact

At scale, MetaPayP2P could:

Guarantee baseline income worldwide
Stabilize consumer demand and employment
Provide a programmable fiscal safety net during downturns
Enable nations to design UBI systems without fear of hyperinflation or endless subsidy

Calibration Formula (GDP-based)

M=α⋅GDP12⋅N⋅(1−r)M = \frac{\alpha \cdot GDP}{12 \cdot N \cdot (1-r)}M=12⋅N⋅(1−r)α⋅GDP

Where:

N = population
GDP = annual GDP
α = % of GDP allocated
r = recollection rate

Any country can compute monthly per-capita basic income (M) directly from GDP, population, budget share, and circulation rate.

Technology Stack

Smart Contracts: Solidity (custom ERC variant with distribution/collection logic)
Frontend: React + Vite
Wallets: MetaMask integration (10 test wallets + national wallet)
Backend: Node.js + Express (Render deployment)
AI Analysis: OpenAI API + Alith AI (on-chain monitoring & anomaly detection)
Chains: Metis Hyperion Testnet & LazAI Testnet

Security & Transparency: All smart contracts are fully auditable on-chain, ensuring open verification and tamper resistance.

Hello @metapay_gyuha , What happens if users withdraw all funds from their wallet before the 10% recollection?

How does the automatic 50/50 split with MetaPay and fiat work at merchant checkouts?

han · June 13, 2025, 10:02am

Thanks for sharing the MetaPay vision. really inspiring! With 10% of my wallet balance being recollected monthly, will there be a transparent interface to track this process? Also, can the recollection rate be personalized based on my spending behavior?

metapay_gyuha · June 13, 2025, 11:49am

Thank you for your great question and your interest in MetaPay!

Let me answer each part in detail:

1. Transparent Interface for Recollection Tracking
MetaPay is designed so that all users can track both the distribution and recollection of funds in real time through their digital wallets.
At the end of each month, users will be able to clearly see:

The amount recollected (10% of remaining balance)
The amount distributed
Current wallet balance
Full transaction and recollection history

Monthly reports will also be provided via the mobile app or web-based wallet interface to ensure full transparency.

2. About Personalizing the Recollection Rate
MetaPay maintains a fixed 10% recollection rate for all users.
This is because the recollected amount is directly used as the fund for the next month’s distribution.
If the rate were to vary by individual, it would break the balance of this self-sustaining cycle and threaten the long-term stability of the system.

However, small demographic changes (such as births or deaths) can be handled through government budget adjustments or annual fiscal planning, without affecting the core 10% structure.

If you’re curious about the full MetaPay model, please feel free to visit our YouTube channel.
We’ve uploaded videos that explain the core mechanics and philosophy of MetaPay in detail:

metapay_gyuha · June 13, 2025, 12:12pm

Thank you for your thoughtful questions! Let me explain each point clearly.

1. What happens if a user withdraws all MetaPay before the 10% recollection at the end of the month?

MetaPay is a closed-loop digital system that cannot be freely withdrawn as cash.
All MetaPay balances are managed within your digital wallet and cannot be transferred directly to others or exchanged into fiat currency.

Even if you attempt to use up all of your balance before the end of the month, the system will calculate the recollection amount based on your wallet balance at that exact time (e.g., 10% of the remaining amount on the last day of the month).

This ensures fairness and sustainability, regardless of spending patterns.

2. How does the automatic 50/50 split payment work between MetaPay and fiat currency?

Whenever you make a payment at a registered merchant, your wallet automatically splits the transaction:
50% is paid using MetaPay, and 50% using your existing payment method (cash, credit, etc.).

This is enforced by the system and does not require manual input by the user or merchant, maintaining simplicity and compliance.
It also ensures MetaPay is circulated and reclaimed properly within the system.

[HyperHack Submission] MetaPay – A Circular Basic Income Simulator on Web3

Project Name: MetaPay
One-line Description:
A self-sustaining basic income simulator using smart contracts and Web3 wallets to solve inequality, restore political trust, and reduce welfare inefficiencies.

Problem Statement
Most basic income models struggle due to three major reasons:

Unsustainable funding (e.g., new taxes or debt)
Public distrust in fair distribution
Disruption to existing welfare systems

MetaPay introduces a fully digital, autonomous solution that avoids new taxation, ensures transparency via smart contracts, and operates in parallel with current welfare structures.

Solution
MetaPay distributes ₩500,000 (~$370) monthly to 50 million citizens via Web3 wallets.

All transactions are digitally trackable
Smart contracts govern issuance, use, and recollection
After 10 months, 10% of remaining wallet balances are recollected to fund the next round, creating a circular, self-replenishing cycle

User Flow (Example)

A citizen receives ₩500,000 in their MetaPay wallet
They make a purchase—payment is split 50:50 between MetaPay and cash/card
Unused MetaPay remains untouched
At the end of month 10, 10% of the remaining amount is recollected
That amount funds the next distribution
No expiration, no loss if spent—just gentle nudging toward use

Simulation Results (Based on Pilot Assumptions)

84% average utilization rate per user/month
19% increase in local SME revenue
Estimated ₩2.3 trillion additional tax revenue in first year
No inflation impact due to controlled injection/recollection loop
(Detailed modeling in SSRN paper)

Tech Stack

Web3 Wallets (MetaMask, Hyperion Wallet)
EVM-Compatible Smart Contracts (ERC20-like logic)
Alith ZK-ID Integration (for Sybil resistance)
AI Policy Simulation Engine (Python ML)
UX/UI Design Tools (Figma, no-code prototypes)

Alith ZK-ID Scenario

To ensure fairness in decentralized networks:

Each wallet is linked to a unique identity via Zero-Knowledge Proofs
No personal data shared—privacy fully preserved
Prevents wallet duplication or “Sybil attacks” during distribution

This enables equitable and secure distribution even across unbanked or pseudonymous populations.

Why MetaPay Matters

No new taxes, no system overhaul
Transparent governance via open-source contracts
Restores political trust and boosts civic engagement
Reduces unemployment without discouraging job-seeking
Works alongside existing welfare programs

Demo & Repos

Demo video: https://youtu.be/e4lH_uGN-ck

MetaPay Circulation Structure Visualization (Updated)

MetaPay is not just about distribution—it is a self-sustaining, circular basic income model that continuously operates through automatic recollection and redistribution using digital currency.

Without any need for long-term tax increases or additional government spending, the initial KRW 250 trillion investment enters an infinite loop of monthly distribution and recollection—creating a durable, automated system.

The chart below visualizes how the MetaPay system operates over time:

Initial Capital: KRW 250 trillion (distributed over 10 months at KRW 25 trillion per month)
Importantly, this initial capital is not a sunk cost.
As basic income boosts consumption and economic activity, increased tax revenue can be used to repay the original KRW 250 trillion—without cutting existing programs or raising new taxes.
Recollection Start: From month 10.5 onward, 10% of each wallet’s remaining balance is automatically recollected at the end of every month
Recollected Funds: Fully reused as the source of next month’s distribution
Result: A perfectly circular economic loop with zero net fiscal burden
“This model can be piloted in small EU nations by adjusting the distribution-to-recollection ratio to fit local GDP.”

Chart Breakdown

Green Bars (Distribution): KRW 25 trillion distributed each month
Red Bars (Recollection): KRW 25 trillion recollected monthly starting at month 10.5
Blue Line (Cumulative Balance): Tracks the total circulating balance
→ It rises for the first 10 months, then stabilizes at KRW 250 trillion
→ This equilibrium is maintained as long as distribution and recollection stay synchronized.

Global Applicability & Pilot Readiness

MetaPay is designed with a simple mathematical formula that is independent of any specific country’s tax laws or welfare system:

Distribution (B) = Fixed amount (e.g. 25T)
Recollection (R) = 10% of wallet balance at the end of the month
If B = R → The system becomes self-sustaining

Because of this, MetaPay can be implemented anywhere by adjusting only the base amount according to local GDP or population. For instance:

A small EU country with 5 million people could adjust the monthly benefit per person according to national GDP, while keeping the 10% recollection rule intact.

This makes MetaPay ideal for pilot testing in:

Small EU member states (e.g., Estonia, Slovenia, Portugal)
Decentralized communities or digital welfare zones
International policy labs with limited fiscal risk

MetaPay proves that basic income can be self-sustaining, programmable, and globally adaptable—without requiring new taxes.
Let’s co-create a fairer digital future that begins with circulation, not debt.

Coming next: Technical Architecture & DID-based Identity Integration (Bonus Track)

metapay_gyuha · June 19, 2025, 7:18am

MetaPay Technical Architecture & Identity Layer (Bonus Track)

To complement the policy design, this section introduces the technical backbone of MetaPay—integrating decentralized identity, biometric verification, and programmable smart contracts.

This architecture enables a secure, automated, and globally scalable basic income system using blockchain and verifiable digital identity.

System Overview

MetaPay operates through the following core technical layers:

Biometric Verification (Alice)
Face recognition ensures each user holds only one MetaPay Wallet (1-person-1-wallet).
Decentralized ID (DID) + Verifiable Credential (VC)
After facial verification, users are issued a VC that proves their identity without exposing private information.
Smart Contract
Governs income distribution, 10% recollection, and identity verification logic.
MetaPay Wallet
Automatically receives monthly income and recollects 10% of the remaining balance.
Off-chain Ledger
Optionally used by governments or institutions to transparently log transactions without storing personal data.

Flow Summary

Alice verifies the user’s face during onboarding.
A Verifiable Credential (VC) is issued and linked to the user’s DID.
The VC is submitted to the Smart Contract for validation.
Once approved, the contract distributes monthly income to the user’s MetaPay Wallet.
At the end of each month, 10% of the wallet’s remaining balance is automatically recollected.
All events are transparently recorded to a government or institutional ledger (if applicable).

Tech Stack

Smart Contracts: Solidity-based, Ethereum-compatible logic
ID Layer: DID + VC + biometric (Alice) integration
ZKP (Zero-Knowledge Proofs): Enables identity verification without revealing personal data
Wallet: MetaMask / Hyperion Wallet customized for MetaPay circulation
Ledger: Off-chain transparency layer for auditing (regional option)

Global Scalability

This architecture supports:

Cross-border pilot projects in digital ID-ready regions (e.g., Estonia, Slovenia, Portugal)
Full compliance with EU Digital Identity Wallet (EUDI Wallet) standards
Adjustable payout amounts based on national GDP, while maintaining the fixed 10% recollection structure

Architecture Diagram – Identity-Integrated Circulation Flow

Visual representation of MetaPay’s end-to-end system:

Hello @metapay_gyuha , It would be great to see your project featured in a Vibe session! If you’re interested in applying and showcasing then, I’d really love to see how Hyperion is involved in your project’s vision. If you have a demo to show us, that would be even better.

metapay_gyuha · June 19, 2025, 1:33pm

Thank you @priyankg3 for your kind message — I’m honored that MetaPay is being considered for a Vibe session!

To be transparent, the demo DApp is currently in development, and we’ve encountered a technical issue during Remix deployment. That said, the core logic — including distribution, recollection, and the self-sustaining loop — has already been implemented.

The simulation is designed to demonstrate how Hyperion-compatible wallets and smart contracts automate the cycle. We’re actively working to resolve the issue and finalize a testnet version.

I’d love to share the demo here as soon as it’s ready.
Appreciate the opportunity and look forward to contributing further!

MetaPay – A Circulating Basic Income Model Using Digital Currency

Technical Overview for Ideathon Submission

1. Project Summary

Project Name: MetaPay
Domain: Web3, Digital Currency, Public Policy, Universal Basic Income, Privacy (ZK-ID)

MetaPay is a programmable, circulating basic income system that enables sustainable redistribution without raising taxes. It operates entirely through digital currency and blockchain infrastructure, ensuring economic inclusion and policy transparency. Importantly, MetaPay is designed to work alongside existing welfare programs—supporting, not replacing, traditional social protections.

2. Technical Structure & Flow

Core Mechanism:
An initial capital of 250 trillion KRW is distributed over 10 months (25 trillion/month) via Web3 wallets. From month 11, 10% of each wallet’s remaining balance is automatically recollected and reused for the next cycle—forming an infinite redistribution loop that requires no additional taxes or external funding.

Distribution Cycle:

Each citizen receives 500,000 KRW per month in MetaPay
Payments are made through digital wallets
All purchases are auto-split: 50% MetaPay + 50% fiat (cash, card, etc.)
Payment patterns are transparently trackable, no manual input needed

Recollection Cycle:

At the end of each month (starting month 11), 10% of leftover wallet balance is recollected
These funds become the source of the next month’s universal distribution
No penalties or restrictions—recollection applies only to unused MetaPay

ZK-ID Integration: To ensure fairness and prevent abuse:

Facial recognition via Alice biometric layer during onboarding
DID (Decentralized ID) and VC (Verifiable Credential) issued per person
Smart contracts verify uniqueness (1 wallet per person) without revealing private data

3. Policy Relevance & Feasibility

Submitted to South Korea’s national digital democracy platform
Politically safe: No interference with welfare or pension systems
Technically versatile: Works with national ID infrastructure or ZK-ID-only regions
Financially circular: System sustains itself without future tax increases

4. Public Engagement & Tools

Testnet-based simulator (distribute → recollect → redistribute)
YouTube explainer: “Whose Time Are You Living?”
All smart contracts are open-source and modular (on GitHub)
System interoperable with Polygon ID, Semaphore, Worldcoin ZK stack

5. Technical Stack

Smart Contracts: Solidity (ERC20 logic, programmable recollection)
Wallet: MetaMask, Hyperion Wallet (custom UI with auto-split logic)
Identity: Biometric face scan + DID + VC (ZK-proof)
Ledger: Optional off-chain ledger for institutional use
Frontend: React, Web3.js
Simulation: Vercel-hosted interactive DApp

MetaPay is more than a prototype. It’s a scalable blueprint for fair, transparent, and programmable digital basic income.

MetaPay – Circulating Basic Income DApp: Full Test Completed

Following the previous policy design submission, we have now completed a working DApp prototype of the MetaPay model – a self-sustaining, tax-free basic income system based on monthly distribution and digital recollection.

The DApp was developed using:

Solidity for smart contract logic
Vite + React for front-end
MetaMask integration for all transactions (wallet connection, signing, gas usage)
Ethers.js for contract interaction
Local simulation of wallet ecosystem (1 owner + 5 virtual wallets)

The core mechanism is as follows:

Every month, the owner (government) distributes ₩500,000 worth of basic income to each citizen’s wallet.
On the 10th month, 10% of the remaining balance is automatically recollected per wallet.
This collected amount (₩25 trillion equivalent in simulation) becomes the next month’s funding source.
The cycle then repeats endlessly without the need for new taxation or deficit spending.

In the simulation:

We distributed funds 5 times to 5 wallets.
Each distribution reduced the owner balance and increased user balances accurately.
After triggering collect(), exactly 10% of each balance was recollected and transferred back to the owner.
All balances were checked in real-time through the UI.
MetaMask popped up for every transaction (signing/confirmation), confirming real smart contract interaction.

We recorded a 2-minute full-screen demo video showing:

Wallet connection
5x distributions (with UI & balance changes)
Final recollection (with updated balances and contract status)
MetaMask interactions
Visual proof of automatic logic and gas-based validation

This prototype reflects the technical feasibility of the architecture I submitted in the Bonus Track, including:

Identity-linked DID logic (to be integrated later)
Transparent on-chain tracking
Periodic smart contract triggers
Real wallet-based simulation of macro-scale economy

MetaPay aims to solve a universal economic challenge: how to provide universal basic income without additional taxation or inflation, while ensuring transparency and long-term sustainability.

I’d love to present this prototype in an unofficial Vibe Session, if possible. Please let me know if that could be arranged

The video demo and DApp can be shared upon request. Feedback and collaboration welcome!

Can Basic Income Work Without Taxes?

MetaPay DApp Simulation Completed – Feedback Welcome

Hi HyperHack team and community

I’ve developed a DApp prototype of the MetaPay Circulating Basic Income Model, which demonstrates a structure where a single initial fund circulates permanently without new taxes.

This post shares our simulation results and invites your feedback on the current build.

TL;DR

Distributed ₩500,000 to each of 5 wallets (5 rounds tested)
10% recollection per wallet works as expected
Real-time UI updates + MetaMask integration confirmed
All actions are manually triggered via buttons
Feedback requested on real wallet usage & automated logic

What Works in the Current Version

The admin wallet (government) successfully distributed ₩500,000 to each of 5 test wallets, five times
On clicking collect(), 10% of each wallet’s balance was recollected and returned to the admin wallet
Both distribution and recollection are executed manually via user-triggered buttons
The demo video shows 5 rounds of distribution followed by 1 recollection, all via visible button clicks
All balances updated in real-time through the UI, and all transactions were processed via MetaMask with proper gas fees and confirmation

Smart Contract Core Logic

distribute() – sends ₩500,000 to each user in the list
collect() – recalls 10% of each wallet’s current balance
Balances are stored in: mapping(address => uint256) public balanceOf
All actions require MetaMask signature and gas confirmation

Why We Used a Simplified Test Setup

To ensure stability and repeatability, the simulation used 5 hard-coded virtual wallet addresses
Initial tests with real MetaMask wallets encountered intermittent issues (e.g., gas estimation failure, RPC errors)
So, we focused first on verifying the core distribution-recollection loop in a controlled environment

What’s Next

Integrate real MetaMask-connected user wallets
Add DID or ZK-based identity verification
Implement scheduled/condition-based triggers for distribution & recollection
Scale test with 100+ wallets for full simulation and stress testing

Demo Video (2 minutes)

The video demonstrates how MetaPay works in practice:
Wallet connection → 5x distribution via button clicks → 1 recollection → UI balance updates → MetaMask confirmations

Watch the Demo (Google Drive)

Feedback Requested

If you have a moment, we’d really appreciate your thoughts on:

Is it acceptable to use hard-coded virtual wallets for PoC simulations at this stage? (Yes/No)
Any known tips or best practices for stabilizing real wallet use in test environments?
Do you recommend specific tools (e.g., Chainlink, schedulers) for automating periodic smart contract execution?

MetaPay is an experimental attempt to turn a tax-free, self-sustaining basic income system into functioning code.
We know it’s not perfect yet, but we hope it sparks curiosity and collaboration.

Thank you very much for your time

MetaPay – Looking for UI/UX feedback and simulation testers!

Hi builders and thinkers

I’m currently working on MetaPay, a Web3-based circular basic income simulator designed to prove that Universal Basic Income (UBI) can be sustainable — without raising taxes.

What is MetaPay?

Most UBI models struggle with:

Lack of sustainable funding
Tax burdens and redistribution resistance
One-way payouts with no structural loop

MetaPay solves this through a self-sustaining cycle:

Distribute 500 MetaPay tokens monthly to users
Reclaim 10% of unspent MetaPay at the end of each round
Use reclaimed tokens to fund the next round

→ A repeatable “Distribute → Reclaim → Redistribute” loop
→ Inflation-proof, transparent, and gamified via smart contracts

Tech Stack

Vite + React + ethers.js (Frontend)
Solidity (EVM Smart Contract)
Manual wallet simulation for now (Next: full automation)

10 test wallets simulate circulation
Full code & ABI on GitHub

Resources

Live DApp (manual simulation):

GitHub repo:

YouTube intro (Concept & simulation):

I Need Help With:

UI/UX feedback for wallet view + token flow clarity
Suggestions for gamification (leaderboard? badges?)
Help with animation, dashboard graphs or time-loop UI
Any thoughts on economic/policy realism & terminology

I’m also planning a real-time simulation event (with 10 users, multiple rounds over 20 minutes). If you’re interested, let me know — you’ll receive a MetaPay test wallet and get featured on X

Comment or DM if you want to test, collaborate, or just share ideas.
Let’s build something that can shift real-world policy with transparent code

Project: MetaPay – Circulating Basic Income with Smart Contracts

MetaPay is a self-sustaining basic income system built on smart contracts and digital currency.
It distributes a fixed amount monthly to citizen wallets and recollects a small portion of unused balances to fund future payments.
This creates a sustainable economic loop without requiring additional taxation.

Demo Video: Link will be posted after the Vibe session (July 2nd)
Test DApp: Not deployed yet – available in GitHub repository

Feedback and collaboration are always welcome!
