EDIENPOL (EPOL)
Real-Yield DeFi Protocol

1. Problem Statement

1.1 Fundamental Problems in DeFi

Most projects in today's DeFi market share the following problems:

1) Unsustainable Tokenomics

• Ponzi structures that depend solely on new investor inflows
• No link to the real economy
• Price collapses driven by team sell pressure

2) Phantom Yields

• Unsustainably high APYs that trading fees alone cannot support
• Self-burned tokens presented as "revenue"
• No mechanism that generates real external revenue

3) Whale Manipulation

• Price manipulation by whales deploying large capital
• Trading practices that induce liquidations of retail investors
• Market fairness issues

4) No Real Economy Connection

• Only purely virtual assets exist
• No real business model, so no external revenue
• No investor protection mechanism

1.2 Problems Faced by Retail Investors and Real-World Services

1) Structural losses for retail investors

• Emotions are hard to beat: people sell in fear and buy in greed
• Markets never sleep: prices move 24 hours a day, even while you sleep
• One collapse wipes everything out: a single large loss erases accumulated gains
• It is not a matter of skill — there is simply no mechanism that enforces the rules

2) Trust problems with existing auto-trading services

• Custody risk: assets and API keys must be handed to a company, exposing users to withdrawal and hacking risk
• Opaque performance: results rely on screenshots and self-reporting and cannot be verified
• Misaligned value: monthly subscription models charge users regardless of their profit or loss

3) Reward points and walking data are cut off from value

• App points can only be used inside the issuer and do not carry external value
• The value of walking and gait data generated every day does not return to users
• Smartphone-based step counts are easy to fake and lack hardware-level verification

1.3 EPOL's Solution

EPOL addresses these problems in four core ways:

1. Real Cash Flow Integration: SNP-BOT performance fees and Walkdoni ecosystem revenue are wired into the buyback engine
2. Dual Token System: Clear separation of roles between a utility token (EPOL) and a value token (WBEDR)
3. Non-Custodial & Proof-of-Performance: Assets stay in the user's own account; performance is recorded on-chain
4. Anti-Whale Mechanisms: Dynamic tax rates and multi-hop checks prevent market manipulation

2. Solution: A Real-Yield DeFi Platform

2.1 What Is the Real-Yield Model?

Real Yield means returns that come from actual revenue outside the protocol, not from new token issuance (inflation). EPOL connects two real cash flows — AI trading performance fees and healthcare and commerce revenue — to buybacks and dividends executed by smart contracts.

Core value proposition:

• Transparency: every trade, performance record and revenue distribution is recorded on the blockchain
• Automation: smart contracts execute buybacks and revenue distribution automatically
• Accessibility: users worldwide join the ecosystem through everyday activities — walking and trading
• Efficiency: removing intermediaries reduces costs

2.2 EPOL's Three-Layer Architecture

┌─────────────────────────────────────────────┐
│  Layer 3: DeFi Protocol (Smart Contracts)   │
│  DEX / Farm / Vault / AntiWhale / Burn Game │
└─────────────────────────────────────────────┘
                      ↓
┌─────────────────────────────────────────────┐
│  Layer 2: Tokenomics                        │
│  EPOL utility + WBEDR value token           │
└─────────────────────────────────────────────┘
                      ↓
┌─────────────────────────────────────────────┐
│  Layer 1: Real Economy (Real Revenue)       │
│  SNP-BOT fees + Walkdoni revenue & data     │
└─────────────────────────────────────────────┘

Each layer delivers value to the layer above it, and cash flow from real-world services becomes the revenue source of the DeFi protocol.

3. Business Architecture: The Alliance Structure

3.1 Overview

The EPOL ecosystem is run as a two-way settlement alliance of independent entities, each with its own strengths, connected by business agreements (BA). The design isolates regulatory and securities risk by entity and secures accounting transparency.

The X% in ① and the governing law in ⑩ will be set once both foundations' legal domiciles and corporate forms are finalized.

4. Core Partner Services

4.1 SNP-BOT: AI Quant Trading

SNP-BOT is an AI trading bot whose quant algorithm trades on the user's behalf. Assets stay in the user's own exchange account; the bot only places orders.

How trades are executed:

1. Market watch    → checks prices 24 hours a day
2. Signal analysis → judges the trend with 9 indicators
3. Risk filter     → holds off entry if conditions are not met
4. Order execution → executes in the user's own exchange account

The bot enters only when the trend is statistically favorable and blocks unnecessary over-trading, trading 1–3 times a day. Take-profit and stop-loss levels are set before entry; verified rules, not emotions, decide each trade.

Trading algorithm (9 indicators):

Entry and exit rules:

Leverage notice: this strategy uses positions of up to about 10× account equity. As profit opportunities grow, so does the size of potential losses.

Stable series (A–E):

Higher versions raise both expected return and risk of loss in the same proportion. The figures above are targets and are not guaranteed.

Three safeguards:

1. No withdrawal permission: Exchange API keys grant order permission only, never withdrawal permission
2. Whitelisted servers only: Access from anything other than registered servers is blocked
3. Stop-loss always on: If the market moves against the analysis, the stop-loss triggers

The company neither holds custody of participants' assets nor can it withdraw them. Participants can review every trade themselves and disconnect at any time.

Operating environment:

• Supported exchanges: connect the API of your chosen exchange among Binance · Bitget · Bybit · XT · Huobi · OKX
• Instruments: limited to 5 top market-cap majors such as BTC · ETH · SOL (no indiscriminate altcoin trading)
• Limiting exchanges and instruments to majors reduces liquidity risk

Live trading records:

These figures are live trading records for specific periods and do not guarantee the same results in the future. Principal loss may occur depending on market conditions, and returns from specific past periods are never annualized or compounded.

Fees and settlement:

• Bot fee: completely free
• Profit settlement: only the net profit the bot generates is split 50:50 between the user and SNP-BOT
• Settlement deposit: USDT is pre-deposited for settlement; the bot stops automatically if the balance runs short
• Loss periods: realized profits are also counted as principal, and no settlement fee or other cost applies until principal is recovered

Four steps to join: Install the app → open an exchange account and register an API key → deposit assets into your own account → choose a version and instrument and start

EPOL integration design (Trust Architecture):

• Non-custodial vault: The vault contract only grants trade approval to the router; principal can be withdrawn only with the user's own signature. Transfers of principal by the operator are blocked at the contract level
• Proof-of-Performance: At every settlement cycle an oracle signs realized PnL, NAV and fees, and a Merkle root is anchored on-chain so anyone can re-verify. A verification game (WBEDR deposits · challenges) keeps the data trustworthy
• Performance fee → buyback engine: A fixed share of SNP-BOT performance fees is received in USDT (EPOL accepted) and used to fund the Real-Yield Buyback Engine
• CEX integration strategies are protected with MPC, sub-accounts and whitelist locks

4.2 Walkdoni: Smart Shoes That Turn Steps into Assets

Walkdoni is a Move-to-Earn platform that combines IoT and blockchain with the spring-shoe technology Noitaboni Co., Ltd. has built over 25 years. The smart shoe verifies real steps and turns them into data, and those steps lead to WDP points and EPOL.

Core patents:

• Patent No. 10-2240391: System for accruing and using coins through customized shoes
• Patent No. 10-2264796: Technology that provides users with health-based correction information using pedestrian gait data

EdgeAI IoT smart shoes — every shoe becomes a miner:

• Any Shoe, Any Time: Nike, Adidas or dress shoes — attach the Walkdoni IoT module and the shoe becomes a miner
• Proof of Walking: Just walk, and Walkdoni verifies that the steps are real (hardware-verified gait data, PoM)
• Portable Asset: Change shoes and your assets follow you

5th-generation 6-axis AI-IoT chip:

Walkdoni global app (M2E):

• Walk 5,000 or 10,000 steps a day and tokens are mined
• Supports Korean, English, Chinese, Japanese, Russian and German
• Attendance roulette, a dedicated Walkdoni wallet, free 5,000-step rewards twice a day, Doni Friends growth, NFT shoe collecting, workout history

WDP points and the Walkdoni Mall:

• 1 WDP = KRW 500 (adjusted according to market conditions)
• Earn by walking, spend right away at the Walkdoni Mall
• Walkdoni Mall payment: combined payment of 50% WDP + 50% cash
• Payment example: one box of Jeonggwanjang Red Ginseng Daily Sticks — price KRW 70,000 − discount KRW 10,000 − WDP 25,000 = KRW 35,000 paid
• Expanding the catalog: food products from listed company Wooyang Chef Story, well-known brands, more categories such as food, stronger WDP combined payment

Mobile stores that come to you (Smart Office Car):

• Mobile stores that travel nationwide to meet customers in person
• One car per 50,000 residents, up to 1,004 cars nationwide (e.g., Daegu, population 2.37 million → up to 47 cars)
• Distributed regional placement prevents over-competition
• Business automation: online digital marketing → free consultation requests → customer information passed to the Smart Office Car owner → on-site tailored consultation

New revenue from walking data (healthcare DePIN):

• Revenue model: monthly subscriptions + data marketplace (insurance · healthcare · local government B2B/B2G)
• Acquisition channels: global fandom IP (HYBE license) + a nationwide mobile dealer network
• Technology assets: 25 years of manufacturing capability · 22 global patents · EdgeAI IoT module

4.3 EPOL × Walkdoni Integration: An Ecosystem Where Walking Becomes an Asset

Both strengths meet at one point: walking becomes value you can use across the ecosystem.

Ecosystem flow:

Walk (the smart shoe verifies each step)
    ↓
Earn WDP (1 WDP = KRW 500, adjusted to market conditions)
    ├──→ Shop at the Walkdoni Mall (50% WDP + 50% cash)
    │
    └──⇄ Exchange for EPOL (WDP ⇄ EPOL in the Walkdoni app)
              ↓
         Trade on the EPOL DEX and exchanges

WDP is a point and EPOL is a token. The two can be exchanged for each other in the Walkdoni app.

Users of both companies meet and grow together:

The WDP ⇄ EPOL exchange links the two user bases, so the users grow together and both companies grow together.

EPOL integration structure:

Trading's PoP (Proof-of-Performance) and walking's PoM (Proof-of-Movement) are verified real-world data economies that share the same EPOL settlement layer.

Three-stage expansion plan:

1. EPOL airdrop: activate user wallets and acquire new wallets
2. WDP ⇄ EPOL exchange enabled: make points and tokens mutually exchangeable
3. Pursue a Binance listing: expand to global exchanges after reaching 100,000 users (target: 100,000 users)

4.4 WWP Wallet: The Dedicated EPOL Wallet

WWP Wallet is a dedicated EPOL wallet designed around simplicity and purpose.

• Easy asset management: store and check EPOL tokens on a single screen
• Simple transfers: send and receive with just a wallet address
• Dual security: account protected with Google OTP and a 6-digit PIN; withdrawals require email and OTP verification
• Install: search "WWP" on the Google Play Store

5. Tokenomics: The Dual Token System

5.1 EPOL Token (Utility Token)

Basic information:

• Token name: EPOL (EDIENPOL)
• Network: Polygon Mainnet
• Contract: 0xbB9b67A2b5E5858B476Db55358e4824DBe61f6DA
• Total supply: 50,000,000,000 (50 billion)
• Decimals: 18
• Standard: ERC-20

Initial token allocation:

EPOL utility:

1. Governance: EPOL holders vote on protocol upgrades
2. DEX fee revenue: the protocol share (0.05%) of the trading fee (0.3%) funds the buyback engine
3. Walkdoni ecosystem exchange and payment: WDP ⇄ EPOL exchange in the Walkdoni app, spending at the Walkdoni Mall
4. SNP-BOT settlement: currency for receiving and settling performance fees (USDT preferred, EPOL accepted)
5. Staking rewards: EPOL rewards for staking LP tokens in farming pools
6. Games: EPOL-burning content such as Heroes of EPOL and Last Man Standing

5.2 WBEDR Token (Value Token)

Concept: If EPOL is the ecosystem's fuel, WBEDR is the token to which value accrues. WBEDR is an already-issued token, not a new issuance, and has been redesigned around utility expansion and value accrual.

Basic information:

• Token name: WBEDR (Wrapped BEDR)
• Network · standard: Polygon · ERC-20
• Contract: 0x6C15dfB5c033283bdE9df131Cec9EfF0D5E610aa
• Total supply: 1,000,000,000 (1 billion) — fully issued, no further minting
• Current pair: WBEDR / EPOL (0x147a6f055Ba876cbdC4246D2DAfEeA9372a3cAF8) — trading on the EPOL DEX
• Initial reference: 1 WBEDR = 1,000 EPOL (bootstrap reference ratio)

WBEDR utility and rights:

1. Tier access: staking size determines engine access and dividend weighting
2. Verification-game collateral: used as collateral when challenging performance data
3. Fee discounts: discounts on ecosystem service fees
4. Dividends · veWBEDR · buyback benefits: receive the dividend share of buyback-engine allocations, weighted for locked veWBEDR
5. Disclosure principle: arithmetic FDV may not be used externally before an effective market forms

Staking tier structure (inherits the BEDR membership system):

Exact figures will be set once circulating supply and the target staking ratio are finalized; veWBEDR lock-based dividend weighting is subject to prior legal review.

Price anchor design — from a fixed ratio to a revenue anchor:

The bootstrap fix is released step by step only after the SNP real-revenue buyback (revenue anchor) is running, and every transition is gate-based rather than date-based.

• Safeguards: raised only after gates are met for N consecutive days, automatic rollback if missed, 48-hour advance notice, anti-whale, liquidity lock, circuit breaker

5.3 The Token Economy's Virtuous Cycle

[Revenue stream 1] DEX trading fees
[Revenue stream 2] SNP-BOT performance fees  (TVL × net return × fee rate)
[Revenue stream 3] Walkdoni revenue          (subscriptions · data · commerce)
        ↓
Real-Yield Buyback Engine
  Weekly TWAP buyback — market purchases funded by USDT · EPOL receipts
        ↓
  ├─ A. Holder dividends  60%
  ├─ B. Permanent burn    30%  (lower circulation · scarcity)
  └─ C. DAO treasury      10%  (development · liquidity)
        ↓
Higher staking returns · higher farming APY
        ↓
More Walkdoni users · more SNP-BOT users
More WDP ⇄ EPOL exchange and payment demand
More liquidity · more trading volume

The allocation ratio (60/30/10) is a proposed initial value to be finalized in contract and legal review. Fees are not received directly in WBEDR to avoid volatility spikes while liquidity is thin.

6. DeFi Protocol Architecture

The contract addresses and parameters in this chapter are on-chain values read from Polygon mainnet as of October 3, 2026. The full address list is in 7.1.

6.1 DEX (Decentralized Exchange)

Overview: The EPOL DEX is a decentralized exchange based on the automated market maker (AMM) model, forked from Uniswap V2.

Core features:

1. Automated liquidity (AMM)
   • Formula: x × y = k (constant product)
   • Liquidity providers deposit two tokens in equal value
   • Traders swap tokens against the deposited pools
2. Main trading pairs
   • EPOL / USDT — main liquidity pool (Farm PID 0)
   • wBEDR / EPOL — value-token pool (Farm PID 4)
   • BEDR / WPOL, BEDR / USDT — BEDR trading pools
   • Additional pairs can be created through community proposals
3. Trading fees
   • 0.30% swap fee (Uniswap V2 standard)
   • 0.25%: accrues to liquidity providers (LPs)
   • 0.05%: protocol fee (Factory feeTo enabled, accrues to the treasury)
4. Pricing
   • Real-time price queries via Polygon RPC
   • Slippage calculation and user protection
   • User confirmation required for high price impact

Smart contracts:

• Factory: 0x275503aC956295042b0E57f73Bb8a8200a7f0524
• Router: 0x0F6093ab38b8DABF5c24Bb78Aa8D78B4E5A6C0de

6.2 MasterChef-Style Farming (Yield Farming)

Overview: EpolFarm (MasterChef-style) lets users stake Uniswap V2 LP tokens to earn EPOL rewards.

Active pools (PID):

PIDs 1–3 are pre-relaunch pools with an allocation of 0 and pay no rewards. The total allocation is 100.

Reward distribution:

• 0.011574 EPOL per block (about 2 seconds), roughly $500 per day at EPOL = $1
• Distributed according to each pool's allocation points (currently 50:50)
• Emission is adjusted by a keeper along a price-linked curve
• Users can harvest rewards at any time

Smart contract:

• EpolFarm: 0x7B3169684aB8c0f65AA3db45cfd5891A7b4f57BE

6.3 ERC-4626 Auto-Compounding Vaults

Concept: The auto-compounding vaults implement the ERC-4626 standard. Once a user deposits, the vault repeats the following automatically:

1. Harvest farming rewards (keeper bot)
2. Swap rewards → pair tokens
3. Deduct swap fees
4. Re-add liquidity to the pool
5. Re-stake the resulting LP tokens

Live vaults:

Features:

1. Auto-compounding
   • A keeper bot runs it periodically
   • No user action required
2. Risk management
   • Slippage limit
   • Minimum harvest threshold
   • Panic function to recover funds in an emergency
3. Locked vaults
   • Long-term boost rewards for 6-month locked deposits
   • LockBonusVault: 0x077D38e6BcCb8AdF0dDF76E0b673A0671F8B3f9a

ERC-4626 standard:

• deposit(uint256 assets, address receiver): deposit assets
• mint(uint256 shares, address receiver): mint shares
• withdraw(uint256 assets, address receiver, address owner): withdraw assets
• redeem(uint256 shares, address receiver, address owner): redeem shares
• totalAssets(): total assets in the vault
• convertToShares(): asset → share conversion rate

6.4 Anti-Whale Router V2

Purpose: A dynamic tax mechanism that prevents price manipulation through large trades and the liquidation of retail investors.

How it works:

1. Measuring trade size
   • Trade size is calculated as a share (BPS) of pool liquidity
   • Multi-hop routes check every hop and use the maximum
2. Tiered tax rates (on-chain settings)

3. Defense Mode
   • When large sells of the protected token occur consecutively, the sell limit is tightened step by step (1% → 0.2% → 0.05%)
   • It is released automatically when normal trading resumes
4. Governance protection
   • Changes to the maximum trade size, tax tiers and recipient wallet take effect only after a timelock
   • Tier taxes cannot exceed the contract cap (10%)

Smart contract:

• AntiWhaleRouter V2: 0xD6213Cdc971Aa17A4B9A9519dF789d528FEb2B17

6.5 Burn Game (Last Man Standing)

Concept: Last Man Standing is an on-chain game played with EPOL. Part of every entry is permanently burned, reducing EPOL supply.

Game rules:

1. How to play
   • Each EPOL entry restarts the round timer (default 1 hour)
   • If no one else enters before the timer runs out, the last participant receives the prize pool
   • Minimum entry: 1 EPOL (rises step by step as the round progresses)
2. Entry allocation (on-chain settings)

3. Settlement
   • Anyone can trigger settlement after the round ends, and the prize is paid to the last participant
   • Every round record and burn can be verified on-chain

Smart contract:

• EpolBurnGame V3: 0x6865c2A53E404E843aa681A2ba0255BBe36B2Ee0

6.6 Heroes of EPOL (On-Chain Boss Raid)

Concept: Heroes of EPOL is an on-chain raid game in which players attack a boss with EPOL and share the rewards. Boss health and rewards are calculated from the EPOL/USDT TWAP price, reducing the impact of short-term price manipulation.

Smart contracts:

• HeroesBossRaid V2: 0xABf3523C8e49067e257696Fb538dB29e64C4b263
• HeroesTreasureChest V2: 0x4818405c8C0eb28421C6Ac72c3dA2B603A0c3395
• HeroesTwapOracle: 0x7e7FF032a28784cC63E3792714f5B1f5809aacbd

6.7 Quest and Point System

Concept: Completing quests earns EPOL Points, which can be used to buy farming boosts. Referral relationships are recorded in an on-chain registry.

Smart contracts:

• EpolPoint: 0x23c4e8d4849fd6150baa90d2e3fa26de0b777550
• QuestRegistry: 0x4f3f892d016dd887de78545d030a4d8b5ffe44e6
• QuestVault: 0x4afff5df6be5f6f1f7ffd3ceb5fb47226bcf8ac9
• ReferralRegistry: 0x9426b97bfa783ba18c25a1701aa3ee3537135fec
• BoostShop: 0x8462ac65aa31e9f8b975afec4008bdafb7355443
• EpolFarmBoosted: 0xe1a52f832a04671402d81fc8f1b9cbb1816d166b

• Scope: EpolVault.sol, EpolStrategy.sol, EpolLockedVault.sol, AntiWhaleRouter.sol
• Method: automated tools + manual code review
• Result: 2 CRITICAL (all resolved), 7 HIGH (5 resolved, 2 acknowledged)

Findings summary:

Key fixes:

1. CRITICAL-1: ERC-4626 inflation attack
   • Issue: attack vector against the first depositor
   • Fix: virtual share offset (1e6) added via _decimalsOffset()
   • Effect: raises the attack cost by 1e6×, making it economically infeasible
2. CRITICAL-2: setStrategy() reentrancy
   • Issue: state not updated before the external call (CEI pattern violation)
   • Fix: added the nonReentrant modifier and reordered state updates
   • Effect: reentrancy attacks fully blocked
3. HIGH-3: AntiWhale multi-hop bypass
   • Issue: only the first and last token pairs were checked (bypass via intermediate hops)
   • Fix: implemented _computeTaxMultiHop, which checks liquidity on every hop
   • Effect: multi-hop bypass attacks blocked

Audit report:

• Public link: https://edien-pol.com/audit
• All contracts are verified on PolygonScan

8. Revenue Model and Distribution

8.1 Revenue Sources

EPOL generates sustainable Real Yield through three revenue streams:

1) DEX trading fees (Fee-Based Income)

User trade
    ↓
Swap fee: 0.30%
    ├─ 0.25%: accrues to liquidity providers (LPs)
    └─ 0.05%: protocol fee (treasury → buyback engine funding)

Formula example (assumption): monthly volume of 10M USDT
→ Total fees: 30,000 USDT
→ Protocol revenue: 5,000 USDT/month

2) SNP-BOT trading performance fees (Performance Fee Income)

SNP-BOT trades in the user's own account
    ↓
Only when net profit is made: user : SNP-BOT = 50 : 50
(no bot fee · no settlement before principal is recovered)
    ↓
A fixed X% of SNP-BOT revenue is transferred to the buyback engine
(USDT preferred · EPOL accepted)
    ↓
Weekly TWAP buyback → dividends · burn · treasury

SNP contribution R = TVL × net return × fee rate × allocation share

3) Walkdoni ecosystem revenue (Healthcare DePIN & Commerce Income)

Verified walking data · WDP economy · Walkdoni Mall
    ↓
Monthly subscriptions + data marketplace (insurance · healthcare · local government B2B/B2G)
Point settlement · marketplace payments (USDT · EPOL based)
    ↓
Joins the WBEDR engine — contributes to buyback funding as the third revenue stream

8.2 Revenue Distribution

DEX trading fee distribution:

Real-Yield Buyback Engine design values (proposed initial values):

Buyback engine allocation:

SNP-BOT performance fees + Walkdoni revenue + DEX protocol revenue
    ↓
Weekly TWAP buyback (market purchases · executed in tranches)
    ↓
    ├─ Holder dividends 60%  → paid to staked WBEDR holders in USDT or WBEDR
    ├─ Permanent burn   30%  → lower circulation · scarcity
    └─ DAO treasury     10%  → development · liquidity

Accounting order: USDT dividend funding and buyback funding are never double-counted; receipts are split by purpose upfront.

8.3 Valuation Framework — Revenue, Not Price

The EPOL ecosystem is valued on actual revenue, not on token price.

Formulas:

• Total staking value = R ÷ Y
• Implied circulating market cap = R ÷ (Y × s)
• SNP contribution R = TVL × net return × fee rate × allocation share

R: annual dividend funding · Y: required yield · s: staking ratio

Example scenario (illustrative assumptions):

The table above is an illustrative assumption to explain the formulas, not a forecast. Annualized compounding of specific past periods and arithmetic FDV are prohibited; values are calculated only from conservative, auditable realized returns. Walkdoni revenue does not borrow partner financial projections and will be reflected once actual results are confirmed.

9. Governance (DAO)

9.1 Governance Model

EPOL adopts a three-stage governance model aimed at progressive decentralization:

Phase 1 (current): Team-led governance

• The team makes key decisions
• Build a community feedback process
• Begin voting on major changes

Phase 2 (Year 2): Hybrid governance

• Equal voting power for the team and community (50:50)
• Major agenda items decided by EPOL token vote
• Off-chain voting via Snapshot

Phase 3 (Years 3–5): Fully decentralized DAO

• Team role reduced to advisor
• All decisions made by DAO vote
• Voting authority distributed through multi-sig wallets

9.2 Voting Rights

Voting power:

Staked WBEDR receives weighted voting power to reflect the voice of participants with real skin in the game through long-term locks. The exact weighting multiplier will be set after legal review.

Voting subjects:

1. Protocol upgrades
   • Adding new features
   • Modifying smart contracts
   • Changing network parameters
2. Financial decisions
   • Budget allocation
   • Adjusting buyback engine allocation ratios
   • Marketing budget
3. Governance policy
   • Changing voting rights
   • Electing the governance council
   • Changing rules

9.3 Governance Council

Composition:

• An appointed initial council (5 members: team + community representatives)
• Annual elections replace 50% of members
• Term: 1 year

Authority:

• Temporary measures in emergencies
• Mediating community disputes
• Overseeing budget execution

Joint partner matters:

• Each alliance foundation operates independently; only joint matters are decided by a joint council (BA clause ⑥)

11. Risk Management

11.1 Technical Risks

1) Smart contract vulnerabilities

Current status:

• Internal security audit completed (CRITICAL 2/2, HIGH 7/7 resolved or acknowledged)
• 72 Foundry tests passing
• Contracts verified on PolygonScan
• External audit scheduled for 2026.Q4
• New buyback and vault contracts: two or more audits + bug bounty + timelock

2) Oracle manipulation

11.2 Market Risks

1) Price volatility

Mitigation:

• Anti-whale router limits extreme trades
• Long-term lock incentives (6-month farming bonus)
• WBEDR price-anchor transitions: automatic rollback and circuit breaker if gates are missed

2) Market share competition

Mitigation:

• Emphasize Real Yield backed by real services (SNP-BOT performance fees · Walkdoni revenue)
• Differentiate through verifiable on-chain Proof-of-Performance (vs. screenshots and self-reporting)
• Technology gap from hardware-verified gait data (PoM) and 22 global patents

3) Regulatory risk

11.3 Business Risks

1) Partner business performance

Mitigation:

• SNP-BOT: state clearly that futures leverage (up to 10×) can cause principal loss and that past performance does not guarantee future returns
• Use only on-chain-verified figures in marketing; prohibit annualized compounding of specific past periods
• Walkdoni: advance to the next stage (listing) only after stage gates such as 100,000 users are met
• Mobile stores are distributed by regional population to prevent over-competition

2) Key personnel departure

Mitigation:

• 4-year vesting of team tokens (30% locked)
• Incentive structure (performance bonuses)
• Backup team

3) Counterparty risk

Mitigation:

• Multi-sig wallets (2-of-3 signatures required)
• Auditable smart contracts
• Quarterly on-chain settlement reports (BA clause ⑧)
• Documented procedure to separate assets and liquidity on termination (BA clause ⑨)

Conclusion

EPOL combines two real cash flows — AI trading and walking — with DeFi to build a true Real Yield ecosystem. The Real-Yield Buyback Engine is designed to be funded by real service revenue rather than new capital inflows, and EPOL has completed a full technology stack (DEX, farming, vaults, anti-whale router, games) and security audits.

SNP-BOT supplies revenue through a non-custodial structure and on-chain proof of performance, and Walkdoni supplies real users and spending through patented smart shoes and the WDP economy. EPOL provides the trading, exchange and settlement infrastructure on top. Building on what each partner does best, EPOL will present a new paradigm for the blockchain industry as a next-generation Real-Yield platform where walking becomes an asset and performance is never hidden.
