## 1. Executive Summary

JadongPay (JPAY) is a BEP-20 utility token on Binance Smart Chain designed around a single core idea: **holding should pay you**.

Every time someone sells JPAY on PancakeSwap, a 10% tax is collected. Six percent of that goes directly into a reward pool, automatically swapped to USDT and distributed proportionally to all holders above the minimum threshold. One percent feeds a monthly jackpot drawn via Chainlink's verifiable random function — provably fair, on-chain, uncheatable.

The result is a token where long-term holders earn real stablecoin income, where every holder above 500 JPAY is automatically entered in a monthly prize draw, and where the mechanics are fully transparent, audited, and immutable.

**Key figures at a glance:**

| Parameter | Value |
|---|---|
| Blockchain | Binance Smart Chain (BSC) |
| Token standard | BEP-20 |
| Total supply | 5,000,000 JPAY |
| Presale rate | 7,000 JPAY / BNB |
| Listing rate | 1,400 JPAY / BNB |
| Sell tax | 10% (USDT rewards + jackpot + burn) |
| Jackpot frequency | Monthly — Chainlink VRF |
| Smart contract | Immutable — Audited |

## 2. The Problem

The DeFi token space in 2026 is plagued by four recurring failures that destroy investor value:

**Unsustainable yield.** Most reward tokens print their own token as "yield," diluting holders and collapsing in value within weeks. When the new token supply runs out, rewards stop.

**Inactive holders earn nothing.** Epoch-based snapshot systems only reward wallets that recently transacted. Long-term holders who simply hold and do nothing — the most aligned investors — receive zero. This is both unfair and economically backwards.

**Opaque mechanics.** Reward calculations happen in off-chain databases that no one can audit. Token holders have no way to verify their share or predict their income.

**Manipulable randomness.** Lottery and jackpot systems using `block.timestamp` or miner-controlled entropy can be gamed by block producers. Prize draws are not provably fair.

JadongPay was built specifically to solve all four.

---

## 3. The Solution

**Real stablecoin rewards, not printed tokens.**
JPAY rewards are distributed in USDT — a real, liquid, stable asset. No inflation. No new supply. Pure redistribution of sell-side activity.

**Every holder earns continuously.**
JadongPay uses the Dividend-Per-Share (DPS) model, the same architecture powering SushiSwap's reward system. Rewards accrue to your wallet in real time, proportional to your balance, whether you transact or not. Hold 1,000 JPAY and go offline for a year — your rewards are waiting when you come back.

**Everything verifiable on-chain.**
The smart contract is open source, verified on BscScan, and immutable. Every reward calculation follows a deterministic mathematical formula that anyone can verify independently. No black box. No trust required.

**Provably fair jackpot.**
The monthly jackpot uses Chainlink VRF (Verifiable Random Function) — a cryptographic proof that makes it mathematically impossible for anyone, including the team, to predict or influence the outcome. The proof is published on-chain alongside every draw.

---

## 4. The JPAY Token

JPAY is a utility token with three core functions:

**Passive income vehicle.** Holding JPAY above the minimum threshold (1,000 JPAY) entitles you to a proportional share of all USDT rewards collected from sell taxes.

**Jackpot ticket.** Holding 500+ JPAY for 7 consecutive days without selling automatically enters your wallet in the monthly jackpot draw.

**Deflationary asset.** 2% of every sell is permanently burned, reducing total supply over time. As volume grows, the burn accelerates.

### Token mechanics

JPAY applies a **10% tax on sells only** — purchases and wallet-to-wallet transfers are never taxed.

| Tax Component | Rate | Destination |
|---|---|---|
| USDT Rewards | 6.0% | Distributed to holders |
| Monthly Jackpot | 1.0% | Prize pool accumulation |
| Burn | 2.0% | Permanent supply reduction |
| Reserve | 0.5% | Project reserve wallet |
| Marketing | 0.5% | Marketing wallet |
| **Total** | **10.0%** | |

The 6% reward portion and 1% jackpot portion are collected as JPAY in the contract, then swapped to USDT via PancakeSwap (JPAY → WBNB → USDT) when the threshold is reached. All USDT is held in the contract and claimed by holders at will — no forced distribution, no gas overhead on holders.

---

## 5. How Rewards Work

JadongPay uses the **Dividend-Per-Share (DPS)** model. Here is a concrete example:

Suppose the contract has just distributed 1,000 USDT in rewards. The eligible circulating supply is 2,000,000 JPAY.

```
Reward per share = 1,000 USDT / 2,000,000 JPAY = 0.0005 USDT per JPAY
```

If you hold 10,000 JPAY:
```
Your reward = 10,000 × 0.0005 = 5 USDT
```

This calculation happens continuously. Every time rewards are added to the pool, `rewardPerShareStored` increases. The next time your wallet is touched (a buy, sell, or claim), your pending USDT is calculated precisely from the difference.

**Minimum holding to receive rewards:** 1,000 JPAY
**How to claim:** Call `claimRewards()` from any wallet with pending USDT. Gas cost on BSC: typically under $0.01.

The rewards pool is replenished automatically every time someone sells JPAY. The more volume the token generates, the more USDT flows to holders.

---

## 6. The Monthly Jackpot

Every month, a portion of all sell taxes (1%) accumulates in a dedicated USDT prize pool. Once the pool reaches a minimum of 250 USDT and at least 3 eligible wallets exist, a draw is triggered.

**Eligibility requirements:**
- Hold ≥ 500 JPAY
- Have held continuously for ≥ 7 days
- Have not sold any JPAY in the 7 days before the draw

**Prize distribution:**
- 1st place: 50% of the pool
- 2nd place: 30% of the pool
- 3rd place: 20% of the pool

**How winners are selected:**
The team generates a Merkle tree of all eligible wallets off-chain, submits the Merkle root on-chain, then triggers Chainlink VRF to generate 3 cryptographically random numbers. Winners are determined by their index in the eligible list. The entire process — the eligible snapshot, the Merkle root, and the VRF proof — is public and verifiable by anyone.

**Claiming a prize:** Winners receive a Merkle proof and call `claimJackpot()`. The contract verifies the proof and transfers USDT directly to the winner. No intermediary, no delay.

## 7. Tokenomics

### Supply allocation

| Allocation | Tokens | % | Vesting |
|---|---|---|---|
| Presale | 2,500,000 | 50% | 10% at cliff, 90% linear / 12 months |
| Liquidity | 750,000 | 15% | Locked ≥ 1 year |
| Marketing | 500,000 | 10% | 10% at cliff, 90% linear / 12 months |
| Reserve | 500,000 | 10% | 10% at cliff, 90% linear / 12 months |
| Team | 750,000 | 15% | 5% at cliff, 95% linear / 24 months |
| **Total** | **5,000,000** | **100%** | |

All allocations are **proportional to presale results**. If only 50% of the hardcap is raised, all allocations are halved and the surplus is burned. No phantom tokens, no hidden supply.

### Vesting cliff

The cliff activates 2 hours after liquidity is added to PancakeSwap. This brief window prevents immediate sell pressure while ensuring no tokens are locked indefinitely. After the cliff, vesting is linear — predictable and visible on-chain.

### Liquidity

75% of all BNB raised in the presale goes directly to the JPAY/BNB liquidity pool on PancakeSwap V2. Liquidity is locked for a minimum of 1 year via a third-party locking service (PinkLock or UNCX). The lock transaction hash is published publicly.

**Listing price:** 1 BNB = 1,400 JPAY
**Presale price:** 1 BNB = 7,000 JPAY

The 5× ratio between presale and listing price means early participants enter at a significant discount to the initial market price.

## 8. Presale

### Parameters

| Parameter | Value |
|---|---|
| Total tokens for sale | 2,500,000 JPAY (max) |
| Softcap | 500,000 JPAY (~71 BNB) |
| Hardcap | 2,500,000 JPAY (~357 BNB) |
| Rate | 7,000 JPAY per BNB |
| Minimum contribution | 0.01 BNB |
| Maximum contribution | 5 BNB per wallet |
| Refund policy | Full refund if softcap not reached |

### How the presale works

1. Send BNB to the contract during the presale window (minimum 0.01 BNB, maximum 5 BNB per wallet)
2. Tokens are allocated at 7,000 JPAY per BNB
3. Once the presale ends, the team has 24 hours to finalize (timelock security)
4. On finalization, liquidity is created and trading opens on PancakeSwap
5. Wait 2 hours (cliff), then claim your tokens via `claimTokens()`
6. Vesting begins: 10% immediately, the remaining 90% unlocks linearly over 12 months

### Use of funds

| Destination | % of BNB raised |
|---|---|
| PancakeSwap Liquidity | 75% |
| Team & Development | 14% |
| Marketing | 5% |
| Reserve | 5% |
| Operations (gas) | 1% |
