Constant Product AMM

AMM formula: x * y = k where x and y are reserves, k is constant. Used in Owna-DEX for pricing.

---

D

DEX (Decentralized Exchange)

Factory (YRTFactory)

Smart contract to create YRT tokens and manage periods.

Fee Recipient

Wallet address that receives swap fees (0.3%) from DEX trading.

Fundraising Period

Period where users can buy/sell YRT tokens. Duration is flexible (input in seconds).

---

G

GAP Period

Period between snapshot and start of next period. Property owner can mint additional tokens during GAP period.

Period 1 ends → Snapshot → [GAP PERIOD] → Period 2 starts
                            ↑
                    Mint allowed here!

Isolated Pricing

Each property has a separate YRT token and pool, so prices don't affect each other.

---

L

Liquidity

Total value of tokens in the pool. Higher liquidity = lower price impact.

Liquidity Provider (LP)

User who provides liquidity to pool by depositing YRT + USDC. Earns 0.3% swap fees.

LP Token

Token received by liquidity provider as proof of ownership. Can be redeemed for underlying tokens + fees.

---

M

Maturity Date

Due date of fundraising period. Snapshot is triggered at maturity date.

OwnaRouter

Smart contract interface for user operations (swap, add/remove liquidity).

---

P

Period

Fundraising & yield distribution cycle. Example: Period 1 (Q1), Period 2 (Q2), etc.

Pool

Liquidity pool in DEX containing YRT + USDC tokens. Each property has its own isolated pool.

Price Impact

Price change caused by swap transaction. Larger swaps = higher price impact.

Property Owner

Series Admin

Property owner address with admin privileges for a specific series.

Series ID

Unique identifier for tokenized property. Example: 1, 2, 3...

Slippage

Difference between expected price and actual execution price. Caused by price movement during transaction.

Slippage Protection

Min/max amounts in swap transactions to protect from excessive slippage.

Snapshot

"Freeze balances" at maturity date to determine yield distribution. Saves holder addresses + balances.

Snapshot Holders

List of addresses that hold tokens at snapshot time. Used for fair yield distribution.

Swap

Exchange one token for another via DEX. Example: Swap USDC for YRT.

Swap Fee

Fee charged on swaps (0.3%). Goes to fee recipient (not LPs in current implementation).

---

T

Total Supply

Total number of YRT tokens that exist for a specific property.

Total Value Locked (TVL)

Total value of all tokens in the pool. Indicator of pool liquidity.

---

U

USDC

USD Coin stablecoin. MockUSDC (testnet) has 18 decimals, real USDC (mainnet) has 6 decimals.

Upkeep

Chainlink Automation job yang runs AutoDistributor contract automatically.

---

Y

Yield

Profit/income from property that is distributed to YRT token holders.

Yield Distribution

Process of distributing yield proportionally to snapshot holders. Handled automatically via AutoDistributor.

YRT (Yield Receipt Token)

ERC20 token representing ownership share in tokenized property. Each property has unique YRT.

YRTFactory

Main smart contract to create YRT tokens and manage multi-period system.

YRTToken

Individual ERC20 token contract for a specific property. Includes snapshot functionality.

Formula Reference

AMM Constant Product

k = x × y (constant)

Where:
- x = Reserve of Token A
- y = Reserve of Token B
- k = Constant product

Price Calculation

Price = Reserve_Stablecoin / Reserve_YRT

Example:
1000 USDC / 1000 YRT = 1 USDC per YRT

Swap Output

Output = (Input × Reserve_Out) / (Reserve_In + Input)

After fee:
Output = (Input × 0.997 × Reserve_Out) / (Reserve_In + Input × 0.997)

Yield Distribution

User_Yield = (User_Balance / Total_Supply) × Total_Yield

Example:
(100 YRT / 1000 YRT) × 10,000 USDC = 1,000 USDC
