Tokenomics


Ticker: $LAY
Decimal: 18
Total Supply: 1,000,000,000

Distribution

Emission

Except for IDO, the tokens will be rewarded gradually.

Liquidity Mining


Deposit Incentive: 30% of Liquidity Minging Emission

Withdraw Incentive: 70% of Liquidity Minging Emission

Incentive Weight

Stablecoins and the native token should be incentivized larger than others.

  • $ASTR: 3x
  • $USDT: 3x
  • $USDC: 3x
  • $WETH: 2x
  • $WBTC: 2x
  • $SDN: 1x
  • $ARSW: 1x

APR

Since it is useless to calculate APR on analysis, we should calculate the emission amounts for each token on both the depositor side and the borrower side. The details are described on the sheet.

Protocol Revenue


Borrow Interest

Calculated with the same way as AAVE does

Aave V2 Borrow Interest Rate

(Borrow Interest) - {Deposit APR without $LAY incentives)} ≒ 1%

Aave V2 Reserve Parameter

Liquidation

Example:

Bob deposits 10 ASTR and borrows 5 ASTR worth of USDC.
If Bob’s Health Factor drops below 1 his loan will be eligible for liquidation.
A liquidator can repay up to 50% of a single borrowed amount = 2.5 ASTR worth of USDC.
In return, the liquidator can claim single collateral which is ASTR (5% bonus).
The liquidator claims 2.5 + 0.125 ASTR for repaying 2.5 ASTR worth of USDC.

Depositing & Earning


Basically, the earning system would be inherited from AAVE.

vToken, which is an original IOU, holders receive continuous earnings that evolve with market conditions based on:

  • The interest rate payment on loans - depositors share the interests paid by borrowers corresponding to the average borrow rate times the utilization rate. The higher the utilization of a reserve the higher the yield for depositors.
  • Flash Loan fees - depositors receive a share of the Flash Loan fees corresponding to 0.09% of the Flash Loan volume.
