Yield Booster

One of the main incentives for staking $CRUIZE for $esCRUIZE is the ability to boost your rewards on the provided liquidity. $esCRUIZE tokens allow you to earn a boost of up to 25x on the yield generated on your provided liquidity.

A total of 10,000,000 $CRUIZE tokens will be reserved each year for these boosted rewards. The protocol will group users into 4 tiers depending on the below ratio,

r=esCRUIZE_heldliquidity_providedr=\frac{esCRUIZE\_held}{liquidity\_provided}

where the multiplier associated with each tier is as follows:

  • rr < 5% will receive a 1x multiplier

  • 5% < rr < 15% will receive a 4x multiplier

  • 15% < rr < 25% will receive 10x multiplier

  • 25% < rr will receive a 25x multiplier

In order to avoid exceeding the 10,000,000 yearly rewards limit, the following constrain must be achieved:

(users_tier_11x)+ (users_tier_24x)  + (users_tier_310x)+ (users_tier_425x) = 10,000,000\begin{gather*} ( users\_tier\_1*1*x)\\ +\ ( users\_tier\_2*4*x)\\ \ \ +\ ( users\_tier\_3*10*x)\\ +\ ( users\_tier\_4*25*x)\\ \ =\ 10,000,000 \end{gather*}

where xx constitutes the base reward rate. Therefore, the amount of returns to be augmented by each tier’s multiplier has to be:

x=10,000,000i=14(users_tier_i * multiplier_i)x=\frac{10,000,000}{\sum_{i=1}^4 (\text{\\users\_tier\_i * multiplier\_i})}

for multiplier_imultiplier\_i = 1, 4, 10, 25 for ii = 1, 2, 3, 4 respectively.

Example

Let’s see this with an example. Let’s suppose the protocol configuration is as follows,

  • TVLTVL = $10,000,000

  • APYAPY = 10%

  • APY_after_protocol_feesAPY\_after\_protocol\_fees = $830,000

  • CRUIZE_priceCRUIZE\_price = $0.3

Let's suppose that we have 4 users with the following percentages of LP provision and staked assets

  • user 1: 10% liquidity_providedliquidity\_provided ; 1% esCRUIZE_heldesCRUIZE\_heldrr = 0.1 ⇒ tier 2

  • user 2: 10% liquidity_providedliquidity\_provided ; 1% esCRUIZE_heldesCRUIZE\_heldrr = 0.1 ⇒ tier 2

  • user 3: 10% liquidity_providedliquidity\_provided ; 1% esCRUIZE_heldesCRUIZE\_heldrr = 0.1 ⇒ tier 2

  • user 4: 70% liquidity_providedliquidity\_provided ; 97% esCRUIZE_heldesCRUIZE\_heldrr = 1.38 ⇒ tier 4

Then the base APY generated on the total value staked by all users is 8.30% and the base reward rate of the APY is given by

x = 10,000,000(34) + (125) = 270,270 \begin{gather*} x\ =\ \frac{10,000,000}{( 3*4) \ +\ ( 1*25)} \ =\ 270,270\\ \end{gather*}

which gives a final total APY of

  • user 1: 8.30% + 4x10%10,000,000\frac{4*x}{10\% * 10,000,000} = 44.3%

  • user 2: 8.30% + 4x10%10,000,000\frac{4*x}{10\% * 10,000,000} = 44.3%

  • user 3: 8.30% + 4x10%10,000,000\frac{4*x}{10\% * 10,000,000} = 44.3%

  • user 4: 8.30% + 25x70%10,000,000\frac{25*x}{70\% * 10,000,000} = 104.83%
