Boost

Governance > $IDLE staking > LPs rewards boost
Liquidity providers for PYTs (or whitelisted pools for Gauges) can boost their $IDLE rewards by holding stkIDLE. The boost can be up to 2.5x the base rewards, based on the amount of stkIDLE holding.
The liquidity providers balance counted in the liquidity gauge is eligible to get boosted (depending on LPs vote weight) if LPs lock/stake their $IDLE (then as a result of this, holding stkIDLE).
Holding stkIDLE gives users more weight when collecting certain farming rewards. Part of the farming rewards that are distributed directly through the protocol is eligible for stkIDLE boosts.
External farming promoted by other external protocols (such as Sushi, Onsen) is typically not available for stkIDLE boosts since it is independent of the Idle protocol itself.
In a given gauge, owning stkIDLE increases a user share of the pool thus increasing the rewards received. Users holding no stkIDLE are anyway considered as providing 100% of their liquidity. If a user owns enough stkIDLE, the user can be considered as bringing up to 250% of its original liquidity (or a 2.5x boost compared to the original 100%).
The 2.5x multiplier in liquidity provided translates into a boost on rewards depending on the total liquidity provided in the pool and how it is considered by the gauge boost calculator.

Boosting formulae

Following the approach of the Angle protocol, we set
liquidityuser=user liquidity in the poolliquiditypool=total liquidity in the poolstkIDLEuser=user stkIDLE balancestkIDLEtotsupply=total stkIDLE supplyliquidity_{user} = \text{user liquidity in the pool} \qquad liquidity_{pool} = \text{total liquidity in the pool} \\ stkIDLE_{user} = \text{user stkIDLE balance} \qquad stkIDLE_{tot\,supply} = \text{total stkIDLE supply}
The boost mechanism calculates user earning weight by taking the smaller amount of two values: the first value is the amount of liquidity the user is providing, while the second one is the amount of his maximum earning weight
min(liquidityuser+1.5×liquiditypool×stkIDLEuserstkIDLEtotsupply;2.5×liquidityuser)(1)\min\left(liquidity_{user} + 1.5 \times liquidity_{pool} \times \frac{stkIDLE_{user}}{stkIDLE_{tot\,supply}} ; 2.5 \times liquidity_{user}\right) \tag{1}
To achieve the maximum boost on rewards, the user needs to get 100% of the provided liquidity taken into account by the protocol. That is an equivalent share of stkIDLE supply bigger or equal to the share of liquidity in the pool
stkIDLEuserstkIDLEtotsupplyliquidityuserliquiditypool\frac{stkIDLE_{user}}{stkIDLE_{tot\,supply}} \ge \frac{liquidity_{user}}{liquidity_{pool}}
The gauge model considers a user with a share of stkIDLE higher than his share of liquidity provision in the pool as having 2.5x more liquidity than another user with no stkIDLE holding (in the same pool).

Boosting examples

Example 1: One user with the complete majority of stkIDLE share in the pool

Users
xx
and
yy
provide the same liquidity (100 stETH) in the senior tranche of the Lido pool and stake their senior tranche tokens (i.e. AA_wstETH) receiving an equal amount of rewards each (50% of $IDLE daily emission).
User
LP
% rewards
xx

100200=0.550%\frac{100}{200} = 0.5 \to 50\%
yy

100200=0.550%\frac{100}{200} = 0.5 \to 50\%
LIDO pool
200 stETH
100%100\%
Now, let’s suppose that user
xx
owns the total supply of stkIDLE in the pool (100%). The gauges boost calculator, using Equation (1), will consider user
xx
as bringing 250 stETH of liquidity in the pool, consequently boosting
xsx's
rewards by a multiplier of 1.42
User (stkIDLE)

yy

100×1=100100 \times 1 = 100
100250+100×100=29%\frac{100}{250 + 100} \times 100 = 29\%
multiplier(x)=1+(71%50%50%)=1.42multiplier(x) = 1 + \left(\frac{71\% - 50\%}{50\%}\right) = 1.42

Example 2: Two users with a significant difference in stkIDLE holding

User
xx
provides 100 stETH and user
yy
provides 9900 stETH in the senior tranche of the Lido pool. Assuming no stkIDLE holdings, user
xx
will earn 1% of the total pool rewards (AA_wstETH) and user
yy
99%.

User

stkIDLEuserliquidityuserstkIDLE_{user} \ge liquidity_{user}
. The gauges boost calculator, using Equation (1) will consider user
xx
as bringing 250 stETH of the liquidity in the pool, consequently boosting
xsx's
rewards by a multiplier of 2.5.
User (stkIDLE)

multiplier(x)=1+(2.5%1%1%)=2.5multiplier(x) = 1 + \left(\frac{2.5\% - 1\%}{1\%}\right) = 2.5
Similarly, if user
yy
stakes her $IDLE, she would own 1% of the stkIDLE supply of the pool, as well. The gauges boost calculator, using Equation (1) will consider user
yy
as bringing 1005 stETH of the liquidity in the pool, consequently boosting
ysy's
rewards by a multiplier of 2.5.
User (stkIDLE)

10050250+10050×10098%\frac{10050}{250+ 10050} \times 100 \approx 98\%
Share of earnings for user

would go from 97.54% to:
10050250+10050=97.57%\frac{10050}{250+ 10050} = 97.57\%
Users who own bigger shares of the pool need to hold bigger shares of the stkIDLE to boost significantly their rewards.
