# Inflation Design

The CLV chain adopts the same inflation design as Polkadot's, as it's a proven and long-term economical design that we think fulfills the future development of the CLV ecosystem.&#x20;

Inflation to validators is dynamic, between 2.25% - 20% annually, depending on $CLV staking rate on CLV Mainnet.&#x20;

Although the total number of $CLV in circulation is the combination of the number of tokens on 4 chains ($CLV on Ethereum, BNB Chain, CLV Parachain and CLV Mainnet), the inflation model is only subject to the amount of $CLV circulating on the CLV Mainnet.

### Inflation & Staking Rate Formula <a href="#dd3b" id="dd3b"></a>

![Formula for inflation and interest rate](/files/x2PZwueQp3Jx0khsvyma)

The value of the staking rate should lie between 30% and 60% - **ideally at 50%.** If it falls, the security is compromised, so we should give strong incentives to $CLV holders to stake more of their assets. If it rises, we lose liquidity, so we should decrease the incentives sharply.

`x = staking rate(x is always a value between 0 and 1)`\
\&#xNAN;*`green graph`*` ``= i (x) yearly`` `*`interest rate`*\
\&#xNAN;*`blue graph =`*` ``I (x)`` `*`inflation rate to stakers`*

x-axis represents the total staking rate, y-axis interest rate (green) or inflation to validator rate (blue)

1. &#x20;Number 1 displayed in the graph is the minimum of the inflation to stakers (i.e. when neither validators nor nominators are staking $CLV). It’s the inflation “starting” point; 0.025 → 2.5% in this case goes away for validator rewards.
2. The second number shows a linear increase of inflation if the staking rate is between 0 and 50%. There is a linear correlation between the staking rate and inflation till 0.5 is reached. The inflation rate is 5% if the staking rate is at 25%. If the staking rate doubles to 50%, so does the inflation rate to 10%. But remember: It is only linear till 50% staking rate is reached.&#x20;
3. The red line at number 3 is the ideal staking rate of 50%. In this case, the annual staking reward is at 20%. But if the staking rates exceeds 50%, there is an exponential decay in inflation, which results in a strong decay of staking rewards. The reason for that is that the network needs liquidity and decreases the incentives sharply if the staking rate exceeds 50%.&#x20;
