How is the TVL Calculated?
How is the TVL on the homepage of Position Exchange calculated?
Here is the code:
stakedAmountInNaivePoolPOSI, err := s.evmAdapter.GetPOSIBalance(constants.POSIStakingManagerAddress)
if err != nil {
return err
}
stakedAmountInNaivePoolPOSIV2, err := s.evmAdapter.GetPOSIBalance(constants.POSIStakingManagerV2Address)
if err != nil {
return err
}
stakedAmountInNFTPoolsPOSI, err := s.getStakedAmountInNFTPoolsPOSI()
if err != nil {
return err
}
stakedAmountInLPPairFarmsPOSI, err := s.getStakedAmountInLPPairFarmsPOSI()
if err != nil {
return err
}
USDPriceOfPOSI, err := s.redisAdapter.GetUSDPrice(ctx, constants.PositionExchangeContractAddress)
if err != nil {
return err
}
// stakedAmountInLPPairFarmsPOSI multiply 2 because LP value in USD is the same for the other token
// based on x.y = k formula
totalUSDValueLocked := stakedAmountInLPPairFarmsPOSI.Mul(decimal.NewFromInt(2)).Add(*stakedAmountInNaivePoolPOSI).Add(*stakedAmountInNaivePoolPOSIV2).Add(*stakedAmountInNFTPoolsPOSI).Mul(*USDPriceOfPOSI)
return s.redisAdapter.SetStatistics(ctx,
constants.PositionExchangeContractAddress,
constants.StatisticsTotalValueLockedFieldName,
&totalUSDValueLocked)
Explain:
(posi.balanceOf(POSIStakingManagerAddress) + posi.balanceOf(POSIStakingManagerV2Address)+posi.balanceOf(POSINFTMintProxyV1) + posi.balanceOf(POSINFTMintProxyV2) +(posi.balanceOf(BUSDLP) + posi.balanceOf(BNBLP))*2)*posiUSD
Where:
Variable | Value |
|---|---|
POSIStakingManagerAddress | 0x0c54b0b7d61de871db47c3ad3f69feb0f2c8db0b |
POSIStakingManagerV2Address | 0xB02de8F384613d0aa2521B188b55c4D006dDB2D1 |
POSINFTMintProxyV1 | 0x0Fb07a8527f45d7625Ab6486718910ce44a608b5 |
POSINFTMintProxyV2 | 0xd8b6E267a0A46E13047056F105787dB9aFFb4b9a |
BUSDLP | 0x00222D964a2077301309809Ab3bf56485C126A9C |
BNBLP | 0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c |
