Calculating TVL

Components of TVL - Measures the size of a DeFi protocol

1. DEX TVL

• Value of each asset in each pool
• sum of tvlUSD from the xx function in the subscanr package for R. You can also use the Karura-dex project hosted on Subquery Network with this query:

{ 
  dailyPools { 
    nodes { 
      timestamp token0 {id} token1 {id} feeRateUSD dailyTradeVolumeUSD totalTVL txCount updateAtBlock {id}  
    } 
  } 
}

2. LP Token Staking TVL

• Rewards from proving liquidity to a pool
• ACA (or KAR) obtained from the py-substrate-interface using function

substrate.query(module='Rewards',storage_function='PoolInfos', block_hash = hash)

3. Bridge TVL

• Value of non-native tokens bridged in (i.e DOT tokens bridged into Acala)
• KSM (or DOT) obtained from the py-substrate-interface using function

substrate.query(module='Tokens',storage_function='TotalIssuance', params = [{'Token': 'KSM'}], block_hash = hash)

• LKSM (or LDOT) obtained from function

substrate.query(module='Tokens',storage_function='TotalIssuance', params = [{'Token': 'LKSM'}], block_hash = hash)

4. Liquid Staking TVL

• Liquid staking is a form of staking where the derivative token can also be used in DeFi, providing additional yield beyond the regular staking yield.
• In the case of Acala, DOT obtained from the py-substrate-interface using function

substrate.query(module='Homa',storage_function='TotalStakingBonded', block_hash = hash)

5. Stablecoin TVL

• Value of stablecoin issued by a protocol (i.e. aUSD for Acala)
• sum of depositVolumeUSD from the getLoansDailyCollateral_acala_loan function in the subscanr package for R. You can also use the Karura-loan project hosted on Subquery Network with this query:

{ 
  dailyCollaterals { 
    nodes { 
      collateral {id} depositAmount debitAmount depositVolumeUSD debitVolumeUSD
      depositChangedUSD debitChangedUSD debitExchangeRate timestamp txCount 
    } 
  } 
}

6. Crowdloan TVL

• Value of DOT (or KSM) locked via the crowdloan process
• In the case of Acala, LCDOT obtained from the py-substrate-interface using function

substrate.query(module='Tokens',storage_function='TotalIssuance', params = [{'LiquidCrowdloan': 13}], block_hash = hash)

Alternative Measures of Size (What do we do for non-DeFi protocols?)

1. Market cap

• Total issuance of native token multiplied by price

2. Fees in USD

• Transaction fees converted into USD
