Schema Updates

Schema Update 1.2.1

Main commit: 0300919

Common

  • The ID of hourly snapshots has been changed from { # of days since Unix epoch time }-{ HH: hour of the day } to { # of hours since Unix epoch time }.

Schema Update 1.2.0

Main PR: #88
Fixes: #109, #111

Common

  • Added prefixes to diambiguate quantitative fields:
    • cumulative: sum of all historical data from day 1 up to this point. E.g. cumulativeDepositUSD means all deposits has ever been made to this protocol/pool.
    • daily/hourly: this only applies to snapshots and represents the sum of the snapshot interval (i.e. daily aggregate). E.g. dailyActiveUsers means all unique active users on a given day, up till now.
    • All other quantitative field indicates a spot balance. In other words, the value at this point in time. E.g. totalValueLockedUSD means the total TVL of the protocol/pool as of now.
  • Updated chain enums to match dataSource.network().
  • Added lastPriceUSD and lastPriceBlockNumber as optional fields in the Token entity for tracking prices.
  • Refactored RewardToken to include Token as a field.
  • For snapshots, now saving both cumulative values and daily aggregates.
  • Now saving hourly snapshots for usage metrics and pool data.

DEX-AMM

  • Added more detailed usage metrics: deposit/withdraw/swap count.
  • Added inputTokenWeights: [BigDecimal!]! to track pool composition.
  • Added per-token volume dailyVolumeByTokenUSD: [BigDecimal!]! to LiquidityPoolDailySnapshot.
  • Named PoolDailySnapshot to LiquidityPoolDailySnapshot for consistency.
  • Added stakedOutputTokenAmount: BigInt to LiquidityPool and LiquidityPoolDailySnapshot.

Lending Protocol

  • Added more detailed usage metrics: deposit/withdraw/repay/liquidate count.
  • Now aggregating deposit/borrow/liquidation USD values.
  • Added InterestRate entity and made rates into an array.
  • Added mintedTokens and mintedTokenSupplies to the LendingProtocol entity.
  • Added exchangeRate: BigDecimal to Market and MarketDailySnapshot entity.
  • Assume only a single input token (i.e. changed inputTokens to inputToken).
  • Updated comments to the Liquidate event for clarity.

Yield Aggregator

  • Added more detailed usage metrics: deposit/withdraw count.
  • Assume only a single input token (i.e. changed inputTokens to inputToken).

Generic

  • Added stakedOutputTokenAmount: BigInt. See #87

Schema Update 1.1.0

Main PR: #47
Fixes: #69, #70, #78, #80, #85

Common Changes

  • Changed feesUSD to totalRevenueUSD. For DEXes and Lending Protocols, everything stays the same since fees = totalRevenue. For yield aggregator, you now need to include all revenue (including supply side portion).
  • Added methodologyVersion to the Protocol interface/entity so that we can track which methodology is being used.
  • Removed protocolTreasuryUSD field from the FinanceDailySnapshot entity
  • Removed the Pool and PoolDailySnapshot interface for clarity
  • Added Account and DailyActiveAccount as a part of all schemas, since they are always used to compute usage metrics
  • Added totalVolumeUSD to the Protocol interface to make aggregator easier
  • Added a lot of documentation

Protocol-Type Specific Changes

  • Added totalDepositUSD and totalBorrowUSD to the Lending schema. Note that totalDepositUSD should be the same as totalValueLockedUSD but totalBorrowUSD is different from totalVolumeUSD since the former is a point in time and latter is in aggregate.
  • Made outputToken-related fields optional in the DEX schema since Bancor v2 doesn't have LP token (output token)
  • Updated LiquidityPoolFeeType to account for LP fees
  • Updated to/from fields for DEX deposit/withdraw
  • Added pricePerShare to yield aggregator schema (Yield Aggregator 1.1.1)
  • Added inputTokenWeights to DEX AMM schema (DEX AMM 1.1.1)
  • Change stableInterestRate in the lending schema to optional. See #85
