Building Blocks

Lending Market Owner/Authority:

This is the account that owns the entire pool -there is one for Main, Isolated, and etc.

Lending Market (State)

This contains all the reserves.

Reserves State (Market-level Positions)

For every pool, each token has its own reserve. This is where supply/balances are tracked, and is updated using the account value * pyth_price pulled from oracles.

Obligations State (User-level positions)

Each user’s position is called an obligation, and is updated using RefreshObligation by calling Pyth_price + the % of Liquidity provided (for supply) or cumulative borrow rate (for borrows)

Reserves State:

  • Asset: Reserve Token

  • Address: Reserve Address that contains the ATA of the liquidity

  • CollateralMintAddress: cToken Mint Address

  • CollateralSupplyAddress: Where cTokens are held to be used as collateral

  • Liquidity Address: ATA of the Reserve that contains the tokens

  • LiquidityFeeReceiverAddress: Where borrow fees generated are held before being swept into the protocol treasury
