Pool Data
Key Data Structures
Root element of the protocol is the PoolFactory, which contains a list of Pool contracts ordered by time of creation. Each pool is identified externally by its contract address and internally by index. 
Each pool contains a list of derivatives, indexed internally by the creation time. 
Each derivative consists of a pair of long ("primary") - short ("complement") pair, indexed as 0 and 1 respectively.
The three indices above are required to query derivative price and user balance.
Set-Up 
Basic Pool Factory and Pool ABIs are available here and the Pool Factory address here. Any available script library such as Truffle or Hardhat can be used to request on-chain data and execute transacions.
This guide will use seth - a tool built by Dapphub to interact directly with smart contracts. To install, run the command below (note:Dapp Tools suite installs Nix OS):
curl https://dapp.tools/install | sh
Follow the remaining steps to select the SETH_CHAIN and address/key: https://github.com/dapphub/dapptools/tree/master/src/seth#example-sethrc-file 
Set pool factory proxy address to iterate through the pools:
$POOL_FACTORY_PROXY=/set address by the network/
Pool Configs
Get pool addresses:
seth call $POOL_FACTORY_PROXY "getAllPools()" # returns all pools addresses
Get pool configs:
seth call $POOL "getConfig()" # returns PoolConfig structure
#  struct PoolConfig {
#    uint256 minExitAmount; // minimal LP share tokens exit amount
#    uint256 protocolFee; // protocol fee percentage ( multiplied 10^26)
#    address feeWallet; // protocol fee collector
#    address collateralToken; // pool's collateral token
#    address collateralOracle; // collateral price feed
#    address collateralOracleIterator; // collateral price feed iterator
#    address volatilityEvolution;
#    address underlyingLiquidityValuer;
#    address exposure; // pool's market exposure level calculator
#    address poolShare; // pool's LP token
#    address traderPortfolio; // trader portfolio NFT token
#    uint8 collateralDecimals; // colletersl ERC20 decimals param
#  }
Pool Metadata
Trader Portfolio and Pool Share metadata (token's name and symbol) can be requested as standard ERC721 and ERC20 parameters. 
Labels below are of the form [Protocol]-[Pool Collateral]-[Derivative Type]. Please note that this form is expected to change in the future, as pools admit more than one type of derivative.
