# Deployed Zoe Contracts
In the mainnet-1B release of agoric-sdk (opens new window), the chain is configured to automatically deploy the following Zoe contracts. A community post on Inter Protocol Vaults Contract Implementations (opens new window) has a high level description.
|used to initialize the vbank IST purse balance based on supply reported from the cosmos x/bank module
|use to hold mints for BLD as well as inter-chain assets such as ATOM, USDC, and USDT
|represents the Economic Committee that governs Inter Protocol parameters
|instantiated once for each question that a committee votes on
|controls what questions can be put to the economic committee
|each governed contract is started by starting its governor
|The Parity Stability Module (PSM) supports efficiently minting and burning Inter Stable Tokens (ISTs) in exchange for approved external stable tokens.
|allows users to mint IST backed by collateral such as ATOM; hands off vaults to auctioneer when value of collateral in a vault falls below a governed threshold
|auctions collateral from liquidated vaults
|aggregates prices from oracle oeprators
|provides prices for tradeable assets such as ATOM in terms of idealized "oracle ATOM" prices from oracle operators
|collects fees from Inter Protocol contracts and distributes to reserve and/or stakers
|holds assets in reserve to back IST
|executes Zoe offers on behalf of users
