Administrative Operations
Administrative operations include creating banks and vaults, managing oracle price feeds, controlling team investment activities, and emergency circuit breaker functionality.
These operations are restricted to specific authorized accounts and require elevated privileges compared to user operations. For user-facing operations like minting and burning USD*, see User Operations.
Administrative Instruction Categories
Administrative operations in the bankineco program fall into several key categories:
System Creation and Configuration
Bank Creation: Initialize new banks that can issue USD* tokens
Vault Creation: Create new vaults for different asset types and yield strategies
Team Account Setup: Establish team accounts for vault management and fee collection
Oracle Configuration: Set up price feed mechanisms for yield-bearing assets
Price and Yield Management
Oracle Price Updates: Update asset prices from authorized oracle sources
Yield Information Updates: Report external yield generation for investment vaults
Team Investment Operations
External Investment Withdrawals: Move assets from vaults to external yield strategies
Investment Returns: Deposit returns from external investments back to vaults
Fee Collection: Withdraw accumulated fees to team accounts
Vault Configuration
Vault Creation Process
The create_gen_vault instruction initializes a new vault with specified parameters:
vault_type
Type of vault (YieldBearing, UnCollateralizedExternalYield, etc.)
Must be valid VaultType enum
yielding_token_index
Index for the yielding token within the bank
Must be unique within bank
default_fee_bps
Default fee in basis points for minting/burning
Applied to both minting and burning
The vault is initially created in a halted state and requires additional configuration before it can accept user operations. Key initialization includes:
Setting vault type and yielding token configuration
Creating associated token account for holding vault assets
Registering vault in the bank's vault registry
Initializing accounting fields to zero
Setting default fee structures
Investment Withdrawal Flow
The team_withdraws_to_invest instruction:
Validates the caller is the authorized external yield manager
Transfers yielding tokens from vault to external manager
Updates accounting to track external investment amounts
Maintains vault state consistency through sanitization checks
Investment Return Flow
The team_deposits_from_invest instruction reverses the investment process by returning tokens to the vault and reducing the tracked external investment amounts.
