Governance parameters
Protocol Governance parameters
Protocol Governance manages the global parameters of the protocol.
maxTokensPerVault
Maximum different tokens that a vault can manage
#
10
governanceDelay
The delay that has to pass for updating a certain class of params (delayed)
secs
86400
protocolTreasury
The treasury address for protocol fees
address
forceAllowMask
If a bit in this mask is set, the permission is allowed for all addresses
bitmask (uint256)
0
withdrawLimit
The maximum withdrawal per block. The hardcoded minimum value is 200_000 USD
USD
200_000
unitPrices
Token price estimates, used for withdrawLimit. For new token can be set immediately, for updates a cool-down period of 14 days is used.
address (token) => units of token per 1 USD
USDC => 10 ^ 6 ETH => 10 ^ 18 / 3000 BTC => 10 ^ 8 / 45000
Vault Governances parameters
Any Vault kind is governed by a Vault Governance contract. This contract is responsible for governing the parameters for this Vault kind. There are several types of parameters of any governance.
InternalParams are parameters common for all Vault Governances, to be staged in a constructor of a corresponding Vault Governance and to be updated with a delay by the Governance of the protocol, which are:
protocolGovernance
Governance of the protocol (ProtocolGovernance)
registry
Vault registry of the protocol (VaultRegistry)
singleton
Singleton instance of a certain Vault kind, serving as a prototype for all vaults of the Vault Group
delayedStrategyParams are parameters different for each Vault Governance and for each vault instance (typically being some parameters of the strategy set for an ERC20RootVault instance of this strategy), which may be updated with a delay by a Strategist or Governance
protocolPerVaultParams are parameters different for each Vault Governance and for each vault instance (typically being some protocol parameters of a single vault), which may be updated with a delay by the Governance
protocolParams are parameters common for all vaults of the Vault kind, which may be updated immediately by the Governance
delayedProtocolParams are parameters common for all vaults of the Vault kind, which may be updated with a delay by the Governance
operatorParams are parameters common for all vaults of the Vault kind, which may be updated immediately by a Strategist or Governance
Getting and setting parameters
There are, therefore, three types of parameters that are to be stated for all vaults of the Vault kind, and three types of parameters that are unique for each vault. These unique parameters are to be set and get not for a vault's address, but for a vault's NFT in the VaultRegistry. An example of getting (the same works for setting) parameters having just the address of a vault:
Take a deployed VaultRegistry contract and call
nftForVault(address)
, whereaddress
is the address of your vault. If the address is correct, you get an NFTnft
Take a corresponding Vault Governance contract and get the wanted parameters. For example, if your vault is ERC20RootVault, you can take the ERC20RootVaultGovernance deployed contract and call
delayedStrategyParams(nft)
, getting stated strategyParams for this vault
Note that a Vault Governance may not have any parameters of some type.
Here are the parameters of Vault Governances we currently have.
Aave VaultGovernance
delayedProtocolParams:
lendingPool
Aave lending pool
estimatedAaveAPY
Aave APY estimation for calculating tvl range
UniV3 VaultGovernance
delayedProtocolParams:
positionManager
UniV3 position manager
oracle
Oracle used for UniV3 price estimating
Yearn VaultGovernance
delayedProtocolParams:
yearnVaultRegistry
Yearn vault registry
As can be seen, Vault kinds on top of the other protocols have only delayedProtocolParams in which we set some basic addresses connected with those protocols which are needed to be called for all instances of this Vault kind.
ERC20 VaultGovernance and Euclidean Protocol VaultGovernance have no parameters.
ERC20Root VaultGovernance
You might want to see what ERC20Root Vault serves for.
strategyParams:

LP tokens limit per address
tokenLimit
LP tokens limit for a whole Vault System
delayedStrategyParams:
strategyTreasury
Address of the treasury used for collecting management fees
strategyPerformanceTreasury
Address of the treasury used for collecting performance fees
privateVault
If true, only allowed depositors may deposit to this vault
managementFee
Management fees rate (multiplied by DENOMINATOR = )
performanceFee
Performance fees rate (multiplied by DENOMINATOR = )
depositCallbackAddress

withdrawCallbackAddress
Address of callback function after deposit (to make some actions by subvaults in responde to a withdraw)
protocolPerVaultParams:
protocolFee
Protocol fees rate (multiplied by DENOMINATOR = )
delayedProtocolParams:

operatorParams:
