MsgPrivilegedExecuteContract

MsgPrivilegedExecuteContract defines a method for executing a Cosmwasm contract from the exchange module with privileged capabilities.

type MsgPrivilegedExecuteContract struct {
    Sender string
    // funds defines the user's bank coins used to fund the execution (e.g. 100inj).
    Funds github_com_cosmos_cosmos_sdk_types.Coins
    // contract_address defines the contract address to execute
    ContractAddress string
    // data defines the call data used when executing the contract
    Data string
}

Fields description

• Sender describes the creator of this msg.
• Funds defines the user's bank coins used to fund the execution (e.g. 100inj).
• ContractAddress defines the contract address to execute.
• Data defines the call data used when executing the contract.

Supported Privileged Actions

There are currently two supported privileged actions:

type PrivilegedAction struct {
    SyntheticTrade   *SyntheticTradeAction `json:"synthetic_trade"`
    PositionTransfer *PositionTransfer     `json:"position_transfer"`
}

These privileged actions must be set inside the Cosmwasm response data field, e.g.:

let privileged_action = PrivilegedAction {
    synthetic_trade: None,
    position_transfer: position_transfer_action,
};
response = response.set_data(to_binary(&privileged_action)?);

PositionTransfer

The position transfer allows a contract to transfer a position from its own subaccount to a user's subaccount.

type PositionTransfer struct {
    MarketID                common.Hash `json:"market_id"`
    SourceSubaccountID      common.Hash `json:"source_subaccount_id"`
    DestinationSubaccountID common.Hash `json:"destination_subaccount_id"`
    Quantity                sdk.Dec     `json:"quantity"`
}

SyntheticTrade

The synthetic trade allows a contract to execute a synthetic trade on behalf of a user.

type SyntheticTradeAction struct {
    UserTrades     []*SyntheticTrade `json:"user_trades"`
    ContractTrades []*SyntheticTrade `json:"contract_trades"`
}

type SyntheticTrade struct {
    MarketID     common.Hash `json:"market_id"`
    SubaccountID common.Hash `json:"subaccount_id"`
    IsBuy        bool        `json:"is_buy"`
    Quantity     sdk.Dec     `json:"quantity"`
    Price        sdk.Dec     `json:"price"`
    Margin       sdk.Dec     `json:"margin"`
}
