Msg/CreateInsuranceFund​

MsgCreateInsuranceFund defines a message to create an insurance fund for a derivative market.

// MsgCreateInsuranceFund a message to create an insurance fund for a derivative market.
message MsgCreateInsuranceFund {
  option (gogoproto.equal) = false;
  option (gogoproto.goproto_getters) = false;
  // Creator of the insurance fund.
  string sender = 1;
  // Ticker for the derivative market.
  string ticker = 2;
  // Coin denom to use for the market quote denom
  string quote_denom = 3;
  // Oracle base currency
  string oracle_base = 4;
  // Oracle quote currency
  string oracle_quote = 5;
  // Oracle type
  injective.oracle.v1beta1.OracleType oracle_type = 6;
  // Expiration time of the market. Should be -1 for perpetual markets.
  int64 expiry = 7;
  // Initial deposit of the insurance fund
  cosmos.base.v1beta1.Coin initial_deposit = 8 [(gogoproto.nullable) = false];
}

Fields description

  • Sender field describes the creator of an insurance fund .
  • Ticker, QuoteDenom, OracleBase, OracleQuote, OracleType, Expiry fields describe the derivative market info that the insurance fund corresponds to.
  • InitialDeposit specifies the initial deposit amount used to underwrite the insurance fund.

Disclaimer: When creating an insurance fund a small portion of shares (1%) will be reserved by the fund itself (protocol owned liquidity). A value of 1 USD is recommended as first subscription.

Motivation behind this feature is to avoid potential rounding issues when underwriting to a fund. For example, without having protocol owned liquidity, if the original fund creator would take out most of their shares leaving but a small amount, the value of the share token could diverge drastically from the original value. The next underwriter would then have to provide a much larger deposit despite gaining the same amount of shares.
