The issuer can issue new tokens using a MsgIssueTokens
// MsgIssueTokens message type used to issue tokens
type MsgIssueTokens struct {
  Sender   sdk.AccAddress `json:"sender" yaml:"sender"`
  Tokens   sdk.Coin       `json:"tokens" yaml:"tokens"`
  Receiver sdk.AccAddress `json:"receiver" yaml:"receiver"`
}
State Modifications
- New tokens are minted from the issuance module account
 - New tokens are transferred from the module account to the receiver
 
The issuer can redeem (burn) tokens using MsgRedeemTokens.
// MsgRedeemTokens message type used to redeem (burn) tokens
type MsgRedeemTokens struct {
  Sender sdk.AccAddress `json:"sender" yaml:"sender"`
  Tokens sdk.Coin       `json:"tokens" yaml:"tokens"`
}
State Modifications
- Tokens are transferred from the owner address to the issuer module account
 - Tokens are burned
 
Addresses can be added to the blocked list using MsgBlockAddress
// MsgBlockAddress message type used by the issuer to block an address from holding or transferring tokens
type MsgBlockAddress struct {
	Sender         sdk.AccAddress `json:"sender" yaml:"sender"`
	Denom          string         `json:"denom" yaml:"denom"`
	BlockedAddress sdk.AccAddress `json:"blocked_address" yaml:"blocked_address"`
}
State Modifications
- The address is added to the block list, which prevents the account from holding coins of that denom
 - Tokens are sent back to the issuer
 
The issuer can pause or un-pause the contract using MsgChangePauseStatus
// MsgChangePauseStatus message type used by the issuer to issue new tokens
type MsgChangePauseStatus struct {
	Sender sdk.AccAddress `json:"sender" yaml:"sender"`
	Denom  string         `json:"denom" yaml:"denom"`
	Status bool           `json:"status" yaml:"status"`
}
State Modifications
- The 
Pausedvalue of the correspond asset is updated toStatus. - Issuance and redemption are paused if 
Pausedis false
