The issuer can issue new tokens using a `MsgIssueTokens`
|
||
|
|
|
||
|
|
```go
|
||
|
|
// 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`.
|
||
|
|
|
||
|
|
```go
|
||
|
|
// 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`
|
||
|
|
|
||
|
|
```go
|
||
|
|
// 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`
|
||
|
|
|
||
|
|
```go
|
||
|
|
// 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 `Paused` value of the correspond asset is updated to `Status`.
|
||
|
|
* Issuance and redemption are paused if `Paused` is false
