# State
|
|
|
|
## Parameters and genesis state
|
|
|
|
`Paramaters` define the rules according to which swaps are executed. Parameter updates can be made via on-chain parameter update proposals.
|
|
|
|
```go
|
|
// Params governance parameters for bep3 module
|
|
type Params struct {
|
|
BnbDeputyAddress sdk.AccAddress `json:"bnb_deputy_address" yaml:"bnb_deputy_address"` // deputy's address on Kava
|
|
BnbDeputyFixedFee uint64 `json:"bnb_deputy_fixed_fee" yaml:"bnb_deputy_fixed_fee"` // deputy's fixed fee
|
|
MinBlockLock uint64 `json:"min_block_lock" yaml:"min_block_lock"` // minimum swap expire height
|
|
MaxBlockLock uint64 `json:"max_block_lock" yaml:"max_block_lock"` // maximum swap expire height
|
|
SupportedAssets AssetParams `json:"supported_assets" yaml:"supported_assets"` // array of supported asset
|
|
}
|
|
|
|
// AssetParam governance parameters for each asset within a supported chain
|
|
type AssetParam struct {
|
|
Denom string `json:"denom" yaml:"denom"` // name of the asset
|
|
CoinID int `json:"coin_id" yaml:"coin_id"` // internationally recognized coin ID
|
|
Limit sdk.Int `json:"limit" yaml:"limit"` // asset supply limit
|
|
Active bool `json:"active" yaml:"active"` // denotes if asset is active or paused
|
|
}
|
|
```
|
|
|
|
`GenesisState` defines the state that must be persisted when the blockchain stops/restarts in order for normal function of the bep3 module to resume.
|
|
|
|
```go
|
|
// GenesisState - all bep3 state that must be provided at genesis
|
|
type GenesisState struct {
|
|
Params Params `json:"params" yaml:"params"`
|
|
AtomicSwaps AtomicSwaps `json:"atomic_swaps" yaml:"atomic_swaps"`
|
|
AssetSupplies AssetSupplies `json:"assets_supplies" yaml:"assets_supplies"`
|
|
}
|
|
```
|
|
|
|
