Functions

func ChainedCustomQuerier 

func ChainedCustomQuerier(k ViewKeeper, next wasmkeeper.WasmVMQueryHandler) wasmkeeper.WasmVMQueryHandler

ChainedCustomQuerier implements the babylon custom query handler. The given WasmVMQueryHandler is receiving all unhandled queries and must therefore not be nil.

This CustomQuerier is designed as an extension point. See the NewQueryDecorator impl how to set this up for wasmd.

func NewIntegrityHandler 

func NewIntegrityHandler(k integrityHandlerSource) wasmkeeper.MessageHandlerFunc

NewIntegrityHandler prevents any contract with max cap set to use staking or stargate messages. This ensures that staked "virtual" tokens are not bypassing the instant undelegate and burn mechanism provided by babylon.

This handler should be chained before any other. TODO: access control for msg call from contracts

func NewMsgServer 

func NewMsgServer(k *Keeper) *msgServer

NewMsgServer constructor

func NewQuerier 

func NewQuerier(cdc codec.Codec, k *Keeper) *querier

NewQuerier constructor

func NewQueryDecorator 

func NewQueryDecorator(k ViewKeeper) func(wasmkeeper.WasmVMQueryHandler) wasmkeeper.WasmVMQueryHandler

NewQueryDecorator constructor to build a chained custom querier. The babylon custom query handler is placed at the first position and delegates to the next in chain for any queries that do not match the babylon custom query namespace.

To be used with `wasmkeeper.WithQueryHandlerDecorator(BabylonKeeper.NewQueryDecorator(app.BabylonKeeper)))`

Types

type AuthSource 

type AuthSource interface {
	// IsAuthorized returns if the contract authorized to execute a virtual stake message
	IsAuthorized(ctx sdk.Context, contractAddr sdk.AccAddress) bool
}

AuthSource abstract type that provides contract authorization. This is an extension point for custom implementations.

type AuthSourceFn 

type AuthSourceFn func(ctx sdk.Context, contractAddr sdk.AccAddress) bool

AuthSourceFn is helper for simple AuthSource types

func (AuthSourceFn) IsAuthorized 

func (a AuthSourceFn) IsAuthorized(ctx sdk.Context, contractAddr sdk.AccAddress) bool

IsAuthorized returns if the contract authorized to execute a virtual stake message

type CustomMsgHandler 

type CustomMsgHandler struct {
	// contains filtered or unexported fields
}

func NewCustomMsgHandler 

func NewCustomMsgHandler(k babylonKeeper, auth AuthSource) *CustomMsgHandler

NewCustomMsgHandler constructor to set up CustomMsgHandler with an individual auth source. This is an extension point for non default contract authorization logic.

func NewDefaultCustomMsgHandler 

func NewDefaultCustomMsgHandler(k *Keeper) *CustomMsgHandler

NewDefaultCustomMsgHandler constructor to set up the CustomMsgHandler with default max cap authorization

func (CustomMsgHandler) DispatchMsg 

func (h CustomMsgHandler) DispatchMsg(ctx sdk.Context, contractAddr sdk.AccAddress, _ string, msg wasmvmtypes.CosmosMsg) ([]sdk.Event, [][]byte, [][]*codectypes.Any, error)

DispatchMsg handle contract message of type Custom in the babylon namespace

type Keeper 

type Keeper struct {
	Staking types.StakingKeeper
	// contains filtered or unexported fields
}

func NewKeeper 

func NewKeeper(
	cdc codec.Codec,
	storeKey storetypes.StoreKey,
	memoryStoreKey storetypes.StoreKey,
	bank types.BankKeeper,
	staking types.StakingKeeper,
	wasm *wasmkeeper.Keeper,
	authority string,
	opts ...Option,
) *Keeper

NewKeeper constructor with vanilla sdk keepers

func (*Keeper) BeginBlocker 

func (k *Keeper) BeginBlocker(ctx context.Context) error

func (Keeper) CanInvokeStakingMsg 

func (k Keeper) CanInvokeStakingMsg(ctx sdk.Context, actor sdk.AccAddress) bool

func (*Keeper) EndBlocker 

func (k *Keeper) EndBlocker(ctx context.Context) ([]abci.ValidatorUpdate, error)

EndBlocker is called after every block

func (Keeper) ExportGenesis 

func (k Keeper) ExportGenesis(ctx sdk.Context) *types.GenesisState

func (Keeper) GetAuthority 

func (k Keeper) GetAuthority() string

GetAuthority returns the module's authority.

func (Keeper) GetMaxSudoGas 

func (k Keeper) GetMaxSudoGas(ctx sdk.Context) storetypes.Gas

func (Keeper) GetParams 

func (k Keeper) GetParams(clientCtx sdk.Context) (params types.Params)

GetParams gets the module's parameters.

func (Keeper) GetTest 

func (k Keeper) GetTest(ctx sdk.Context, actor sdk.AccAddress) string

func (Keeper) InitGenesis 

func (k Keeper) InitGenesis(ctx sdk.Context, data types.GenesisState)

func (Keeper) InstantiateBabylonContracts 

func (k Keeper) InstantiateBabylonContracts(
	ctx sdk.Context,
	babylonContractCodeId uint64,
	initMsg []byte,
) (string, string, string, error)

func (Keeper) Logger 

func (k Keeper) Logger(ctx sdk.Context) log.Logger

func (Keeper) MintBlockRewards 

func (k Keeper) MintBlockRewards(pCtx sdk.Context, recipient sdk.AccAddress, amt sdk.Coin) (sdkmath.Int, error)

MintBlockRewards mints new tokens and sends them to the finality contract for distribution. Authorization of the actor should be handled before entering this method. Authorization of the recipient is being handled within the method for safety, but can be removed for flexibility

func (Keeper) SendBeginBlockMsg 

func (k Keeper) SendBeginBlockMsg(c context.Context) error

SendBeginBlockMsg sends a BeginBlock sudo message to the BTC finality contract via sudo

func (Keeper) SendEndBlockMsg 

func (k Keeper) SendEndBlockMsg(c context.Context) error

SendEndBlockMsg sends a EndBlock sudo message to the BTC finality contract via sudo

func (Keeper) SetParams 

func (k Keeper) SetParams(ctx sdk.Context, params types.Params) error

SetParams sets the module's parameters.

type Option 

type Option interface {
	// contains filtered or unexported methods
}

Option is an extension point to instantiate keeper with non default values

func WithWasmKeeperDecorated 

func WithWasmKeeperDecorated(cb func(*wasmkeeper.Keeper) *wasmkeeper.Keeper) Option

WithWasmKeeperDecorated can set a decorator to the wasm keeper

type QueryHandlerFn 

type QueryHandlerFn func(ctx sdk.Context, caller sdk.AccAddress, request wasmvmtypes.QueryRequest) ([]byte, error)

QueryHandlerFn helper type that implements wasmkeeper.WasmVMQueryHandler

HandleQuery handles contract query

type ViewKeeper 

type ViewKeeper interface {
	GetTest(ctx sdk.Context, actor sdk.AccAddress) string
}

abstract query keeper
