README

CosmWasm support

This package contains CosmWasm integration points.

This package provides first class support for:

  • Queries
    • Denoms
    • Pools
    • Prices
  • Messages / Execution
    • Minting / controlling of new native tokens
    • Swap

Command line interface (CLI)

  • Commands
  osmosisd tx wasm -h
  • Query
  osmosisd query wasm -h

Tests

This contains a few high level tests that x/wasm is properly integrated.

Since the code tested is not in this repo, and we are just testing the application integration (app.go), I figured this is the most suitable location for it.

Functions

func ChangeAdmin 

func ChangeAdmin(f *tokenfactorykeeper.Keeper, ctx sdk.Context, contractAddr sdk.AccAddress, changeAdmin *bindings.ChangeAdmin) error

ChangeAdmin is used with changeAdmin to validate changeAdmin messages and to dispatch.

func ConvertProtoToJSONMarshal 

func ConvertProtoToJSONMarshal(protoResponseType codec.ProtoMarshaler, bz []byte, cdc codec.Codec) ([]byte, error)

ConvertProtoToJsonMarshal unmarshals the given bytes into a proto message and then marshals it to json. This is done so that clients calling stargate queries do not need to define their own proto unmarshalers, being able to use response directly by json marshalling, which is supported in cosmwasm.

func ConvertSdkCoinToWasmCoin 

func ConvertSdkCoinToWasmCoin(coin sdk.Coin) wasmvmtypes.Coin

ConvertSdkCoinToWasmCoin converts a sdk type coin to a wasm vm type coin

func ConvertSdkCoinsToWasmCoins 

func ConvertSdkCoinsToWasmCoins(coins []sdk.Coin) wasmvmtypes.Coins

ConvertSdkCoinsToWasmCoins converts sdk type coins to wasm vm type coins

func CustomMessageDecorator 

func CustomMessageDecorator(gammKeeper *gammkeeper.Keeper, bank *bankkeeper.BaseKeeper, tokenFactory *tokenfactorykeeper.Keeper) func(wasmkeeper.Messenger) wasmkeeper.Messenger

CustomMessageDecorator returns decorator for custom CosmWasm bindings messages

func CustomQuerier 

func CustomQuerier(qp *QueryPlugin) func(ctx sdk.Context, request json.RawMessage) ([]byte, error)

CustomQuerier dispatches custom CosmWasm bindings queries.

func GetFullDenom 

func GetFullDenom(contract string, subDenom string) (string, error)

GetFullDenom is a function, not method, so the message_plugin can use it

func GetWhitelistedQuery 

func GetWhitelistedQuery(queryPath string) (codec.ProtoMarshaler, error)

GetWhitelistedQuery returns the whitelisted query at the provided path. If the query does not exist, or it was setup wrong by the chain, this returns an error.

func PerformBurn 

func PerformBurn(f *tokenfactorykeeper.Keeper, ctx sdk.Context, contractAddr sdk.AccAddress, burn *bindings.BurnTokens) error

PerformBurn performs token burning after validating tokenBurn message.

func PerformCreateDenom 

func PerformCreateDenom(f *tokenfactorykeeper.Keeper, b *bankkeeper.BaseKeeper, ctx sdk.Context, contractAddr sdk.AccAddress, createDenom *bindings.CreateDenom) error

PerformCreateDenom is used with createDenom to create a token denom; validates the msgCreateDenom.

func PerformMint 

func PerformMint(f *tokenfactorykeeper.Keeper, b *bankkeeper.BaseKeeper, ctx sdk.Context, contractAddr sdk.AccAddress, mint *bindings.MintTokens) error

PerformMint used with mintTokens to validate the mint message and mint through token factory.

func PerformSwap 

func PerformSwap(keeper *gammkeeper.Keeper, ctx sdk.Context, contractAddr sdk.AccAddress, swap *bindings.SwapMsg) (*bindings.SwapAmount, error)

PerformSwap can be used both for the real swap, and the EstimateSwap query

func RegisterCustomPlugins 

func RegisterCustomPlugins(
	gammKeeper *gammkeeper.Keeper,
	bank *bankkeeper.BaseKeeper,
	twap *twap.Keeper,
	tokenFactory *tokenfactorykeeper.Keeper,
) []wasmkeeper.Option

func RegisterStargateQueries 

func RegisterStargateQueries(queryRouter baseapp.GRPCQueryRouter, codec codec.Codec) []wasmkeeper.Option

func StargateQuerier 

func StargateQuerier(queryRouter baseapp.GRPCQueryRouter, cdc codec.Codec) func(ctx sdk.Context, request *wasmvmtypes.StargateQuery) ([]byte, error)

StargateQuerier dispatches whitelisted stargate queries

Types

type CustomMessenger 

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

func (*CustomMessenger) DispatchMsg 

func (m *CustomMessenger) DispatchMsg(ctx sdk.Context, contractAddr sdk.AccAddress, contractIBCPortID string, msg wasmvmtypes.CosmosMsg) ([]sdk.Event, [][]byte, error)

DispatchMsg executes on the contractMsg.

type QueryPlugin 

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

func NewQueryPlugin 

func NewQueryPlugin(gk *gammkeeper.Keeper, tk *twapkeeper.Keeper, tfk *tokenfactorykeeper.Keeper) *QueryPlugin

NewQueryPlugin returns a reference to a new QueryPlugin.

func (QueryPlugin) ArithmeticTwap 

func (qp QueryPlugin) ArithmeticTwap(ctx sdk.Context, arithmeticTwap *bindings.ArithmeticTwap) (*sdk.Dec, error)

func (QueryPlugin) ArithmeticTwapToNow 

func (qp QueryPlugin) ArithmeticTwapToNow(ctx sdk.Context, arithmeticTwap *bindings.ArithmeticTwapToNow) (*sdk.Dec, error)

func (QueryPlugin) EstimateSwap 

func (qp QueryPlugin) EstimateSwap(ctx sdk.Context, estimateSwap *bindings.EstimateSwap) (*bindings.SwapAmount, error)

EstimateSwap validates each denom (in / out) and performs a swap.

func (QueryPlugin) GetDenomAdmin 

func (qp QueryPlugin) GetDenomAdmin(ctx sdk.Context, denom string) (*bindings.DenomAdminResponse, error)

GetDenomAdmin is a query to get denom admin.

func (QueryPlugin) GetPoolState 

func (qp QueryPlugin) GetPoolState(ctx sdk.Context, poolID uint64) (*bindings.PoolAssets, error)

GetPoolState is a query to get pool liquidity and amount of each denoms' pool shares.

func (QueryPlugin) GetSpotPrice 

func (qp QueryPlugin) GetSpotPrice(ctx sdk.Context, spotPrice *bindings.SpotPrice) (*sdk.Dec, error)

GetSpotPrice is a query to get spot price of denoms.
