CosmWasm support

This package contains CosmWasm integration points.

This package provides first class support for:

• Queries
  • Denoms
  • Pools
  • Prices
• Messages / Execution
  • Mint
  • 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 *wasmbindings.ChangeAdmin) error

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

func CustomQuerier

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

func GetFullDenom

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

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

func PerformBurn

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

func PerformCreateDenom

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

func PerformMint

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

func PerformSwap

func PerformSwap(keeper *gammkeeper.Keeper, ctx sdk.Context, contractAddr sdk.AccAddress, swap *wasmbindings.SwapMsg) (*wasmbindings.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,
	tokenFactory *tokenfactorykeeper.Keeper,
) []wasmkeeper.Option
