Not good condition to handle MsgStoreCodeAndInstantiateContract

Wasm Zone

This repository hosts Wasmd, the first implementation of a cosmos zone with wasm smart contracts enabled.

This code was forked from the cosmwasm/wasmd repository as a basis and cosmwasm/wasmd was forked from the cosmos/gaia repository, and then we change x/wasm. However, the wasmd binary should function just like gaiad except for the addition of the x/wasm module.

Note: Requires Go 1.20+

Compatibility with CosmWasm contracts

Compatibility

A VM can support one or more contract-VM interface versions. The interface version is communicated by the contract via a Wasm export. This is the current compatibility list:

Finschia/wasmd	cosmwasm/wasmd	Finschia/wasmvm	cosmwasm/wasmvm	Finschia/cosmwasm-std	cosmwasm/cosmwasm-vm	cosmwasm/cosmwasm-std
0.3	0.29.1	v1.1.1-0.12.0	v1.1.1	1.1.9+0.9.0		1.1.9
0.2	0.29.1	v1.1.1-0.11.6	v1.1.1	1.1.9+0.8.1		1.1.9
	0.29		v1.1.0			1.0-1.1
	0.28		v1.0.0			1.0-1.1
0.1	0.27	v1.0.0-0.10.0	v1.0.0			1.0
	0.26		1.0.0-beta10			1.0
	0.25		1.0.0-beta10			1.0
	0.24		1.0.0-beta7		1.0.0-beta6	1.0
	0.23				1.0.0-beta5	1.0
	0.22				1.0.0-beta5	1.0
	0.21				1.0.0-beta2	1.0
	0.20				1.0.0-beta	1.0
	0.19				0.16	0.16
	0.18				0.16	0.16
	0.17				0.14	0.14
	0.16				0.14	0.14
	0.15				0.13	0.11-0.13
	0.14				0.13	0.11-0.13
	0.13				0.12	0.11-0.13
	0.12				0.12	0.11-0.13
	0.11				0.11	0.11-0.13
	0.10				0.10	0.10
	0.9				0.9	0.9
	0.8				0.8	0.8

Note: cosmwasm_std v1.0 means it supports contracts compiled by any v1.0.0-betaX or 1.0.x. It will also run contracts compiled with 1.x assuming they don't opt into any newer features. The 1.x cosmwasm_vm will support all contracts with 1.0 <= version <= 1.x.

Note that cosmwasm-std version defines which contracts are compatible with this system. The wasm code uploaded must have been compiled with one of the supported cosmwasm-std versions, or will be rejected upon upload (with some error message about "contract too old?" or "contract too new?"). cosmwasm-vm version defines the runtime used. It is a breaking change to switch runtimes (you will need to organize a chain upgrade). As of cosmwasm-vm 0.13 we are using wasmer 1.0, which is significantly more performant than the older versions.

Supported Systems

The supported systems are limited by the dlls created in wasmvm. In particular, we only support MacOS and Linux. However, M1 macs are not fully supported. (Experimental support was merged with wasmd 0.24) For linux, the default is to build for glibc, and we cross-compile with CentOS 7 to provide backwards compatibility for glibc 2.12+. This includes all known supported distributions using glibc (CentOS 7 uses 2.12, obsolete Debian Jessy uses 2.19).

As of 0.9.0 we support muslc Linux systems, in particular Alpine linux, which is popular in docker distributions. Note that we do not store the static muslc build in the repo, so you must compile this yourself, and pass -tags muslc. Please look at the Dockerfile for an example of how we build a static Go binary for muslc. (Or just use this Dockerfile for your production setup).

Stability

This is beta software It is run in some production systems, but we cannot yet provide a stability guarantee and have not yet gone through and audit of this codebase. Note that the CosmWasm smart contract framework used by wasmd is in a 1.0 release candidate as of March 2022, with stability guarantee and addressing audit results.

As of wasmd 0.22, we will work to provide upgrade paths for this module for projects running a non-forked version on their live networks. If there are Cosmos SDK upgrades, you will have to run their migration code for their modules. If we change the internal storage of x/wasm we will provide a function to migrate state that can be called by an x/upgrade handler.

The APIs are pretty stable, but we cannot guarantee their stability until we reach v1.0. However, we will provide a way for you to hard-fork your way to v1.0.

Thank you to all projects who have run this code in your mainnets and testnets and given feedback to improve stability.

Encoding

The used cosmos-sdk version is in transition migrating from amino encoding to protobuf for state. So are we now.

We use standard cosmos-sdk encoding (amino) for all sdk Messages. However, the message body sent to all contracts, as well as the internal state is encoded using JSON. Cosmwasm allows arbitrary bytes with the contract itself responsible for decoding. For better UX, we often use json.RawMessage to contain these bytes, which enforces that it is valid json, but also give a much more readable interface. If you want to use another encoding in the contracts, that is a relatively minor change to wasmd but would currently require a fork. Please open an issue if this is important for your use case.

Quick Start

make install
make test

if you are using a linux without X or headless linux, look at this article or #31.

Protobuf

The protobuf files for this project are published automatically to the buf repository to make integration easier:

wasmd version	buf tag
0.26.x	51931206dbe09529c1819a8a2863d291035a2549

Generate protobuf

make proto-gen

The generators are executed within a Docker container, now.

Runtime flags

We provide a number of variables in app/app.go that are intended to be set via -ldflags -X ... compile-time flags. This enables us to avoid copying a new binary directory over for each small change to the configuration.

Available flags:

-X github.com/Finschia/wasmd/app.NodeDir=.corald - set the config/data directory for the node (default ~/.wasmd)
-X github.com/Finschia/wasmd/app.Bech32Prefix=coral - set the bech32 prefix for all accounts (default wasm)
-X github.com/Finschia/wasmd/app.ProposalsEnabled=true - enable all x/wasm governance proposals (default false)
-X github.com/Finschia/wasmd/app.EnableSpecificProposals=MigrateContract,UpdateAdmin,ClearAdmin - enable a subset of the x/wasm governance proposal types (overrides ProposalsEnabled)

Examples:

wasmd is a generic, permissionless version using the cosmos bech32 prefix

Compile Time Parameters

Besides those above variables (meant for custom wasmd compilation), there are a few more variables which we allow blockchains to customize, but at compile time. If you build your own chain and import x/wasm, you can adjust a few items via module parameters, but a few others did not fit in that, as they need to be used by stateless ValidateBasic(). Thus, we made them public var and these can be overridden in the app.go file of your custom chain.

wasmtypes.MaxLabelSize = 64 to set the maximum label size on instantiation (default 128)
wasmtypes.MaxWasmSize=777000 to set the max size of compiled wasm to be accepted (default 819200)

Genesis Configuration

We strongly suggest to limit the max block gas in the genesis and not use the default value (-1 for infinite).

  "consensus_params": {
    "block": {
      "max_gas": "SET_YOUR_MAX_VALUE",

Tip: if you want to lock this down to a permisisoned network, the following script can edit the genesis file to only allow permissioned use of code upload or instantiating. (Make sure you set app.ProposalsEnabled=true in this binary):

sed -i 's/permission": "Everybody"/permission": "Nobody"/' .../config/genesis.json
