## General Resources



- [The CosmWasm book](https://book.cosmwasm.com/) - a step-by-step guide to

  writing CosmWasm smart contracts.

- [CosmWasm framework](https://github.com/CosmWasm/cosmwasm) - a "core" CosmWasm

  repo. This includes the core Rust framework for writing a smart contract, a

  virtual machine that runs smart contracts and is embedded in any chain running

  them, the IDL format for describing the interface of a smart contract, and

  more! A few of these are commonly dependencies of smart contracts.

- [CosmWasm template](https://github.com/CosmWasm/cw-template) - a template for

  getting an empty smart contract up and running quickly. Instructions included!



## CosmWasm Framework



- [cosmwasm-std](https://crates.io/crates/cosmwasm-std)

  ([repo](https://github.com/CosmWasm/cosmwasm/tree/master/packages/std)): The

  standard library for building CosmWasm smart contracts. Code in this package

  is compiled into the smart contract.

- [cw-storage-plus](https://crates.io/crates/cw-storage-plus)

  ([repo](https://github.com/CosmWasm/cw-storage-plus)): Helper methods to

  reduce boilerplate for storing data types. Easier and more secure persistence

  layer.

- [cosmwasm-schema](https://crates.io/crates/cosmwasm-schema)

  ([repo](https://github.com/CosmWasm/cosmwasm/tree/master/packages/schema)): A

  dependency for CosmWasm contracts to generate the IDL (interface description)

  files. These are consumed e.g. by

  [`ts-codegen`](https://github.com/CosmWasm/ts-codegen) to automagically get a

  _TypeScript_ client for your contract.

- [cw-multi-test](https://crates.io/crates/cw-multi-test)

  ([repo](https://github.com/CosmWasm/cw-multi-test)):



## Smart Contract Libraries



- [cw-utils](https://crates.io/crates/cw-utils)

  ([repo](https://github.com/CosmWasm/cw-utils)): A collection of (somewhat

  random) helpers we found useful when developing `cw-plus` contracts and specs.

  Available as a library at crates.io!

- [cw-coins](https://crates.io/crates/cw-coins)

  ([repo](https://github.com/steak-enjoyers/cw-plus-plus)): A helper for

  managing multiple coins in a smart contract.

- [cw-item-set](https://crates.io/crates/cw-item-set)

  ([repo](https://github.com/steak-enjoyers/cw-plus-plus)): A `HashSet`

  equivalent (set of unique items) that can be stored in smart contract storage.



## Smart Contracts



Before you create a PR to add your contract here, read the

[publishing guidelines](https://github.com/confio/cosmwasm-template/blob/master/Publishing.md)

and make sure you complete them all, specifically adding an OSI-approved license

and checking in valid artifacts for the build (`contract.wasm`,

`schema/*.json`).



We do validate the artifacts and perform a basic code review of contracts

included in this list. However, nothing terribly comprehensive and inclusion

here should not be taken in lieu of a proper audit. We do provide some

guidelines on

[sharing code reviews in a decentralized manner](https://github.com/confio/cosmwasm-template/blob/master/Importing.md)

which can be used as the basis for a peer-reviewed audit.



### `cw-plus` Specifications and Examples



[The `cw-plus` repo](https://github.com/CosmWasm/cosmwasm-plus) houses both

protocol specifications and their reference implementations. These

implementations are meant both as examples of production-ready contracts and

pieces you might like to use in your project as they are.



#### Specifications



- [cw1](https://github.com/CosmWasm/cosmwasm-plus/tree/master/packages/cw1) -

  proxy contracts that are meant to forward a message (probably after checking

  the sender against some form of access control), this time with the contract

  as the sender.

- [cw2](https://github.com/CosmWasm/cw-plus/tree/main/packages/cw2) - contract

  metadata (name and version) that can be inspected directly, without querying

  the contract.

- [cw3](https://github.com/CosmWasm/cosmwasm-plus/blob/master/packages/cw4/README.md) -

  multisig and voting.

- [cw4](https://github.com/CosmWasm/cosmwasm-plus/blob/master/packages/cw4/README.md) -

  group membership management with weights.

- [cw20](https://github.com/CosmWasm/cosmwasm-plus/tree/master/packages/cw20) -

  fungible token.



#### Reference implementations



- [cw1-whitelist](https://github.com/CosmWasm/cosmwasm-plus/tree/master/contracts/cw1-whitelist)

  by [ethanfrey](https://github.com/ethanfrey): This may be the simplest

  implementation of

  [cw1](https://github.com/CosmWasm/cosmwasm-plus/tree/master/packages/cw1), a

  whitelist of addresses. It contains a set of admins that are defined upon

  creation. Any of those admins may Execute any message via the contract, per

  the [CW1](https://github.com/CosmWasm/cosmwasm-plus/tree/master/packages/cw1)

  spec.

- [cw1-subkeys](https://github.com/CosmWasm/cosmwasm-plus/tree/master/contracts/cw1-subkeys)

  by [ethanfrey](https://github.com/ethanfrey): This builds on cw1-whitelist to

  provide the first non-trivial solution. It still works like cw1-whitelist with

  a set of admins (typically 1) which have full control of the account. However,

  you can then grant a number of accounts allowances to send native tokens from

  this account.

- [cw3-fixed-multisig](https://github.com/CosmWasm/cosmwasm-plus/tree/master/contracts/cw3-fixed-multisig):

  This is a simple implementation of the

  [cw3 spec](https://github.com/CosmWasm/cosmwasm-plus/blob/master/packages/cw4/README.md).

  It is a multisig with a fixed set of addresses created upon initialization.

  Each address may have the same weight (K of N) or some may have extra voting

  power.

- [cw3-flex-multisig](https://github.com/CosmWasm/cosmwasm-plus/tree/master/contracts/cw3-flex-multisig):

  This builds on cw3-fixed-multisig with a more powerful implementation of the

  cw3 spec. It is a multisig contract that is backed by a

  [cw4](https://github.com/CosmWasm/cosmwasm-plus/tree/master/packages/cw4)

  (group) contract, which independently maintains the voter set.

- [cw4-group](https://github.com/CosmWasm/cosmwasm-plus/tree/master/contracts/cw4-group):

  This is a basic implementation of the

  [cw4 spec](https://github.com/CosmWasm/cosmwasm-plus/blob/master/packages/cw4/README.md).

  It fulfills all elements of the spec, including the raw query lookups, and it

  designed to be used as a backing storage for cw3 compliant contracts.

- [cw4-stake](https://github.com/CosmWasm/cosmwasm-plus/tree/master/contracts/cw4-stake):

  This is a second implementation of the

  [cw4 spec](https://github.com/CosmWasm/cosmwasm-plus/blob/master/packages/cw4/README.md).

  It fufills all elements of the spec, including the raw query lookups, and it

  is designed to be used as a backing storage for cw3 compliant contracts.

- [cw20-base](https://github.com/CosmWasm/cosmwasm-plus/tree/master/contracts/cw20-base)

  by [ethanfrey](https://github.com/ethanfrey): Basic implementation of a

  [cw20](https://github.com/CosmWasm/cosmwasm-plus/tree/master/packages/cw20)

  contract. It implements the

  [cw20](https://github.com/CosmWasm/cosmwasm-plus/blob/master/packages/cw20/README.md)

  spec and is designed to be deloyed as is, or imported into other contracts to

  easily build cw20-compatible tokens with custom logic.



### Other Contracts



These contracts demonstrate best practices and learning references. Please do

not use them in production as is. You are welcome to fork them, and

independently review, refine and audit them, using them as a basis for your

protocol. Or just as inspiration



- [cw-tokens](https://github.com/CosmWasm/cw-tokens) - a few other

  [cw20](https://github.com/CosmWasm/cosmwasm-plus/tree/master/packages/cw20)

  (fungible token) contracts.

- [cw-nfts](https://github.com/CosmWasm/cw-nfts) - non-fungible tokens. Official

  repository for all work on NFT standards and reference contracts. This is

  where the

  [`cw721 spec`](https://github.com/CosmWasm/cw-nfts/tree/main/packages/cw721)

  lives.
