# CosmWasm Tokens



[![CircleCI](https://circleci.com/gh/CosmWasm/cw-plus/tree/master.svg?style=shield)](https://circleci.com/gh/CosmWasm/cw-plus/tree/master)



This is a collection of [cw20-related](https://github.com/CosmWasm/cw-plus/blob/main/packages/cw20/README.md) contracts

extracted from [cw-plus](https://github.com/CosmWasm/cw-plus). These serve as examples of what is possible to build

and as starting points for your own CosmWasm token contracts.



None of these have been audited or are considered ready-for-production as is. Contributions may come from many

community members. Please do your own due dilligence on them before using on any production site, and please

[raise Github issues](https://github.com/CosmWasm/cw-tokens/issues) for any bugs you find.



You are more than welcome to [create a PR](https://github.com/CosmWasm/cw-tokens/pulls) to add any cw20-related

contract you have written that you would like to share with the community.

**Warning** None of these contracts have been audited and no liability is

assumed for the use of this code. They are provided to turbo-start

your projects.



## Contracts



All contracts add functionality around the CW20 Fungible Token standard:



* [`cw20-atomic-swap`](./contracts/cw20-atomic-swap) an implementation of atomic swaps for

both native and cw20 tokens.

* [`cw20-bonding`](./contracts/cw20-bonding) a smart contract implementing arbitrary bonding curves,

which can use native and cw20 tokens as reserve tokens.

* [`cw20-staking`](./contracts/cw20-staking) provides staking derivatives,

staking native tokens on your behalf and minting cw20 tokens that can

be used to claim them. It uses `cw20-base` for all the cw20 logic and

only implements the interactions with the staking module and accounting

for prices.

* [`cw20-escrow`](./contracts/cw20-escrow) is a basic escrow contract

(arbiter can release or refund tokens) that is compatible with all native

and cw20 tokens. This is a good example to show how to interact with

cw20 tokens.

* [`cw20-merkle-airdrop`](./contracts/cw20-merkle-airdrop) is a contract

  for efficient cw20 token airdrop distribution.



## Compiling



To compile all the contracts, run the following in the repo root:



```

docker run --rm -v "$(pwd)":/code \

  --mount type=volume,source="$(basename "$(pwd)")_cache",target=/code/target \

  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \

  cosmwasm/workspace-optimizer:0.12.8

```



This will compile all packages in the `contracts` directory and output the

stripped and optimized wasm code under the `artifacts` directory as output,

along with a `checksums.txt` file.



If you hit any issues there and want to debug, you can try to run the

following in each contract dir:

`RUSTFLAGS="-C link-arg=-s" cargo build --release --target=wasm32-unknown-unknown --locked`
