# PoE Contracts

This repo maintains contracts and support libraries for building the Tgrade PoE contracts.

These are **not** available under an open source license, you need permission from Confio to use them.

It is organized like [`cosmwasm-plus`](https://github.com/CosmWasm/cosmwasm-plus). You can use that as a reference.

## 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:0.12.4

```

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`

## Creating a new contract

You can start with [cosmwasm-template](https://github.com/CosmWasm/cosmwasm-template) as a basis:

```bash

cd contracts

cargo generate --git https://github.com/CosmWasm/cosmwasm-template.git --name CONTRACT_NAME

cd CONTRACT_NAME

# remove unneeded files

rm -rf .circleci .github .git

rm .cargo-ok .editorconfig .gitignore rustfmt.toml

rm Developing.md Importing.md Publishing.md LICENSE NOTICE

# regenerate schema for CI tests

cargo schema

git add .

```

Then add it to CI, by editing `.circleci/config.yml`. Just copy the `contract_tgrade_dso` section and

rename it, pointing to your new contract.

Finally, update `Cargo.toml` to use the current version used by all other contracts in this repo.

## Debugging

Sometimes errors might be not helpful enough, or actual error with vague description might come from

depths of other tgrade or cosmwasm related dependencies.

In such case you might want to check backtraces.

Make sure you have `nightly` installed:

```bash

$ rustup install nightly

```

and then run:

```bash

$ RUST_BACKTRACE=1 cargo +nightly test --features backtraces

```

to get more detailed backtraces.
