Contracts

Here are a number of useful contracts that either implement or consume the interfaces defined in packages/cw*.

Creating a new contract

Use cosmwasm-template as a basis, in particular the cw-plus branch.

cd contracts
cargo generate --git https://github.com/CosmWasm/cosmwasm-template.git --branch cw-plus --name PROJECT_NAME
cd PROJECT_NAME
rm -rf .git
rm .gitignore
rm .cargo-ok
git add .

Now, integrate it into the CI and build system

  1. Edit .circleci/config.yml, copy an existing contracts job and replace the name. Then add your new job to the jobs list on top. (eg. copy contracts_cw1_whitelist to contracts_cw721_base and then replace the 3 instances of cw1-whitelist in that job description with cw721-base. And don't forget to add contracts_cw721_base to workflows.test.jobs)

  2. Add to the ALL_CONTRACTS variable in scripts/publish.sh

  3. Set the version variable in Cargo.toml to the same version as packages/cw20. For example, "0.5.0" rather than the default "0.1.0"

  4. Edit the root Cargo.toml file and add a profile.release.package.CONTRACT_NAME section, just like profile.release.package.cw1-subkeys, but with your package name.

  5. Run cargo build && cargo test in the new contract dir

  6. Commit all changes and push the branch. Open a PR and ensure the CI runs this.
