This repo is a collection of contracts built with the cosmwasm framework. Anyone building on cosmwasm is encouraged to submit their contracts as a sub-project via a PR.
The organization is relatively simple. The top-level directory is just a placeholder and has no real code. And we use workspaces to add multiple contracts below. This allows us to compile all contracts with one command.
The following contracts are available for use. You can view the source code under src
and a precompiled wasm ready for deployment under contract.wasm. Take a look here:
- escrow - A basic escrow with timeout and partial release
If you want to add a contract, first fork this repo and create a branch for your PR. I suggest setting it up via cosmwasm-template:
cargo generate --git https://github.com/confio/cosmwasm-template.git --name FOO
Make sure it is listen in Cargo.toml:
[workspace]
members = ["FOO", "...."]And fix up the reference in tests/integration.rs by adding one more .. to the target directory:
From: static WASM: &[u8] = include_bytes!("../target/wasm32-unknown-unknown/
To: static WASM: &[u8] = include_bytes!("../../target/wasm32-unknown-unknown/
Once you add this, you can start writing your code and testing it.
Before you merge the code, make sure it builds and passes all tests, both in the package,
and when calling it from the root packages cargo wasm && cargo test. This should
show your package is covered by the CI.
You should also prepare a compiled contract.wasm before each merge to master.
This is not enforced by the CI (a full build each commit), but should be tested
on merge. To validate:
sha256sum contract.wasm
rm contract.wasm
docker run --rm -u $(id -u):$(id -g) -v $(pwd):/code confio/cosmwasm-opt:0.4.1
sha256sum contract.wasmIf the sha256 hash changes, then please commit the new version. And if the sha256 hash changes without any code changes, then please submit an issue on cosmwasm-opt.
Once you pass these checks, please open a PR on this repo.
