- Rust v1.44.1+

Install
rustupvia https://rustup.rs/ -
Run the following:
rustup default stable
rustup target add wasm32-unknown-unknown- Make sure Docker is installed.
Each contract contains Rust unit and integration tests embedded within the contract source directories. You can run:
cargo unit-testAfter making sure tests pass, you can compile each contract with the following:
RUSTFLAGS='-C link-arg=-s' cargo wasm
cp ../../target/wasm32-unknown-unknown/release/cw1_subkeys.wasm .
ls -l cw1_subkeys.wasm
sha256sum cw1_subkeys.wasmFor production builds, run the following:
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:0.12.6This performs several optimizations which can significantly reduce the final size of the contract binaries, which will be available inside the artifacts/ directory.
