Cosmwasmception

Running

Fastest way to run this contract would be through our vm. But note that our vm runs an already built version this contract, so follow building guidelines to build and run if you want to make any changes.

Clone the vm.

# Clone our vm
git clone git@github.com:ComposableFi/cosmwasm-vm.git
# Workshop branch contains some modifications to be able
# to upload and run contracts that are over 200kb xd.
git checkout workshop

Run it.

cargo test --profile=release --features=iterator --package cosmwasm-vm-wasmi semantic::test_workshop -- --exact

Few important notes

• release profile should be enabled, otherwise it will take a lot to run.
• The test to run the workshop is test_workshop in vm-wasmi/src/semantic.rs, you can tweak it however you like.

Building

RUSTFLAGS='-C link-arg=-s' cargo b --target=wasm32-unknown-unknown --profile release

• RUSTFLAGS are used to reduce the binary size.

• Our vm uses the contract in its fixtures directory. So either copy the output contract to there:

cp $PATH_TO_COSMWASMCEPTION/target/wasm32-unknown-unknown/release/cosmwasmception.wasm $PATH_TO_COSMWASM_VM/fixtures/

Or just change the file path in test_workshop.
