Glow Protocol Lotto Contract

This monorepository contains the source code for the smart contract implementing Glow Lotto Protocol on the Terra blockchain.

You can find information about the architecture, usage, and function of the smart contracts on the official Glow Savings documentation site.

Dependencies

Glow Lotto depends on Anchor Protocol Contracts.

Development

Environment Setup

  • Rust v1.52.0+
  • wasm32-unknown-unknown target
  • Docker

  1. Install rustup via https://rustup.rs/

  2. Run the following:

rustup default stable
rustup target add wasm32-unknown-unknown
  1. Make sure Docker is installed

Unit / Integration Tests

Each contract contains Rust unit and integration tests embedded within the contract source directories. You can run:

cargo unit-test
cargo integration-test

Compiling

After 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.wasm

Production

For 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:0.10.4

This performs several optimizations which can significantly reduce the final size of the contract binaries, which will be available inside the artifacts/ directory.
