Lido Terra Contracts

This monorepository contains the source code for the smart contracts implementing bAsset Protocol on the Terra blockchain.

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

Contracts

Development

Environment Setup

  • Rust v1.55.0+
  • 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 tests embedded within the contract source directories. You can run:

cargo test unit-test
cargo test 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:0.11.5

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