Anchor Money Market Contracts

A Rust and CosmWasm implementation of the Anchor Protocol money market on the Terra blockchain.

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

Dependencies

Money Market has dependencies on Anchor Token Contracts and bAsset Contracts.

Contracts

Contract	Reference	Description
`overseer`	doc	Manages money market overalls, stores borrower information
`market`	doc	Handles Terra stablecoin deposits and borrows, ANC distribution to borrowers
`custody_bluna`	doc	Handles bLuna collateral deposits and withdrawals
`custody_beth`	doc	Handles bEth collateral deposits and withdrawals
`interest_model`	doc	Calculates the current borrow interest rate based on the market situation
`distribution_model`	doc	Calculates the borrower ANC emission rate based on the previous emission rate
`oracle`	doc	Provides a price feed for bAsset collaterals
`liquidation`	doc	OTC exchange contract for bAsset collateral liquidations

Development

Environment Setup

Rust v1.44.1+
wasm32-unknown-unknown target
Docker

Install rustup via https://rustup.rs/
Run the following:

rustup default stable
rustup target add wasm32-unknown-unknown

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:0.11.5

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