Anchor Token (ANC) Contracts

This monorepository contains the source code for the Money Market smart contracts implementing Anchor Protocol on the Terra blockchain.

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

Dependencies

Anchor Token depends on Terraswap and uses its implementation of the CW20 token specification.

Contracts

Contract Reference Description
airdrop doc Holds ANC tokens which are to be used Luna staker incentives
collector doc Accumulates protocol fees, converts them to ANC and distributes to ANC stakers
community doc Manages ANC community grants
distributor doc Holds ANC tokens which are to be used as borrower incentives
gov doc Handles Anchor Governance and reward distribution to ANC stakers
staking doc Handles ANC-UST pair LP token staking
vesting doc Holds ANC tokens which are to be used ANC token allocation vesting

Development

Environment Setup

  • Rust v1.44.1+
  • 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:0.11.5

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