Liquidation Helpers

Helpers smart contracts

Verify contracts

For contracts deployed on the Osmosis chain

1. Install Osmosisd

2. Get the wasm binary executable on your local machine.

   git clone https://github.com/mars-protocol/liquidaiton-helpers.git
   git checkout <commit-id>
   cargo make rust-optimizer

   Note: Intel/Amd 64-bit processor is required. While there is experimental ARM support for CosmWasm/rust-optimizer, it's discouraged to use in production and the wasm bytecode will not match up to an Intel compiled wasm file.

3. Download the wasm from the chain.

   osmosisd query wasm code $CODEID -- $NODE download.wasm

4. Verify that the diff is empty between them. If any value is returned, then the wasm files differ.

   diff artifacts/$CONTRACTNAME.wasm download.wasm

5. Alternatively, compare the wasm files' checksums:

   sha256sum artifacts/$CONTRACTNAME.wasm download.wasm

Environment set up

• Install rustup. Once installed, make sure you have the wasm32 target:

  rustup default stable
  rustup update stable
  rustup target add wasm32-unknown-unknown

• Install cargo-make

  cargo install --force cargo-make

• Install Docker

• Install Node.js v16

• Install Yarn

• Create the build folder:

  yarn build

• Compile all contracts:

  cargo make rust-optimizer

• Formatting:

  yarn format
  yarn lint

This compiles and optimizes all contracts, storing them in /artifacts directory along with checksum.txt which contains sha256 hashes of each of the .wasm files (The script just uses CosmWasm's rust-optimizer).

Note: Intel/Amd 64-bit processor is required. While there is experimental ARM support for CosmWasm/rust-optimizer, it's discouraged to use in production.

Schemas

cargo make --makefile Makefile.toml generate-all-schemas

Creates JSON schema files for relevant contract calls, queries and query responses (See: cosmwams-schema).

Deployment

Everything related to deployment must be ran from the scripts directory:

For the Osmosis Outpost:

cd scripts
# for testnet deployment:
yarn deploy:osmosis-testnet

# for mainnet deployment:
yarn deploy:osmosis-mainnet

Deployments

osmosis-1

TBD

osmo-test-4
