Liquidation Helpers

Helpers smart contracts

Verify contracts

For contracts deployed on the Osmosis chain

Install Osmosisd
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.

Download the wasm from the chain.

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

Verify that the diff is empty between them. If any value is returned, then the wasm files differ.
```
diff artifacts/$CONTRACTNAME.wasm download.wasm
```

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
