Cosm-Orc

Rust Cosmwasm smart contract integration testing and gas profiling library.

Store, instantiate, execute, and query Cosmwasm smart contracts against a configured Cosmos based chain.

Optionally, profile gas usage of the smart contract operations.

If you need a more general Cosmos SDK client library try cosm-tome, which we use here under the hood.

Potential uses:

• Integration tests
• Deployments / Bootstrapping environments
• Gas profiling
• Realistic adversarial testing

This project is not intended to be used for mainnet.

Quick Start

// juno_local.yaml has the `cw20_base` code_id already stored
// If the smart contract has not been stored on the chain yet use: `cosm_orc::store_contracts()`
let mut cosm_orc = CosmOrc::new(Config::from_yaml("./example-configs/juno_local.yaml")?, false)?;
let key = SigningKey {
   name: "validator".to_string(),
   key: Key::Mnemonic("word1 word2 ...".to_string()),
   derivation_path: "m/44'/118'/0'/0/0".to_string(),
};

cosm_orc.instantiate(
   "cw20_base",
   "meme_token_test",
   &InstantiateMsg {
       name: "Meme Token".to_string(),
       symbol: "MEME".to_string(),
       decimals: 6,
       initial_balances: vec![],
       mint: None,
       marketing: None,
   },
   &key,
   None,
   vec![]
)?;

let res = cosm_orc.query(
   "cw20_base",
   &QueryMsg::TokenInfo {},
)?;
let res: TokenInfoResponse = res.data()?;

See here for example usages.

Optimize and Store Contracts

If config.yaml doesn't have the pre-stored contract code ids, you can call optimize_contracts() and store_contracts():

let mut cosm_orc = CosmOrc::new(Config::from_yaml("./example-configs/juno_local.yaml")?, false)?;
let key = SigningKey {
   name: "validator".to_string(),
   key: Key::Mnemonic("word1 word2 ...".to_string()),
   derivation_path: "m/44'/118'/0'/0/0".to_string(),
};

// Build + optimize all smart contracts in current workspace
// This will save the optimized wasm files in `./artifacts`
cosm_orc.optimize_contracts("./Cargo.toml")?;

// NOTE: currently cosm-orc is expecting a wasm filed called: `cw20_base.wasm`
// to be in `/artifacts`, since `cw20_base` is used as the contract name in the instantiate()/query() calls below:
cosm_orc.store_contracts("./artifacts", &key, None)?;

cosm_orc.instantiate(
   "cw20_base",
   "meme_token_test",
   &InstantiateMsg {
       name: "Meme Token".to_string(),
       symbol: "MEME".to_string(),
       decimals: 6,
       initial_balances: vec![],
       mint: None,
       marketing: None,
   },
   &key,
   None,
   vec![]
)?;

let res = cosm_orc.query(
   "cw20_base",
   &QueryMsg::TokenInfo {},
)?;
let res: TokenInfoResponse = res.data()?;

Gas Profiling

let mut cosm_orc = CosmOrc::new(Config::from_yaml("config.yaml")?, true)?;

cosm_orc.instantiate(
   "cw20_base",
   "meme_token_test",
   &InstantiateMsg {
       name: "Meme Token".to_string(),
       symbol: "MEME".to_string(),
       decimals: 6,
       initial_balances: vec![],
       mint: None,
       marketing: None,
   },
   &key,
   None,
   vec![]
)?;

let reports = cosm_orc.gas_profiler_report();
