Cosm-Orc

Rust Cosmwasm smart contract orchestration 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.

Potential uses: * Integration tests * Deployments / Bootstrapping environments * Gas profiling

This project is not yet intended to be used for mainnet.

Quick Start

``rust // juno_local.yaml has thecw20basecode_id already stored // If the smart contract has not been stored on the chain yet use:cosmorc::storecontracts()` let mut cosmorc = CosmOrc::new(Config::fromyaml("./example-configs/junolocal.yaml")?, false)?; let key = SigningKey { name: "validator".tostring(), key: Key::Mnemonic("word1 word2 ...".tostring()), };

cosmorc.instantiate( "cw20base", "memetokentest", &InstantiateMsg { name: "Meme Token".tostring(), symbol: "MEME".tostring(), decimals: 6, initial_balances: vec![], mint: None, marketing: None, }, &key, )?;

let res = cosmorc.query( "cw20base", &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(): ```rust let mut cosmorc = CosmOrc::new(Config::fromyaml("./example-configs/junolocal.yaml")?, false)?; let key = SigningKey { name: "validator".tostring(), key: Key::Mnemonic("word1 word2 ...".to_string()), };

// Build + optimize all smart contracts in current workspace // This will save the optimized wasm files in ./artifacts cosmorc.optimizecontracts("./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: cosmorc.storecontracts("./artifacts", &key)?;

let res = cosmorc.query( "cw20base", &QueryMsg::TokenInfo {}, )?; let res: TokenInfoResponse = res.data()?; ```

Gas Profiling

```rust let mut cosmorc = CosmOrc::new(Config::fromyaml("config.yaml")?, true)?;

let reports = cosmorc.gasprofiler_report(); ```
