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

Currently, Cosm-orc works by accessing a local cosmos chain binary, ex: junod. Support for Rust Cosmos-SDK coming soon.

Quick Start

   use anyhow::Result;
   use cosm_orc::{
       config::cfg::Config,
       orchestrator::cosm_orc::{CosmOrc, WasmMsg},
   };
   use cw20_base::msg::{ExecuteMsg, InstantiateMsg, QueryMsg};

   fn main() -> Result<()> {
       // juno_cfg.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("./examples/juno_local.yaml")?);

       let msgs: Vec<WasmMsg<InstantiateMsg, ExecuteMsg, QueryMsg>> = vec![
           WasmMsg::InstantiateMsg(InstantiateMsg {
               name: "Meme Token".to_string(),
               symbol: "MEME".to_string(),
               decimals: 6,
               initial_balances: vec![],
               mint: None,
               marketing: None,
           }),
           WasmMsg::QueryMsg(QueryMsg::TokenInfo {}),
       ];

       cosm_orc.process_msgs("cw20_base".to_string(), &msgs)?;

       Ok(())
 }
