What you will learn:

This workshop introduces our newest tools for CosmWasm developers for all Cosmos chains. We provide a Hardhat-like simulation environment to fully do smart contracts integration tests with dApps beyond simple functional tests (unit tests). You can use the environment to mock IBC channels & functionalities, snapshot current block states of Cosmos chains, or do metering for gas optimization. This environment is a complete tool and will save much of your time!

- Configure multiple host chain environments with chain-specific settings/state

- Multiple simultaneous contract instances can exist per chain

- Chain modules can be simulated through custom user code

- Extensible for further instrumentation via custom middleware

- Load fork state from running blockchain
