Cosmwasm

• Beaker's guideline*
  • play along with the example would be the quickest way to get started with cosmwasm
  • can use Beaker for the rest of the excercise
• cosmwasm book*
  • very helpful, especially explanation in the actor model section
• terra academy: cosmwasm (video / excercise) *
  • not a comprehensive course, but good starting point, some part might be outdated but the idea persist
• wasmd
• wasmvm spec

What is Protostar SDK

CosmWasm is multi-chain smart contract platform building for Cosmos ecosystem. While being powerful as it is, a lot of things needs to be wired manually when developing CosmWasm contracts and dapps. To provide seamless CosmWasm development experience, Protostar is designed to be a swiss-army knife for building custom dev tool for CosmWasm on each specific blockchain.

What is Membrane

Membrane will use Protostar SDK to build development toolset that specializes in developing CosmWasm on Osmosis. Optimize for deeper integration with Osmosis to facilitate building the best dapps that really augment Osmosis, not just any dapps possible; for example:

• testing/simulation for IBC and Bridges interaction
• deep integration with LP interaction

Overview

Terrain is a Terra development environment for better smart contract development experience.

Terrain will help:

• scaffold your dapp project
• ease the development and deployment process
• create custom task for blockchain and contract interaction with less boilerplate code
• using terra.js directly could be cumbersome, Terrain gives you extensions and utilities to help you
