+**The [invoice form :pencil:](https://docs.google.com/forms/d/e/1FAIpQLSfmNYaoCgrxyhzgoKQ0ynQvnNRoTmgApz9NrMp-hd8mhIiO0A/viewform) has been filled out correctly for this milestone and the delivery is according to the official [milestone delivery guidelines](https://github.com/w3f/Grants-Program/blob/master/docs/Support%20Docs/milestone-deliverables-guidelines.md).**  
+
+* **[Application Document](https://github.com/w3f/Grants-Program/blob/master/applications/CosmWasmVM-CoreProduct.md)**
+* **Milestone Number:**  1
+
+**Context** (optional)
+This document is for the submission of the first milestone for the CosmWasm VM implementation in Polkadot SDK (previously known as Substrate).
+
+The CosmWasm VM uses [parity-wasmi](https://github.com/paritytech/wasmi) as interpeter,
+and [cosmwasm-sdk](https://github.com/CosmWasm/cosmwasm/) for interface types. It is 
+used to produce CosmWasm VM capable of running CosmWasm contracts which are runnable by reference `wasmd` (wasmd is a GO module for Cosmos chains with AOT native complication for CW contracts).
+
+All features are supported (as defined by CosmWasm SDK feature flags).
+
+[Pallet-cosmwasm](https://github.com/ComposableFi/composable/tree/main/code/parachain/frame/cosmwasm) integrates CW with Substrate storage, RPC, [CLI](https://github.com/ComposableFi/composable/tree/main/code/parachain/frame/cosmwasm/cli) and PolkadotJS. 
+
+PolkadotJS or the CLI can be used to execute transactions and qeury contract state.

+|  1a   | Development  | [Core Pallet](https://github.com/ComposableFi/composable/tree/main/code/parachain/frame/cosmwasm) | 
+| 1b    | Development | Any pallet can be called via precompile contracts (CosmWasm messaging interface for pallets as if thry were usual contracts). XCM can be called via [this precompile](https://github.com/ComposableFi/composable/blob/main/code/xcvm/lib/core/src/transport/xcm/mod.rs), Pallet src has [Fuzzing test](https://github.com/ComposableFi/composable/tree/main/code/parachain/frame/cosmwasm/fuzz_targets)  
+1c    | Testing | Benchamrks for pallet extrinics and gas metering of WASM instuctions are done using parity benchmarking infrastucture. You can run our devnet via the docker file or running `nix run composable#devnet-picasso` - Guide for running the CLI on a local network included in the CLI docs. CW20(analog of ERC-20) contract and 2 Composable contracts are embedded into genesis. VM can be tested via `cargo test`, examples of tests are [here](https://github.com/ComposableFi/cosmwasm-vm/blob/main/orchestrate/README.md), run of contracts in simulator and asserts of results. |
+
+**Additional Information**
+
+For the ease of checking, you can interact with CosmWasm contracts on Picasso rococo in addition to a local network.
