+# Substrate Move System Pallet (part 2)
+
+- **Team Name:** Eiger
+- **Payment Address:** Fiat 14.04.2023, 16:50 UTC+3
+- **Level:** 3
+
+## Project Overview ****📄****
+
+This application is a response to **[Move Smart Contract Pallet RFP](https://github.com/w3f/Grants-Program/blob/master/docs/RFPs/Open/move_smart_contract_pallet.md)** and a follow-up to our [previous work](https://github.com/w3f/Grants-Program/pull/1769) on the RFP.
+
+### Overview
+
+> 📖 Terminology:
+**Substrate Move System Pallet** - A Substrate system pallet that can be used as a building block for substrate-based chains, it exposes interfaces to interact with the Move virtual machine.
+**Substrate Move** - A Move language fork that is Substrate compatible.
+
+- The goal is to provide a Substrate system pallet that allows to deploy and interact with Smart Contracts written in the Move language, by providing a Move Virtual Machine (MoveVM) as a pallet.
+- The project directly improves the growth potential of the Substrate based ecosystem by providing support for one of the most modern smart contract programming languages and VM types out there - Move.
+- We are interested in creating this project because we are firm believers in the modular vision of web3, and only by collaborative efforts on improving and unifying the technology between different chains and the languages, will we get better products as an outcome.
+
+**Goal** - Level up the growth possibilities of the Substrate ecosystem by providing a way to develop and execute Move smart contracts on Substrate.
+
+This is the second phase of a 3-phase development plan:
+
+1. In-Depth Exploration and Assessment of MoveVM and Substrate Integration
+2. **MoveVM compatibility work and Subtrate Pallet development**
+3. Finalising the Substrate-Compatible MoveVM
+
+### Project Details
+
+**Prior work**
+
+We are basing the core architecture and many of the design decisions on the [Pontem networks developed system pallet for Move VM](https://github.com/pontem-network/pontem/tree/master/pallets/sp-mvm). They had maintained [their own fork of the Diem Move language](https://github.com/pontem-network/sp-move-vm), which was used as the base execution layer for their version. Both of these repositories have not been maintained for a very long time already.
+
+♻️ We aren't seeking to maintain any of the existing codebase; rather, we aim for a full revival through a new greenfield project. Our rationale for this stems from the substantial advancements made in the Rust, Substrate, and Move ecosystems since Pontem’s latest commits from over a year ago. We believe that handling potential code rot due to the passage of time might be more labor-intensive than starting afresh and drawing upon existing projects for more current guidelines.
+
+**Documentation of core components, architecture**
+
+1. **Substrate Move:**
+
+    The first part of the project will be a MoveVM fork, as some major changes will need to be made to the codebase for it to be substrate compatible. For example:
+
+    - `no_std` compatibility: Making it lightweight and suitable for use in Substrate runtimes.
+    - `wasm32` target compatibility: Adapting all the VM’s different components to work efficiently and securely on the wasm32 target architecture.
+
+    We created the fork of Move VM in a manner that allow us and the community to easily follow and track changes from the upstream, thus making the maintenance and change tracking to be much simpler.
+
+2. **Move VM system pallet:**
+
+    The second part of the project will be a Substrate virtual machine pallet in Substrate. This is a modular component that is needed to integrate a specific new VM into a Substrate runtime. It will serve as a bridge between the runtime and the Move VM, managing resources and translating data or actions between the two environments.
+
+
+**API specifications**
+
+As a minimum, we plan on providing all of the RPC calls that the Pontem crate did. As the team progresses with the implementation, we might add or remove RPC calls as we best see fit.
+
+Move language has a concept of “gas” for executing contracts, whereas Polkadot uses “Weights”. Each Move transaction invocation requires providing a gas limit for execution, and it’s necessary to be able to transform the values between weight and gas:
+
+- `mvm_gasToWeight`
+- `mvm_weightToGas`
+
+Estimating gas for different operations:
+
+- `mvm_estimateGasPublish`
+- `mvm_estimateGasExecute`
+
+Working with the primitives of the Move language:
+
+- `mvm_getResource`
+- `mvm_getModuleABI`
+- `mvm_getModule`
+
+**Tech stack**
+
+We plan on using Rust for developing the system pallets and using existing Move language smart contracts for end-to-end testing of the whole workflow.
+
+**Notes**
+
+Because the Move language requires a fork to work with Substrate chains, and modifications to the address size, there might be incompatibilities with deploying existing Move Smart Contracts from other chains that make use of the address properties size, as well as the compiled ABI and bytecode for those contracts might be invalid. To deploy on our MoveVM system pallet, the forked toolchain must be used to re-compile all smart contracts. The address size of Move language is configurable via a feature switch with 32-bits being one of the options.
+
+### Ecosystem Fit
+
+Move is a smart contract programming language that emphasizes access control and scarcity, offering some unique advantages over other popular VMs in blockchain ecosystems.
+
+The importance of bringing the MoveVM to Polkadot was recognized over two years ago when [Pontem Network](https://pontem.network/) started working on a [Move virtual machine pallet](https://github.com/pontem-network/pontem/tree/master/pallets/sp-mvm) to execute Move smart contracts on Substrate-based chains. Although they discontinued the project and haven't updated the codebase for over a year, the W3F still keeps this RFP, which serves as evidence that porting the MoveVM is crucial for the future of the Polkadot network.
+
+We concur with this perspective and have actually been actively researching the MoveVM - exactly with a similar idea of helping port it over to other chains.

+## Future Plans
+
+This is the second phase of a 3-phase development program:
+
+1. In-Depth Exploration and Assessment of MoveVM and Substrate Integration
+2. **MoveVM compatibility work and Subtrate Pallet development**
+3. Finalising the Substrate-Compatible MoveVM
+
+The **next** step will be to submit a grant proposal to finalize this work - finishing up the pallet and making sure it works properly and can be utilized by other developers .
+
+We hope that upon the completion of all phases of creating the Substrate Move System Pallet, it will open doors for further collaboration and community input on the project. We strive to have the codebase well documented so that others might join in and contribute.
+
+While there are no long-term plans set in stone for the usage of this pallet, we have had discussions about possibly creating a parachain, possibly a common good parachain, that utilizes this MoveVM implementation and would run MoveVM contracts. As we near the completion of this initial development, we will be discussing these future plans more in-depth..
+
+## Additional Information **➕**
+
+**How did you hear about the Grants Program?**
+
+We learned about it when looking at open RFPs by the web3 foundation on their website.
+
+We wanted to get back up to date on what is happening in the Polkadot ecosystem, and working on grants, specifically RFPs, has been a great way to do so.
+
+Looking to apply to other RFPs currently open as well. Stay tuned!
