This proposal is the fourth of our quarterly submissions by OpenZeppelin to accelerate the development and deployment of secure parachains in the Polkadot ecosystem. Since our last approval in July 2024, we have achieved:
<ul>
<li>The launch of an <a href="https://github.com/orgs/OpenZeppelin/projects/32/views/3">EVM Runtime Template</a> configured with Frontier pallets to support Solidity smart contracts seamlessly on Substrate chains.</li>
<li>A detailed <a href="https://docs.openzeppelin.com/substrate-runtimes/guides/contract_migration" target="_blank" rel="noopener">developer guide</a> to assist in migrating Solidity contracts from Ethereum to our EVM runtime template.</li>
<li>Collaboration with R0gue to <a href="https://github.com/r0gue-io/pop-cli/releases/tag/v0.2.0" target="_blank" rel="noopener">integrate Pop CLI</a> with our templates to give developers an even easier experience.</li>
<li>Account abstraction support and pre-deployed contracts.</li>
</ul>
In this fourth phase (M4) we request the funding to:
<ul>
<li>Meta Pallets: Streamline developer experience by creating higher-level, opinionated "meta pallets" that encapsulate common pallet functionalities. This reduces the number of pallets required for a project, simplifying development and accelerating time-to-market.</li>
<li>Tanssi Integration: Enhance developer experience and increase parachain launch time by making our templates compatible with Tanssi.</li>
<li>Zombienet-sdk improvements: One issue we&rsquo;ve faced when writing integration tests is being able to easily spin up a local chain and tear it up. After speaking with some teams we realized this is a common problem across the ecosystem, that&rsquo;s why we are collaborating with Parity to improve DX for zombienet by contributing upstream. An initial iteration for this design can be found <a href="https://github.com/paritytech/zombienet-sdk/pull/261" target="_blank" rel="noopener">here</a>.</li>
<li>Snowbridge Integration: Snowbridge is a general purpose, trustless and decentralized bridge between Polkadot and Ethereum. Our goal is to include out of the box support for parachains that use our templates.</li>
<li>Developer guides detailing the use of Meta Pallets and all new features.</li>
</ul>
We aim to maintain transparent progress and welcome community feedback to strengthen the Polkadot network.

OpenZeppelin x Polkadot Ecosystem Growth Phase M4

Treasury

Propose and approve a spend of treasury funds.

## Dispatch Origin

Must be [`Config::SpendOrigin`] with the `Success` value being at least
`amount` of `asset_kind` in the native asset. The amount of `asset_kind` is converted
for assertion using the [`Config::BalanceConverter`].

## Details

Create an approved spend for transferring a specific `amount` of `asset_kind` to a
designated beneficiary. The spend must be claimed using the `payout` dispatchable within
the [`Config::PayoutPeriod`].

### Parameters
- `asset_kind`: An indicator of the specific asset class to be spent.
- `amount`: The amount to be transferred from the treasury to the `beneficiary`.
- `beneficiary`: The beneficiary of the spend.
- `valid_from`: The block number from which the spend can be claimed. It can refer to
  the past if the resulting spend has not yet expired according to the
  [`Config::PayoutPeriod`]. If `None`, the spend can be claimed immediately after
  approval.

## Events

Emits [`Event::AssetSpendApproved`] if successful.

- **Problem Statement:** OpenZeppelin aims to accelerate the development and deployment of secure parachains in the Polkadot ecosystem.
- **Significance:** Enhancing developer experience, reducing pallets required for projects, and increasing parachain launch time.
- **Proposed Solution:** Funding requested for creating meta pallets, Tanssi integration, Zombienet-sdk improvements, Snowbridge integration, and developer guides.
- **Expected Outcomes:** Streamlined developer experience, simplified development, faster time-to-market, and enhanced support for parachains using OpenZeppelin's templates.
