![01.jpg](https://i.postimg.cc/CMC2BYBG/01.jpg)

The MantaWallet team started building in Feb 2023. Since then, we have been highly focused on building fast and efficiently. Below are our achievements by the numbers:

## Tractions:

- Total Chrome Store users **215K+** [https://chrome.google.com/webstore/detail/enabgbdfcbaehmbigakijjabdpdnimlg](https://chrome.google.com/webstore/detail/enabgbdfcbaehmbigakijjabdpdnimlg)
- Manta Wallet has developed a total of **28 versions**. [https://github.com/Manta-Network/manta-extension/releases](https://github.com/Manta-Network/manta-extension/releases)
- xxx zkAddresses activated on Manta Wallet
- xxx transactions related to zk on Manta Wallet.

## Key features:

- 🔐 Create wallet accounts with both public address and zkAddress with a single mnemonic.
- ✅ Import, and persistently store the mnemonics and the derived private key.
- ✅ View public assets and zkAssets in the wallet.
- ✅ Connect to DApps and sign human-readable transactions from trusted DApps.
- ✅ zkAssets public2Private, private2Private, private2Public
- ✅ Show your recent public / private transactions

![Slide 16_9 - 20.jpg](https://i.postimg.cc/x19NfGrG/Slide-16-9-20.jpg)

## Framework Design(Kumi):

There has three parts in Chrome Extension V3 version.

- Inject script (To web site)
- Service work
- Pop up

In order to better integrate the web3 ecosystem, a set of RPC communication protocol has been designed based on PostMessage.

![framework.jpg](https://i.postimg.cc/SRQfYB3d/framework.jpg)

### Service Work Part

In Service Work, we have many things to handle, such as:

- Message listening
- Business logic
- Data storage
- Scheduled Tasks
- etc…

This looks a bit familiar, like a backend framework. Yes, we are designing a backend framework. I think everyone should be familiar with Koa.js. I borrowed Koa's ideas and designed an RPC version of the framework.

Kumi.js:

![Slide 16_9 - 21.jpg](https://i.postimg.cc/nhfMd4cb/Slide-16-9-21.jpg)

At the organizational code level, use the classic Controller & Service & Model.

![Slide 16_9 - 17.jpg](https://i.postimg.cc/RFLBGtFd/Slide-16-9-17.jpg)

Especially important, the ServiceWork will be restarted within 5 minutes at most, so there is no session in memory, and all users' data is persistence in IndexedDB/Chrome Storage.

## Manta-SDK Design & Introduction:

Manta-SDK is implemented using TS/Rust and focuses primarily on zkAddress and zkAssets functionalities. It enables operations such as Public2Private for Assets, PrivatetoPublic for zkAssets, privateTransfer, and implements features like zkNFT.

The primary aim of Manta-SDK is to provide a set of functionalities including zkAddress, zkAssets, and asset transfer operations that any wallet can easily incorporate through simple configurations. By encapsulating complex logic and offering a user-friendly API, it aims to simplify integration for developers. Currently, it supports two environments: Node and Browser.

### Functionality Overview of Manta-SDK:

1. Feature List
    - Ledger Management: Includes downloading, parsing, assembling, etc., of the Ledger.
    - BaseWallet: The foundational instance for all wallets, responsible for handling common logic.
    - PrivateWallet: The base class for all wallets, managing common wallet functions.
    - MantaPayWallet: Inherits from PrivateWallet and implements functions related to MantaPay.
    - MantaSbtWallet: Inherits from PrivateWallet and implements functions related to MantaSBT.

    - Introduce CLI support, enabling developers to operate SDK via CLI for easier debugging and development.

# 4. Why should MantaWallet be supported?

---

1. **The wallet plays a crucial role in a blockchain ecosystem**
A blockchain wallet serves as a cornerstone for any thriving ecosystem, comparable to a browser in the realm of the internet. Without a functional blockchain wallet, users have no access to ecosystem features and applications, which hinders the ecosystem's potential for growth. Therefore, the wallet is an important infrastructure for the ecosystem that should receive support for its development.
Money inherently loses value, and the same holds for DOT, which experiences an annual inflation rate of over 7%. When left static, it progressively loses value. Similar to the economic development of a country, funds need to be circulated and invested wisely, particularly in building essential infrastructure.
2. **Wallet development is resource-intensive**
Contrary to common assumptions, our treasury allocation does not equate to substantial funding. A comparative analysis with leading wallets in other ecosystems reveals the substantial investments required for wallet development.
    - **[Solana's Phantom](https://www.crunchbase.com/organization/phantom-3171)** raised $118 million for development, serving over 3 million users. That is around $39 per user.
    - **[Consensys (MetaMask)](https://www.crunchbase.com/organization/consensus-systems/company_financials)** raised $726 million for development, serving over 25 million users. That is around $29 per user.
    - **[Polkadot’s SubWallet](https://polkadot.dotreasury.com/#/users/1C42oGF3s8ztCsc22MA4LKd8BogMJNdVmCgtTXGfxqwjrSb/beneficiary/proposals)** received funding exceeding $1 million and is now serving over 250,000 users. That is only around $5 per user.


        | Funding \ Wallet | MetaMask (ETH) | SubWallet (DOT) | MantaWallet  |
        | --- | --- | --- | --- |
        | Total Funding | $726,000,000 | $1,286,717 | $310,000 |
        | Total users | 25,000,000 | 270,000 | 215,000 |
        | Cost per user | $29 | $5 | $1.44 |
3. **MantaWallet team is committed to and focused on building**
We have been highly focused and committed to building products and shipping new features. We consistently prioritize product delivery and gaining traction, ensuring that what we build contributes tangible value to the ecosystem before seeking any funding.
4. **MantaWallet team makes a comprehensive contribution to Polkadot ecosystem growth**
In addition to our proficiency in product development, we possess robust marketing and sales capabilities. We are capable of effectively bringing our products to market and expanding our user base, rather than building a product with very few users. We firmly believe that we have actively contributed to the growth of the ecosystem, making it more vibrant and robust.

# 4. Why should MantaWallet be supported?

---

1. **The wallet plays a crucial role in a blockchain ecosystem**
A blockchain wallet serves as a cornerstone for any thriving ecosystem, comparable to a browser in the realm of the internet. Without a functional blockchain wallet, users have no access to ecosystem features and applications, which hinders the ecosystem's potential for growth. Therefore, the wallet is an important infrastructure for the ecosystem that should receive support for its development.
Money inherently loses value, and the same holds for DOT, which experiences an annual inflation rate of over 7%. When left static, it progressively loses value. Similar to the economic development of a country, funds need to be circulated and invested wisely, particularly in building essential infrastructure.
2. **Wallet development is resource-intensive**
Contrary to common assumptions, our treasury allocation does not equate to substantial funding. A comparative analysis with leading wallets in other ecosystems reveals the substantial investments required for wallet development.
    - **[Solana's Phantom](https://www.crunchbase.com/organization/phantom-3171)** raised $118 million for development, serving over 3 million users. That is around $39 per user.
    - **[Consensys (MetaMask)](https://www.crunchbase.com/organization/consensus-systems/company_financials)** raised $726 million for development, serving over 25 million users. That is around $29 per user.
    - **[Polkadot’s SubWallet](https://polkadot.dotreasury.com/#/users/1C42oGF3s8ztCsc22MA4LKd8BogMJNdVmCgtTXGfxqwjrSb/beneficiary/proposals)** received funding exceeding $1 million and is now serving over 250,000 users. That is only around $5 per user.


        | Funding \ Wallet | MetaMask (ETH) | SubWallet (DOT) | MantaWallet  |
        | --- | --- | --- | --- |
        | Total Funding | $726,000,000 | $1,286,717 | $310,000 |
        | Total users | 25,000,000 | 270,000 | 215,000 |
        | Cost per user | $29 | $5 | $1.44 |
3. **MantaWallet team is committed to and focused on building**
We have been highly focused and committed to building products and shipping new features. We consistently prioritize product delivery and gaining traction, ensuring that what we build contributes tangible value to the ecosystem before seeking any funding.
4. **MantaWallet team makes a comprehensive contribution to Polkadot ecosystem growth**
In addition to our proficiency in product development, we possess robust marketing and sales capabilities. We are capable of effectively bringing our products to market and expanding our user base, rather than building a product with very few users. We firmly believe that we have actively contributed to the growth of the ecosystem, making it more vibrant and robust.

# 2. What is MantaWallet**?**

---

![Slide 16_9 - 18.jpg](https://i.postimg.cc/LXxH2fpX/Slide-16-9-18.jpg)

**MantaWallet is the leading comprehensive non-custodial wallet** for the Polkadot and Kusama ecosystems. With the browser extension installed, Manta wallet allows you to engage with Web3 apps on the Manta blockchain.

Manta Wallet has been released for more than half a year. It is the wallet with the **second largest number of users** in the Polkadot ecosystem (the first is the official Polkadot.js).

# 3. What has MantaWallet achieved?

---

![01.jpg](https://i.postimg.cc/CMC2BYBG/01.jpg)

The MantaWallet team started building in Feb 2023. Since then, we have been highly focused on building fast and efficiently. Below are our achievements by the numbers:

## Tractions:

- Total Chrome Store users **215K+** [https://chrome.google.com/webstore/detail/enabgbdfcbaehmbigakijjabdpdnimlg](https://chrome.google.com/webstore/detail/enabgbdfcbaehmbigakijjabdpdnimlg)
- Manta Wallet has developed a total of **28 versions**. [https://github.com/Manta-Network/manta-extension/releases](https://github.com/Manta-Network/manta-extension/releases)
- xxx zkAddresses activated on Manta Wallet
- xxx transactions related to zk on Manta Wallet.

## Key features:

- 🔐 Create wallet accounts with both public address and zkAddress with a single mnemonic.
- ✅ Import, and persistently store the mnemonics and the derived private key.
- ✅ View public assets and zkAssets in the wallet.
- ✅ Connect to DApps and sign human-readable transactions from trusted DApps.
- ✅ zkAssets public2Private, private2Private, private2Public
- ✅ Show your recent public / private transactions

![Slide 16_9 - 20.jpg](https://i.postimg.cc/x19NfGrG/Slide-16-9-20.jpg)

## Framework Design(Kumi):

There has three parts in Chrome Extension V3 version.

- Inject script (To web site)
- Service work
- Pop up

In order to better integrate the web3 ecosystem, a set of RPC communication protocol has been designed based on PostMessage.

![framework.jpg](https://i.postimg.cc/SRQfYB3d/framework.jpg)

### Service Work Part

In Service Work, we have many things to handle, such as:

- Message listening
- Business logic
- Data storage
- Scheduled Tasks
- etc…

This looks a bit familiar, like a backend framework. Yes, we are designing a backend framework. I think everyone should be familiar with Koa.js. I borrowed Koa's ideas and designed an RPC version of the framework.

Kumi.js:

![Slide 16_9 - 21.jpg](https://i.postimg.cc/nhfMd4cb/Slide-16-9-21.jpg)

At the organizational code level, use the classic Controller & Service & Model.

![Slide 16_9 - 17.jpg](https://i.postimg.cc/RFLBGtFd/Slide-16-9-17.jpg)

Especially important, the ServiceWork will be restarted within 5 minutes at most, so there is no session in memory, and all users' data is persistence in IndexedDB/Chrome Storage.

## Manta-SDK Design & Introduction:

Manta-SDK is implemented using TS/Rust and focuses primarily on zkAddress and zkAssets functionalities. It enables operations such as Public2Private for Assets, PrivatetoPublic for zkAssets, privateTransfer, and implements features like zkNFT.

The primary aim of Manta-SDK is to provide a set of functionalities including zkAddress, zkAssets, and asset transfer operations that any wallet can easily incorporate through simple configurations. By encapsulating complex logic and offering a user-friendly API, it aims to simplify integration for developers. Currently, it supports two environments: Node and Browser.

### Functionality Overview of Manta-SDK:

1. Feature List
    - Ledger Management: Includes downloading, parsing, assembling, etc., of the Ledger.
    - BaseWallet: The foundational instance for all wallets, responsible for handling common logic.
    - PrivateWallet: The base class for all wallets, managing common wallet functions.
    - MantaPayWallet: Inherits from PrivateWallet and implements functions related to MantaPay.
    - MantaSbtWallet: Inherits from PrivateWallet and implements functions related to MantaSBT.

Interface List: [https://github.com/Manta-Network/sdk/blob/signer_extension/manta-js/package/src/interfaces.ts](https://github.com/Manta-Network/sdk/blob/signer_extension/manta-js/package/src/interfaces.ts)

# 2. What is MantaWallet**?**

---

![Slide 16_9 - 18.jpg](https://i.postimg.cc/LXxH2fpX/Slide-16-9-18.jpg)

**MantaWallet is the leading comprehensive non-custodial wallet** for the Polkadot and Kusama ecosystems. With the browser extension installed, Manta wallet allows you to engage with Web3 apps on the Manta blockchain.

Manta Wallet has been released for more than half a year. It is the wallet with the **second largest number of users** in the Polkadot ecosystem (the first is the official Polkadot.js).

# 3. What has MantaWallet achieved?

---

![01.jpg](https://i.postimg.cc/CMC2BYBG/01.jpg)

The MantaWallet team started building in Feb 2023. Since then, we have been highly focused on building fast and efficiently. Below are our achievements by the numbers:

## Tractions:

- Total Chrome Store users **215K+** [https://chrome.google.com/webstore/detail/enabgbdfcbaehmbigakijjabdpdnimlg](https://chrome.google.com/webstore/detail/enabgbdfcbaehmbigakijjabdpdnimlg)
- Manta Wallet has developed a total of **28 versions**. [https://github.com/Manta-Network/manta-extension/releases](https://github.com/Manta-Network/manta-extension/releases)
- xxx zkAddresses activated on Manta Wallet
- xxx transactions related to zk on Manta Wallet.

## Key features:

- 🔐 Create wallet accounts with both public address and zkAddress with a single mnemonic.
- ✅ Import, and persistently store the mnemonics and the derived private key.
- ✅ View public assets and zkAssets in the wallet.
- ✅ Connect to DApps and sign human-readable transactions from trusted DApps.
- ✅ zkAssets public2Private, private2Private, private2Public
- ✅ Show your recent public / private transactions

![Slide 16_9 - 20.jpg](https://i.postimg.cc/x19NfGrG/Slide-16-9-20.jpg)

## Framework Design(Kumi):

There has three parts in Chrome Extension V3 version.

- Inject script (To web site)
- Service work
- Pop up

In order to better integrate the web3 ecosystem, a set of RPC communication protocol has been designed based on PostMessage.

![framework.jpg](https://i.postimg.cc/SRQfYB3d/framework.jpg)

### Service Work Part

In Service Work, we have many things to handle, such as:

- Message listening
- Business logic
- Data storage
- Scheduled Tasks
- etc…

This looks a bit familiar, like a backend framework. Yes, we are designing a backend framework. I think everyone should be familiar with Koa.js. I borrowed Koa's ideas and designed an RPC version of the framework.

Kumi.js:

![Slide 16_9 - 21.jpg](https://i.postimg.cc/nhfMd4cb/Slide-16-9-21.jpg)

At the organizational code level, use the classic Controller & Service & Model.

![Slide 16_9 - 17.jpg](https://i.postimg.cc/RFLBGtFd/Slide-16-9-17.jpg)

Especially important, the ServiceWork will be restarted within 5 minutes at most, so there is no session in memory, and all users' data is persistence in IndexedDB/Chrome Storage.

## Manta-SDK Design & Introduction:

Manta-SDK is implemented using TS/Rust and focuses primarily on zkAddress and zkAssets functionalities. It enables operations such as Public2Private for Assets, PrivatetoPublic for zkAssets, privateTransfer, and implements features like zkNFT.

The primary aim of Manta-SDK is to provide a set of functionalities including zkAddress, zkAssets, and asset transfer operations that any wallet can easily incorporate through simple configurations. By encapsulating complex logic and offering a user-friendly API, it aims to simplify integration for developers. Currently, it supports two environments: Node and Browser.

### Functionality Overview of Manta-SDK:

1. Feature List
    - Ledger Management: Includes downloading, parsing, assembling, etc., of the Ledger.
    - BaseWallet: The foundational instance for all wallets, responsible for handling common logic.
    - PrivateWallet: The base class for all wallets, managing common wallet functions.
    - MantaPayWallet: Inherits from PrivateWallet and implements functions related to MantaPay.
    - MantaSbtWallet: Inherits from PrivateWallet and implements functions related to MantaSBT.

    - Enhance wallet integration solutions to facilitate more wallets adopting Manta-SDK. This involves adding detailed tutorials and streamlining integration steps.
    - Introduce CLI support, enabling developers to operate SDK via CLI for easier debugging and development.

# 4. Why should MantaWallet be supported?

---

1. **The wallet plays a crucial role in a blockchain ecosystem**
A blockchain wallet serves as a cornerstone for any thriving ecosystem, comparable to a browser in the realm of the internet. Without a functional blockchain wallet, users have no access to ecosystem features and applications, which hinders the ecosystem's potential for growth. Therefore, the wallet is an important infrastructure for the ecosystem that should receive support for its development.
Money inherently loses value, and the same holds for DOT, which experiences an annual inflation rate of over 7%. When left static, it progressively loses value. Similar to the economic development of a country, funds need to be circulated and invested wisely, particularly in building essential infrastructure.
2. **Wallet development is resource-intensive**
Contrary to common assumptions, our treasury allocation does not equate to substantial funding. A comparative analysis with leading wallets in other ecosystems reveals the substantial investments required for wallet development.
    - **[Solana's Phantom](https://www.crunchbase.com/organization/phantom-3171)** raised $118 million for development, serving over 3 million users. That is around $39 per user.
    - **[Consensys (MetaMask)](https://www.crunchbase.com/organization/consensus-systems/company_financials)** raised $726 million for development, serving over 25 million users. That is around $29 per user.
    - **[Polkadot’s SubWallet](https://polkadot.dotreasury.com/#/users/1C42oGF3s8ztCsc22MA4LKd8BogMJNdVmCgtTXGfxqwjrSb/beneficiary/proposals)** received funding exceeding $1 million and is now serving over 250,000 users. That is only around $5 per user.


        | Funding \ Wallet | MetaMask (ETH) | SubWallet (DOT) | MantaWallet  |
        | --- | --- | --- | --- |
        | Total Funding | $726,000,000 | $1,286,717 | $310,000 |
        | Total users | 25,000,000 | 270,000 | 215,000 |
        | Cost per user | $29 | $5 | $1.44 |
3. **MantaWallet team is committed to and focused on building**
We have been highly focused and committed to building products and shipping new features. We consistently prioritize product delivery and gaining traction, ensuring that what we build contributes tangible value to the ecosystem before seeking any funding.
4. **MantaWallet team makes a comprehensive contribution to Polkadot ecosystem growth**
In addition to our proficiency in product development, we possess robust marketing and sales capabilities. We are capable of effectively bringing our products to market and expanding our user base, rather than building a product with very few users. We firmly believe that we have actively contributed to the growth of the ecosystem, making it more vibrant and robust.

2. Future Plans for Manta-SDK:
    - Optimize logic to reduce ledger synchronization time. Currently, ledger data is extensive, requiring time for synchronization. Future optimization plans aim to save time for users and developers.
    - Enhance wallet integration solutions to facilitate more wallets adopting Manta-SDK. This involves adding detailed tutorials and streamlining integration steps.
    - Introduce CLI support, enabling developers to operate SDK via CLI for easier debugging and development.

# 4. Why should MantaWallet be supported?

---

1. **The wallet plays a crucial role in a blockchain ecosystem**
A blockchain wallet serves as a cornerstone for any thriving ecosystem, comparable to a browser in the realm of the internet. Without a functional blockchain wallet, users have no access to ecosystem features and applications, which hinders the ecosystem's potential for growth. Therefore, the wallet is an important infrastructure for the ecosystem that should receive support for its development.
Money inherently loses value, and the same holds for DOT, which experiences an annual inflation rate of over 7%. When left static, it progressively loses value. Similar to the economic development of a country, funds need to be circulated and invested wisely, particularly in building essential infrastructure.
2. **Wallet development is resource-intensive**
Contrary to common assumptions, our treasury allocation does not equate to substantial funding. A comparative analysis with leading wallets in other ecosystems reveals the substantial investments required for wallet development.
    - **[Solana's Phantom](https://www.crunchbase.com/organization/phantom-3171)** raised $118 million for development, serving over 3 million users. That is around $39 per user.
    - **[Consensys (MetaMask)](https://www.crunchbase.com/organization/consensus-systems/company_financials)** raised $726 million for development, serving over 25 million users. That is around $29 per user.
    - **[Polkadot’s SubWallet](https://polkadot.dotreasury.com/#/users/1C42oGF3s8ztCsc22MA4LKd8BogMJNdVmCgtTXGfxqwjrSb/beneficiary/proposals)** received funding exceeding $1 million and is now serving over 250,000 users. That is only around $5 per user.


        | Funding \ Wallet | MetaMask (ETH) | SubWallet (DOT) | MantaWallet  |
        | --- | --- | --- | --- |
        | Total Funding | $726,000,000 | $1,286,717 | $310,000 |
        | Total users | 25,000,000 | 270,000 | 215,000 |
        | Cost per user | $29 | $5 | $1.44 |
3. **MantaWallet team is committed to and focused on building**
We have been highly focused and committed to building products and shipping new features. We consistently prioritize product delivery and gaining traction, ensuring that what we build contributes tangible value to the ecosystem before seeking any funding.
4. **MantaWallet team makes a comprehensive contribution to Polkadot ecosystem growth**
In addition to our proficiency in product development, we possess robust marketing and sales capabilities. We are capable of effectively bringing our products to market and expanding our user base, rather than building a product with very few users. We firmly believe that we have actively contributed to the growth of the ecosystem, making it more vibrant and robust.
