PlutoWallet

Multi-platform mobile wallet for substrate-based chains. Focuses on the best UX. First C# mobile wallet in Polkadot ecosystem.

Supported platforms:

• Android & WearOS
• iOS & ipadOS
• MacCatalyst
• Windows

The wallet supports these functionalities:

• generating Mnemonics & creating a privateKey
• showing and sharing your public key and ss58 key
• connecting to any substrate based blockchain/parachain
• fetching asset balance from Balances, Assets and Tokens pallet
• transfer of assets from Balances and Assets pallet
• fee calculation
• shows transaction status
• NFTs (powered by Uniquery.Net)
• contracts (Currently just Counter Sample)
• connect to any dApp thanks to Plutonication
• See detail of your account on Calamar.app
• See your Liquidity positions on HydraDX omnipool
• See your recent Referenda votes and view all details on Subsquare.io
• Securely sign any extrinsics with Polkadot Vault qr signing
• View your AZERO.ID primary name and details
• Light and Dark mode

3rd party integrations:

• Calamar explorer
• Kodadot unlockables
• HydraDX
• Awesome Ajuna Avatars
• AZERO.ID
• SubSquare
• Polkadot Vault

Differentiating factors

1) Multinetwork optimisation

The UI/UX is optimised to support multichain out of the box. Instead of having one chain selected at a time, you can have chain groups. This makes the UI more approachable and simple.

2) Adjustable layouts (PlutoLayouts)

• Well prepared video presentation: https://youtu.be/ojU8-w6u5Oo
• Subsquare discussion: https://polkadot.subsquare.io/posts/155

Extremely important tool for onboarding new users. Not only can you optimise UI layouts to your needs, you can also export them to other users. This can be especially handy for dApp projects:

• In a typical use-case, dApp developers would have to teach new users how to use their wallets. It is usually a big hassle, the user has to find the chain they are looking for and they would still see many confusing crypto functionalities that they would not care about.
• With PlutoLayouts, dApp developers can export the ideal layout (UX optimised for their specific app) and share them to the new users so that they have got the ideal UX out of the box. They will see only features they would actually care about.
• It is highly customisable. When the users decide they want to do more in the ecosystem, they can easily add more functionalities to the wallet. They can learn to use Polkadot on their own pace.

3) Plutonication

Plutonication allows users to connect PlutoWallet to other dApps seamlessly on any platforms, accross multiple codebases, while preserving security.

DApp just generates a QR code and once it is scanned in the wallet, they will pair and the wallet will be able to receive transaction requests from the dApp. To learn more, visit https://github.com/cisar2218/Plutonication.

• It works the similarly to WalletConnect protocol.

4) Multiplatform development

This project is developed using .net MAUI framework, which allows simple development of native mobile apps on many different platforms from a single codebase. This is crucial for quick (and easier) development while preserving the quality.

5) Market leading NFT support

The largest NFT support in the whole Polkadot ecosystem, thanks to Uniquery.Net.

Supported Networks/NftStandards:

• Rmrk
• RmrkV2
• Basilisk
• Glmr
• Movr
• Unique
• Quartz
• Opal
• Acala (OnFinality BETA)
• Astar (OnFinality BETA)
• Shiden (OnFinality BETA)
• Statemine/Statemint/Rockmine Nfts pallet
• Statemine/Statemint/Rockmine Uniques pallet
• tzero.id (currently just Aleph Zero Testnet)
• azero.id (soon)
• more to come...

Plutonication

Allows the wallet to communicate with any dApps and sign their respective transaction requests without the risk of compromising the private key.

Security

1) Private key generation

• Private key is generated with RandomNumberGenerator which creates cryptographically strong random values. This entropy is then passed to Mnemonic.MnemonicFromEntropy(<entropyBytes>, BIP39Wordlist.English); to generate the mnemonics.

2) Secure storage

• Private key / Mnemonics are saved in the Secure storage according to these docs: https://learn.microsoft.com/en-us/dotnet/maui/platform-integration/storage/secure-storage.

Terminology

• dApp = any application that uses crypto functionalities. In order to use dApps, it needs to communicate with the crypto wallet somehow, or it needs to know your private key (very insecure).
• Substrate key = ss58 encoded key with "42" prefix.
• Chain-specific key = ss58 encoded key with a custom prefix.
• Chain = either standalone blockchain, relay chain, or parachain. (and/or combination of them)
• Extrinsic = A transaction (more info: https://wiki.polkadot.network/docs/learn-extrinsics)
• PlutoLayout = a simple way to save and export custom layouts.

Project folder structure
