🔑 ✨ Rubeus ✨ 🔐

This is an Ink! smartcontract implementing credentials storage logic.
With this contract you can create/update/delete your encrypted credentials in a blockchain database. It works with client-side DApp.

Design and features

• Contract set-up with owner, set by constructor's argument, or set caller by default.
• After initialization of the contract users can save credentials. All payload need to be encrypted before saving in storage, you can make it from the dapp.
• CRUD operations with credentials.
• Contract own management and transfer ownership.

How to

Install Prerequisites

Please follow installation instructions provided here.

Clone this repo

git clone https://github.com/bsn-si/rubeus-smartcontract

Compile + Run Tests

cd rubeus-smartcontract
cargo test

Also you can run an example from the /example folder, that is written with polkadot.js and works with client-side encryption. To run example please follow these steps:

cd example/
npm install 
npm run start

Build Contract + metadata

cargo contract build

Resolve common errors

You need wasm target and dylint set. To install specified toolchain & targets please run:

rustup target add wasm32-unknown-unknown
cargo install cargo-dylint

In case you get a compilation error during the wasm optimization step, make sure you have binaryen installed.

Deploy on testnet

First setup and start substrate-contracts-node, go to Polkadot Portal UI for setting up a test contract.

After creating an instance of the contract on the blockchain you can use a core owner from test accounts list like Alice. Next you need to send funds to the contract and then you can call contract's methods from Polkadot Portal UI.

Example usage

• Instantiate new contract with Alice owner.
• From Polkadot Portal UI call addCredential method, enter any payload with a unique ID - you can generate it or choose any for test from the list
• Call method with Execute action on Polkadot Portal UI.
• You can load all your credentials with method getCredentials
