Wallet At the beginning, we will rely on existing non-custodial wallets available on the market. This allows users to continue using wallets they’re familiar with.\ However, for this project, the wallet must also manage the **Private state** of smart contracts — a feature not supported by current wallets nor exposed via extension interfaces.\ To address this in the early stages, we’ll use **user local storage encrypted with the wallet key**.\ In future releases, we plan to develop a new wallet capable of securely storing both **Private state data** and **user keys**. #### 2. dApp The dApp serves as an extended interface for users, displaying available data and relying on the Wallet for encryption/decryption and transaction signing.\ It will be built using **existing Web3 frameworks**, adapted to support **new generation smart contracts**. #### 3. Internal Ledger As with most Web3-based products, an internal **decentralized ledger** will be used to process transactions and form blocks sequentially.\ The key distinction of our ledger is its **support for new generation smart contracts**. #### 4. R-Bridge A suite of smart contracts operating across both the **Internal and External ledgers**, designed to bridge crypto assets between them.\ The external part of the bridge tracks internal transactions via **state-proofs** (similar to L2 rollup validators posting data to L1).\ This allows users to present a state-proof and **claim corresponding crypto assets on the External chain**, avoiding the need to directly interact with the Internal chain — a critical **safety feature**. *** The interaction between these components is illustrated in the diagram below
