Blockchain Integration Layer
The Blockchain Integration Layer is responsible for connecting Sallet to different blockchain networks, enabling it to support multiple chains like Ethereum, Solana, Bitcoin, Polygon, Base, and others. This layer handles communication between Sallet and the underlying blockchains, facilitating the reading and writing of data across different ecosystems.
Blockchain SDKs: Sallet uses blockchain-specific Software Development Kits (SDKs) to connect to each blockchain it supports. These SDKs are tailored to the unique protocols of each chain and enable Sallet to interact with smart contracts, fetch account balances, and broadcast transactions.
Cross-Chain API: The integration layer uses a Cross-Chain API to standardize the process of interacting with different blockchains. This API abstracts the underlying complexities of each blockchain, enabling Sallet to execute cross-chain actions (such as asset transfers, token swaps, and DeFi interactions) with a consistent interface.
Blockchain Adapters: For each supported blockchain, Sallet deploys a blockchain adapter that acts as a middleware between the wallet and the chain. This adapter translates user actions into blockchain-specific calls and manages the response back to the wallet interface. For example, an Ethereum adapter might handle ERC-20 token transfers, while a Solana adapter manages SPL token interactions.
