Architecture Overview
Client & Wallet Layer
The client and wallet layer is responsible for wallet creation, import, and connection flows. It supports both locally managed wallets and externally delegated signing through compatible Stellar wallets.
This layer handles transaction construction and user confirmation prior to signing. Private keys remain under user control at all times and are never transmitted to Lumexo infrastructure.
Application Logic
The application coordination layer manages interaction flows for asset management, trading, liquidity participation, lending, and payments. It standardizes how decentralized financial operations are prepared and executed, ensuring consistent behavior across supported use cases.
Stellar Network Layer
The Stellar network functions as the execution and settlement layer for all transactions. Lumexo leverages native Stellar primitives, including decentralized exchange functionality, automated market makers, and Soroban-based smart contracts.
Data & Indexing
Data and indexing services aggregate and cache on-chain information required for portfolio views, market data, liquidity metrics, and historical activity. These services do not participate in transaction execution or custody.
The Stellar network remains the authoritative source of truth for all balances and transaction state.
External dApp Interaction
Lumexo supports interoperability with external decentralized applications by acting as a signing surface rather than an execution intermediary. In this model, third-party applications generate transaction requests, which are presented to the user within Lumexo for review and approval prior to signing.
Architectural Scope
This section provides a high-level overview of the Lumexo system architecture. Detailed implementation specifics, transaction flows, signing mechanisms, and integration details are documented separately in the technical documentation.
