Blend’s architecture centers on the “Pocket Hedge Fund” model: every user’s capital is isolated in their own Gnosis Safe, orchestrated by a modular and constraint-aware Yield Coordination Engine. This design ensures self-custody by building on top of battle-tested DeFi primitives like Gnosis Safe and Morpho, rather than reinventing core components.

Core Components

  • API Server: Manages user sessions, positions, and Safe orchestration. Provides REST API for external integrations.
  • Worker: Executes background processes like rebalancing and health checks.
  • Indexer: Monitors on-chain events for real-time state synchronization.
  • Allocator: The core of the Yield Coordination Engine; calculates optimal, risk-adjusted allocations across integrated DeFi primitives.
  • Scheduler: Triggers periodic jobs based on time and market conditions.
  • Reporter: Provides system metrics and user analytics.
