Architecture Overview

YLD operates on a multi-layered architecture designed for scalable DeFi strategy execution across Solana protocols. The system consists of seven primary service components working in coordination:

Core Components

Front-End + Privy Auth – User interface with embedded wallet/auth layer that initiates deposits, withdrawals, and strategy commands.

Smart Vaults – Non-custodial programs that hold user assets and expose controlled hooks for agents to draw or return funds.

YLD Agents – Autonomous agents that translate strategy logic into executable intents using vault liquidity.

Execution Engine – Off-chain service that batches intents, performs pre-trade checks, and assembles atomic transaction bundles.

Protocol Services (MCP) – Middleware that maps high-level intents to onchain instructions and risk guards.

Jito Bundler – Provides MEV protection and enables atomic transaction bundling for strategy deployment

Solana DeFi Protocols (Kamino, Drift, etc.) – Target venues where the bundled transactions execute to generate yield or manage positions.

By unbundling custody from execution and threading each layer:

• Smart Vaults for self-custody

• Agents for autonomous logic

• Execution Engine + MCP for programmatic orchestration

• Jito for secure settlement

YLD turns static deposits into programmable capital. Users remain the ultimate key-holders of their assets while the system composes, routes, and settles complex yield strategies across Solana in a single, verifiable flow. In short, you keep the keys; the architecture does the work.
