# Technical details Stazys delivers secure, autonomous strategies with one-click deposits and withdrawals. Here's how it works. ### Position Graphs: On-Chain Route Encoding Strategies are encoded into **position graphs,** on-chain representations containing only token positions and protocol interactions. Routes are **encoded in the graph**, ensuring assets cannot escape their predefined paths. Custody remains with the on-chain program at all times, and the engine executes the graph exactly as designed. ### Optimistic Execution with Proof Verification Strategy logic is assured **optimistically by our engine**. The engine executes each step and posts a **transaction proof** for every operation, including: * The path taken through the strategy * Token mints and amounts moved * Protocol interactions and parameters * Transaction hash and on-chain data **Users can verify** that their strategies were correctly executed by checking these proofs. This transparency ensures strategy integrity while maintaining autonomous execution. ### One-Click Deposits and Withdrawals Enabling seamless deposits and withdrawals requires permissionless AUM (assets under management) calculation without price manipulation risk. Stazys uses multiple security layers: * **Authorized Token List** — Only tokens with sufficient liquidity, market depth, price stability, and audited provenance * **Pyth TWAP Oracles** — Time-weighted average prices (30-second window) from multiple sources, verified on-chain with staleness protection * **Redemption Fee Protection** — 0.1% fee plus rounding-down mechanisms to prevent micro-exploits Together, these mechanisms secure the ecosystem while enabling accurate, 1-click user interactions. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
