VEX Desktop 0.4.2. Your keys. Your machine. Your agent.

• Open VEX. System Check measures your disk and memory first, and if there is not room for the model and the database, it tells you how much space it needs.
• On first run VEX creates its local database and downloads the embedding model once, about 333 MB, checked against a pinned fingerprint before it is used.
• Connect an AI model: choose Vex Inference and sign in with your wallets, then deposit VEX from the app; or paste your own OpenRouter API key and pay OpenRouter directly for what the models use.
• Create your EVM and Solana wallets, or restore them from a backup. Set a master password. VEX writes a backup archive automatically.
• Start a session: Agent or Mission, Restricted or Full Autonomous. The choice is fixed for that session.

What ships in the app: a PostgreSQL 18.6 database with pgvector 0.8.7 and a llama.cpp embeddings server running EmbeddingGemma 300M. No Docker. It runs on macOS on Apple Silicon or Intel, Windows x64 or Windows on Arm, and Linux x64. The first launch needs the internet once, for the model download. The database and the embeddings server listen only on 127.0.0.1, start when you open VEX and stop when you quit. The app must stay open: Desktop works only while it runs. Coming from a version that ran on Docker? Move my data copies your sessions, missions, memory and settings across in one click and checks the copy before VEX uses it.

• A backup archive is written automatically. You can export your wallets and restore them.
• No hardware wallet support.
• The code is source-available under the VEX Source-Available License v1.0, published so you can read and audit it.

• Approvals expire after 1 hour.
• Slippage is 1% by default, with a hard cap of 10%.
• Even in Full Autonomous, a price-and-safety check no older than 15 minutes from the same venue is required, and every send goes through prepare, then confirm.
• Full Autonomous Agent sessions have no mission contract. The wallets you attach are the only limit.

VEX fees depend on the operation. See the fee table for current rates and operations with no VEX fee. Model costs are separate.
