Products

Four products. Each one shows its status.

  • VEX Desktop

    Livev0.4.0

    A self-custodial AI agent that runs on your own computer. Your keys never leave it, and it asks before it moves money unless you choose otherwise.

    macOS · Windows · Linux

  • VEX in your browser and in Telegram. It runs on VEX's servers, so your strategies keep running while you are offline.

    Web app · Telegram

  • VEX Arena

    In development

    A public experiment: AI models each get a funded wallet, the same tools and seven days to trade on their own, with every step published. No round has run yet.

    Coming soon

  • VEX Mobile

    Planned

    A native phone app to talk to your agent, approve its actions and watch what it does. Same agent, memory and limits as VEX Cloud. Not built yet.

The agentChapters

The agent

Chapter 2. The model proposes. The runtime enforces. You decide.

A language model is good at reading markets and bad at being trusted with money. So in VEX the model only suggests actions. Code the model cannot change checks each one, and by default anything that moves money waits for you.

One user, one agent

  • In VEX Cloud each account has one agent. It keeps your recent conversation (the last 40 messages plus a running summary), your memory and your limits. You reach the same agent in the web app and in Telegram.

    BetaTelegramIn development
  • VEX Mobile, a native app, will talk to that same agent, with the same memory and limits.

    Planned
  • In VEX Desktop the agent lives in the app on your computer, with its memory in a local database. You work with it in sessions.

    Live

What the model can and cannot do

The model can

  • Read markets and your portfolio.
  • Propose a trade: which asset and how much.
  • Draft a mission with you in chat (Desktop) or a strategy (Cloud).

The model cannot

  • Choose calldata, contracts, slippage or minimum output. Those come from your settings and VEX policy.

    CloudBeta

  • Set a fee. Fee rates are fixed in code.

    DesktopLive

  • Write the approval card. It shows the exact signed arguments, the VEX fee and a safety verdict from VEX's own check, never model text.

    DesktopLive

  • Start a mission. Only your click starts a run.

    DesktopLive

  • Hold a key, or unlock anything through memory.

    both

Missions

Desktop

Live

A mission is a contract you fill in through chat: goal, capital, wallets, chains, protocols, risk profile, success criteria and stop conditions. Your acceptance is tied to those exact terms, and only your click starts the run. Desktop runs missions only while the app is open. Close it, or let the computer sleep, and the mission stops making progress.

Cloud

PlannedstrategiesBeta

In VEX Cloud a mission will be a plain-language instruction on a schedule, with its own budget, and its results will land in your chat. Missions are not built yet. Today Cloud runs strategies instead: pick a template, backtest it, run it on paper, then live, and VEX's workers check it while you are away.

How many missions you can run at once depends on your staking tier (Proposed, see (07)).

1 hour Approvals expire

1% Slippage by default

10% Slippage hard cap

Desktop approvals show exactly what will be signed and expire after 1 hour. 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. Slippage is 1% by default, with a hard cap of 10%.

The pause switch

Desktop

Live

Every mission carries its own stop conditions, and nothing runs while the app is closed. Agent Scan keeps a permanent history of everything the agent did.

Cloud

Beta

Pause all, in the header, stops every new action from your agent at once. VEX also has global, venue and deployment pauses. Every pause is checked before an order is created and again right before it is signed. Pausing closes open futures positions with reduce-only orders. The global pause starts switched on.

Custody and executionChapters

Custody and execution

Chapter 3. Who holds the keys, and who can sign.

VEX Desktop keeps your keys on your computer. VEX Cloud trades from a wallet you own and lets VEX sign inside a policy you can revoke. Here is exactly what each one means.

VEX Desktop

Live

Your keys are created and encrypted on your own computer and never leave it. By default, every action that moves money waits for your approval, and the approval shows exactly what will be signed. If you choose Full Autonomous, the agent acts without asking, limited only by the wallets you attach.

  • EVM and Solana keys, generated and stored in a local encrypted vault (AES-256-GCM, scrypt N=2^17, r=8, p=1).
  • Your master password is held only in memory. VEX asks for it again after every restart.
  • A backup archive is written automatically. You can export and restore.
  • VEX servers never hold your keys.
  • No hardware wallet support.

VEX Cloud

Beta

VEX Cloud trades from a wallet you own. When you turn trading on, you give VEX's execution service a limited right to sign for that wallet: only listed chains, apps and amounts, and you can take that right back at any time. Inside your limits it can act without asking you each time. The AI never holds a key. It can only propose. Every order is checked against your limits and pauses before it is signed, and again just before it goes out.

  • Your wallet is a Privy embedded wallet: one EVM address and one Solana address. VEX stores only its id, address and policy id, never a private key.
  • It is created when you choose to enable trading, not when you sign in.
  • VEX's signer works under a deny-by-default policy: listed chains, protocols, routers and bridges only, with caps on transfers.
  • Revoke server signing removes that signer at once.
  • The key that authorizes VEX's signer lives only in the execution service. The web app and the AI model never hold it.
  • Exchange accounts use your own trade-only keys (Binance mainnet keys must have withdrawals off and be IP-restricted), sealed so only the execution service can open them.
  • Hyperliquid: VEX creates an agent key that can trade but cannot withdraw. Lighter: VEX creates an API key that can request withdrawals, only to your own address, and signs them only when you ask.

Three checks, made twice.Beta

Every Cloud order is checked when it is created and again right before it is signed or sent. On-chain trades are simulated first.

The AI never holds a key. It can only propose.

  3. VEX policy: which chains, apps and amounts are allowed.

by defaultwaits for you

You decide

A transfer to a new address always waits for you.

After every fill VEX reconciles the result. An unknown or mismatched outcome pauses that strategy until a person looks at it, and nothing is sent twice. A transfer to a new address always waits for you.

Desktop: a fresh price-and-safety check from the same venue (15 minutes at most) before any trade, prepare then confirm for every send, slippage capped at 10%. Live

Mainnet is offBeta

VEX Cloud's execution service refuses mainnet unless someone switches it on on purpose. Today Cloud trades only on test networks.

Desktop's code is published as source-available, so anyone can check what it does with keys. VEX Cloud's code is private.

Memory and privacyChapters

Memory and privacy

Chapter 4. It remembers how you work. It never decides what it may do.

Memory is context, not permission. Here is what each product stores, where it lives, what you control, and what it does not do.

VEX DesktopLive

Where it lives

Memory, chat history, the database, wallet files and keys are stored only on your computer, in a local Postgres database with pgvector and a local EmbeddingGemma model.

How lessons are kept

The agent can only propose a lesson. Secrets and live state are refused. A judge decides what is kept. Nothing is deleted: lessons that fade are benched. Trade lessons are not re-scored against results.

What memory never does

Memory is advice. Sizing, approval and signing never read it.

What leaves your computer

  • Model calls through OpenRouter with your key, so your conversation goes to your model provider.
  • Requests to chains, venues and market-data services.
  • The $VEX price ticker.
  • A version check.
  • Setup downloads.
  • Crash reports, if you opt in.
  • An activity report to agentscan.projectvex.ai (Agent Scan), on by default.
  • pools.fun launch attestation, on by default.

VEX CloudBeta

Your agent remembers what you tell it: your preferences, facts you state, summaries of long chats and the documents you add. It learns only from your own messages, never from tool results, and it never stores keys, passwords, contact details or live balances. Memory is context, not permission: nothing in it can unlock an action. You can review, export or delete everything, or turn memory off. Chats and memories are stored as plain text in VEX's database and are kept until you delete them. Deleting a single chat or fact hides it but does not erase it.

What it remembers

  • Profile

    Example
    Name, form of address, language, response style, detail level, time zone
    Where it comes from
    What you say or set
  • Facts, up to 280 characters each

    Example
    "Trades only on Base", "Avoids memecoins"
    Where it comes from
    Your own messages
  • Chat summaries

    Example
    A rolling summary of a long chat
    Where it comes from
    Your chat
  • Your documents

    Example
    Files and pages you add: up to 10 MB each, 200 documents, 20 watched sources
    Where it comes from
    You add them

How memories are made

A background job reads only your own messages, never tool results or the agent's replies. What you state clearly is saved as confirmed. What it infers is saved as a suggestion that expires: after 14 days for profile values, 30 days for facts. A new fact supersedes the old one instead of overwriting it.

What it infers is saved as a suggestion that expires:

14 days for profile values

30 days for facts

Never stored

  • Private keys, seed phrases, passwords and one-time codes.
  • Email addresses and phone numbers.
  • Live balances, prices and positions.

Prompt rules and a hard filter both enforce this.

How memory is used

Each message gets your confirmed profile and at most 8 confirmed facts, 2,000 characters in total. The tool router, VEX policy and the execution service never read memory, so no memory can unlock an action. Telegram group chats read no personal memory.

Each message gets your confirmed profile and at most

8 confirmed facts

2,000 characters in total

Your controls

  • Review suggestions, each linked to the message it came from.
  • Delete all memory at once. This erases the memory text.
  • Turn memory off. Messages you send while it is off are never read for memory.
  • Export everything as JSON.

Background memory work is charged to your daily AI budget.

Where your data goes

The AI model that answers you (the platform model or your own provider), the tool router for platform runs, the embedding provider when it is switched on, Tavily (web search), Telegram, Resend (email), Privy (sign-in and wallets), Pinata (launch images), Goldsky, Blockscout and Helius (wallet addresses), and DexScreener through VEX's gateway.

$VEXLive

$VEX lives on Robinhood Chain. You never need it to use VEX Desktop. VEX charges 0.25% on agent trades, and the team's policy is that 85% of that fee buys back and burns VEX and 15% funds Ecosystem Growth.

0.25% per agent trade. 85% buys back and burns VEX. 15% funds Ecosystem Growth.

VEX charges a 0.25% platform fee on agent trades. The team's policy is that 85% of that fee buys back and burns VEX, and 15% funds Ecosystem Growth. Fees go to a public treasury address, and every buyback is on-chain and listed in the burn ledger below.

Live as a team policy. It is not enforced in code: in code, 100% of each fee goes to the treasury, and the team carries out buybacks from the treasury. An automated buyback on a schedule is Planned.

Burn ledger

Every VEX burned or sent to the dead address, from the chain.

Two different things get called a burn. Calling burn() destroys VEX and lowers total supply. Sending VEX to the dead address 0x000000000000000000000000000000000000dEaD puts it where nobody is known to hold a key, but total supply stays the same. This ledger shows both, separately, read from Robinhood Chain.

"Lowers total supply" is Yes only for burn(). The dead address column counts every transfer to 0x...dEaD, whoever sent it. Labels come from public sources.

The Virtuals taxLive

Separate from the VEX fee, Virtuals charges a 1% tax on buys and sells of VEX in the V2 pool. The tax is sold for USDG: 70% goes to the VEX treasury and 30% to Virtuals. Virtuals sets this tax. VEX cannot change it.

The treasury's share of this tax is one of the two sources planned to pay for CLOUD compute (see (06)).

How it worksPlanned

Stake 1 CLOUD and your agent can spend $1 of AI usage inside VEX each day. The allowance resets at 00:00 UTC and does not roll over. You mint CLOUD by locking staked VEX, and you get that VEX back when you burn the CLOUD.

  1. Stake VEX. You stake VEX and hold staked VEX. Unstaking VEX takes 7 days.
  2. Mint CLOUD. You lock staked VEX at the current Mint Rate to mint CLOUD. The Mint Rate is how much staked VEX one CLOUD needs. It rises as CLOUD supply gets close to the Target Supply.
  3. Stake CLOUD. Each staked CLOUD gives you $1 of AI compute inside VEX per day. The allowance resets at 00:00 UTC. Unused allowance does not roll over. Unstaking CLOUD takes 1 day.
  4. Hold, send or sell. CLOUD is a transferable token. Only staked CLOUD gives the allowance.
  5. Exit. Burning CLOUD unlocks the same amount of staked VEX that minted it. Your VEX was locked, never spent or burned.
  6. Supply. The Target Supply starts at 1,000 CLOUD. The team raises it in steps, by its own decision, and announces every change. CLOUD can never exceed 50,000.

Who pays for the computeProposed

The compute behind CLOUD is paid from VEX protocol income: the treasury's share of the 1% VEX trading tax, plus agent trading fees through the 15% Ecosystem Growth share. At most, VEX owes $1 a day for every CLOUD in existence: $1,000 a day at 1,000 CLOUD, $50,000 a day at the 50,000 cap.

Protocol income rises and falls with trading. What happens if it does not cover the compute owed is not decided yet.

Rules that stay from today's beta build

In VEX Cloud, minting CLOUD always waits for your approval and is never offered from Telegram.

Where the design comes from: Venice DIEM

CLOUD follows a model that already runs: Venice's DIEM. We compare the mechanics only, not prices.

What the code does today

  • A CLOUD minter exists only on Robinhood Chain testnet. It was built for an earlier one-way design and does not do staking, the Mint Rate, the Target Supply or burn-to-unlock. It will be replaced. On testnet
  • VEX Cloud's beta build raises a holder's daily AI budget by the token balance held. That rule will switch to staked CLOUD. In development

StakingChapters

StakingPlanned

Chapter 7. Stake VEX for lower fees and higher limits. Nothing is paid out.

Staking is for using VEX, not for income. Staked VEX lowers your platform fee, lets you run more missions at once and opens creator features. No staking reward is paid.

PlannedNo staking contract exists yet.

"Missions at once" counts VEX Cloud missions, which are planned. "Fee you pay" is the arithmetic of the discount.

Worked example

Ben stakes 500,000 VEX and reaches Silver. On a $1,000 swap he pays a $1.875 fee instead of $2.50.

Copy trading and vaultsChapters

Copy trading and vaultsPlanned

Chapter 8. Follow a strategy. Your money stays in your own wallet.

Creators publish strategies with declared limits. Followers run the same strategy in their own wallets, at their own size, under their own limits. In phase 1 VEX never pools follower money. Vaults come in phase 2, on Hyperliquid, where deposits stay.

PlannedNothing here is built. The Copy button on VEX Cloud's paper leaderboard makes a new strategy draft for you. It is not copy trading.

Roles 2

Creator. Builds a strategy from reviewed templates, declares its limits, publishes it
Planned
  1. Creator → Follower

    Creators publish

    followers copy in their own wallets

Follower. Follows a strategy that runs in their own wallet; sets an amount, a stop level and a maximum daily loss
Planned

Solid: works today. Dotted: designed, not built.

    What they need
    Funds in their own wallet and their own limits

Phase 1: copy trading

PlannedProposed

  • The creator publishes a strategy with declared limits: markets, maximum leverage, maximum drawdown and maximum position size.
  • A follower clicks Follow and sets an amount, a stop level and a maximum daily loss.
  • VEX runs the same strategy in the follower's own wallet. Every order passes the same checks as any VEX order.
  • Followers see results and declared limits, not the rules.
  • A follower can stop at any time and chooses whether open positions close or stay open.

Fees

Proposed

  • Creator fee: 10% of the follower's net profit above that follower's high-water mark, settled monthly in USDG. Nothing is charged on losses or while a follower is below their previous high.
  • VEX fee: the usual 0.25% on executed volume, discounted by staking tier.

Openwhich venues copy trading uses, how the VEX fee applies on exchange accounts (which pay no VEX fee today), and how the monthly creator fee is collected from follower wallets (Q12)

Worked example (high-water mark)

Cara follows a strategy. Month 1 her copy is up $100: the creator gets $10. Month 2 she is down $40: no fee. Month 3 she gains $60 and ends $20 above her previous high: the creator gets $2.

Risk controls

Proposed

  • Declared limits are enforced by VEX's policy engine, not by trust: an order outside them is refused before signing.
  • If a strategy breaks its declared drawdown, it pauses for every follower at once.
  • Each follower's own limits apply on top.
  • The global pause stops all copy trading.

Phase 2: vaults

PlannedProposed

  • A creator's agent runs a native Hyperliquid vault. Followers deposit directly on Hyperliquid, so their funds never pass through VEX.
  • VEX builds on Hyperliquid's newer HyperEVM vaults, so vault fees can follow the copy-trading rules above.
  • No pooled funds held by VEX and no vaults on VEX's own contracts before an audit and a legal review.

Hyperliquid, as of 8 October 2026: legacy vaults pay the leader a 10% profit share and require the leader to keep at least 5%. Depositors have a 1-day lock-up. Newer HyperEVM vaults can be tokenized with custom accounting. Legacy vaults do not support HIP-3 or spot.

Hyperliquid is connected in VEX Cloud (checked on testnet). It was removed from Desktop in v0.2.0.

Releases

VEX Desktop ships often.

  1. 020 v0.4.0

    The desk, on paper.

    A new look for the desktop app: paper by day, Night Ledger at night, an open-book layout, an eagle that shows the agent's state and the REAL FUNDS frame on every approval.

  2. 019 v0.3.1

    Faster turns. Faster clicks.

    Faster agent turns and desk actions, more responsive wallet operations, saved mission reasoning, encrypted wallet recovery and lower Lighter perpetual fees.

  3. 018 v0.3.0

    Kairos: the first build.

    The first Kairos build ships for Windows and Linux; macOS and the full release notes follow in 0.3.1, on the same code.

  4. 017 v0.2.14

    Unstuck.

    Stale Lighter reservations recover from verified evidence, orders use live account limits, and a chart click sets your limit price.

FAQ

Questions people ask.

Do I need $VEX to use VEX?

No, not for VEX Desktop: it never asks you to hold $VEX. VEX Cloud gives every guest 0.01 USD of AI a day and every signed-in member 0.05 USD, and you can add your own model key. Holders of the credit token get 1 USD a day per whole token held. CLOUD is the token held for inference credits on VEX Cloud; its minter is on Robinhood testnet only and mainnet is not deployed yet (audit pending).

What does the AI cost me?

In Desktop you bring your own OpenRouter key and pay OpenRouter directly. In VEX Cloud each run reserves its worst-case cost from your daily budget, then settles at the provider's list price. Runs on your own model key are not charged to that budget.

Who holds my keys?

In Desktop, you do: keys are created and encrypted on your computer and never leave it, and the code is published as source-available so anyone can check. In VEX Cloud you own an embedded wallet, and when you turn trading on you give VEX's execution service a limited right to sign for it, which you can revoke at any time. In both, the AI never holds a key.

Can the agent trade without asking me?

Only if you choose that. By default every action that moves money waits for your approval. Desktop's Full Autonomous sessions act without asking, and the wallets you attach are the only limit. VEX Cloud's Full access acts without asking inside automatic limits; futures, token launches, CLOUD mints and transfers to a new address always ask.

Is VEX Cloud live?

Not on mainnet. It is in beta: it runs on test networks, its mainnet execution is switched off, and production is being rebuilt. You can open it and chat as a guest today. To hear when it opens to everyone, join our Telegram channel (opens in a new tab).

Where does the 0.25% fee go?

To a public treasury address. The team's policy is that 85% of the fee buys back and burns VEX and 15% funds Ecosystem Growth. It is a policy carried out from the treasury, not code. The burn ledger on the home page lists every buyback and how much VEX has truly been burned.

VEX Cloud and CLOUD: what is the difference?

VEX Cloud is the app: your agent in the browser and in Telegram. CLOUD is the token held for inference credits on VEX Cloud. Its minter is on Robinhood testnet only. Mainnet is not deployed yet (audit pending). The proposed design adds $1 of AI compute a day for each staked CLOUD; that design is not built.

Does staking pay a reward?

No. Staking is planned, and it lowers your fee, raises your limits and opens creator features. No reward is paid. CLOUD gives an allowance of AI compute, not a share of revenue.

Is VEX Arena where VEX agents compete?

No. Arena is a separate experiment with its own code. The models there trade with no approvals and no limits on purpose, so Arena results say nothing about how VEX Desktop or Cloud agents perform. Nobody can enter it. It is in development, and no round has run.

Does VEX Desktop keep trading when my computer is off?

No. Desktop works only while the app is open. If you close it or the computer sleeps, a running mission stops making progress. VEX Cloud keeps strategies running on VEX's servers while you are offline; it runs on test networks today.
