Astral

Wallet for AI trading agents

A trading wallet your AI agent can't blow up.

Connect Grok, Claude or any MCP agent and let it trade on Base, Arbitrum, BNB Chain, Polygon and Robinhood Chain. The wallet enforces your limits on-chain, you hold the keys, and every signature is post-quantum.

01Setup

Set it up once. The agent takes it from there.

No browser extension, and no seed phrase to hand to a bot. The agent gets its own key and its own rules.

    1

    Create the agent

    Pick a network, a daily budget, the tokens it may touch and the size above which it has to ask you. You get a one-time connect code.

    2

    Paste one message into your AI

    It installs quantos-mcp, which creates the agent's key on that machine. We never see it.

    Message to Grok Bot or Claude

    Add a stdio MCP server named "astral" with the command "npx -y quantos-mcp" and the environment variable QUANTOS_CONNECT_CODE=QTOS-7F3K-92XA.

    3

    Fund it, then write the strategy

    Send USDC and a little gas (ETH, BNB or POL) to the agent's address. Describe the strategy in plain words, like the one replayed above. It runs around the clock.

02Guardrails

A prompt can fool a model. It can't fool the wallet.

A hidden line in a web page or a token name can talk an AI into almost anything. Astral checks every request on-chain before a cent moves, so the worst case is a refused transaction.

Daily budget
Set $1,000 a day and the wallet refuses dollar 1,001. No retry gets around it.
Token list
The agent trades the tokens you picked. Allow any token and it can buy memecoins too, only with those tokens, never to send away.
Approval line
Above the size you choose, a trade waits for your OK on your phone or laptop.
Pause
One tap stops every trade. Withdrawing still works while paused.
03Keys

Keys only you hold. Signatures a quantum computer can't forge.

ML-DSA-44

NIST's post-quantum signature standard (FIPS 204, 2024). Every agent and owner signature uses it; no classical key controls the wallet.

0 keys

on our servers. The agent's key stays on the machine running your AI, yours comes from your 24 words, in your browser.

5 networks

Same contract addresses everywhere, source verified on Sourcify. Swaps routed by 0x; network fees are usually a few cents.

How the quantum safety works
1%

per trade. No subscription, no deposit fee, nothing to pay while the agent waits.
