Dedicated agent wallet

Keep the bot’s spend wallet separate from long-term holdings. Fund only what one bad run can lose. Revoke and rotate before you raise the balance. Cold store stays on hardware you approve; the hot agent wallet is the only path the agent can reach.

Answer first

Before Cursor or Grok can move money, open a dedicated agent wallet (or brokerage Agentic sleeve) whose only job is agent spend. Keep savings, payroll, and cold-store keys outside that path. Fund only the ceiling for this day or project, keep review before place as a standing rule, and empty or revoke that path before you put more money in. Agent Lane publishes the checklist. We do not hold keys, place trades, or run your agents.

What this page is

A short operator guide for why the spend wallet stays separate — the wallet half of the shield that sits beside agent spend caps, review before place, the crypto shield, the brokerage shield, and x402 buyer basics. Pair it with the shared-box checklist and a separate browser profile for the agent when the agent runs on a shared computer.

We are a publisher, not a wallet or trading desk. Product screens change; confirm balances and tool names on the official page before you put money in.

Two piles, one shield

• Long-term holdings. Cold store, savings, payroll, seed phrases you would mourn — outside the shield. The agent never sees that login or key.
• Agent spend. A hot wallet or Agentic account with one job: money this run may lose. Inside the shield, behind review before place.
• The gap is the shield. Separation is not a product name. It is the rule that one bad prompt cannot drain the main stash.

How to keep a dedicated agent wallet

1. Name two piles. Label long-term holdings and agent spend. They never share a login, key, or funded sleeve the bot can reach.
2. Open a hot spend path. Create or fund a dedicated wallet or brokerage Agentic account whose only job is agent money.
3. Park cold storage elsewhere. Keep seed phrases and long-term balances on a hardware wallet or other cold store the agent cannot see or sign with.
4. Fund only one bad run. Move in only the ceiling for this day or project. Check the balance before the session, not after. Detail: fund the session ceiling.
5. Require review before place. Standing rules: amount, destination, and asset shown before any place or signature. No “just place it” or “don’t ask.”
6. Revoke and rotate before you raise. Disconnect connectors, empty or move the spend sleeve, revoke grants and rotate tokens, then raise the balance or dig into a bad prompt. Detail: rotate before you raise the balance.

Hot agent wallet vs hardware cold store

• Hot agent wallet. The balance the bot (or its signer) can spend this session. Small by design. Empty when the project ends — and overnight/idle: empty the sleeve overnight.
• Hardware / cold store. Long-term holds and seed phrases on a device or vault you approve — never pasted into chat, .env, or the agent machine when you can avoid it. Detail: never share a seed phrase with an agent.
• Prefer a signer you approve. A raw key in .env on the shared box is a last resort, not the default.
• One login, one sleeve. Do not share that spend wallet across housemates or a second person’s agent.

Fund only what one bad run can lose

The funded balance is the last hard stop if a rule fails. Put in only the ceiling for this day or project. Refill yourself after you read the receipts — do not leave a fat balance “for later.” Pair the wallet with session and daily maxes from agent spend caps.

Revoke and rotate before you raise the balance

Deepen this habit: Rotate before you raise the balance. End of session / overnight: Empty the sleeve overnight. Full incident order: Revoke before you debug.

1. Disconnect live brokerage and payment connectors (and any payer MCP) from Cursor and Grok.
2. Lock or sign out of the agent apps on that computer.
3. Move leftover funds off the spend wallet or Agentic sleeve to a place the agent cannot trade or sign — or empty it.
4. Revoke login grants and rotate tokens that lived beside those connectors.
5. Only then fund a higher ceiling or dig into a bad prompt. Debugging while the pipe is still open is how a second spend lands.

FAQ

What is a dedicated agent wallet?

A dedicated agent wallet is a hot spend path whose only job is agent money — brokerage Agentic sleeve, on-chain spend wallet, or payer balance the bot can reach. Long-term holdings, savings, payroll, and cold-store keys stay outside that path so one bad run cannot touch the main stash.

Why keep the agent wallet separate from long-term holdings?

A key or session the agent can see is a key or session the next prompt, log, shared user, or leaked chat can spend. Separation is the shield: fund only what one bad run can lose inside; keep cold storage and personal accounts outside. Review before place still sits on the gate.

How much should I fund the agent wallet?

Fund only the ceiling for this day or project — the amount you can afford to lose if a prompt, connector, or signature goes wrong. Check the balance before the session. Refill yourself after you read receipts. Pair the funded balance with session and daily maxes from the agent spend caps guide.

Hardware wallet vs hot agent wallet — which is which?

Use a hardware wallet (or other cold store you approve) for long-term holds and seed phrases the agent must never see. See never share a seed phrase with an agent. Use a separate hot spend wallet or Agentic account for agent runs. Prefer a signer you approve over a raw key in .env on the agent machine.

Should I revoke and rotate before raising the balance?

Yes. Disconnect live connectors and payer MCPs, lock or sign out of agent apps, empty or move funds off the spend wallet, revoke grants, and rotate tokens before you put more money in or raise caps. Raising the balance while the pipe is still open is how a second spend lands during debug. Own guide: rotate before you raise the balance.

Where do I apply this next?

Hard dollar limits: agent spend caps. On-chain hygiene: shield crypto spend. Brokerage MCP path: shield brokerage spend. Paying for a web request: x402 buyer basics. Shared computer and connectors: shared-box checklist. Seeds: never share a seed phrase with an agent. Agent Lane publishes the checklist; we do not hold keys or place trades.
