Can an AI agent have its own crypto wallet?

Technically yes — it can hold keys and sign. Legally, the wallet should be owned by a company, not the agent, because the agent isn't a legal person. The agent operates the wallet as an authorized delegate, within documented limits.

Whose money is in the agent's wallet?

It should be the company's. If the wallet sits under a company that owns the agent, the funds and any liability are the company's — not your personal assets. That's the whole point of putting an entity around the agent.

How do I limit what the agent can spend?

With a machine-readable mandate the agent reads at runtime (per-transaction and per-period caps, allowlists, prohibited actions, fail-closed), a kill-switch, and human approval for high-value actions. Custody via multisig adds a hard control.

How to give your AI agent a wallet (legally)

Spinning up a wallet for your agent is the easy part — generateKey() and you're done. The part that bites later is whose money it is, who's liable, and how you stop it. Here's the setup that holds up.

WalletsAI agentsCustody · 6 min read

The one rule: the company owns the wallet, not the agent. The agent operates it as an authorized delegate, within limits it reads at runtime. That keeps the funds and the liability inside an entity — off your personal balance sheet.

Why "just give it a wallet" backfires

A key in your agent's environment with real funds behind it has no legal wrapper. If it gets drained, makes a bad payment, or is used in a transaction that goes sideways, the money and the consequences trace back to you, personally — because the agent isn't a legal person and can't bear liability. The fix isn't more code; it's putting a company around the wallet.

The setup, step by step

Put a company around it. Form an entity that owns the agent and the wallet — for value-handling agents, a Nevis LLC (asset protection) is the default. A human is the beneficial owner.
Make the wallet company-owned. Record the wallet(s) in a Wallet Authority Schedule that binds them to the entity. The funds are the company's, not yours.
Document the agent's authority. An Agent Mandate + Power of Attorney say what the agent may do with the wallet — so it's a delegate, not a rogue key.
Enforce limits at runtime. A machine-readable mandate (JSON) the agent loads on every action: per-transaction and per-day caps, allowlists, prohibited categories, fail-closed if it can't verify, and a heartbeat/status check.
Add a kill-switch + approvals. A named human (or multisig) can suspend the agent instantly; high-value or out-of-scope transfers require human approval.
Prefer multisig custody. So no single compromised key can move everything — a hard control on top of the soft (mandate) ones.
Keep logs. Immutable records of the agent's decisions and transactions — your audit trail.

Soft limits vs. hard limits

Control	Type	Stops what
Machine-readable mandate (caps, allowlists, fail-closed)	Soft (in-agent)	Honest mistakes, drift, prompt-injection within scope
Multisig custody / approval gates	Hard (on-chain / human)	A compromised key or a rogue action
Kill-switch / revocation endpoint	Hard	Anything, immediately

You want both. The mandate keeps a well-behaved agent inside the lines; multisig + kill-switch are what save you when something is wrong.

Prompt-injection note: assume the agent will at some point be told to exceed its authority. The mandate should treat instructions to bypass limits as unauthorized by default (fail-closed), and the real protection is the hard controls (multisig, approval, kill-switch).

Where this comes from

Steps 1–7 above are exactly what an Agent Company packages: the Nevis LLC (1), a Wallet Authority Schedule (2), the Agent Mandate + Power of Attorney (3), the machine-readable mandate with fail-closed + revocation (4–5), all generated for your agent. Multisig custody, approvals, and incident response stay in your ops.
