Stop giving agents
your private keys

Signet creates on-chain session scopes for AI agents. Granular. Time-limited. Enforced by smart contracts. Your Ledger stays in control.

The vulnerability

Every AI agent today holds a loaded gun

To transact autonomously, agents need your private key. One prompt injection, one compromised model, one bad API call — and there are no guardrails. No limits. No undo.

!Without Signet

—Agent holds full private key access

—No spending limits or boundaries

—Prompt injection drains everything

—Zero human oversight at runtime

✓With Signet

—Agent gets a scoped session key

—Spend limits enforced on-chain

—Contract and function restrictions

—Out-of-scope? Ledger asks you first

How it works

Three steps to safe autonomy

01

Connect your Ledger

Your hardware wallet is your identity and your authority. Plug in via USB — private keys never leave the secure element. Your EOA becomes a smart account through EIP-7702 delegation.

02

Define agent scopes

Set which contracts the agent can call, which functions it can invoke, how much it can spend, and for how long. Every parameter is written to smart contract storage — not an API layer, not a database. The EVM itself enforces your rules.

03

Monitor and approve

Agents operate freely within their granted bounds. When a transaction exceeds the scope — higher value, unauthorized contract, expired session — it's escalated to your Ledger for explicit approval. You stay in the loop without being in the way.

Stop sharing keys.
Set scopes.

Connect your Ledger and grant your first agent session in under a minute.
