USENAMI / SIGNER

AI agents can't leak
your keys.

Your CEX & DEX API keys stay inside an AWS Nitro Enclave. Every order is checked against your policy (venue, action, and size) before a signature ever exists. A prompt-injected or compromised agent can propose a trade; it can't sign one outside your policy or touch a withdrawal at all.

The problem

Today, your agent holds the API key.

Every AI-agent framework that touches an exchange loads the key into the agent process — env vars, packages, tool calls, shell history. Signer moves it out of reach.

Prompt injection
A poisoned page or tool output tells your agent to leak secrets. There is nothing to leak — the key is not in the agent's reachable memory.
Supply-chain attack
A malicious dependency reads whatever the agent process can read. That no longer includes your exchange credential.
Infostealer malware
Searches .env, shell history, and process memory on the agent's host. Finds nothing usable — the key lives in another VM.
How it works

The key stays in the enclave. Always.

01
Your agent proposes an order
It calls place_order over MCP — from Claude Desktop, Cursor, ElizaOS, or any MCP-aware client. It never touches a credential.
02
The enclave checks the policy
Allowed venues, deny-by-default. Provisioned policy-wrapped tokens are bounded further — per-asset and per-period caps, fixed at onboarding.
03
The enclave signs — the key never leaves
The signing secret is used inside an AWS Nitro Enclave and never leaves it. The running code's PCR0 is published — verify it against AWS's signed attestation.

For design partners

Early access, provisioned per partner.

Signer runs with early design partners on testnet. Tell us what you trade and which venues you need, and we set up a policy-bound token. Your agent connects from any MCP client:

{
  "mcpServers": {
    "signer": {
      "command": "npx",
      "args": ["-y", "@usenami/signer-mcp"],
      "env": { "SIGNER_API_TOKEN": "<provisioned at onboarding>" }
    }
  }
}
