The era of giving AI agents full access to your crypto wallet is ending. Namera, a new wallet infrastructure provider, has introduced a system where agents operate under strictly scoped permissions rather than holding your master private key. The core promise is simple: you define the budget, the allowed networks, and the expiration date, and the agent gets a key that cannot exceed those boundaries.

Scoped Keys and Hard Limits

Each agent receives its own key with immutable constraints set at issuance. These limits cover spending caps per transaction and per period, allowed token lists, and specific network access. For example, a trading bot might be limited to 0.02 ETH per swap on Ethereum, with a total allowance of 100 USDC for the period. If the agent attempts to exceed these limits, the transaction fails before signing.

The Agent Holds the Key, Not the Policy

A critical design choice is that the policy is locked at creation. The agent cannot edit its own spending limits or expiration dates. To change permissions, a human must revoke the current key and issue a new one, a process requiring passkey approval. This prevents an agent from silently escalating its privileges or extending its access beyond the intended timeframe.

Integration and Live Use Cases

Namera supports integration with major MCP clients like Claude and Codex, allowing each to have independent credentials that can be revoked separately. The platform showcases live demos for various industries, including trading desks, agentic commerce, and on-chain gaming. Use cases range from a checkout bot in a game to an allowance keeper for a wallet, all operating within their designated fences.

Key Takeaways

  • Agents get scoped keys with fixed spending limits, network access, and expiration dates set at issuance.
  • Policies are immutable; agents cannot modify their own permissions without human intervention.
  • Namera never holds signing material; session keys remain on the user's machine.
  • Integrations are available for Claude, Codex, and other MCP clients.

The Bottom Line

Finally, a sane way to let agents touch money without handing them the keys to the kingdom. This is the infrastructure layer agentic commerce has been missing.
