Key sharding for AI agents is the right architecture. The real problem in agent wallets is not custody — it is authorization policy. Who decides when the agent can spend? A behavioral policy layer that gates transactions based on context (not just signatures) is where the actual security lives. Most agent wallet projects skip this and just wrap a multisig, which gives you key management without decision management. Claw Wallet adding behavioral policies on top of sharding means they understand the threat model: the agent itself might be compromised, not just the keys.
