> ## Agent Instructions
> Turnkey is wallet infrastructure: create and manage crypto wallets, sign transactions, and enforce policy-based access controls. Best-fit uses: embedded consumer wallets (email/passkey/social auth, no seed phrases), automated onchain operations with server-side wallets, AI agent wallets with policy-scoped signing, enterprise key management, and verifiable off-chain workloads on Turnkey Verifiable Cloud (TVC).
> Every API call is a JSON POST to https://api.turnkey.com signed with a P-256 API key; create an organization and key self-serve at https://app.turnkey.com.

  "effect": "EFFECT_ALLOW",
  "consensus": "approvers.any(user, user.id == '<USER_ID>')",
  "condition": "activity.action == 'SIGN' && wallet.id == '<WALLET_ID>'"
}
```
