### Step 2 — Set Up Wallet

Check if the user already has Privy wallets using the **List Wallets** API
in `references/privy-wallets.md`.

- **Wallets found** — Present them to the user (ID, address, chain type,
attached policies). Ask whether they want to use an existing wallet or
create a new one. If they pick an existing wallet, store its ID as
`PRIVY_WALLET_ID` and skip to Step 3.

- **No wallets found** (or user wants a new one):

1. **Policy (recommended)** — Ask the user if they want to configure a
policy before creating the wallet. Explain that policies enforce
spending limits, chain restrictions, and contract allowlists at the
TEE level. If yes, gather their preferences (chains, limits,
allowlists) and create the policy following `references/privy-policies.md`.
Store the returned ID as `PRIVY_POLICY_ID`.

2. **Wallet creation** — Ask the user which chain type they need
(`ethereum` for all EVM, `solana`). Create the wallet
following `references/privy-wallets.md`, attaching the policy if one
was configured. Store the returned ID as `PRIVY_WALLET_ID` and
confirm the address to the user.

## Example 4 — Staking with Validator Selection

**User:** I want to stake 10 ATOM on Cosmos Hub.

**Agent steps:**
1. Calls `yields_get("cosmos-atom-cosmos-staking")`
2. Enter schema has `validatorAddress` field with `optionsRef` — must call
validators endpoint
3. Calls `yields_get_validators("cosmos-atom-cosmos-staking")`
4. Presents options:

```

| 1 | Chorus One | 5% | 18.4% |
| 2 | Figment | 5% | 18.4% |
| 3 | Simply Staking | 5% | 18.3% |
```

**User:** Use Chorus One.

**Agent steps:**
1. Calls `actions_enter("cosmos-atom-cosmos-staking", "0x...",
'{"amount":"10","validatorAddress":"cosmosvaloper1..."}')`
2. Single staking transaction → Privy → CONFIRMED
3. Confirms: "10 ATOM staked with Chorus One. Earning ~18.4% APY."
