## Before you call either

### Coinbase MCP server (Coinbase for Agents)

1. Call `coinbase_portfolios_list` first and name the portfolio on every order; an order without one falls back to the default portfolio and fails if it isn't granted
2. Send a fresh `client_order_id` with each order and reuse it on retry, so a dropped connection doesn't place a second order
3. Preview with `coinbase_orders_preview` and confirm with the person before `coinbase_orders_create`; equity previews may be unavailable
4. Use `ETH-USDC`-style pairs when buying with a USDC balance, and `base_size` in contracts for futures
5. Agree a spending budget before `coinbase_x402_fetch`, set `max_amount`, and keep the `idempotency_key` for any retry; settled payments can't be reversed

### Privy Wallets (server wallets, agent wallets, policy engine)

1. Add a rule for every RPC method the agent needs; a wallet with a policy denies anything unlisted
2. Pair a rolling cap with a lower per-transaction cap, since aggregations update only after signing
3. Send an idempotency key on `/rpc`, `/transfer` and `/wallets` calls; reusing one with a changed body returns 400
4. Set `maxValue` on the x402 or MPP client for every request
5. Retry a `transaction_broadcast_failure`; don't retry a `policy_violation`
