 Most developers should use the [Agent Client](/sdk/agent-client) instead. These primitives are for power users building custom stealth address integrations on Stellar.

 - **Account creation:** Stellar requires accounts to exist with a minimum balance (1 XLM). Sending to a new stealth address uses `Operation.createAccount`, not `Operation.payment`.
 - **Announcements:** Come from Soroban contract events via `sorobanServer.getEvents()`, not a subgraph. Use `fetchAnnouncements("stellar")` to handle this automatically.
 - **Signing:** Must use `signWithScalar()` / `signStellarTransaction()` because stealth scalars aren't valid seeds for `Keypair.fromRawEd25519Seed()`.
+- **Fee bumps:** Withdrawals can be wrapped in a sponsored fee-bump transaction when the stealth account should not keep extra XLM only for fees.
