# Developer guides

Use the Curvy TypeScript SDK to add private balances, transfers, swaps, withdrawals, and recovery flows to an application.

## Start here

1. [Install and configure the SDK](./installing-the-sdk.md).
2. [Authenticate an account](./authentication.md).
3. [Read shielded balances](./querying-balances.md).
4. [Estimate and execute an intent](./interacting-with-assets.md).
