# Overview

> Ship on Stable: wallets and accounts, payments, smart contracts, and AI agents. Start with the quick start or jump straight to the capability you need.

New to Stable? Run the [Quick start](/en/tutorial/quick-start) first. It takes five minutes and sends a testnet transaction so the rest of the tab has something to plug into.
