# Overview
> Warp is Rhinestone's intent routing and execution engine for crosschain transactions.
**Warp (Rhinestone Intents)** is an intent routing and execution engine. With a single signature, your users can move funds and execute calls across any supported chain in under 2 seconds.
## Capabilities
* **Crosschain transactions**: execute calls on any destination chain using funds from any source chain, in a single signature
* **Gas abstraction**: sponsor gas, bridging, and swap fees for your users, or let them pay in any supported token — no ETH required
* **Inbuilt swaps**: bridge and swap in one intent using solver liquidity, or inject your own DEX aggregator
* **Unified balance**: aggregate a user's funds across all supported chains to fund any transaction automatically
* **Non-custodial**: assets stay in the user's account until the moment of execution
## What you can build
* **Chain-abstracted wallets**: let users transact anywhere from a single account, regardless of where their funds sit
* **Crosschain DeFi**: deposit into vaults, provide liquidity, or execute trades on any chain without manual bridging
* **Automated portfolio management**: use session keys and intents together to execute strategies on behalf of users without per-transaction prompts
* **AI agents**: give agents a crosschain account with scoped permissions to execute onchain tasks across any supported chain
## SDK or API?
Warp is accessible via the Rhinestone SDK (TypeScript) or directly via the REST API.
| Scenario | Use | Why |
| ---------------------------------------------------- | ------------------------------- | -------------------------------------------------------------------------------------------------------------------- |
| Building a new wallet or dapp in TypeScript | [SDK](/smart-wallet/quickstart) | Handles account creation, signing, and submission out of the box |
| Server-side automation or AI agent | [API](/intents/quickstart) | Full control, no browser dependency, any language |
| EOA users, no smart account | [API](/intents/quickstart) | API handles EOA signing natively |
| Existing smart account users (not on Rhinestone SDK) | [API](/intents/quickstart) | Install [Intent Executor](/intents/guides/installing-intent-executor) first, then use API with smart account signing |
| Fastest integration from zero | [SDK](/smart-wallet/quickstart) | One package, batteries included |
| Non-JS environment (Python, Rust, Go) | [API](/intents/quickstart) | REST API works with any HTTP client |
Already using the Rhinestone SDK? Your wallet quickstart covers intents. Start there.

You'll need a Rhinestone API key for mainnet usage. [Request one here](https://tally.so/r/wg22x4). Testnets work without a key.
