## What it is
Rango Exchange's TypeScript SDK for integrating cross-chain swap and bridge aggregation into applications. It provides both a basic single-step API wrapper and a main multi-step SDK for building transactions across many blockchains.

## Use cases
- integrate cross-chain swaps into a web3 app
- build a crypto bridge aggregator frontend
- swap tokens between ethereum and solana programmatically
- embed defi bridging in a nodejs service
- get cross-chain routing quotes via API
- build a multi-step cross-chain transaction flow

## When to choose
- you need cross-chain swap/bridge routing across many chains in a TypeScript or Node.js project
- you want to build on top of Rango Exchange's aggregator API
- you need both single-step and multi-step transaction handling

## When to avoid
- you need on-chain swap logic without relying on Rango's hosted API
- you work outside the JavaScript/TypeScript ecosystem
- you need a fully decentralized, self-custodied aggregator with no third-party API dependency
