📦Install LI.FI SDK

Integrate our LI.FI SDK to your dApp/Wallet/Swap UI

The LI.FI SDK package provides access to the LI.FI API to find and execute the best on-chain and cross-chain routes across various bridges and exchanges.

Our API is free to use but rate-limited.

Please see Rate Limits & API Key if you need more requests per second.


To get started, install the latest version of LI.FI SDK.

yarn add @lifi/sdk

Check out our complete examples in the SDK repository, and feel free to file an issue if you encounter any problems.

As an integrator, you can monetize your LI.FI SDK integration and collect fees. See our monetization guide for more information.

Contact our business partnerships team to discover how you can partner with us and integrate LI.FI into your platform.

Quick Start

Set up the SDK

Firstly, create SDK config with your integrator string.

import { createConfig } from '@lifi/sdk'

  integrator: 'Your dApp/company name',

Request a Quote

Now you can interact with the SDK and for example request a quote.

import { ChainId, getQuote } from '@lifi/sdk'

const quote = await getQuote({
  fromAddress: '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045',
  fromChain: ChainId.ARB,
  toChain: ChainId.OPT,
  fromToken: '0x0000000000000000000000000000000000000000',
  toToken: '0x0000000000000000000000000000000000000000',
  fromAmount: '1000000000000000000',
