📦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.

Quick Start

Set up the SDK

Firstly, create SDK config with your integrator string.

import { createConfig } from '@lifi/sdk'

createConfig({
  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,
