Overview

The 1inch Cross-Chain SDK supports atomic swaps across multiple EVM chains and Solana, enabling trustless cross-chain token transfers.

​
Native Token Addresses

For EVM chains, use the following address for native tokens: 
const NATIVE_TOKEN = '0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee'
Or use the SDK constant: 
import { EvmAddress } from '@1inch/cross-chain-sdk'

const nativeToken = EvmAddress.NATIVE.toString()
For Solana: 
import { SolanaAddress } from '@1inch/cross-chain-sdk'

const nativeSOL = SolanaAddress.NATIVE.toString()

​
Usage Examples

​
Check if Chain is EVM

import { isEvm, NetworkEnum } from '@1inch/cross-chain-sdk'

console.log(isEvm(NetworkEnum.ETHEREUM)) // true
console.log(isEvm(NetworkEnum.POLYGON)) // true
console.log(isEvm(NetworkEnum.SOLANA)) // false

​
Check if Chain is Solana

import { isSolana, NetworkEnum } from '@1inch/cross-chain-sdk'

console.log(isSolana(NetworkEnum.SOLANA)) // true
console.log(isSolana(NetworkEnum.ETHEREUM)) // false

​
Validate Chain Support

import { isSupportedChain, NetworkEnum } from '@1inch/cross-chain-sdk'

console.log(isSupportedChain(NetworkEnum.ETHEREUM)) // true
console.log(isSupportedChain(NetworkEnum.POLYGON)) // true
console.log(isSupportedChain(999)) // false

​
Cross-Chain Combinations

// EVM to EVM
const quote1 = await sdk.getQuote({
  srcChainId: NetworkEnum.ETHEREUM,
  dstChainId: NetworkEnum.POLYGON,
  // ...
})

// EVM to Solana
const quote2 = await sdk.getQuote({
  srcChainId: NetworkEnum.ETHEREUM,
  dstChainId: NetworkEnum.SOLANA,
  // ...
})

// Solana to EVM
const quote3 = await sdk.getQuote({
  srcChainId: NetworkEnum.SOLANA,
  dstChainId: NetworkEnum.ARBITRUM,
  // ...
})
