Retrieve supported chains, tokens, and live USD prices using the SDK.

​
Chains

import { useSupportedChains, getSupportedChains, getChainInfo } from '0xtrails'

// Hook: Get all supported chains
const { supportedChains, isLoadingChains } = useSupportedChains()

// Async function (non-React)
const chains = await getSupportedChains()

// Utility: Get specific chain info
const base = getChainInfo(8453)
console.log(base?.name) // "Base"

​
Tokens

import { useTokenList, useSupportedTokens, getSupportedTokens } from '0xtrails'

// All tokens across chains
const { tokens, isLoadingTokens } = useTokenList()

// Tokens for a specific chain
const { supportedTokens } = useSupportedTokens({ chainId: 8453 })

// Async function (non-React)
const allTokens = await getSupportedTokens()

​
Prices

Token prices are included when fetching balances: 
import { useTokenBalances } from '0xtrails'

const { sortedTokens } = useTokenBalances(address)

sortedTokens.forEach(token => {
  console.log(`${token.symbol}: ${token.priceUsdDisplay}`)
})
For fetching prices without balances, use the GetTokenPrices API directly.

​
Combined Example

Build a chain/token selector with live prices: 
import { useState } from 'react'
import { useSupportedChains, useSupportedTokens, useTokenBalances } from '0xtrails'
import { useAccount } from 'wagmi'

export const AssetSelector = () => {
  const { address } = useAccount()
  const [chainId, setChainId] = useState<number>()
  
  const { supportedChains } = useSupportedChains()
  const { supportedTokens } = useSupportedTokens({ chainId })
  const { sortedTokens } = useTokenBalances(address)

  return (
    <div>
      {/* Chain selector */}
      <select onChange={(e) => setChainId(Number(e.target.value))}>
        <option value="">Select chain</option>
        {supportedChains.map(chain => (
          <option key={chain.id} value={chain.id}>{chain.name}</option>
        ))}
      </select>

      {/* Token list with balances */}
      {chainId && (
        <ul>
          {supportedTokens.map(token => {
            const withBalance = sortedTokens.find(
              t => t.contractAddress === token.contractAddress && t.chainId === chainId
            )
            return (
              <li key={token.contractAddress}>
                {token.symbol} — {withBalance?.balanceDisplay ?? '0'} ({withBalance?.priceUsdDisplay ?? '$0'})
              </li>
            )
          })}
        </ul>
      )}
    </div>
  )
}
