portal.api

The api property contains an instance of the PortalApi class, which has a number of helper methods to facilitate the retrieval of relevant application data from the Portal REST API.

​
portal.api.buildTransaction

const txDetails = await portal.api.buildTransaction(
  '0xDestinationAddress',
  'USDC', // Friendly token name, or token address (mint address for Solana)
  '1', // Sends 1 USDC
  'sepolia', // Friendly chain or CAIP-2 chainId
)

​
portal.api.getNFTs

Fetches a list of non-fungible tokens (NFTs). The response is an array of objects where each object represents a unique NFT. 
const nfts = await portal.api.getNFTs()

​
portal.api.getTransactions
