Hi I am developing a mobile dapp. Everything seems to be on the right track however I need fake tokens on my Phantom app (devnet) to test my app. My application is not complete yet, I think need more functionality so I think I can't use real tokens. So is there any way for me to get fake tokens on Phantom mobile app? Thanks everyone!

Metaboss is the easiest way to create an SPL token with associated metadata on Solana right now: https://metaboss.rs/create.html#create

Once you create this, simply transfer it to your Phantom wallet

You can create a new token on Solana devnet. As you are creating the token on devnet, it can be used for development purposes.

Note:- We can create the new token on mainnet by pointing the network to mainnet-beta. Untill the token is listed on a trading platform, it's value is 0.

// snippet taken from https://spl.solana.com/token
import { createMint } from '@solana/spl-token';
import { clusterApiUrl, Connection, Keypair, LAMPORTS_PER_SOL } from '@solana/web3.js';

const payer = Keypair.generate();
const mintAuthority = Keypair.generate();
const freezeAuthority = Keypair.generate();

const connection = new Connection(
  clusterApiUrl('devnet'),
  'confirmed'
);

const mint = await createMint(
  connection,
  payer,
  mintAuthority.publicKey,
  freezeAuthority.publicKey,
  9 // We are using 9 to match the CLI decimal default exactly
);

console.log(mint.toBase58());

  • Sorry I tried but failed, @solana/spl-token doesn't seem to work on react-native. It throws the error: ReferenceError: Can't find variable: BigInt. Can you give more clear instructions? Oct 6, 2022 at 6:17
  • BigInt is not available on React Native. You can add a shim for that using big-integer package. Here are the details:- github.com/facebook/react-native/issues/28492 Oct 6, 2022 at 7:13
