createWallet

Function Signature

Future<PortalAddresses> createWallet()

Description

Generates a new MPC wallet and returns its addresses. The private keys are split across multiple parties and never exist in full on the device.

Parameters

This method takes no parameters.

Returns

PortalAddresses - An object containing:

Property	Type	Description
`ethereum`	`String?`	The Ethereum/EVM address
`solana`	`String?`	The Solana address
`bitcoin`	`PortalBitcoinAddressInfo?`	The Bitcoin P2WPKH mainnet and testnet addresses
`stellar`	`String?`	The Stellar address
`tron`	`String?`	The Tron address
`xrpl`	`String?`	The XRP Ledger address

bitcoin, stellar, tron and xrpl are null when the client has no address for that chain. They’re looked up after the wallet is created. If that lookup fails, createWallet still succeeds and these fields are null. Call getAddresses() to fetch them.

Example

import 'package:portal_flutter/portal_flutter.dart';

final portal = Portal();

final addresses = await portal.createWallet();

print('EVM address: ${addresses.ethereum}');
print('Solana address: ${addresses.solana}');

Errors

Code	Description
`NOT_INITIALIZED`	Portal was not initialized before calling this method
`WALLET_EXISTS`	A wallet already exists for this client
