Wallets Integration

With Mesh, you can initialize a new wallet with:

Wallet as a Service​

UTXOS wallet-as-a-service (WaaS) solution provide a seamless way for users to transact on-chain. Developers can integrate social logins and other familiar experiences into their applications, making onboarding fast and effortless. Users can create non-custodial wallets (the user owns the key and have full control over their digital assets) instantly without needing to manage private keys. Users can also recover their wallets and export their private keys at any time.

Wallet key management system uses Shamir’s Secret Sharing to split the private key into multiple parts. The parts are stored in different locations, such as the user’s device and encrypted in the server. Neither UTXOS nor the developer’s application has access to the user’s keys. The private key is reconstructed only on the user’s device during transaction signing, in an isolated iframe, which persists in-memory and is destroyed after the transaction is signed.

Overall, the integration with a wallet-as-a-service solution provides a self-custody wallet to end users and accelerates the time-to-market for developers.

To get started with UTXOS wallet-as-a-service, visit the UTXOS documentation. See also our UTXOS integration guide for detailed setup instructions and examples.

Browser Wallet​

Browser Wallet is use for connecting, queries and performs wallet functions in accordance to CIP-30, which defines the API for dApps to communicate with the user's wallet.

To use Browser Wallet is simple, just import BrowserWallet execute the APIs, for example:

// import BrowserWallet
import { BrowserWallet } from '@meshsdk/core';

// connect to a wallet
const wallet = await BrowserWallet.enable('eternl');

// get assets in wallet
const assets = await wallet.getAssets();
APIs

import { MeshWallet } from '@meshsdk/core';

const wallet = new MeshWallet({
  networkId: 0,
  fetcher: blockchainProvider,
  submitter: blockchainProvider,
  key: {
    type: 'cli',
    payment: '5820aaca553a7b95b38b5d9b82a5daa7a27ac8e34f3cf27152a978f4576520dd6503',

  },
});

Load with mnemonic phrases​

import { MeshWallet } from '@meshsdk/core';

const wallet = new MeshWallet({
  networkId: 0,
  fetcher: blockchainProvider,
  submitter: blockchainProvider,
  key: {
    type: 'mnemonic',
    words: ["solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution"],
  },
});

Load with private keys​

import { MeshWallet } from '@meshsdk/core';

const wallet = new MeshWallet({
  networkId: 0,
  fetcher: blockchainProvider,
  submitter: blockchainProvider,
  key: {
    type: 'root',
    bech32: 'xprv1cqa46gk29plgkg98upclnjv5t425fcpl4rgf9mq2txdxuga7jfq5shk7np6l55nj00sl3m4syzna3uwgrwppdm0azgy9d8zahyf32s62klfyhe0ayyxkc7x92nv4s77fa0v25tufk9tnv7x6dgexe9kdz5gpeqgu',
  },
});
