@taquito/signer

Taquito Signer package

Storing private keys in memory is suitable for development workflows but risky for production use-cases! Use the InMemorySigner appropriately given your risk profile

@taquito/signer is an npm package that provides developers with signing functionality for Taquito. It can be injected as follows:

Loading an unencrypted private key

If you configure Taquito this way, you will now be able to use every function that needs signing support.

import { InMemorySigner } from '@taquito/signer';
import { TezosToolkit } from '@taquito/taquito';

const Tezos = new TezosToolkit('https://YOUR_PREFERRED_RPC_URL');

Tezos.setProvider({ signer: await InMemorySigner.fromSecretKey('your_private_key') });

Loading an encrypted private key with a passphrase

If your private key is encrypted, you can specify a passphrase to decrypt it. Doing so will automatically decrypt the key and allow you to use the signer to sign transactions.

import { InMemorySigner } from '@taquito/signer';
import { TezosToolkit } from '@taquito/taquito';

const Tezos = new TezosToolkit('https://YOUR_PREFERRED_RPC_URL');
Tezos.setProvider({
  signer: await InMemorySigner.fromSecretKey('your_private_key', 'your_passphrase'),
});

Using a testnet faucet key

To load a faucet key (available from https://faucet.tzalpha.net/) for working a public testnet use the importKey function. You can do so as follows:

import { TezosToolkit } from '@taquito/taquito';
import { importKey } from '@taquito/taquito-signer';

const Tezos = new TezosToolkit('https://YOUR_PREFERRED_TESTNET_RPC_URL');

// A key faucet, similar to what is available from https://faucet.tzalpha.net/
const FAUCET_KEY = {
  mnemonic: [
    'cart',
    'will',
    'page',
    'bench',
    'notice',
    'leisure',
    'penalty',
    'medal',
    'define',
    'odor',
    'ride',
    'devote',
    'cannon',
    'setup',
    'rescue',
  ],
  secret: '35f266fbf0fca752da1342fdfc745a9c608e7b20',
  amount: '4219352756',
  pkh: 'tz1YBMFg1nLAPxBE6djnCPbMRH5PLXQWt8Mg',
  password: 'Fa26j580dQ',
  email: '[e-mail]',
};

importKey(
  Tezos,
  FAUCET_KEY.email,
  FAUCET_KEY.password,
  FAUCET_KEY.mnemonic.join(' '),
  FAUCET_KEY.secret
);
// Your Tezos instance is now operably configured for signing with the faucet key.

If you configure Taquito this way, you will now be able to use every function that needs signing support. The operation will be signed automatically using the signer (no prompt)
