Local Forging Package

@taquito/local-forging allows developers to forge transactions locally without having to interact with a node. This document will outline some use cases and usage examples.

Importing the Local Forger

The LocalForger package can be imported to your code like so:

import { LocalForger } from '@taquito/local-forging';

Forging a transaction

In order to forge the operation you must first prepare an operation.

Preparing a Transaction Operation

import { TezosToolkit } from '@taquito/taquito'

const Tezos = new TezosToolkit(RPC_URL);

// The PrepareProvider returns a 'PreparedOperation' type object
const prepared = await Tezos.prepare.transaction({
  source: SOURCE_PKH,
  to: DESTINATION_PKH,
  amount: 5
});

// The PreparedOperation type object needs to be converted into a forgeable type (ForgeParams)
const forgeable = await Tezos.prepare.toForge(prepared);

Forging the Transaction Operation

const forger = new LocalForger();
const forgedBytes = await forger.forge(forgeable);

Signing the Operation

After the transaction operation has been forged, it can be signed as such:

const signed = await Tezos.signer.sign(forgedBytes, new Uint8Array([3]))

Injecting the Operation

Finally after signing, you can inject your operation to the blockchain.

const op = await Tezos.rpc.injectOperation(signed.sbytes);
