MTool offline tutorial

Introduction

In order to facilitate node transfer, pledge, delegation and governance and other related operations, PlatON provides PlatON MTool to assist users:

• PlatON MTool can support Ubuntu 18.04 and Windows 10. This document describes the installation and use under Windows and Ubuntu environments respectively. Users can choose according to their own resources.
• PlatON MTool provides two signature methods for pledge transactions: online signature and offline signature. This document describes offline signature operations. For online signature operations, please refer to Online PlatON MTool Tutorial.
• The main process of PlatON MTool offline signature method is: generate the file to be signed on the online machine, then sign the transaction on the offline machine, and finally send the signed transaction on the online machine.

Install PlatON MTool

In addition, this document separately introduces the operation of PlatON MTool in Windows and Ubuntu environments. Users can choose according to their own resources; the following installation methods are installation on online machines. If you install on offline machines, you can use a mobile U disk or a mobile hard disk. Copy the installation package to the offline machine, the installation method is the same as the online installation method.

Install PlatON MTool under Windows

Preparation before installation

Command line:

platon_mtool --version

If the execution result shows Cannot recognize the "platon_mtool" item as the name of a cmdlet, function, script file, or executable program. Please check the spelling of the name. If you include the path, make sure that the path is correct, and then try again, it means that there is no need to perform the following operations if the old version is not installed.

If the execution result shows the version number, timestamp and other information, it means that PlatON MTool has been installed. If PlatON MTool is an old version, you need to back up important information at this time, and then manually uninstall the old version. Operation steps:

step1. Backup directory

Put all the files under C:\platon_mtool\mtool\current\keystore to D drive or other directories other than C:\platon_mtool. After installing the new version, you need to copy the backup file back to the C:\platon_mtool\mtool\current\keystore directory.

step2. Uninstall the old version

Double-click C:\platon_mtool\unins000.exe to uninstall all old versions of PlatON MTool and other business platon_mtool.

Note: Users choose environment variables according to the system they have installed.

Detailed explanation of PlatON MTool wallet commands

Note: The follow-up command is the command format under Ubuntu. Under Windows, you need to modify $PLATON_MTOOLDIR to %PLATON_MTOOLDIR%.

Create a cold wallet

• Command line

platon_mtool account new staking

• Parameter Description

staking: The generated wallet name. After entering the same password twice, the wallet file staking.json will be generated under the directory $PLATON_MTOOLDIR/keystore after the creation is successful, and the following information will be printed:

-name: staking
-type: NORMAL
-address:

lat124xmsmd0uf5cvk7v3s36eytqezqsjfcxfw2lmr

-public key: 0x9521cd81ba28d5d1c23bb7ddb7042d146375203d35000c0289178027abd4dc09bca30257739df166201e73497485242f41d5f50d46bc3c7e4385f81bde560db0

Important write this Private Key in a safe place. It is the important way to recover your account if you ever forget your password. 4630b6d86bc74bffd4ca8cfc18bceec562cb40fc5080c258452a04a69bc1ee07

Important write this mnemonic phrase in a safe place. It is the important way to recover your account if you ever forget your password. worry jewel penalty jealous expect embark outer eternal verb rebuild rice kidney

The wallet address format is adjusted to Bech32, where:

`lat124xmsmd0uf5cvk7v3s36eytqezqsjfcxfw2lmr`: account address;

`4630b6d86bc74bffd4ca8cfc18bceec562cb40fc5080c258452a04a69bc1ee07` is the wallet private key;

`worry jewel penalty jealous expect embark outer eternal verb rebuild rice kidney` is the mnemonic phrase.

For security reasons, users need to back up the wallet's private key or mnemonic phrase (either all or one of them), which can be used for recovery when the wallet is lost. It is recommended that users back up the mnemonic phrase or private key to a secure storage medium, such as an offline machine.

Restore wallet

If the wallet file is lost, you can use the backup private key or mnemonic to restore it, as follows:

• Command line

Recovery by private key:

Prompt to enter the new wallet password and backup private key, as follows:

Enter a passphrase to encrypt your key to disk:
Repeat the passphrase:
Enter your 64bit Private Key:
4630b6d86bc74bffd4ca8cfc18bceec562cb40fc5080c258452a04a69bc1ee07

or

Recovery by mnemonic:

platon_mtool account recover -m staking

Prompt to enter the new wallet password and backup mnemonic, as follows:

Enter a passphrase to encrypt your key to disk:
Repeat the passphrase:

Offline PlatON MTool transaction process

The main process of PlatON MTool offline signature method is: generate the file to be signed on the online machine, then sign the transaction on the offline machine, and finally send the signed transaction on the online machine. Taking the transfer transaction as an example, the steps are as follows. For the operation of generating the file to be signed for other transactions, refer to the [PlatON MTool Transaction Command Details] (# PlatON MTool Transaction Command Details) chapter.

Generate transaction pending signature file

Execute on online machine:

platon_mtool tx transfer --address $PLATON_MTOOLDIR/keystore/staking_observed.json --amount "1" --recipient $to_address --config $PLATON_MTOOLDIR/validator/validator_config.json

• Parameter Description:

address: Observation wallet path for sending transactions;

amount: transfer amount, unit: LAT;

recipient: recipient address;

The following information is printed, indicating successful execution:

Transfer unsigned raw: H4sIAAAAAAAAAGWOPW/DIBRF/8ubPfDhGsdrp0oZMmSrMiCMDUGADTiGRPnvoVGHSn3T1ZHuPe8Ba/j0ozwH7iIXSXt31DHB8P0Abv3masTo3zUgFNfua4SBIIxoBVPwFgbgKeM9pLweppERJTrGXH+n1KY+5Wtujckfy247JqF2NvdWnssiYagjM49HbXWVEvzWVHAKWsg/XzTgvPshtIHkf5UlxKL2tBVkCJnZnNWtm/dyn/qbiIdrNHFlysDzUjvaypi4Xepmh2jbMor6luLnC0n7ZKsMAQAA
File generated on: $PLATON_MTOOLDIR/transaction_details/transaction_detail_20191108114241.csv

Among them, transaction_detail_20191108114241.csv is the file to be signed for the transfer transaction, which needs to be copied to the offline machine for signature;

Signature transaction

Execute on the offline machine where the cold wallet is kept:

platon_mtool offlinesign --filelocation $PLATON_MTOOLDIR/transaction_details/transaction_detail_20191108114241.csv

Note: $PLATON_MTOOLDIR/transaction_details/transaction_detail_20191108114241.csv is the file to be signed generated in the previous step, modified to the actual file to be signed.

Enter the corresponding cold wallet password and return the signed file. The content of the file is as follows:
