Command Line Wallet Tool

iwallet is the command line tool for IOST blockchain. You can use this tool to connect IOST blockchain to transfer coins, create accounts, query balance or call contracts.

Both iwallet and API use RPC API inside and they have similar features.

Install

You need to install golang firstly before you get iwallet by the following command:

go install github.com/iost-official/go-iost/v3/cmd/iwallet@latest

Or use iwallet inside docker directly:

docker run --rm iostio/iost-node iwallet --help

Please install Node.js if you want to publish contracts onto the blockchain.

Basic Usage

You could run iwallet and get the following usage information once you finish the steps above:

Use "iwallet system [command] --help" for more information about a command.

In above examples, you may find some flags (like --account) have the corresponding shortcut flag (like -a) that has exactly same effect. And there are some commands that would have corresponding shortcuts (like system has an alias sys). But for clarity, we will use the full name flags and full name commands instead of shortcuts in following sections.

The verbose information of a command will commonly include RPC connecting information, elapsed time and transaction details if it contains a transaction sending action. We will omit the verbose information in following output examples for concise.

Basic Features

Query Account

iwallet can be used to query account information including balance, RAM, GAS etc.

Output format will be same as getAccountInfo API.

The --server flag inside the following command indicates the remote IOST server. If you launch server locally, yon can skip this flag to use default value (localhost:30002) - we will omit this flag in following sections.

iwallet --server 127.0.0.1:30002 balance xxxx

Call Contract

Import Account

An account must be imported before calling any contracts. It is done locally without any interaction with blockchain.

iwallet account import <account_id> <private_key>

Usage - Call contract

iwallet --account <account_name> [flags] call <contract_name> <function_name> '["arg1","arg2",...]'
FlagDescriptionDefault
accountwho calls the contract< user specified >
gas_limitmax gas allowed for the calling1000000
gas_ratiotransaction with bigger gas_ratio will be executed earlier1.0
amount_limitall token amount limits (e.g. iost:300.0|ram:2000)*:unlimited

Sample - Transfer token by calling contract

Call function "transfer" of contract "token.iost" by account "admin".
The last argument of this command is the parameters for function "transfer" which are token type, payer, receiver, amount and optional memo.

iwallet --account admin call 'token.iost' 'transfer' '["iost","admin","lispczz","100",""]'

Sending transaction...
Transaction has been sent.
The transaction hash is: CzQi1ro44E6ysVq6o6c6UEqYNrPbN7HruAjewoGfRTBy
Checking transaction receipt...
SUCCESS!

Create Account

Creating account would generate a random keypair and save the private key to ~/.iwallet/YOUR_ACCOUNT_ID.json.

Usage - Create account

All flags for calling contract are needed since creating new account needs calling contracts.

iwallet --account <account_name> [flags] account create <new_account_name>
FlagDescriptionDefault
accountwho create the new account< user specified >
initial_ramram amount bought for new account by creator1024
initial_gas_pledgeIOST amount pledged for gas for new account by creator10
initial_balanceIOST amount transferred to new account by creator0

Sample - Create account

iwallet --account admin --amount_limit "ram:1000|iost:10" account create lispczz3 --initial_balance 0 --initial_gas_pledge 10 --initial_ram 0

Sending transaction...
Transaction has been sent.
The transaction hash is: 6519HCdkDpB29FqMeGWQVY82fjicWyjbwdV99CPNeRCW

Active permission key: 7Z9US64vfcyopQpyEwV1FF52HTB8maEacjU4SYeAUrt1

Publish Contract

To publish a javascript contract, you need to generate abi file firstly, and then publish javascript file and abi file onto blockchain.

Generate ABI

The following command will generate file example.js.abi. (Note that make sure you have installed node.js and already ran the command npm install inside folder iwallet/contract.)

iwallet compile example.js

Usually you need to adjust the abi file that just generated since the parameter type and amount limit of action always need to be adjusted according to your actual usage.

Publish Contract

iwallet --account admin --amount_limit "ram:100000" publish contract/lucky_bet.js contract/lucky_bet.js.abi

Sending transaction...
Transaction has been sent.
The transaction hash is: 2xC6ziTqXaat7dsrya9pHog6NEEAMgBMKWcMv5YNDEpa
Checking transaction receipt...
SUCCESS!
The contract id is: Contract2xC6ziTqXaat7dsrya9pHog6NEEAMgBMKWcMv5YNDEpa

ContractXXX of the last line in output is the contract name, which would be needed if one wants to call this new contract later.

Transfer IOST Tokens

Transfer 100 IOST tokens to user test1 by user test0:

iwallet transfer test1 100 --account test0

Get Reward

Check reward for more information about the reward model.

Redeem Contribution Value

Redeem all contribution value to IOST tokens:

iwallet sys producer-redeem --account test0

Redeem 100 contribution value to 100 IOST tokens:

iwallet sys producer-redeem 100 --account test0

Get Producer Voting Reward

If user test0 is a producer:

iwallet sys producer-withdraw --account test0

Get Voter Voting Reward

If user test0 is a voter:

iwallet sys voter-withdraw --account test0

Cold Wallet

Cold wallet, aka cold storage or offline wallet, refers to keeping a reserve completely offline. We would introduce a basic scene to show how to use iwallet as cold wallet.

The following action is a simple transfer from user test0 to user test1:

iwallet transfer test1 1 --account test0

Sending transaction...
Transaction has been sent.
The transaction hash is: HK7Ue95vah88PJq8wBhc6mwazgBezV2p6rMRFGFmcyjG
Checking transaction receipt...
SUCCESS!

Actually there are 2 steps before sending transaction: initialize transaction and sign it with private key of account given by flag --account. Let's separate the sign step and do it only on a computer that is always offline.

Assume there is an offline computer A that stores the private key of user test0 (suggest to encrypt the private key also) and an online computer B that stores another user test_pub as publisher for sending transaction onto blockchain. And we could do the same transfer in following steps:

Save Transaction

Generate the transfer transaction with reasonable execute time (like delay 600 seconds in following example) in whether computer A or B:

iwallet transfer test1 1 --account test0 --tx_time_delay 600 --output tx.json

Transaction:
{

}
Successfully saved transaction request as json file: tx.json

Sign Transaction

Sign the transaction contained in file tx.json with key file ~/.iwallet/test0.json in offline computer A:

iwallet sign tx.json ~/.iwallet/test0.json sig.json

Signature:
{
    "algorithm": "ED25519",

}
Successfully saved signature as: sig.json

Send Transaction

Send the transaction contained in file tx.json with signature file sig.json in online computer B:

iwallet send tx.json --signature_files sig.json --account test_pub

Permission setting example

Seperate wallet account and operation account

Use the account authority management to realize the function of triggering the voting reward to receive the account and receiving the bonus account separation function.

  • Two accounts a and b, a is the receiving voting income account, b is the trigger to receive the income account
  • First add the operate permission to the account
    • iwallet sys addperm operate 100 --account a_name
  • a account to add b account permission reference to the permission operate
    • iwallet sys assignperm operate b_name@active 100 --account a_name
  • Use b account to trigger the voting income of a account
    • If the a account is a node：iwallet sys producer-withdraw --target a_name --account b_name
    • If the a account is a voter：iwallet sys voter-withdraw --target a_name --account b_name

Change keypairs

The following command changes keypair of an account.

# changing owner key of account testacc from 78N7.... to BBwM...
# 100 is the default threshold of permission, we must use this same value here
# You can also change active keypair using similar command
# Step 1: add a new permission key
iwallet -a testacc call auth.iost assignPermission '["testacc","owner","BBwMULYkv1JXh9jnN6ECbED5QcvjxnLxy2QHjy3xxEEn",100]' --signers testacc@owner 
# Step 2: remove the old permission key 
iwallet -a testacc call auth.iost revokePermission '["testacc","owner","78N7oANHbBrAxG2Ru7yfzSv73o1z4K4EDskxFTfDkspo"]' --signers testacc@owner
# Now since the owner key of testacc is changed, the ~/.iwallet/testacc.json is outdated. You have to edit this file to use the account later.

Multiple Signature

You can use the powerful IOST account/permission system to do multisig. Only when multiple users' permission are obtained can a tx be executed.
Multisig is complex, you should have a good understanding of IOST account/permission system before using it. Here is a full demo of this feature.
