See neo-project/neo#2390. Can't see it there? No wonder, that's why we have this bug for a year and a half. Not critical, we don't care about versions, but _very_ annoying.

# NeoGo CLI interface
|
|
|
|
NeoGo CLI provides all functionality from one binary. It's used to run
|
|
a node, create/compile/deploy/invoke/debug smart contracts, run vm and operate
|
|
with a wallet. Standard setup assumes that you run a node as a
|
|
separate process, and it doesn't provide any CLI of its own. Instead, it just
|
|
makes RPC interface available for you. To perform any actions, you invoke NeoGo
|
|
as a client that connects to this RPC node and does things you want it to do
|
|
(like transferring some NEP-17 asset).
|
|
|
|
All CLI commands have corresponding help messages, use `--help` option to get
|
|
them, for example:
|
|
```
|
|
./bin/neo-go db --help
|
|
```
|
|
|
|
## Running node
|
|
|
|
Use `node` command to run a NeoGo node, it will be configured using a YAML
|
|
file that contains network parameters as well as node settings.
|
|
|
|
### Configuration
|
|
|
|
All config files are located in `./config` and they are differentiated according to the network type:
|
|
- `protocol.mainnet.yml` belongs to `--mainnet` network mode (`-m` short option)
|
|
- `protocol.privnet.yml` belongs to `--privnet` network mode (`-p` short
|
|
option) and is used by default
|
|
- `protocol.testnet.yml` belongs to `--testnet` network mode (`-t` short option)
|
|
- `protocol.unit_testnet.yml` is used by unit tests
|
|
|
|
If you want to use some non-default configuration directory path, specify
|
|
`--config-path` flag:
|
|
|
|
`./bin/neo-go node --config-path /user/yourConfigPath`
|
|
|
|
The file loaded is chosen automatically depending on network mode flag.
|
|
|
|
Refer to the [node configuration documentation](./node-configuration.md) for
|
|
detailed configuration file description.
|
|
|
|
### Starting a node
|
|
|
|
To start Neo node on private network, use:
|
|
|
|
```
|
|
./bin/neo-go node
|
|
```
|
|
|
|
Or specify a different network with an appropriate flag like this:
|
|
|
|
```
|
|
./bin/neo-go node --mainnet
|
|
```
|
|
|
|
By default, the node will run in the foreground using current standard output for
|
|
logging.
|
|
|
|
|
|
### Node synchronization
|
|
|
|
Most of the services (state validation, oracle, consensus and RPC if
|
|
configured with `StartWhenSynchronized` option) are only started after the
|
|
node is completely synchronizaed because running them before that is either
|
|
pointless or even dangerous. The node considers itself to be fully
|
|
synchronized with the network if it has more than `MinPeers` neighbours and if
|
|
at least 2/3 of them are known to have a height less than or equal to the
|
|
current height of the node.
|
|
|
|
### Restarting node services
|
|
|
|
On Unix-like platforms HUP, USR1 and USR2 signals can be used to control node
|
|
services. Upon receiving any of these signals node rereads the configuration
|
|
file, checks for its compatibility (ProtocolConfiguration can't be changed and
|
|
ApplicationConfiguration can only be changed for services) and then
|
|
stops/starts services according to the old and new configurations. Services
|
|
are broadly split into three main categories:
|
|
* client-oriented
|
|
These provide some service to clients: RPC, Pprof and Prometheus
|
|
servers. They're controlled with the HUP signal.
|
|
* network-oriented
|
|
These provide some service to the network: Oracle, State validation and P2P
|
|
Notary. They're controlled with the USR1 signal.
|
|
* consensus
|
|
That's dBFT, it's a special one and it's controlled with USR2.
|
|
|
|
Typical scenarios when this can be useful (without full node restart):
|
|
* enabling some service
|
|
* changing RPC configuration
|
|
* updating TLS certificates for the RPC server
|
|
* resolving operational issues
|
|
|
|
### DB import/exports
|
|
|
|
Node operates using some database as a backend to store blockchain data. NeoGo
|
|
allows to dump chain into a file from the database (when node is stopped) or to
|
|
import blocks from a file into the database (also when node is stopped). Use
|
|
`db` command for that.
|
|
|
|
## Smart contracts
|
|
|
|
Use `contract` command to create/compile/deploy/invoke/debug smart contracts,
|
|
see [compiler documentation](compiler.md).
|
|
|
|
## Wallet operations
|
|
|
|
`wallet` command provides interface for all operations requiring a wallet
|
|
(except contract deployment and invocations that are done via `contract
|
|
deploy` and `contract invokefunction`). Wallet management (creating wallet,
|
|
adding addresses/keys to it) is available there as well as wallet-related
|
|
functions like NEP-17 transfers, NEO votes, multi-signature signing and other
|
|
things. For all commands requiring read-only wallet (like `dump-keys`) a
|
|
special `-` path can be used to read the wallet from the standard input.
|
|
|
|
### Wallet management
|
|
|
|
#### Create wallet
|
|
|
|
Use `wallet init` command to create a new wallet:
|
|
```
|
|
./bin/neo-go wallet init -w wallet.nep6
|
|
|
|
{
|
|
"version": "1.0",
|
|
"accounts": [],
|
|
"scrypt": {
|
|
"n": 16384,
|
|
"r": 8,
|
|
"p": 8
|
|
},
|
|
"extra": {
|
|
"Tokens": null
|
|
}
|
|
}
|
|
|
|
wallet successfully created, file location is wallet.nep6
|
|
```
|
|
|
|
where "wallet.nep6" is a wallet file name. This wallet will be empty. To
|
|
generate a new key pair and add an account for it, use `-a` option:
|
|
```
|
|
./bin/neo-go wallet init -w wallet.nep6 -a
|
|
Enter the name of the account > Name
|
|
Enter passphrase >
|
|
Confirm passphrase >
|
|
|
|
{
|
|
"version": "1.0",
|
|
"accounts": [
|
|
{
|
|
"address": "NMe64G6j6nkPZby26JAgpaCNrn1Ee4wW6E",
|
|
"key": "6PYL2UrC11nWFJWSLiqsPKCNm9u4zr4ttX1ZbV9f2fLDqXsePioVxEsYdg",
|
|
"label": "Name",
|
|
"contract": {
|
|
"script": "DCEDzs1j19gSDDsZTDsogN1Kr+FHXFfkDIUoctcwVhUlgUBBdHR2qg==",
|
|
"parameters": [
|
|
{
|
|
"name": "parameter0",
|
|
"type": "Signature"
|
|
}
|
|
],
|
|
"deployed": false
|
|
},
|
|
"lock": false,
|
|
"isDefault": false
|
|
}
|
|
],
|
|
"scrypt": {
|
|
"n": 16384,
|
|
"r": 8,
|
|
"p": 8
|
|
},
|
|
"extra": {
|
|
"Tokens": null
|
|
}
|
|
}
|
|
|
|
wallet successfully created, file location is wallet.nep6
|
|
```
|
|
|
|
or use `wallet create` command to create a new account in an existing wallet:
|
|
```
|
|
./bin/neo-go wallet create -w wallet.nep6
|
|
Enter the name of the account > Joe Random
|
|
Enter passphrase >
|
|
Confirm passphrase >
|
|
```
|
|
|
|
#### Convert Neo Legacy wallets to Neo N3
|
|
|
|
Use `wallet convert` to update addresses in NEP-6 wallets used with Neo
|
|
Legacy. New wallet is specified in `-o` option, it will have the same keys
|
|
with Neo N3 addresses (notice that it doesn't do anything to your assets, it
|
|
just allows to reuse the old key on N3 network).
|
|
```
|
|
./bin/neo-go wallet convert -w old.nep6 -o new.nep6
|
|
```
|
|
|
|
#### Check wallet contents
|
|
`wallet dump` can be used to see wallet contents in a more user-friendly way,
|
|
its output is the same NEP-6 JSON, but better formatted. You can also decrypt
|
|
keys at the same time with `-d` option (you'll be prompted for password):
|
|
```
|
|
./bin/neo-go wallet dump -w wallet.nep6 -d
|
|
Enter wallet password >
|
|
|
|
{
|
|
"version": "1.0",
|
|
"accounts": [
|
|
{
|
|
"address": "NMe64G6j6nkPZby26JAgpaCNrn1Ee4wW6E",
|
|
"key": "6PYL2UrC11nWFJWSLiqsPKCNm9u4zr4ttX1ZbV9f2fLDqXsePioVxEsYdg",
|
|
"label": "Name",
|
|
"contract": {
|
|
"script": "DCEDzs1j19gSDDsZTDsogN1Kr+FHXFfkDIUoctcwVhUlgUBBdHR2qg==",
|
|
"parameters": [
|
|
{
|
|
"name": "parameter0",
|
|
"type": "Signature"
|
|
}
|
|
],
|
|
"deployed": false
|
|
},
|
|
"lock": false,
|
|
"isDefault": false
|
|
}
|
|
],
|
|
"scrypt": {
|
|
"n": 16384,
|
|
"r": 8,
|
|
"p": 8
|
|
},
|
|
"extra": {
|
|
"Tokens": null
|
|
}
|
|
}
|
|
```
|
|
|
|
You can also get public keys for addresses stored in your wallet with `wallet
|
|
dump-keys` command:
|
|
```
|
|
./bin/neo-go wallet dump-keys -w wallet.nep6
|
|
NMe64G6j6nkPZby26JAgpaCNrn1Ee4wW6E (simple signature contract):
|
|
03cecd63d7d8120c3b194c3b2880dd4aafe1475c57e40c852872d7305615258140
|
|
```
|
|
|
|
#### Private key export
|
|
`wallet export` allows you to export a private key in NEP-2 encrypted or WIF
|
|
(unencrypted) form (`-d` flag).
|
|
```
|
|
$ ./bin/neo-go wallet export -w wallet.nep6 -d NMe64G6j6nkPZby26JAgpaCNrn1Ee4wW6E
|
|
Enter password >
|
|
KyswN8r48dhsvyQJVy97RWnZmKgYLrXv9mCL81Kb4vAagZiCsePv
|
|
```
|
|
|
|
#### Private key import
|
|
You can import NEP-2 or WIF private key along with verification contract (if
|
|
it's non-standard):
|
|
```
|
|
./bin/neo-go wallet import --wif KwYgW8gcxj1JWJXhPSu4Fqwzfhp5Yfi42mdYmMa4XqK7NJxXUSK7 -w wallet.nep6
|
|
Provided WIF was unencrypted. Wallet can contain only encrypted keys.
|
|
Enter the name of the account > New Account
|
|
Enter passphrase >
|
|
Confirm passphrase >
|
|
```
|
|
|
|
#### Special accounts
|
|
Multisignature accounts can be imported with `wallet import-multisig`, you'll
|
|
need all public keys and one private key to do that. Then, you could sign
|
|
transactions for this multisignature account with the imported key.
|
|
|
|
`wallet import-deployed` can be used to create wallet accounts for deployed
|
|
contracts. They also can have WIF keys associated with them (in case your
|
|
contract's `verify` method needs some signature).
|
|
|
|
### Neo voting
|
|
`wallet candidate` provides commands to register or unregister a committee
|
|
(and therefore validator) candidate key:
|
|
```
|
|
./bin/neo-go wallet candidate register -a NMe64G6j6nkPZby26JAgpaCNrn1Ee4wW6E -w wallet.json -r http://localhost:20332
|
|
```
|
|
|
|
You can also vote for candidates if you own NEO:
|
|
```
|
|
./bin/neo-go wallet candidate vote -a NMe64G6j6nkPZby26JAgpaCNrn1Ee4wW6E -w wallet.json -r http://localhost:20332 -c 03cecd63d7d8120c3b194c3b2880dd4aafe1475c57e40c852872d7305615258140
|
|
```
|
|
|
|
Do not provide candidate argument to perform unvoting:
|
|
```
|
|
./bin/neo-go wallet candidate vote -a NMe64G6j6nkPZby26JAgpaCNrn1Ee4wW6E -w wallet.json -r http://localhost:20332
|
|
```
|
|
|
|
### Getting data from chain
|
|
|
|
#### Node height/validated height
|
|
`query height` returns the latest block and validated state height:
|
|
```
|
|
$ ./bin/neo-go query height -r http://localhost:20332
|
|
Latest block: 11926
|
|
Validated state: 11926
|
|
```
|
|
|
|
#### Transaction status
|
|
`query tx` provides convenient wrapper over RPC calls to query transaction status.
|
|
```
|
|
./bin/neo-go query tx --rpc-endpoint http://localhost:20332 aaf87628851e0c03ee086ff88596bc24de87082e9e5c73d75bb1c740d1d68088
|
|
Hash: aaf87628851e0c03ee086ff88596bc24de87082e9e5c73d75bb1c740d1d68088
|
|
OnChain: true
|
|
BlockHash: fabcd46e93b8f4e1bc5689e3e0cc59704320494f7a0265b91ae78b4d747ee93b
|
|
Success: true
|
|
```
|
|
`OnChain` is true if the transaction has been included in the block; and `Success` is true
|
|
if it has been executed successfully.
|
|
|
|
#### Committee members
|
|
`query commitee` returns a list of current committee members:
|
|
```
|
|
$ ./bin/neo-go query committee -r http://localhost:20332
|
|

`query candidates` returns all current candidates, number of votes for them
|
|
and their committee/consensus status:
|
|
```
|
|
$ ./bin/neo-go query candidates -r http://localhost:20332
|

#### Voter data
|
|
`query voter` returns additional data about NEO holder: the amount of NEO he has,
|
|
the candidate it voted for (if any) and the block number of the last transactions
|
|
involving NEO on this account:
|
|
```
|
|
$ ./bin/neo-go query voter -r http://localhost:20332 Nj91C8TxQSxW1jCE1ytFre6mg5qxTypg1Y
|
|
Voted: 0214baf0ceea3a66f17e7e1e839ea25fd8bed6cd82e6bb6e68250189065f44ff01 (Nj91C8TxQSxW1jCE1ytFre6mg5qxTypg1Y)
|
|
Amount : 2000000
|
|
Block: 3970

### NEP-17 token functions
|
|
|
|
`wallet nep17` contains a set of commands to use for NEP-17 tokens.
|
|
|
|
#### Token metadata
|
|
|
|
NEP-17 commands are designed to work with any NEP-17 tokens, but NeoGo needs
|
|
some metadata for these tokens to function properly. Native NEO or GAS are
|
|
known to NeoGo by default, but other tokens are not. NeoGo can get this
|
|
metadata from the specified RPC server, but that's an additional request to
|
|
make. So, if you care about command processing delay, you can import token
|
|
metadata into the wallet with `wallet nep17 import` command. It'll be stored
|
|
in the `extra` section of the wallet.
|
|
```
|
|
./bin/neo-go wallet nep17 import -w wallet.nep6 -r http://localhost:20332 -t abcdefc189f30098b0ba6a2eb90b3a925800ffff
|
|
```
|
|
|
|
You can later see what token data you have in your wallet with `wallet nep17
|
|
info` command and remove tokens you don't need with `wallet nep17 remove`.
|
|
|
|
#### Balance
|
|
Getting balance is easy:
|
|
```
|
|
./bin/neo-go wallet nep17 balance -w /etc/neo-go/wallet.json -r http://localhost:20332
|
|
```
|
|
|
|
By default, you'll get data for all tokens for the default wallet's
|
|
address. You can select non-default address with `-a` flag and/or select token
|
|
with `--token` flag (token hash or name can be used as parameter).
|
|
|
|
#### Transfers
|
|
|
|
`wallet nep17 transfer` creates a token transfer transaction and pushes it to
|
|
the RPC server (or saves to file if it needs to be signed by multiple
|
|
parties). For example, transferring 100 GAS looks like this:
|
|
|
|
```
|
|
./bin/neo-go wallet nep17 transfer -w wallet.nep6 -r http://localhost:20332 --to NjEQfanGEXihz85eTnacQuhqhNnA6LxpLp --from NMe64G6j6nkPZby26JAgpaCNrn1Ee4wW6E --token GAS --amount 100
|
|
```
|
|
|
|
You can omit `--from` parameter (default wallet's address will be used in this
|
|
case), you can add `--gas` for extra network fee (raising priority of your
|
|
transaction). And you can save the transaction to a file with `--out` instead of
|
|
sending it to the network if it needs to be signed by multiple parties.
|
|
|
|
To add optional `data` transfer parameter, specify `data` positional argument
|
|
after all required flags. Refer to `wallet nep17 transfer --help` command
|
|
description for details.
|
|
|
|
One `transfer` invocation creates one transaction. In case you need to do
|
|
many transfers, you can save on network fees by doing multiple token moves with
|
|
one transaction by using `wallet nep17 multitransfer` command. It can transfer
|
|
things from one account to many, its syntax differs from `transfer` in that
|
|
you don't have `--token`, `--to` and `--amount` options, but instead you can
|
|
specify multiple "token:addr:amount" sets after all other options. The same
|
|
transfer as above can be done with `multitransfer` by doing this:
|
|
```
|
|
./bin/neo-go wallet nep17 multitransfer -w wallet.nep6 -r http://localhost:20332 --from NMe64G6j6nkPZby26JAgpaCNrn1Ee4wW6E GAS:NjEQfanGEXihz85eTnacQuhqhNnA6LxpLp:100
|
|
```
|
|
|
|
#### GAS claims
|
|
|
|
While Neo N3 doesn't have any notion of "claim transaction" and has GAS
|
|
automatically distributed with every NEO transfer for NEO owners, you still
|
|
won't get GAS if you don't do any actions. So the old `wallet claim` command
|
|
was updated to be an easier way to do NEO "flipping" when you send a
|
|
transaction that transfers all of your NEO to yourself thereby triggering GAS
|
|
distribution.
|
|
|
|
### NEP-11 token functions
|
|
|
|
`wallet nep11` contains a set of commands to use for NEP-11 tokens. Token
|
|
metadata related commands (`info`, `import` and `remove`) works the same way as
|
|
for NEP-17 tokens. The syntax of other commands is very similar to NEP-17
|
|
commands with the following adjustments.
|
|
|
|
#### Balance
|
|
|
|
Specify token ID via `--id` flag to call divisible NEP-11 `balanceOf` method:
|
|
|
|
```
|
|
./bin/neo-go wallet nep11 balance -w /etc/neo-go/wallet.json --token 67ecb7766dba4acf7c877392207984d1b4d15731 --id R5OREI5BU+Uyd23/MuV/xzI3F+Q= -r http://localhost:20332
|
|
```
|
|
|
|
By default, no token ID specified, i.e. common `balanceOf` method is called.
|
|
|
|
#### Transfers
|
|
|
|
Specify token ID via `--id` flag to transfer NEP-11 token. Specify the amount to
|
|
transfer divisible NEP-11 token:
|
|
|
|
```
|
|
./bin/neo-go wallet nep11 transfer -w wallet.nep6 -r http://localhost:20332 --to NjEQfanGEXihz85eTnacQuhqhNnA6LxpLp --from NMe64G6j6nkPZby26JAgpaCNrn1Ee4wW6E --token 67ecb7766dba4acf7c877392207984d1b4d15731 --id R5OREI5BU+Uyd23/MuV/xzI3F+Q= --amount 5
|
|
```
|
|
|
|
By default, no amount is specified, i.e. the whole token is transferred for
|
|
non-divisible tokens and 100% of the token is transferred if there is only one
|
|
owner of this token for divisible tokens.
|
|
|
|
Unlike NEP-17 tokens functionality, `multitransfer` command is currently not
|
|
supported on NEP-11 tokens.
|
|
|
|
#### Tokens Of
|
|
|
|
To print token IDs owned by the specified owner, use `tokensOf` command with
|
|
`--token` and `--address` flags:
|
|
|
|
```
|
|
./bin/neo-go wallet nep11 tokensOf -r http://localhost:20332 --token 67ecb7766dba4acf7c877392207984d1b4d15731 --address NbrUYaZgyhSkNoRo9ugRyEMdUZxrhkNaWB
|
|
```
|
|
|
|
#### Owner Of
|
|
|
|
For non-divisible NEP-11 tokens only. To print owner of non-divisible NEP-11 token
|
|
use `ownerOf` method, specify token hash via `--token` flag and token ID via
|
|
`--id` flag:
|
|
|
|
```
|
|
./bin/neo-go wallet nep11 ownerOf -r http://localhost:20332 --token 67ecb7766dba4acf7c877392207984d1b4d15731 --id R5OREI5BU+Uyd23/MuV/xzI3F+Q=
|
|
```
|
|
|
|
#### Optional methods
|
|
|
|
##### 1. Properties
|
|
|
|
If NEP-11 token supports optional `properties` method, specify token hash via
|
|
`--token` flag and token ID via `--id` flag to print properties:
|
|
|
|
```
|
|
./bin/neo-go wallet nep11 properties -r http://localhost:20332 --token 67ecb7766dba4acf7c877392207984d1b4d15731 --id 7V5gjT2WwjP3pBCQMKGMfyZsp/w=
|
|
```
|
|
|
|
##### 2. Tokens
|
|
|
|
If NEP-11 token supports optional `tokens` method, specify token hash via
|
|
`--token` flag to print the list of token IDs minted by the specified NFT:
|
|
|
|
```
|
|
./bin/neo-go wallet nep11 tokens -r http://localhost:20332 --token 67ecb7766dba4acf7c877392207984d1b4d15731
|
|
```
|
|
|
|
## Conversion utility
|
|
|
|
NeoGo provides conversion utility command to reverse data, convert script
|
|
hashes to/from address, convert public keys to hashes/addresses, convert data to/from hexadecimal or base64
|
|
representation. All of this is done by a single `util convert` command like
|
|
this:
|
|
```
|
|
$ ./bin/neo-go util convert deee79c189f30098b0ba6a2eb90b3a9258a6c7ff

## VM CLI
|
|
There is a VM CLI that you can use to load/analyze/run/step through some code:
|
|
|
|
```
|
|
./bin/neo-go vm
|
|
```
|
|
|
|
Some basic commands available there:
|
|
|
|
- `loadgo` -- loads smart contract `NEO-GO-VM > loadgo TestContract/main.go`
|
|
- `ops` -- show the opcodes of currently loaded contract
|
|
- `run` -- executes currently loaded contract
|
|
|
|
Use `help` command to get more detailed information on all options and
|
|
particular commands. Note that this VM is completely disconnected from the
|
|
blockchain, so you won't have all interop functionality available for smart
|
|
contracts (use test invocations via RPC for that).
