# 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.
HUP signal also reconfigures logging level if it's changed in the
configuration file (LogLevel option in ApplicationConfig).
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/reset
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.
NeoGo allows to reset the node state to a particular point. It is possible for
those nodes that do store complete chain state or for nodes with `RemoveUntraceableBlocks`
setting on that are not yet reached `MaxTraceableBlocks` number of blocks. Use
`db reset` command with the target block specified to roll back all the changes
made since the target block (not including changes made by the specified block
acceptance). The set of changes to be removed includes blocks, transactions,
execution results, contract storage changes, MPT-related auxiliary data and NEP
transfers data. Some stale MPT nodes may be left in storage after reset.
Once DB reset is finished, the node can be started in a regular manner.
## 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.
All commands (with few exceptions) accepting wallet via `-w` (or `--wallet`)
parameter (and providing an interactive password prompt if needed) can also
alternatively work with YAML configuration file passed via the
`--wallet-config` parameter. This file uses a format similar to node's
wallet-related configuration sections:
```
Path: "/path/to/wallet.json"
Password: "pass"
```
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).
#### Strip keys from accounts
`wallet strip-keys` allows you to remove private keys from the wallet, but let
it be used for other purposes (like creating transactions for subsequent
offline signing). Use with care, don't lose your keys with it.
### 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

#### Candidate/voting data
`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
```
### Transaction signing
`wallet sign` command allows to sign arbitary transactions stored in JSON
format (also known as ContractParametersContext). Usually it's used in one of
the two cases: multisignature signing (when you don't have all keys for an
account and need to share the context with others until enough signatures
collected) or offline signing (when the node with a key is completely offline
and can't interact with the RPC node directly).
#### Multisignature collection
For example, you have a four-node default network setup and want to set some
key for the oracle role, you create transaction with:
```
$ neo-go contract invokefunction -w .docker/wallets/wallet1.json --out some.part.json -a NVTiAjNgagDkTr5HTzDmQP9kPwPHN5BgVq -r http://localhost:30333 0x49cf4e5378ffcd4dec034fd98a174c5491e395e2 designateAsRole 8 \[ 02b3622bf4017bdfe317c58aed5f4c753f206b7db896046fa7d774bbc4bf7f8dc2 \] -- NVTiAjNgagDkTr5HTzDmQP9kPwPHN5BgVq:CalledByEntry
```
And then sign it with two more keys:
```
$ neo-go wallet sign -w .docker/wallets/wallet2.json --in some.part.json --out some.part.json -a NVTiAjNgagDkTr5HTzDmQP9kPwPHN5BgVq
$ neo-go wallet sign -w .docker/wallets/wallet3.json --in some.part.json -r http://localhost:30333 -a NVTiAjNgagDkTr5HTzDmQP9kPwPHN5BgVq
```
Notice that the last command sends the transaction (which has a complete set
of singatures for 3/4 multisignature account by that time) to the network.
#### Offline signing
You want to do a transfer from a single-key account, but the key is on a
different (offline) machine. Create a stripped wallet first on the key-holding
machine:
```
$ cp wallet.json wallet.stripped.json # don't lose the original wallet
$ neo-go wallet strip-keys --wallet wallet.stripped.json
```
This wallet has no keys inside (but has appropriate scripts/addresses), so it
can be safely shared with anyone or transferred to network-enabled machine
where you then can create a transfer transaction:
```
$ neo-go wallet nep17 transfer --rpc-endpoint http://localhost:20332 \
--wallet wallet.stripped.json --from NjEQfanGEXihz85eTnacQuhqhNnA6LxpLp \
--to Nj91C8TxQSxW1jCE1ytFre6mg5qxTypg1Y --token NEO --amount 1 --out context.json
```
`context.json` can now be transferred to the machine with the `wallet.json`
containing proper keys and signed:
```
$ neo-go wallet sign --wallet wallet.json \
-address NjEQfanGEXihz85eTnacQuhqhNnA6LxpLp --in context.json --out context.json
```
Now `context.json` contains a transaction with a complete set of signatures
(just one in this case, but of course you can do multisignature collection as
well). It can be transferred to network-enabled machine again and the
transaction can be sent to the network:
```
$ neo-go util sendtx --rpc-endpoint http://localhost:20332 context.json
```
### 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 that are owned by all accounts
stored in the given wallet. You can specify a particular address with `-a`
flag and/or select token with `--token` flag (token hash, address, name or
symbol can be used as a 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 get data for a particular NFT:
```
./bin/neo-go wallet nep11 balance -w /etc/neo-go/wallet.json --token 67ecb7766dba4acf7c877392207984d1b4d15731 --id 7e244ffd6aa85fb1579d2ed22e9b761ab62e3486 -r http://localhost:20332
```
By default, no token ID specified, i.e all NFTs returned by the server are listed.
#### 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
```
## Utility commands
### Value conversion
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

### Transaction dumps/test invocations
If you have a transaction signing context saved in a file (and many commands
like `wallet nep17 transfer` or `contract invokefunction` can give you one
with the `--out` parameter) you may want to check the contents before signing
it. This can be done with the `util txdump` command:
```
$ ./bin/neo-go util txdump -r http://localhost:30333 some.part.json

```
It always outputs the basic data and also can perform test-invocation if an
RPC endpoint is given to it.
### Sending signed transaction to the network
If you have a completely finished (with all signatures collected) transaction
signing context saved in a file you can send it to the network (without any
wallet) using `util sendtx` command:
```
$ ./bin/neo-go util sendtx -r http://localhost:30333 some.part.json
```
This is useful in offline signing scenario, where the signing party doesn't
have any network access, so you can make a signature there, transfer the file
to another machine that has network access and then push the transaction out
to the network.
## 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).
