Server commands

To run a command that requires a connection to an online Oasis node (i.e. the server), you need to either:

  • change the working directory to where the internal Oasis node UNIX socket is located (e.g. /serverdir/node/) before executing the command, or
  • pass the -a $ADDR flag where ADDR represents the path to the internal Oasis node UNIX socket prefixed with unix: (e.g.unix:/serverdir/node/internal.sock).

Here are some examples of Oasis Node CLI commands that need a connection to an online Oasis node:

  • oasis-node stake info: Shows general staking information.
  • oasis-node stake list: Lists all accounts with positive balance.
  • oasis-node stake account info: Shows detailed information for an account.
  • oasis-node consensus submit_tx: Submits a pre-generated transaction to the network.

Local commands

The following commands are intended to be run on your local machine and only need access to the network's current genesis file and your signer's private key:

  • oasis-node stake account gen_transfer
  • oasis-node stake account gen_escrow
  • oasis-node stake account gen_reclaim_escrow
  • oasis-node stake account gen_amend_commission_schedule

We strongly suggest that you do not use any entity/staking account that is generated with the file-based signer on the Mainnet.

In case you need to use the file-based signer, make sure you only use it on an offline/air-gapped machine. Gaining access to your entity's/staking account's private key can compromise your tokens.

JSON pretty-printing

We will pipe the output of commands that return JSON through Python's json.tool module to pretty-print it.


Be aware that jq, the popular JSON CLI tool, converts all numbers to IEEE 754 64-bit values which can result in silent loss of precision and/or other changes.

Hence, we recommend avoiding its usage until this issue is resolved.

Common CLI Flags

Base Flags

All commands for generating and signing transactions need the following base flags set:

  • --genesis.file: Path to the genesis file, e.g. /localhostdir/genesis.json.

For convenience, set the GENESIS_FILE environment value to its value, e.g.:

  • --signer.dir: Path to entity's artifacts directory, e.g. entity-$LEDGER_INDEX

    or /localhostdir/entity/

Signer Flags

Currently, we provide two options for signing transactions:

  • Ledger-based signer.

    You will need to set it up as described in our Oasis Core Ledger docs.

  • File-based signer.

    You will need to create your Entity as described in Running a Node on the Network docs and set the following flags:

    • --signer.backend file: Specifies use of the file signer.

Storing Base and Signer flags in an Environment Variable

To make the transaction commands shorter and avoid typing errors, one can create an environment variable, e.g. TX_FLAGS, with all the Base Flags and Signer Flags configured for his particular set up.

For example, one could set TX_FLAGS for a Ledger device like below (make sure all LEDGER_* environment variables are set appropriately):

TX_FLAGS=(--genesis.file "$GENESIS_FILE"
--signer.dir /localhostdir/entity
--signer.backend plugin ledger
--signer.plugin.path "$LEDGER_SIGNER_PATH"

Or, one could set TX_FLAGS like below to use a file signer:

TX_FLAGS=(--genesis.file "$GENESIS_FILE"
--signer.backend file
--signer.dir /localhostdir/entity/

Common Transaction Flags

When generating a transaction, one needs to set the following transaction flags as appropriate for a given transaction:

  • --stake.amount: Amount of base units to transfer, escrow, burn, etc.
  • --transaction.file: Path to the file where to store the generated transaction.
  • --transaction.nonce: Incremental number that must be unique for each account's transaction. To get your current account's nonce, see Checking Your Account nonce doc.
  • --transaction.fee.gas: Maximum amount of gas (in gas units) a transaction can spend.

Gas costs for different staking transactions are specified by the staking.params.gas_costs consensus parameter.

To obtain its value from the genesis file, run:

  cat $GENESIS_FILE | \
python3 -c 'import sys, json; \
print(json.dumps(json.load(sys.stdin)["staking"]["params"]["gas_costs"], indent=4))'
  • --transaction.fee.amount: Amount of base units we will pay as a fee for a transaction.

Note that specifying a transaction's fee amount (via --transaction.fee.amount) and maximum gas amount (via --transaction.fee.gas) implicitly defines the gas price (in base units):

gas_price = fee_amount / gas_amount

Gas price tells how much base units we are willing to pay for one gas unit.

Consensus validators can configure their own minimum gas price (via consensus.tendermint.min_gas_price configuration flag) and will refuse to process transactions that have their gas price set below their minimum gas price.


Currently, there is no mechanism to discover what minimum gas prices are used by validators.
