Overview
This section will guide you through how you can run your own validator. Validator operations may be done via the story
consensus client.
The below operations do not require running a node! However, if you would like to participate in staking rewards, you must run a validator node.
Before proceeding, it is important to familiarize yourself with the difference between a delegator and a validator:
- A validator is a full node that participates in consensus whose signed key resides in the
priv_validator_key.json
file under yourstory
data directory. To print out your validator key details you may refer to the validator key export section - A delegator refers to an account operator that holds
IP
and wishes to participate in consensus rewards but without needing to run a validator themselves.
In the same folder as where your story
binary resides, add a .env
file with a PRIVATE_KEY
whose account has IP
funded. We recommend using your delegator account for all below operations.
You may also issue transactions as the validator itself. To get the EVM private key corresponding to your validator, please refer to the Validator Key Export section.
The .env
file should look like the following (make sure not to add a 0x prefix):
With this, you are all set to perform different validator operations! Below, we will guide you through all of those supported via the CLI:
Validator Key Export
By default, when you run ./story init
a validator key is created for you. To view your validator key, run the following command:
This will print out your validator public key file in compressed and uncompressed formats. By default, we use the hex-encoded compressed key for public identification.
Available Flags:
--export-evm-key
: (string) Exports the derived EVM private key of your validator into the default data config directory--export-evm-key-path
: (string) Specifies a different download location for the derived EVM private key of your validator--keyfile
: (string) Path to the Tendermint key file (default “/home/ubuntu/.story/story/config/priv_validator_key.json”)
If you would like to issue transactions as your validator, and not as a
delegator, you may export the key to your .env
file and ensure it has IP
sent to it, e.g. via ./story validator export --export-evm-key --evm-key-path .env
Validator Creation
To create a new validator, run the following command:
This will create the validator corresponding to your validator key saved in priv_validator_key.json
, providing the validator with {$AMOUNT_TO_STAKE_IN_WEI}
IP to self-stake.
To participate in consensus, at least 1024 IP must be staked (equivalent to
1024000000000000000000 wei
)!
Below is a list of optional flags to further customize your validator setup:
Available Flags:
--stake
: Sets the amount the validator will self-delegate in wei (default is1024000000000000000000
wei).--moniker
: Defines a custom name for the validator, visible to users on the network.--chain-id
: Specifies the Chain ID for the transaction. By default, this is set to1516
.--commission-rate
: Sets the validator’s commission rate in bips (1% = 100 bips). For instance,1000
represents a 10% commission (default is1000
).--explorer
: Specifies the URL of the blockchain explorer (default: https://www.storyscan.io).--keyfile
: Points to the path of the Tendermint key file (default:$HOME/.story/story/config/priv_validator_key.json
).--max-commission-change-rate
: Sets the maximum rate at which the validator’s commission can change, in bips. For example,100
represents a maximum change of 1% (default is1000
).--max-commission-rate
: Defines the maximum commission rate the validator can charge, in bips. For instance,5000
allows a 50% maximum rate (default is5000
).--private-key
: Uses a specified private key for signing the transaction. If not set, the key inpriv_validator_key.json
will be used.--rpc
: Sets the RPC URL to connect to the network (default: https://mainnet.storyrpc.io).--unlocked
: Determines if unlocked token staking is supported (true
for unlocked staking,false
for locked staking). By default, this is set totrue
.--story-api
: Prevent potential fund losses. By default, you should sethttp://localhost:1317
as the value
Example creation command use
Verifying your validator
Once created, please use the Explorer URL
to confirm the transaction. If successful, you should see your validator pub key (found in yourpriv_validator_key.json
file) listed as part of the following endpoint:
Congratulations, you are now one of Story’s very first IP validators!
Validator Staking
To stake to an existing validator, run the following command:
- Note that your own

command as theCompressed Public Key (hex)
. - You must stake at least 1024 IP worth (
*1024000000000000000000 wei
) for the transaction to be valid
Once staked, you may use the Explorer URL
to confirm the transaction. As mentioned earlier, you may use our validator endpoint to confirm the new voting power of the validator.

Enabling Story API
Prerequisites:
- Ensure your full node is synced and caught up with latest blocks
Steps to enable:
- Navigate to
${STORY_DATA_ROOT}/config/story.toml
- Set
enable = true
under the[api]
section - Restart the node
Then you could use http://localhost:1317
as the -story-api
value
Migrating a validator to another machine
Before migrating your validator node to a new machine, make sure the current node is fully shut down. Attempting to restore an active validator could result in “double signing,” a critical error that may lead to the slashing of your delegated shares.
- Begin by configuring a new environment for your validator. Ensure that the new full node is fully synced to the latest block on the network.
- To avoid accidental double-signing, it’s essential to fully shut down the original validator node before activating the new instance. We recommend deleting the Story service file to prevent it from automatically restarting after a system reboot. Additionally, back up both
priv_validator_key.json
andpriv_validator_state.json
and remove it from the current server running the active validator. Skipping these steps could result in missed blocks or other penalties.
- Locate
priv_validator_key.json
andpriv_validator_state.json
in the~/.story/story/config/
directory on your new machine. Replace this file with the backup copy from your old validator.
Before proceeding, shut down the old validator on the original server and do not restart it!
- After transferring the private key file, restart the validator node on your new setup. This will reintegrate your validator with the network, enabling it to resume its validation role.
