wallet-cli chain params

Show on-chain governance parameters.

Synopsis

wallet-cli chain params [--key <name>] [options]

Description

Lists the chain's governance parameters — network-wide system settings changed by SR proposals (this CLI does not create proposals). --key returns a single one. Keys pass through exactly as the chain returns them; text output adds thousands separators and units (SUN / ms) for known numeric keys, -o json keeps raw values.

Frequently used keys:

Key	Meaning
getEnergyFee	Energy unit price (SUN/energy) — the burn rate when you lack energy; core input to fee estimation
getTransactionFee	Bandwidth unit price (SUN/byte) — the burn rate once free bandwidth is spent
getCreateAccountFee	System-side account creation fee (SUN) — part of the extra cost of sending to a fresh address
getWitnessPayPerBlock	SR reward per block produced (SUN) — feeds the voting-reward pool
getMaintenanceTimeInterval	Maintenance cycle length (ms; 21,600,000 = 6 h) — the vote-tally / SR-ranking period

For the fee-relevant prices in friendlier form, use chain prices.

Options

Option	Description
--key <string>	Return only this parameter (e.g. getEnergyFee)

Plus the global options.

Examples

A single parameter with --key:
