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 (see proposal create); this command only reads them. TRON only: an EVM network has no such parameter set and fails with family_mismatch. --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:

wallet-cli chain params --key getEnergyFee --network tron:3448148188

Key    getEnergyFee
Value  210 SUN

| Key                        | Value          |
| -------------------------- | -------------- |
| getEnergyFee               | 210 SUN        |
| getTransactionFee          | 1,000 SUN      |
| getCreateAccountFee        | 100,000 SUN    |
| getWitnessPayPerBlock      | 16,000,000 SUN |
| getMaintenanceTimeInterval | 21,600,000 ms  |

wallet-cli chain params --network tron:3448148188 -o json

{"schema":"wallet-cli.result.v1","success":true,"command":"chain.params","data":{"params":[{"key":"getEnergyFee","value":210},{"key":"getTransactionFee","value":1000},{"key":"getCreateAccountFee","value":100000}]},"meta":{"durationMs":19,"warnings":[]},"chain":{"family":"tron","network":"tron:3448148188","chainId":"3448148188"}}

Output¶

data.params[] — one entry per parameter:

Field	Type	Meaning
`key`	string	Parameter name, verbatim from the chain
`value`	number	Raw chain value, no unit suffix (text adds SUN / ms). Absent altogether for a parameter the node reports without one. The port that carries it is typed `number \\| string`, but the TronWeb gateway behind it only ever yields numbers

Exit status¶

0 success · 1 execution failure (rpc_error) · 2 usage error (not_found — --key doesn't exist; invalid_value).
