# CannotAffordLockCost (/docs/errors/chain/CannotAffordLockCost)

The coldkey's free balance cannot cover the current dynamic subnet-creation lock cost. Compare `btcli subnets create-cost` (or `btcli query subnet-registration-cost`) against the coldkey balance from `btcli wallet balance` before registering a subnet.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`insufficient_balance`](/docs/errors/insufficient-balance).

## Remediation [#remediation]

Fund the signing account or reduce the amount; check with `btcli wallet balance`

The same explanation is available in the terminal: `btcli explain CannotAffordLockCost`.
