# StakeUnavailable (/docs/errors/chain/StakeUnavailable)

An unstake or same-subnet stake transfer would dip into stake that is still reserved: the requested alpha exceeds the coldkey's free balance on that subnet after subtracting conviction `Lock` and any miner registration collateral locked against hotkeys the coldkey owns. Check `Lock` and `MinerCollateral` for the netuid; only total stake minus those reservations can move.

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

Declared at [`pallets/subtensor/src/macros/errors.rs#L175`](/code/pallets/subtensor/src/macros/errors.rs#L175).

## Remediation [#remediation]

Only free stake can move — wait out conviction locks or drain miner collateral, then retry; check locked vs free with `btcli stake list`

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