# NotEnoughBalanceToPaySwapColdKey (/docs/errors/chain/NotEnoughBalanceToPaySwapColdKey)

The coldkey's free TAO balance cannot cover the coldkey swap cost, which is recycled when the swap executes. Check the balance with `btcli wallet balance` against the swap cost and top up before scheduling the swap.

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