Many extrinsics in Bittensor are subject to **weight-based fee**. In Polkadot-based chains like Subtensor (Bittensor's layer 1 blockchain), [weight](https://docs.polkadot.com/polkadot-protocol/glossary/#weight) is a measure of compute time.

In addition to the weight-based fee above, staking and unstaking operations are subject to fees based on a percentage of the quantity of transacted liquidity. When moving stake between subnets—whether through a transfer, swap, or move—a 0.05% fee is applied. If the move happens within the same subnet, no additional fee is incurred, only the weight-based fee.
