An unbonding period is the period between a request to exit staking or cancel delegation and the point at which the assets become freely available again. The term is especially common in networks that use delegation.

During this period, the asset typically stops participating in future staking cycles but is not yet available for normal transfers or spending. The duration is determined by the blockchain protocol and can range from hours to weeks or longer.

An unbonding period is an important liquidity constraint. A user cannot always immediately sell or transfer an asset after requesting an exit from staking.

Liquid staking, represented by liquid staking, can reduce the practical impact of this waiting period by giving the user a liquid staking token that may be used elsewhere. This does not eliminate the underlying risks; it changes the liquidity model.
