## Definition

Restaking takes already-staked coins, like ETH locked through a liquid staking service, and lets them also secure other networks or middleware. In return, the operator earns extra rewards on top of the base staking yield.

Restaking adds new layers of slashing risk, because the staked coins can now be penalised by both the underlying chain and the new services. The headline yields can be attractive but the risks compound.
