Staking withdrawals
As of the Shanghai/Capella upgrade withdrawals have been enabled on the Beacon Chain, with the inclusion of EIP-4895.
This Ethereum Improvement Proposal enables rewards to be automatically withdrawn to the execution layer, and also provides a way for exited validators to unlock their entire balance—no gas required.

A validator client is the software that acts on behalf of the validator by holding and using its private key to make attestations about the state of the chain. A single validator client can hold many key pairs, controlling many validators.

Each 32 ETH deposit activates one set of validator keys. These keys are used to sign off on the state of the network. The lower the ETH requirement, the more resulting signatures must be saved by the network. 32 ETH was chosen as a balance between enabling as many people as possible to stake without inhibiting decentralization by bloating the size of each block with signatures.

What are withdrawal credentials?
Withdrawal Credentials is a 32-byte field in the deposit, for verifying the destination of valid withdrawals. Currently, there are two types of withdrawals: BLS withdrawal and Ethereum address withdrawal.
