redelegate static method

TransactionInstruction redelegate({ required Pubkey delegatedStakeAccount, required Pubkey uninitializedtStakeAccount, required Pubkey voteAccount, required Pubkey authority, })

Redelegate activated stake to another vote account.

Upon success:

• the balance of the delegated stake account will be reduced to the undelegated amount in the account (rent exempt minimum and any additional lamports not part of the delegation), and scheduled for deactivation.
• the provided uninitialized stake account will receive the original balance of the delegated stake account, minus the rent exempt minimum, and scheduled for activation to the provided vote account. Any existing lamports in the uninitialized stake account will also be included in the re-delegation.

Keys:

• [w] delegatedStakeAccount - Delegated stake account to be redelegated. The account must be fullyvactivated and carry a balance greater than or equal to the minimum delegation amountvplus rent exempt minimum.
• [w] uninitializedtStakeAccount - Uninitialized stake account that will hold the redelegated stake.
• [] voteAccount - Vote account to which this stake will be re-delegated.
• [s] authority - Stake authority.
