authorizeCheckedWithSeed static method

TransactionInstruction authorizeCheckedWithSeed({ required Pubkey stakeAccount, required Pubkey authorityBase, required Pubkey? custodian, required Pubkey newAuthority, required StakeAuthorize authorityType, required String authoritySeed, required Pubkey authorityOwner, })

Authorize a key to manage stake or withdrawal with a derived key.

This instruction behaves like AuthorizeWithSeed with the additional requirement that the new stake or withdraw authority must also be a signer.

Keys:

• [w] Stake account to be updated
• [s] Base key of stake or withdraw authority
• [] Clock sysvar
• [s] The new stake or withdraw authority
• [s] Lockup authority if updating StakeAuthorize.withdrawer before lockup expiration.

Implementation

static TransactionInstruction authorizeCheckedWithSeed({
  // Keys
  required final Pubkey stakeAccount,
  required final Pubkey authorityBase,
  required final Pubkey? custodian,
  // Data
  required final Pubkey newAuthority,
  required final StakeAuthorize authorityType,
  required final String authoritySeed,
  required final Pubkey authorityOwner,
}) {
  // 0. `[w]` Stake account to be updated
  // 1. `[s]` Base key of stake or withdraw authority
  // 2. `[]` Clock sysvar
  // 3. `[s]` The new stake or withdraw authority
  // 4. `[s]` Lockup authority if updating StakeAuthorize.withdrawer before lockup expiration.
