TransactionInstruction split({ required Pubkey stakeAccount, required Pubkey uninitializedStakeAccount, required Pubkey authority, required bu64 lamports, })

Split u64 tokens and stake off a stake account into another stake account.

• [w] stakeAccount - Stake account to be split; must be in the Initialized or Stake state.
• [w] uninitializedStakeAccount - Uninitialized stake account that will take the split-off amount.
• [s] authority - Stake authority.

Implementation

  // 0. `[w]` Stake account to be split; must be in the Initialized or Stake state.
  // 1. `[w]` Uninitialized stake account that will take the split-off amount.
  // 2. `[s]` Stake authority.
