- below its staking cap
- staker not already set to marinade's stake authority
- withdrawer not already set to marinade's withdraw authority

createSetupInstructions

createSetupInstructions(__namedParameters: CreateSetupInstructionsParams): TransactionInstruction[]

Implementation of StakePool.createSetupInstructions
- Defined in src/stakePools/marinade.ts:207
Commmon setup instructions:
- un-deactivate stake account
Common setup instructions that are not covered:
- split stake. Why?
  - This involves generation and returning of a Keypair and Signer. Simpler to just handle this outside of this interface
- creating outputToken ATA if user does not have it yet. Why?
  - This involves a RPC call to check if the user's ATA exists.

Returns TransactionInstruction[]
