Variants

Initialize

Initialize a stake with lockup and authorization information

Account references

0. [WRITE] Uninitialized stake account
1. [] Rent sysvar

Authorized carries pubkeys that must sign staker transactions and withdrawer transactions. Lockup carries information about withdrawal restrictions

Tuple Fields of Initialize

0: Authorized1: Lockup

Authorize

Authorize a key to manage stake or withdrawal

Account references

0. [WRITE] Stake account to be updated
1. [] Clock sysvar
2. [SIGNER] The stake or withdraw authority
3. Optional: [SIGNER] Lockup authority, if updating StakeAuthorize::Withdrawer before lockup expiration

Tuple Fields of Authorize

0: Pubkey1: StakeAuthorize

DelegateStake

Delegate a stake to a particular vote account

Account references

0. [WRITE] Initialized stake account to be delegated
1. [] Vote account to which this stake will be delegated
2. [] Clock sysvar
3. [] Stake history sysvar that carries stake warmup/cooldown history
4. [] Address of config account that carries stake config
5. [SIGNER] Stake authority

The entire balance of the staking account is staked. DelegateStake can be called multiple times, but re-delegation is delayed by one epoch

Split

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

Account references

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

Tuple Fields of Split

0: u64

Withdraw

Withdraw unstaked lamports from the stake account

Account references

0. [WRITE] Stake account from which to withdraw
1. [WRITE] Recipient account
2. [] Clock sysvar
3. [] Stake history sysvar that carries stake warmup/cooldown history
4. [SIGNER] Withdraw authority
5. Optional: [SIGNER] Lockup authority, if before lockup expiration

The u64 is the portion of the stake account balance to be withdrawn, must be <= StakeAccount.lamports - staked_lamports.

Tuple Fields of Withdraw

0: u64

Deactivate

Deactivates the stake in the account

Account references

0. [WRITE] Delegated stake account
1. [] Clock sysvar
2. [SIGNER] Stake authority

SetLockup

Set stake lockup

If a lockup is not active, the withdraw authority may set a new lockup If a lockup is active, the lockup custodian may update the lockup parameters

Account references

0. [WRITE] Initialized stake account
1. [SIGNER] Lockup authority or withdraw authority

Tuple Fields of SetLockup

0: LockupArgs

Merge

Merge two stake accounts.

Both accounts must have identical lockup and authority keys. A merge is possible between two stakes in the following states with no additional conditions:

• two deactivated stakes
• an inactive stake into an activating stake during its activation epoch

For the following cases, the voter pubkey and vote credits observed must match:

• two activated stakes
• two activating accounts that share an activation epoch, during the activation epoch

All other combinations of stake states will fail to merge, including all “transient” states, where a stake is activating or deactivating with a non-zero effective stake.

Account references

0. [WRITE] Destination stake account for the merge
1. [WRITE] Source stake account for to merge. This account will be drained
2. [] Clock sysvar
3. [] Stake history sysvar that carries stake warmup/cooldown history
4. [SIGNER] Stake authority

AuthorizeWithSeed

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

Account references

0. [WRITE] Stake account to be updated
1. [SIGNER] Base key of stake or withdraw authority
2. [] Clock sysvar
3. Optional: [SIGNER] Lockup authority, if updating StakeAuthorize::Withdrawer before lockup expiration

Tuple Fields of AuthorizeWithSeed

0: AuthorizeWithSeedArgs
