DepositReceipt: { dropletsFeePaid: Numberu64; dropletsReceived: Numberu64; lamportsStaked: Numberu64; referralFeePaid: Numberu64 }

Breakdown of a single deposit into the stake pool

Type declaration

  • dropletsFeePaid: Numberu64

    Total number of droplets paid by the user in deposit fees, including referralFeePaid

  • dropletsReceived: Numberu64

    Number of droplets (1 / 10 ** 9 scnSOL) the user should receive in return for the deposit, with deposit fees deducted

  • lamportsStaked: Numberu64

    Number of lamports that was staked/deposited

  • referralFeePaid: Numberu64

    Number of droplets paid by the user in referral fees. This is a part of dropletsFeePaid, i.e. deposit fee paid to socean = dropletsFeePaid - referralFeePaid

TransactionSequence: TransactionWithSigners[][]

Type declaration

  • stakeAccount: PublicKey

    The stake account to make this withdrawal from. Can be a validator stake account, transient stake account, or the pool's reserve stake account.

Functions

  • Calculates and returns the expected amount of droplets (1 / 10 ** 9 scnSOL) to be received by the user for staking SOL, with deposit fees factored in. Note: if an epoch boundary crosses and the stake pool is updated, the scnSOL supply will no longer match and the result of this function will be incorrect

    Parameters

    • lamportsToStake: Numberu64

      amount of SOL to be staked, in lamports

    • stakePool: StakePool

      the stake pool to stake to

    Returns DepositReceipt

    the amount of droplets (1 / 10 ** 9 scnSOL) to be received by the user

  • Calculates and returns the expected amount of droplets (1 / 10 ** 9 scnSOL) to be received by the user for staking stake account(s), with deposit fees factored in. Note: if an epoch boundary crosses and the stake pool is updated, the scnSOL supply will no longer match and the result of this function will be incorrect

    Parameters

    • lamportsToStake: Numberu64

      SOL value of the stake accounts to be staked, in lamports

    • stakePool: StakePool

      the stake pool to stake to

    Returns DepositReceipt

    the amount of droplets (1 / 10 ** 9 scnSOL) to be received by the user

  • Calculates the withdrawal procedure - how many lamports to split and withdraw from each validator stake account given a desired number of droplets to withdraw.

    returns:

    Array of ValidatorWithdrawalReceipt, where Sum of all their dropletsUnstaked must = withdrawalAmountDroplets Pass this array directly to getWithdrawStakeTransactions()

          Returns array with single elem if withdrawing from reserve account
    
    throws

    WithdrawalUnserviceableError if a suitable withdraw procedure is not found

  • Initializes a DepositStake stake pool instruction given the required accounts and data This instruction assumes that the depositStakeAddress stake account's withdraw and deposit authority has already been set to stakePoolDepositAuthority.
