Variable ComputeBudgetConst

Type declaration

• ReadonlyprogramId: never

  Compute Budget Program address.

• requestHeapFrame:function

  • requestHeapFrame(p): TransactionInstruction

  • Request a larger heap frame for the transaction.

    Default heap is 32 KiB. Max is 256 KiB. Must be a multiple of 1024.

    Parameters

    • p: RequestHeapFrameParams

    Returns TransactionInstruction

    Since

    1.1.0

• setComputeUnitLimit:function

  • setComputeUnitLimit(p): TransactionInstruction

  • Set the compute unit limit for the transaction.

    Default is 200_000 CU. Max is 1_400_000 CU. Setting a lower limit can reduce priority fees.

    Parameters

    • p: SetComputeUnitLimitParams

    Returns TransactionInstruction

    Since

    1.1.0

• setComputeUnitPrice:function

  • setComputeUnitPrice(p): TransactionInstruction

  • Set the priority fee (price per compute unit).

    Priority fee = microLamports × computeUnitsUsed. A value of 50_000 micro-lamports ≈ 0.05 lamports/CU.

    Parameters

    • p: SetComputeUnitPriceParams

    Returns TransactionInstruction

    Since

    1.1.0

• setLoadedAccountsDataSizeLimit:function

  • setLoadedAccountsDataSizeLimit(p): TransactionInstruction

  • Set the maximum total size of loaded accounts data.

    Parameters

    • p: SetLoadedAccountsDataSizeLimitParams

    Returns TransactionInstruction

    Since

    1.1.0
