        solanaBackofficeWalletService: SolanaBackofficeWalletService;
    },
): SolanaTransactionService
Parameters
- __namedParameters: {
  heliusRpcClient: HeliusRpcClient;
  solanaBackofficeWalletService: SolanaBackofficeWalletService;
  }
Returns SolanaTransactionService
- Defined in solana-services/src/SolanaTransactionService.ts:25

Methods

createTransaction

createTransaction(
    __namedParameters: {
        cuLimit?: number | "UNSET";
        cuPrice?: number | bigint | "UNSET";
        instructions: TransactionInstruction[];
        nonceInstruction?: TransactionInstruction;
        payer: Address;
    },
): VersionedTransaction
Creates an unsigned versioned transaction with compute budget instructions. The transaction has a placeholder blockhash and must be given a real one before sending (see transactionWithBlockhash).
Parameters
- __namedParameters: {
      cuLimit?: number | "UNSET";
      cuPrice?: number | bigint | "UNSET";
      instructions: TransactionInstruction[];
      nonceInstruction?: TransactionInstruction;
      payer: Address;
  }
  - OptionalcuLimit?: number | "UNSET"
  - OptionalcuPrice?: number | bigint | "UNSET"
  - instructions: TransactionInstruction[]
  - OptionalnonceInstruction?: TransactionInstruction
    Nonce advance instruction — placed first, before compute budget instructions.
  - payer: Address
Returns VersionedTransaction
- Defined in solana-services/src/SolanaTransactionService.ts:41

getMinimumBalanceForRentExemption

getMinimumBalanceForRentExemption(dataLength: number): Promise<number>
Get the minimum lamport balance needed for rent exemption at a given data size
Parameters
- dataLength: number
Returns Promise<number>
- Defined in solana-services/src/SolanaTransactionService.ts:212

getNonceInstruction

getNonceInstruction(
__namedParameters: { nonceAccount: Address },
): Promise<{ instruction: TransactionInstruction; nonce: string }>
Parameters
- __namedParameters: { nonceAccount: Address }
Returns Promise<{ instruction: TransactionInstruction; nonce: string }>
Durable nonce with its instruction
- Defined in solana-services/src/SolanaTransactionService.ts:155

simulateTransaction

simulateTransaction(
    transaction: VersionedTransaction,
    opts?: { sigVerify?: boolean },
): Promise<
    {
        response: {
            accounts: object[]
            | null;
            err: string | object | null;
            logs: string[] | null;
            unitsConsumed: number | undefined;
        };
        success: boolean;
    },

        instructions: TransactionInstruction[];
        payer: Address;
    },
): Promise<
    { lastValidBlockHeight: number; transaction: VersionedTransaction },
>
