    Properties

    commitment?: "confirmed" | "finalized" | "processed"

    Confirmation commitment level to wait for.

    lastValidBlockHeightOffset?: number

    Number of slots to add to the current block height when computing the transaction expiry.

    maxRetries?: bigint

    Maximum number of automatic retry attempts. Should be set to 0 for Sender.

    pollIntervalMs?: number

    Polling cadence in milliseconds. Defaults to 2,000.

    pollTimeoutMs?: number

    Overall polling timeout in milliseconds. Defaults to 60,000.

    skipPreflight?: boolean

    Bypasses Solana's preflight transaction validation for faster submission. Caller-controlled passthrough when submitting via Helius Sender (no longer required to be true). Defaults to true.

    swqosOnly?: boolean

    When true, routes exclusively through SWQOS-only mode (lower 0.000005 SOL minimum tip). When false (default), uses Sender Max: routes across multiple high-speed pathways and enters a priority auction (0.001 SOL minimum tip).
