# advancedDeposit

> Deposit funds to Spark using a raw Bitcoin transaction.

Non-trusty flow for depositing funds to the `SparkWallet`. Construct a Bitcoin transaction that pays to one of the wallet's unused deposit addresses, then call `advancedDeposit()` with the raw transaction hex.

  `advancedDeposit()` does not broadcast the transaction. You must sign and broadcast the transaction yourself.
