The built-in helpers cover common flows. wallet.execute(...) is the escape hatch when you still want hosted preparation but need your own instruction set.

​
What it does

wallet.execute(...) prepares a transaction for an existing Swig wallet from a list of Solana instructions you provide. Use it when:
  • the transfer and swap helpers are not enough
  • you already know the exact instruction bundle you want to run
  • you still want the backend to prepare the final wallet transaction

​
Example

const prepared = await wallet.execute({
  instructions: [
    {
      programId: targetProgramId,
      accounts: [
        {
          pubkey: writableAccount,
          isWritable: true,
        },
        {
          pubkey: readonlyAccount,
        },
      ],
      data: Buffer.from(instructionData).toString('base64'),
    },
  ],
  addressLookupTableAccounts: [lookupTableAddress],
});
The SDK normalizes the instruction input and sends it to the hosted execute endpoint for preparation.

​
What still applies

This is still a prepared transaction result. That means:
  • your app still checks signatureRequests
  • the client still signs if required
  • your app still chooses direct submission or sponsor submission

​
When not to use it

If you want full protocol control, custom role or action construction, or instruction-by-instruction authoring without the hosted backend, use the Protocol SDK instead.
