Is it possible to transfer tokens to account declared in remaining accounts?

Question

Try to transfer tokens to one of the account declared in remaining_accounts list.

Here's the way I create CpiContext:

let cpi_context = CpiContext::new(ctx.accounts.token_program.to_account_info(), 
    Transfer {
        from: ctx.accounts.account_x.to_account_info(),
        to: ctx.remaining_accounts.first().unwrap().to_account_info(),
        authority: ctx.accounts.owner.to_account_info().clone()
  });

I got error related to CpiContext lifetime mismatch. Exact log error: lifetime mismatch ...but data from ctx flows into ctx here.

Why I want to use remaining accounts to transfer tokens? This transfer is optional depending on whether user decides to pass the account (referral links/affiliation). Other methods than passing account as remaining accounts to implement the optional transfer will be also highly appreciated.

Resolved my problem by manipulating Rust's lifetime in instruction as in answer. You can checkout entire implementation here: https://github.com/invariant-labs/protocol/pull/219 — wojciech_cichocki, Jul 10 '22 at 10:48

Make sure that you help out Rust's lifetime inference in your instruction:

pub fn your_instruction<'info>(ctx: Context<'_, '_, '_, 'info, YourContext<'info>>, ...)

Yep, that's solution. I will also present entire code as It's open-source. Thank you – wojciech_cichocki Jul 10 '22 at 10:34
