Manual Test Plan

[pavelbrm]

Looking better. Left a few non-blocking suggestions.

[pavelbrm]

At some point (soon) it might be good to extract this into a separate predicate to be able to test it in isolation.

[pavelbrm]

This could also be extracted into a helper predicate:

func isErrSolanaTransaction(err error) bool {
	if err == nil {
		return false
	}
	
	return errors.Is(err, SolanaTransactionNotConfirmedError) || errors.Is(err, SolanaTransactionNotFoundError) || errors.Is(err, SolanaTransactionUnknownError)
}
