Buying Ireland Domiciled S&P500 ETF?

Hey there, you can actually use and of the online brokerages on the Seedly platform which are in this list here: https://seedly.sg/reviews/online-brokerages

I would say two of the more compeitive ones are FSM ONE and SAXO for a modern interface and also relatively lower charges for US stocks. (even though Ireland Domiciled)

However, thing to note is that some in the community often use Interactive Brokers as well (for accounts funded more than USD10k) so that's one which you can consider as well.

Cheers!
