How to help Ukraine and Ukrainian refugees?

I'm located in Hungary, near the Ukrainian border, so I'm only familiar with Hungarian charities and the situation here.

355,000 people have crossed the border in this direction thus far.

The most active and well established charities working on-site are:

• Hungarian Interchurch Aid
• Hungarian Maltese Charity
• Hungarian Baptist Aid

These are well-known charities here in Hungary with decent track records so 100% no scam.

Donate to the Fund of the National Bank of Ukraine

The National Bank of Ukraine opens special account to raise funds for Ukraine's Armed Forces.
 
The National Bank of Ukraine has decided to open a special fundraising account to support the Armed Forces of Ukraine.
 
The central bank's decision comes after the Ukrainian government imposed martial law throughout Ukraine in response to armed aggression by Russia and the renewed threat to Ukraine's independence and territorial integrity.
 
NBU Governor Kyrylo Shevchenko announced the opening of this special account in his 24 February video address.
