Thanks for asking. I got this list from a colleague, with his notes on some of them:
USEFUL RESOURCES on UKRAINE (primarily for donations)
https://savelife.in.ua/en/donate/ — the RETURN ALIVE FOUNDATION [Personal Note: I’ve tried this Kyiv-based charity several times and it was the easiest to use. Like the NBU site they have info on SWIFT codes and accounts, but they require setting up payees through your bank accounts, etc, etc. The easiest way to donate to this charity was via Fondy.eu: you only need a credit card, preferably one that sends a text message with a code for purchase verification. If yours doesn’t, call your card provider and ask them not to block your transaction (or to clear it if you went ahead and it’s pending).
NBU Opens Special Account to Raise Funds for Ukraine’s Armed Forces (updated) — special accounts (in different currencies) of the National Bank of Ukraine (NBU, like the US Dpt of Treasury) for the Ukrainian Armed Forces / [I tried it in in different ways, and it worked but wasn’t always very straightforward (e.g., you have to go through your bank, add a payee, which will then need to be verified, and take a few more extra steps), but it’s definitely a very credible source.
