# How to use the Help Each Other platform

To make donations you need:

* A [wallet](https://docs.heo.finance/introduction-to-crypto#crypto-wallet) that supports [Binance Smart Chain](https://www.binance.org/en/smartChain) (**Metamask, Trust wallet or SafePal**);
* [**BUSD**](https://docs.heo.finance/introduction-to-crypto#busd) tokens ([BEP-20](https://docs.heo.finance/introduction-to-crypto#erc-20-bep-20-and-other-token-formats)) to donate;
* A little bit of [**BNB**](https://docs.heo.finance/introduction-to-crypto#bnb) ([BEP-20](https://docs.heo.finance/introduction-to-crypto#erc-20-bep-20-and-other-token-formats), equal to 2–3 USD) to pay transaction fees.

If you already have it all or don’t need support to get it you can start [donating](https://docs.heo.finance/how-to-donate).
