{% hint style="warning" %}
Currently YAR supports all EVM-based blockchains (it is about 230 chains), but it is tough to find test coins for not-so-popular but still valued networks. If you have some free coins of any (listed or unlisted) EVM-based chain, please share them with us.

Just donate it on **0x51155c8E42b1d0caEF3A0c6653d7b18db384d38f** and send a message with the "[Bridge Message](https://connect.testnet.yarchain.org/apps/message)" from the Donated address to the "Receive on YARchain TestNet: **0x51155c8E42b1d0caEF3A0c6653d7b18db384d38f** address.

Enter the BlockchainName that you donated or the BlockchainName that you want to add to the YAR interconnector.
