Hey, please add your network using custom network feature on mobile.

Hi @Milerius

I created this pull request while doing integration with alpha-wallet which uses this wallet-core sdk. And rootstock is not supported by wallet-core due to which integration will be incomplete.

I added rootstock as custom network but still we need this integration to support the rootstock coin type. So that wallet could use the correct derivation path here

The purpose of this pull request is not only to list rootstock network but to support the coin type as there are many other wallets using this sdk.

I request to reconsider this pull request as it will open doors for rootstock network integration with multiple wallets using this sdk. 🙏
