### Tasks

- [ ] Swap to/from Solana using `solanaDeposit` method from toolkit
- [ ] Balances should query SOL using `getBalances`

Depends on:

• Add Solana balance querying to getBalances toolkit#180
• Make Solana deposit function callable from ZetaChainClient and from browser toolkit#182

@fadeev I think the first part of the above task (adding a Solana-enabled browser extension wallet) needs to be completed before we can complete Make Solana deposit function callable from ZetaChainClient and from browser. Since RainbowKit only supports EVM wallets, and Phantom is actually a multi-chain wallet (EVM, Solana, and Bitcoin), integrating RainbowKit with Phantom only supports EVM networks. We need Solana's official wallet suite for support, which includes @solana/ wallet-Adapter-React and @solana/ wallet-Adapter-React-UI, here are the relevant docs. So I created a new issue #27
