Feature Request: Add ZCHF as an asset in the Cake Wallet
While Cake Wallet already offers USDT, USDC and DAI as USD stablecoins, there is unfortunately no CHF (Swiss franc 🇨🇭) stablecoin in the Cake Wallet yet. 

A Swiss stablecoin is not only interesting for Swiss Cake Wallet users. Many people around the world love the Swiss franc because it is constantly appreciating against the USD. The Swiss franc is very popular all over the world, which is why I think it would be a great thing to activate a Swiss franc stablecoin in the Cake Wallet.

The largest CHF stablecoin is the ZCHF. It is also supported by DFX, among others, and can be exchanged at DFX at any time at a rate of 1 CHF. 

ZCHF is available on the following blockchains:

- Ethereum
- Polygon
- Base
- Optimism
- Arbitrum
- BinanceSmartChain

Ethereum and Polygon would therefore be particularly interesting for Cake Wallet. Here are the links:
