Episode 40 - Cross-chain interoperability mind-bending highway spaghetti bowl

Good morning! Some crypto friends yesterday told me about DeFi Kingdoms and I thought that I should go give it a look as the way they described it, it sounds like a really fun and profitable Play-2-Earn game in the GameFi world. I went to the website to give it a look and realized that it was on the Harmony One blockchan. I was like "Oh man. another blockchain rabbit hole to go down." So I started looking up some Harmony fundamentals and how to bridge to Harmony. I did not want to use a centralized exchange like Binance or Crypto.com and transfer my dollars into the crypto space because I am low on cash, so I wanted to figure out a way to transfer some WETH I had on Polygon to Harmony. It took me on a quest. Or in more modern terms, in a superhighway interchange spaghetti bowl.

Here was my sequence of actions:

1) Swap WETH to WONE on Quickswap

2) Use RelayChain.com to bridge WONE from Polygon to Harmony

3) Use SushiSwap to Unwrap WONE to ONE on the Harmony blockchain.

 

It took alot of trial and error to figure this out by trying Multichain.org, Anyswap.exchange, bridge.harmony.com On top of that, I had to end up buying a little bit of ONE token on crypto.com because I did not have any Harmony in my wallet to do the swap from WONE to ONE in SushiSwap, and I could not find a faucet I trusted.

 

So in the end, I never got to play DeFi Kingdom in this episode. I will save that for tomorrow on Christmas. It was an interesting road getting there though!
