Which blockchain network is best for a fantasy sports betting dApp?

Hi everyone!

I'm developing a decentralized fantasy sports betting contest, and I'm looking for input on which blockchain network would be the best fit. A key feature is that we need to use a single network to manage our jackpot and carry-over pool, so cross-chain solutions aren't viable for us right now.

Here's a quick rundown of our needs:

• Must be a single network to handle our unified jackpot and carry-over feature
• Low transaction fees (users will be making frequent, potentially small-value transactions)
• Good adoption and user-friendly for mainstream users (for fantasy football and betting players)
• Fast transaction times
• Scalability to handle a growing user base
• Strong security (for handling user funds)

We're currently considering:

1. Ethereum Mainnet
2. Arbitrum
3. Polygon
4. Solana
5. Other (please suggest!)

What are your thoughts? Which network do you think would be best suited for this kind of dApp?

Any insights on pros and cons for each network in this context would be super helpful. Thanks in advance for your feedback!
