This is a great solution called zk-rollup (zero knowledge rollup) https://zksync.io/ https://zksync.io/
It is just as secure as the base chain (unlike polygon) and has low fees and has been live for the past few months. This is a perfect solution to simple payments.
The difference between optimistic rollups and zero knowledge rollups is that you can’t deploy arbitrary smart contracts to zk rollup, it only supports a limited set of use cases, such as simple payments for now.

- hanniabu 5y agoAlso zkSync has general EVM compatibility coming in a few months
- randomopining 5y agoWhat coin does zk-rollup use? or just base Ethereum?
- TarasBob 5y agoIt can use any coin. You can send ETH or any token, including stable coins such as DAI or USDC.
- X6S1x6Okd1st 5y agothe current solutions do 'native fees' which means you pay the fee in whatever you are sending. This can't really last because I could create SPAM coin with 1B marketcap and overload the network with it. IIRC they'll eventually create their own native token when their EVM compatible rollup is out.
