I’m developing the DApps which need a scalable RPC node so we choose Moralis’ speedy one on the polygon network. But last time we found that the node was down and we’re unable to send transaction to it (at the time, we’re testing around 15 people). How many rate limit or transaction per second does it allow or do you have the node’s specification. Also, I want to know the best practice of using the speedy node whether it’s suitable for clients’ usage(expose the rpc endpoints publicly) or it’s just for the internal backend. Can we upgrade it to have more capacity or do you have any recommendation?
