Before using NES to host nodes, be familiar with the following precautions:

Currently, NES is available only in the AP-Singapore region.

NES supports both WebSocket and HTTP APIs through separate endpoints.
You can use NES nodes to create batches of JSON-RPC requests.
You can get an authentication credential with your NES node and construct a node URL credential to establish a connection to the node and send RPC requests.
To modify the state of the blockchain, you can only use eth_sendRawTransaction to send a raw transaction to Ethereum network. This means you cannot use NES as a wallet until you send a transaction. Generate and keep the transaction and private key on a third-party platform until then.
