I use the service provided by infura.io to connect to the Ethereum network
I found some problems when using, please help me to solve
I use JSON-RPC to get the data
The main purpose is to process deposits USDT-ERC20
I found that etherscan provides this interface service, which will greatly optimize and reduce the number of times I communicate with infura
example:
http://api-cn.etherscan.com/api?module=account&action=tokentx&contractaddress=0xdac17f958d2ee523a2206206994597c13d831ec7&page=1&offset=10&sort=desc&apikey=9JHC1C7QSPWYDVTD28FGT2V8EWPBHQKPSJ
Test apikey, don’t worry
Return data:

0xdac17f958d2ee523a2206206994597c13d831ec7 is the USDT-ERC20 contract address
This method requests data to return the latest 10 transaction records of USDT-ERC20
I need an interface similar to this, I want to ask whether infura supports the method like etherscan to get the data I need
I found that using traditional JSON-RPC requests to return transaction records, it has been unable to meet USDT-ERC20
Each block of Ethereum may contain more than 50-100 USDT-ERC20 transaction records
