This is a Rust command line program for scanning the Ethereum blockchain for USDT transfers within a time span and amount span.
It needs a fully synced local installation of the geth node for the web3 compatible Rust library. Or you can use a service like https://quiknode.pro for the RPC interface, but this can be very slow and expensive, because it has to make potentially millions of API requests, depending on the filter period.
First install Rust, e.g. from https://rustup.rs.
You can build the program with cargo build --release. Example which lists all transactions of at least USDT 10 million on 20th November 2021:
./target/release/ethscan http://localhost:8545 2021-11-20 2021-11-21 1e7 1e42

number of transactions: 13, amount sum: 517127652.60 USDT
The output can be redirected to a CSV file for using it with other programs, for example a spreadsheet program or gnuplot.
As you can see in the example, scientific number notation for the amount range is also supported. Another example would be 0 1e42 to get all transactions within the specified time period.
Scanning one day needs about 5 minutes, with a local connection on the same computer to a geth node.
First install geth, as described here: https://geth.ethereum.org/docs/install-and-build/installing-geth and do a full sync of the blockchain. See the geth manual for details, but you can do it like this:
geth --syncmode "fast" --cache 1024
Depending on your computer and internet connection, this might need a few days, 1 GiB RAM for the cache, and about 500 GiB on your harddisk for storing the blockchain. For best performance, use a SSD for the data directory location (default location depends on the operating system, or can be specified with a command line argument).
For using it from the Rust application, you need to run it with RPC service enabled:
geth --cache 1024 --http --http.port 8545 --http.addr localhost --http.api personal,eth,net --http.corsdomain '*'
This listens to incoming connections from localhost, so the Rust application needs to run on the same computer. You could also bind it to the address 0.0.0.0 to access it from any computer, but this might be a security problem.
It could be enhanced to allow other evaluations as well, for example Ether transactions, or other ERC-20 tokens or NFTs.
