This C++ library is used to sign requests for authentication and orders sent to Paradex. The signature is passed with every authertication request and order and proves that whoever sent this it has access to a private key of the account.
Trading programs written in C++ provide superior performance vs other languages. For that reason most of low latency traders use C++.
This library will allow them to integrate with Paradex and improve quality of liquidity on Paradex' order books.
This in turn will increase trading volume and transactions on Paradex, StarkNet and Ethereum networks.
Average latencies of signing a Paradex order using different language libraries:
| Language | Average latency milliseconds |
|---|---|
| Python with C extension | 37 |
| Go | 1.7 |
| Rust | 0.2 |
| C++ | 0.4 |
C++ library using 3rd party C++ libraries and 3rd party StarkNet Rust library: https://github.com/xJonathanLEI/starknet-rs.
