Modern C++ not only enhances the usability of the C++ language itself, but the modification of the auto keyword semantics gives us more confidence library development. Concepts verify the compile- time of template parameters, further enhancing the usability of the language. In conclusion, as an advocate and practitioner of C++, we always maintain an open

Matthew Jiang Director of Security Team @ BlockSec Motivation Background Design 1 2 3 Capability Usability Conclusion 4 5 6 Outline Motivation Why do we develop Rustle? Emerging chains with Rust as Wormhole - $321M Lack of owner-check secp_ix can be controlled with a fake accs.instruction_acc Usability With complex technology stack, Rustle is easy to use Easy to use • Easy to set up: run a few macOS, Docker Launch Rustle with a single command in multiple platforms Usability CLI, CSV, Notion, and etc. Usability Results in different formats Extend Rustle to support locating new vulnerabilities

developing • Combine usability & performance • Work nicely with Xcode Playground, support macOS & Ubuntu currently Playground “Script Language Feeling” is very important for usability. WTF it is ??? performance. • Strongly optimized. Cons: • Hardly debug. (can’t print intermediate value) • Poor usability. Now, we have the Third mode TFiwS Mode let x : Tensor = [[1,2,3], graph, feeling like eager execution. • This is the key to enable natural control flow and debug usability • Therefore, we can’t. Direct bridging is exactly traditional graph mode. Not TFiwS mode. WTF
