![]() ![]() The authors do very important and initial work on cross-chain security.The proposed tool can prevent invalid unlocking of assets (although not clear how in practice), and analyze the history of bridges to detect attacks.It is difficult to assess how exactly the ideas are realized. There are no implementation details or code, nor a robust evaluation.We discuss general cross-chain interoperability formalization here. Unfortunately, the tool only supports the formalization and analysis of cross-chain bridges, and not general-purpose cross-chain use cases.The work is timely and of practical implications.The proposed exposure of cross-chain bugs and the respective security models is simple yet effective.The authors contribute to the field of cross-chain security by 1) identifying the classes of bugs in cross-chain bridges 2) designing security properties for cross-chain bridges, and 3) proposing a tool that can identify bugs in cross-chain bridges.You can also do one-line reverts and other changes within SmartGit as you’re reviewing all of your changes.➡️ Title: Xscope: Hunting for Cross-Chain Bridge Attacks ➡️ Authors: Jiashuo Zhang, Jianbo Gao, Yue Li, Ziming Chen, Zhi Guan, Zhong Chen I really like SmartGit because it has a great side-by-side comparison where you can see the file exactly as it was before and after your changes. Productivity Tools SmartGit (or other Git GUI program)Īs much as I love the command line, a Git GUI program is essential for checking over your changes before you commit them. *If you have direct access to a database, this might also be where you check the database with software like Sequel Pro to make sure your flow is working before you start to build the UI on a broken server flow. ![]() You know it’s always the server’s fault, but with Postman you’ll have proof. You can save previous requests, so if you see something broken on your app, you can load up Postman and make sure the server is working correctly before you even look at the native code. ![]() You can set up authentication keys to simulate everything just like a user from your app. Next time someone sends you a URL endpoint that you usually put in your browser, put it in Postman instead, and you’ll get way more information. Use it to keep track of parameters, add auth headers, save endpoints for future use, share endpoints and payloads with teammates, and lots of other features to help you organize all the API endpoints you’re dealing with. Enable SSL proxying for the locations you specify under Proxy > SSL Proxying Settings.Install Charles Root Certificate on simulator or device.If you need to debug loading indicator bugs or other networking dependent app functionality, Charles can simulate a slow network as well.įollow two steps to use Charles for secure traffic on iOS: Most of this investigating can be done using breakpoints within your IDE, but depending on how complex your networking code is, it can be much easier and faster to get the information you need within Charles. It’s also a great tool to make sure your HTTP requests are formatted as you expect. Sometimes I’ll get assigned a new feature that isn’t fully specced out, and instead of asking everyone for the structure of the endpoints or what endpoint is hit on a certain page (which can be error-prone and out of date) I can load up the app and see for myself. The learning curve for Charles isn’t always easy, and the interface isn’t great, but it is an extremely powerful tool. This HTTP debugging tool is essential for viewing the API traffic going to and from your app. ![]() With xScope, working with your product designers will be easier than ever! Unknown colors and missing redlines are easily remedied with the tools xScope provides. Just make sure your Simulator and any design mocks are in a “Pixel or Point Accurate” mode so the numbers reflect what you see in the code. The Rulers, Dimensions, and Loupe are my most used tools. I use xScope to inspect both designer mocks and the UIs I’m creating on the iOS Simulator. ![]()
