Weekly report-August 7,2023

1. Added slicing operations for contract data types. This feature enables contracts to more easily and efficiently manipulate slices of arrays, strings and other data types, improving contract expressiveness.

2. This week we completed the second security audit of the Ethereum cross-chain smart contracts. The professional security team performed static scanning, function library detection and other auditing work, and produced a detailed report. The report highlighted some security risks in function invocation which we will address by making fixes and optimizations as suggested.
