According to official news, Sui Browser now includes the source code view of the Sui framework package. The "Source Verified" tab is located next to the existing "Bytecode" tab and allows developers to click to view the source code of the following packages: 0x1 | move-stdlib, 0x2 | sui-framework , 0x3 | sui-system, 0xdee9 | deepbook.
This new feature enables Sui developers to easily find, read, understand and share Move code for easier development or auditing. For supported packages, developers no longer need to find a specific repository or branch that corresponds to published on-chain bytecode. Just look up the source code, including docstrings, in Sui Browser.
