VS Code extension

Before you run anchor deploy, compare your local build with what is on chain, without leaving the editor.

Install

1
Download the extension
Get tidemark.vsix from the v0.1.0 release.
2
Install it
In VS Code, open Extensions, click ⋯ and choose Install from VSIX…, or run:
shell
```
code --install-extension tidemark.vsix
```
It works the same in Cursor, Windsurf and VSCodium.
3
Run a command
Open the command palette (Ctrl+Shift+P) and type Tidemark.

Commands

Command	What it does
Tidemark: Review a build against the deployed program	Asks for a program id, fetches its ProgramData over RPC and reviews your local .so against it
Tidemark: Review two program binaries	Compares any two .so files

The report opens in the Tidemark output channel in the same layout as the CLI, with the verdict hash. A warning pops up when the risk reaches your threshold.

Settings

Setting	Default	Meaning
`tidemark.rpc`	devnet	RPC used to fetch the deployed program (finalized commitment)
`tidemark.warnAt`	high	Risk level that raises a warning

One RPC

The extension trusts the RPC you configure for the deployed bytes. Use a provider you trust, or cross-check with tidemark fetch.

Command line

npm package
