Thanks for your submission! To verify the technical implementation, please complete these steps:

1. Merge the main branch into your PR to get the latest updates
2. Run pnpm fix at the project root for consistent code style
3. Ensure your implementation includes:
   • Transpiled Anchor program in the programs folder
   • TypeScript files in the ts-programs folder
4. Run poseidon sync to synchronize program ID and keys
5. Run cargo fmt and cargo clippy for Rust code quality
6. Push your changes

Please note: This review is to verify technical completeness of the submission

Let me know once you've completed these steps and I'll review again. Thanks!

Is poseidon sync a valid command? Pulled the latest poseidon commit from master branch, ran cargo build --release to update it, but got "unexpected input"

Nevermind, got the newer poseidon version running. Ran all commands verify technical completeness, no new changes to push.
