Passkey signer rotation without wallet redeployment

[Miracle656]

Background

If a device is lost, the user must replace the passkey signer while keeping the same wallet address and balances.

What to build

A rotate_signer(old_key, new_key) contract entrypoint (owner-authed) that swaps the registered P-256 key atomically, plus an SDK flow that registers a new credential and calls it.

Key files

• contracts/invisible_wallet/src/lib.rs
• sdk/src/useInvisibleWallet.ts

Acceptance criteria

• New key authorizes after rotation, old key rejected
• Wallet address unchanged
• Test: rotation requires current-signer auth

I’d like to work on this issue because it contributes to improving the project's functionality, reliability, and overall user experience. I enjoy contributing to open-source projects and collaborating with maintainers to deliver clean, maintainable, and well-tested solutions.

I have experience working across frontend, backend, testing, API integration, debugging, and performance optimization tasks. I'm comfortable analyzing existing codebases, understanding requirements, implementing features or fixes, writing tests, and ensuring changes align with project standards and acceptance criteria.

My approach is to first understand the current implementation, identify the most maintainable solution, implement the required changes, add or update tests where necessary, and verify that everything works correctly before submitting a PR. I can communicate progress clearly and incorporate feedback quickly throughout the review process.

Hello maintainer I'd love to work on this job if given the opportunity I've worked on it before and I'll love to work on it again before this wave ends
I’ll add a rotate_signer(old_key, new_key) entrypoint in lib.rs that atomically swaps the registered P-256 key under current-signer auth, wire the SDK flow in useInvisibleWallet.ts to register the new credential, and ensure the wallet address and balances stay unchanged while rejecting the old key.
