@mbarret3 we don’t fund ideas and we encourage that you do a proof-of-concept (POC) first. From the application page [Harmony Grants and Investments (Paused)](https://open.harmony.one/300m-on-bounties-grants-daos/apply-for-grants-or-dao) -

> 1. **500 Launches ($20M).** Applications of each launch must have prototyped a feature-full product. Harmony helps incubate these founding teams with product development, fundraising, and talent recruit. We recommend a $50K equity-free contribution each: $10K after launching a feature-complete product on our testnet, $10K after mainnet launch, $10K after forming a DAO with its community, and $20K for after 10K users.

If you agree to this, can you describe the proposal in greater lengths?

- Will there be a mobile app included?
- Will each authenticator code be tied to a wallet address, or is it a one-to-many relationship?
- How do we guarantee time sync between the device and the blockchain, or do we need to care?
- Is the smart contract performing the hashing functionality, if so how expensive will it get?
