Current status: closed alpha
What's wΞlock?
Web3 smart lock system that enables physical token gating with smart contracts including NFT and ENS.
For example, you can allow operating smart locks by users only who have certain NFTs.

How to use
1. Open the wΞlock control page in your Web3 wallet / DApps browser
2. Sign with Web3 wallet.
Only signature is needed. No transaction is required.
It is the same as logging into other dapps like OpenSea.
3. wΞlock verifies usage rights on smart contracts (*) and it opens a smart lock!
* e.g. If you have an ownership of certain NFTs.

How it works
1. Authentication: Verify a user's wallet address by digital signature
wΞlock uses digital signature verification process to verify a user's wallet address.
This is the same way as logging into other Dapps like OpenSea.
2. Authorization: Verify usage right by smart contracts
wΞlock checks if the wallet address has right to operate

Points of trust
wΞlock currently has the following points that require trust, and is not currently a completely decentralized service.
1. 3rd party APIs are used to check NFT ownership.
It is better in the context of Web3 to have your own node and aggregate data.
2. Some devices used as smart locks are made by 3rd pary.
If APIs are used to operate smart locks, the smart lock provider must be trusted.
3. wΞlock server needs to be trusted from the user's point of view.
If the Smart Lock itself has a node on top of it and can hold blockchain data, there is no need to trust it.
We are developing a product called w3a.io that solves the above problems. Use Cases

Office
@hm0429: Installed a development version of our Web3 smart lock system that can be opened by verifying an ENS/NFT ownership in our Shibuya office. (Dogfooding!) Anyone who has a subdomain of a42.eth can unlock the smart lock by signing with an Ethereum wallet.
