Repporter lets you verifiably port your web2 social reputation to web3 by proving onchain that you control a web2 identity. Repporter creates onchain attestations that map OAuth identities and a wallet address for you or anyone else to view. Here's how it works:

1. A user visits the Repporter dApp, hosted e.g. at https://repporter.netlify.app
2. In order to port their reputation, the user is required to login using a web2 platform AND also sign a message using their web3 wallet.
3. Repporter verifies the web2 login and the web3 identity, and proceeds to store this attested mapping onchain.
4. The user receives a receipt that shows that Repporter attested the mapping.
5. Any user can now view the web2 identity of a given web3 address.

The main advantage of Repporter is the simple and lightweight implementation with a smooth UX. All that is needed to verify which web2 identities a web3 identity controls is a single paste+click. Moreover, the mapping mechanism relies on a fully open-source smart contract, frontend and backend, using standard OAuth functionalities for the centralised web2 service interaction. Whilst this requires some trust, it is reduced through the license and a frontend-focussed approach. The main trust assumption that is needed is that the Repporter backend correctly verifies the OAuth token prior to posting the attestation to its owner-only smart contract.

Users should have a smooth onboarding experience where they do not need to leave behind their hard-gained web2 reputation. By creating a simple application with a smooth UX, Repporter makes onboarding non-crypto-native users more feasible.

As an end-user in web3, you can provide a simple proof that you control a specific web2 handle. More importantly, other projects can easily ask users to verify that they control a handle in order to verify their web2 identity. The use cases for businesses are vast: from airdrop management to multi-factor authentication for large payments.

• Onchain storage and verifiable compute of user signature
• Attesting as Ethereum Attestation Service
• Additional web2 identities' support
• Additional networks' support
• Require users to pay for the gas needed to update their links
• Input validation, error handling
• Use a less trusted model, e.g. via zk
