vCard Exchange

[depatchedmode]

Goals

Goal: Let people exchange contact info that includes wallet address info, and demonstrate where that fits in a vCard

Stretch: Use WalletConnect V2 messaging to subscribe to vCard updates from that associated address - and then request it via the same channel?

Rationale

What does this demonstrate about ODD?

1. (If we implement it this way) Shows how ODD can be used in a wallet client to maintain a local copy of signed messages and transaction history (in this case, of exchange events logged in the contract)

How does this support hackathon participants?

1. Creates a rich onchain data set to query
2. Provides an example of FIL native account interacting w/ a contract
3. Provides an example of how ODD/WNFS can be used to securely keep a user-owned backup onchain and offchain message history

How do we measure success? 60% of installs exchange vCards with at least 3 other people.

Details

• When two people speak the event and would like to stay in touch
  • As one of the conversation participants, I want to exchange vCard info with them, so we know how to contact each other after the event.
    • QR Code scan mode
    • NFC tap mode
  • As the ODD team, we’d like that to result in both people having the Collector app, so that we get a broader sample set.
  • As PL, when these folks exchange contacts,
• Keep a log of addresses met
  • Combined with your contacts data to make it human readable in the app without divulging any info publicly
• Simple leaderboard
• No PII needs to be stored on IPFS nor onchain
• Using Account Metadata standard extension for addresses? https://docs.google.com/document/d/1baSoCMcd8LHsOcg_KKLJLBqhqBreI2A6KldD9l86jC0/edit#heading=h.mk41nv5erwgt
• How do we represent this in a standard vCard format?
  • https://github.com/DigitalArsenal/vcard-cryptoperson
• How does this get ingested into the Contacts app?

Note: iOS has an interesting experience for defining Pronouns, I assume these will be included in some vcards we see and we should handle them prominently if they exist.
