# Account Linking ## Problem Using a new app may may require an on-chain transaction. For example, signing up for Farcaster requires making a transaction to the Registry to get an fid. Using your primary wallet to make this transaction may be impractical for a few reasons: 1. Your wallet is on your ledger, at home 2. Your wallet is on your desktop, and you’re on your phone 3. Your wallet is available, but you’re having trouble connecting 4. You don’t trust this app, and would prefer not to have it come close to your wallet ## Solution The app creates a new wallet, uses a paymaster to cover the transaction costs and can charge you in fiat if necessary. The problem is that you now have a wallet for each new app and remembering the recovery phrases is impractical. An account linking system might help. The new wallet can nominate another account as its recovery address. The recovery address can move the assets in the wallet to a new location after a configurable delay. Users can set their own primary wallet as a recovery, nominate a friend or use a third party service. There are a couple of ways this can be implemented: 1. **Special purpose**, where the recovery logic is built into the contract issuing the on-chain asset. Apps can create regular EOA's which are free but the downside is that recovery only works for that asset and not other things that may end up in the wallet. 2. **General purpose**, where the recovery system is baked into the new wallet which is a smart contract. Apps must deploy more expensive smart contracts but all kinds of assets can be recovered.

A Turing Complete Social Protocol

Farcaster and Bitcoin are very different networks but share a parochial approach to problem-solving. Bitcoin lets users store and move money without a trusted third party, while Farcaster does the same for text. Describing Farcaster as a decentralized, public, and text-centric social network would be accurate. Many apps have a "twitter-like" feel, with a text feed generated from a set of "follow" relationships. Developers are starting to push the limits of the current design, with apps focussed on image and video sharing, physical presence, and on-chain ownership. People want Farcaster to act more like Ethereum and less like Bitcoin, allowing more degrees of freedom and creativity. Could Farcaster become a "Turing-complete" protocol allowing different social networks to be built? Or is a unique architecture needed for each? Achieving Completeness Farcaster already has essential building blocks like decentralized identity, text storage, and graph relationships. But building diverse networks like Facebook, LinkedIn, YouTube, or Whatsapp requires a few more elements: Flexible schemas so that devs can introduce new content and metadata types without a protocol upgrade (e.g., polls) Context separation so that users can keep identities, graphs, and data segregated across networks. Long-term storage so that users don't have to discard older data which is valuable on some networks.

What’s next for Farcaster? (Apr 23)

With the launch of Hubs now in its final phases, we wanted to recalibrate our priorities as a community. This document is a draft of some goals, problems and a few early solutions and we’re looking for input from casters. Goals Increase the number of people creating useful content on Farcaster. Increase the number of developers building on Farcaster. Achieve credible neutrality. Make money to keep funding protocol development. Stack-Ranked Problems Make sure that Hubs are working as expected

Farcaster Wallets

Users sign up for Farcaster by registering an fid using an Ethereum wallet. Apps can be authorized to act on the user's behalf by providing them with a signature from this wallet. Apps & Wallets The default line of thinking is that users should use general-purpose wallets to register, and apps can get signatures via WalletConnect. This is convenient for users who have a wallet and for app devs who don't want to deal with the headache of building a wallet. But in practice, the user experience is bad enough to hinder Farcaster’s adoption. In particular: Users without a wallet must set one up first before using Farcaster. Signing messages is confusing and intimidating to the average user. Wallet Connect does not always reliably establish connections.

A new home for our contracts

Farcaster's identity layer comprises two contracts: a fully decentralized Id Registry and a moderated Name Registry. These contracts are on Goerli but must be deployed to a secure and stable network soon. Which one of the many L1 and L2's is the right home for our contracts? Requirements Farcaster Id Registry issues fids which are unique, numeric identifiers like 12398. It is important that: Registration is very affordable (< $1 in tx fees). Ownership is fully decentralized and cannot be revoked. Ownership is secure against motivated attackers.
