A place for developers to talk about building on Farcaster.

/dev

1/ With the rise of embedded wallets, a vital topic to think through is interoperability. That is, how do siloed wallets turn into global wallets.

In this thread, I explore a few paths to consider. 🧵👇

Note: approaches 1-3 are simpler; 4-7 more complex; Please consider this a draft for community discussion 🙂

Building dynamic.xyz | @dynamic | /dynamic | web3 login for everyone - embedded wallets, crypto login, user mgnt, authz and more | Demo: demo.dynamic.xyz

2/ Definitions:
Embedded wallet: Usually an email/phone/social based wallet (e.g. @dynamic_xyz)

Branded wallet: Metamask, Coinbase Wallet, Rainbow etc.(a consumer brand; has distribution)

AA embedded wallet: a layer on top of the EOA embedded wallet (e.g Alchemy or Zerodev).

1: Key replication to a branded wallet 🔃
User starts with an embedded wallet. They replicate their private key / mnemonic phrase and import it into Coinbase Wallet / Metamask etc.

Pro: user can still use the embedded wallet after replication
Con: direct key interaction is risky

2: Embedded wallet WC connection 🔌
Give the embedded wallet connection capabilities via WalletConnect and allow it to connect to any 3rd party site

Pro: straightforward for web3 users
Con: you still end up with a bunch of wallets; web2 users don't know WC

3: Asset migration ➡️
Either via EOA or AA, you “export” your assets into your branded wallet. Embedded wallet becomes less useful after asset export

Pro: easy way to move things
Con: your embedded wallet becomes useless thereafter

4: Branded+embedded wallet 🤝
The embedded wallet becomes a branded wallet as well. User logs in with same credentials into embedded wallet that they do into the branded wallet

Pro: email/social login everywhere
Con: requires distribution

5: Linking/unlinking signers 🖋️
User starts with an AA embedded wallet. The user can link their global wallet as a new signer into the AA wallet, and view/take actions from their global wallet

Pro: easy linking/unlinking
Con: requires wallets to show AA accounts

6: Multiple wallets with identity hub 🆔
Your Farcaster etc profile keeps track of your multiple embedded wallets. They are separate, but you have a profile in Farcaster that centralizes all of them

Pro: Farcaster
Con: Requires significant planning

7: Secret EIP proposals 🤐
We solve this in another way with some architecture changes to EVM and other networks, and hope for the best.

Pro: it's a secret
Con: it's a secret
