[Wallet Research] Pick best authcore replacement on evm

[williamchong]

Background:

We want to migrate user of custodial wallet service away from authcore on EVM migration UI.
Need to pick one

Description:

Potential candidates

• Privy
• MagicLink
• AppKit
• Web3Auth

Look for:

• Vue@2/vanilla JS support
• Does cross-projects OAuth login yields the same wallet address?
• usage and size of existing projects
• price/plan for our MAU size

[williamchong]

Magic link seems to be best option since it is vanilla js based with wagmi support

Why

• We can integrate it with existing likerland codebase without upgrading nuxt2
• We can also use wagmi in book press and in the future when likerland is also nuxt3

Down side

• pricing
• no cross dapp wallet sharing, each dapp creates a new wallet address even with same oauth. However export private key is possible
