Some bullet points I wrote up during the meeting. Below are proposals for the kind of stuff we need for different methods/standards. Happy to formalize it a bit more later.

Messaging Standard

• JSON interface { method: string, params?: any }
• All methods must be prefixed with arcxxxx_

Handshake

• connect multiple accounts
• account types (EOA, ARC58, etc.)
• dApp can request specific account(s)
• signal which methods the wallet supports
• dApp → Wallet: { method: 'connect', params?: { accounts?: string[] } }
• wallet → dApp: { accounts: { address: string, type: 'EOA' | 'ARC58'}[], supportedMethods: string[] }

Transaction Signing

• auth addrs
• auth addr types (EOA, ARC58, etc.)
