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_


  • 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.)
