CACAOs on other chains

Convener=Joel
Ethereum
- ABNF & EIP 4671
Other chains
- Rocco: Core app/killer app
  - In solana’s case, Magic Eden is the app that would set the AuthN signin form
  - Web3auth supports solana already; phantom and web3auth both interested
  - But in Solana case, what’s the _IP process equiv? Any public deliberation about protocol upgrades?
  - Solana doesn’t have msg prefixing in EIP191 equiv (msg construction would need to add a prefix)
- CACAOs standardized in CASA, period?
Proposal
- CAIPXX – supports multiple profiles (1 or more per namespace)
  - Make the CAIP a SUPERSET of EIP-4361- defines ONLY THE ABNF
    - Oliver: Only the msg AND THE VERIFICATION?
    - WYC: Separate CAIP for the SIGNING and VERIFICATION
    - Juan: Require CAIP2 or local/native referenceID? WYC & Pedro: GOTTA BE NATIVE REFERENCEID
    - Oliver: Why ABNF if some wallets/VMs won’t need it? Why not IPLD or CDDL; (WYC: an ADM and a func interface baybee)- leave the serialization to the namespace/CAIP-XX files
  - EIP 681 – DeepLinking – decoupled generic deep link into 835
- Namespaces
  - Eip155/caip74/eip4361-eip191 (uses EIP191)
  - Eip155/caip74/eip4XXX-eip712 (when SIWE v2 supports EIP712)

Action items

Here are some action items that we agreed on.

Create CAIP-XX

Should state which properties to be included
Should state that the chain specific impl should include a proof
Can include SIWE as an example

Add CAIP-XX for eip155 namespace

As an example of how to implement CAIP-XX in a namespace

Add CAIP-XX for another namespace (e.g. Solana)

Copy the eip4361 ABNF if possible.
Describe the proof used.

Update CAIP-74

To mention that CAIP-XX is used
Update each namespace to register a CAIP-74 header and signature type
