CAIP10 support for Arweave Wallets

[rsoury]

Arweave compatibility with CAIP10

This is a low priority enhancement that should eventually be applied to the Ceramic Libraries.

I've created an Auth Provider here: https://gist.github.com/rsoury/72e0a79210ea156b2110fd3c19b2bb58
The intent is for compatibility with https://github.com/ceramicnetwork/js-ceramic/tree/develop/packages/blockchain-utils-linking

While desiring and attempting to develop the support, I soon realised that https://github.com/ceramicnetwork/js-ceramic/blob/develop/packages/blockchain-utils-validation is a dependency for the Core Ceramic Node meaning that integration would require a fork of the entire node.
Correct me if I'm wrong on the above statement.

I'm unsure at the moment if running a forked Node is advised.

In the meantime, I'll use authId & authSecret method for Arweave-based DID authentication.

Hi @rsoury thanks for starting work on Arweave support!

There are a few things to note:

• Arweave support needs to be added to CAIP-10, in CASA namespaces
• 3ID Connect auth flows are about to be sunset, in favor of DID PKH and CACAO auth
• The main method that will be relevant going forward in AuthProviders is requestCapability
• We are working on making it easy to generalize SIWE to "Sign-in with X" in the CASA working groups
• There are a few other steps needed to complete an integration, which are not completely defined yet.

As you can see we are in the middle of a transition period with our auth approach. I would advise waiting for a few weeks at which point it will be easier to contribute support for a new chain. If you really need support in the current format then using a fork would be advisable!

Is there any documentation regarding DID PKH and CACAO auth, so that we can develop on technology that is going to be maintained?

There will be more documentation coming. For now there is:

• https://github.com/w3c-ccg/did-pkh/blob/main/did-pkh-method-draft.md
• https://github.com/ChainAgnostic/CAIPs/blob/master/CAIPs/caip-74.md
