AIP-66 Web Wallet Communication Method?

[wilwade]

Hello! I've been pulled in by looking at how Aptos handles passkeys/webauthn for accounts per AIP-66.

One piece of the puzzle I don't yet understand about AIP-66 is how a wallet website and a dApp website communicate.

Setup: Wallet Website example-wallet.com, dApp Website dapp-example.com

1. Alice visits example-wallet.com and creates an account, transfers some APT to her address to create the account on chain.
2. Alice then visits dapp-example.com and wants to use the wallet from example-wallet.com
3. How does dapp-example.com communicate with example-wallet.com?

I looked over the aptos-wallet-adapter, but it not clear there either how one might accomplish this setup.

The closest I got is how msafe does it via iframe, but that doesn't feel like the intended path.

Perhaps I am just missing something?

Typically it would be via iframe or popup. The wallet adapter is really for extension or mobile wallets

Are there there any standards for that, or would it just be about adding your specific wallet discovery and iframe API into the aptos-wallet-adapter?

No plans to integrate with the wallet adapter at the moment. The dapp would integrate the web wallet directly
