Cardano Eternl Wallet Integration

Prerequisites​

Generating DID from Eternl​

./dms key did eternl:myaccount

result will be:

did:key:zE4MrBkkgDczQPwp789GPUJo26cxqtWSz8J47jQgakp7RnJKH

Generating Capabilities​

Generating new capabilities:

./dms cap new eternl:myaccount

This will open the browser and ask you to sign a payload in order for dms to get a did from eternl signature.

This will create myaccount.cap file inside cap directory.

Granting with Eternl​

./dms cap grant --cap /public --context eternl:myaccount did:key:z6MkngPHCGesTFB9SfKukYqGaDkp2fJUGiCcXKE9bg49ddfB --expiry 2030-01-02

This command will open the browser, and ask you first to sign a generic message which is for dms to load the current did from eternl signature, then it will open a second browser to sign the actual capability context to grant.

This will create a capability token with cardano signature format that can be consumed.

Demonstration Video​

A demonstration video was recorded following the steps described in this README, showing the full process from DID generation with the Eternl Wallet to capability creation and granting.
