title_body: Is there an equivalent to the Wallet Connect protocol in the Cardano ecosystem?
upvoted_answer: There is no open standard published right now, but work is ongoing to create one.
  Emurgo is working on porting the EIP-0012 Ergo standard that the Yoroi Ergo dApp connector is using to Cardano. Have a look at the CIP-Dapp-Connector pull request.
