Disclaimer: The Cardano testnet is for testing purposes only. We encourage all certificate holders to test their certificates to ensure they can redeem their ADA.
Test Ada holds no value and cannot be exchanged. All certificate holders will be required to redeem again when Cardano SL launches. Please keep your certificate or redemption key safe.


Q: When will there be a Cardano Blockchain Explorer?

A: The Cardano Blockchain Explorer, which will allow you to see address and transaction information, is scheduled for release before May 1, 2017.

Q: Will we support iOS and Android?

A: Daedalus is what is known as a “full” or “thick” client. Daedalus is running the Cardano protocol and participating directly in the network. Full clients are usually unable to run on a mobile operating system. Later, Cardano will also have “light” or “thin” clients. Light clients only hold transaction information and private keys, and interact indirectly with the protocol, usually through a service or public network node. Light clients have their own unique security concerns and are a little further along on the Cardano roadmap.

Q: Is there a Win32 installer?

A: No, Cardano does not support 32bit Windows at the moment. Only 64bit is supported.

Q: I can’t open the installer file.

A: If you downloaded the installer through Internet Explorer, try downloading it through Google Chrome instead. There have been multiple reports that the download did not work correctly on Internet Explorer.

Q: I'm stuck at the loading screen, "Connecting to network". What should I do?

A: Please check your internet connection and note that connecting might take up to half a minute in some cases. If the application still cannot connect, try restarting. If that doesn't help, please report a bug.

Q: I'm stuck at the loading screen, "Syncing blocks" at X.X%. What should I do?

A: Please check your internet connection. If the connection is stable but syncing is still freezing, try the following:

  1. WIN: Stop the application, go to "C:\Users\<username>\AppData\Roaming\Daedalus\DB-0.4" and remove its contents, start the application again.
  2. MacOS: Stop the application, go to "/Users/<username>/Library/Application Support/Daedalus/DB-0.4" and remove its contents, start the application again.
  3. If that doesn't help, please report a bug.


Q: Was I Force Vended or Paper Vended?

A: Force Vended: If the ADA exchange was unable to contact you via email or phone and/or you did not go through the Ada Voucher Vending Machine, then you were probably force vended on March 25th, 2017. In addition, some users who vended through the AVVM may have been force vended as well because of technical issues. In this case, your AVVM certificate(s) will not redeem, you must use the ones received in your email. Note that all force vended emails are sent from [email protected]

A: Paper Vended: During force vend, some emails failed to deliver. In this case, the certificate was mailed via certified mail. The seed or redemption key is encrypted, so you must use the paper vend redemption tab to redeem.

Q: I can’t redeem my paper vend.

A: Unfortunately, the font used on the certificate makes it difficult to distinguish between 0 (zero) and O (capital o); and I (capital i) and l (little L). You will need to try different combinations of 0, O, l and I.

Q: Force Vended: How do I match the Ada code from my receipt to a certificate, if I have multiple certificates?

A: The only way to decrypt the force vended certificates is with the secret information sent to you on your receipt. You will need to try all combinations of receipt information to certificate to decrypt.

Q: How do I decrypt my encrypted certificate?

A: You can drag and drop your decrypted or encrypted certificate into the Daedalus redemption box. To decrypt, enter the 9-word passphrase given to you during vending.
