ccvault.io is a closed-source Cardano wallet developed and maintained by Tastenkunst, a limited liability (GmbH) advertising company based in Leipzig Germany. Of the 7 Cardano wallets I’ve tried so far, ccvault.io is by far the most feature-rich. ccvault.io is great for sending and receiving ADA, registering to vote on Project Catalyst proposals, managing your stakepool delegation, managing your NFTs and interacting with DApps. It is classified as a light wallet because it doesn’t run the entire blockchain in your browser or mobile device, but instead connects to Tastenkunst servers to read and post transactions to the Cardano network.
ccvault.io is one of the few wallets that provides “Power User” features that can be managed in the settings. These include token fragmentation, adding metadata messages, turning “Send All” on and off, toggling “single address” and “HD address” modes, and exporting and importing wallets, to name a few.
ccvault.io has been around since January 2021, with no known security incidents to date.
Because ccvault is a light wallet, getting started, creating a passphrase, and beginning your Cardano journey takes less than 10 minutes.
With the ccvault.io mobile app for Android and iPhone you can check your balance, buy and send NFTs, and do most of the same things you can do with ccvault.io desktop. Interacting with DApps is one exception; this requires using the desktop application.
When things go awry, you can get support using their Discord ticket system. ccvault also provides limited support via their Telegram and Twitter accounts.
