Secure private shard infrastructure lets you protect your data while leveraging all the business benefits of open-source blockchains.

Performant privacy

Snippet of Calimero's console for private shard scaling

Calimero Console

Our infrastructure management console enables you to deploy your private shard and start developing, testing and deploying contracts in a matter of seconds. Connect to private or public blockchain applications like DeFi, NFTs, on-chain KYC, and more without any compromise on confidentiality and privacy.

Solving the Enterprise blockchain dilemma

Enterprises have been developing solutions with both private and public blockchains, but they soon recognize the shortcomings of each. Private blockchains cannot provide the same interoperability or advantages as a public blockchain, while public networks, necessitate the need for security, scalability, privacy, and integration with existing systems. We are combining them all to bring the best of both worlds.
