Developers on the CKB can test and build their projects by accessing the service through the API nodes granted by Nervos.
If your RPC is remotely accessible, restrict access to the following interfaces when running CKB nodes:
Ankr is a decentralized Web3 infrastructure provider offering a distributed node infrastructure that supports a multi-chain network to help developers interact with multiple blockchains. CKB developers can now access the Ankr API and RPC to test or build their own DApps.
GetBlock is a Blockchain-as-a-Service (BaaS) platform that provides instant API access to the full nodes of multiple blockchains. CKB developers can test or build their projects using GetBlock's instant API connection to full nodes from CKB.
Unifra is a Web3 developer platform focused on simplifying blockchain development. They've built a suite of developer tools, enhanced APIs, and a node infrastructure to seamlessly build and run blockchain applications. As a member of Nervos community, Unifra provides public RPC services for CKB mainnet (Mirana).
