Public VeChainThor mainnet and testnet nodes are embedded in the Sync, it's recommended that you can develop or user apps built on VeChainThor directly in Sync.
Additional public nodes are available for development and testing. The URLs are as follows:
- Mainnet public node: https://vethor-node.vechain.com/doc/swagger-ui/
- Testnet public node: https://vethor-node-test.vechaindev.com/doc/swagger-ui/
You can just open it in the browser and a swagger page will appear, which will easily help you interact with VeChainThor blockchain. Please note that the public nodes are not designed for the production environment, and VeChain Foundation does not guarantee the reliability and availability.
