Public Nodes

Public nodes allow you to test all the features without setting up your own node. Below are the available nodes for development and testing.
  1. 1.
    The public nodes are not designed for the production environment, and VeChain Foundation does not guarantee the reliability and availability.
  2. 2.
    VeBlocks Public Nodes is a community project to support all developers and allow them everywhere-access to the blockchain, without the need to have a full node with them. For more information, please visit VeBlocks Public Nodes
