Your network, your rules

XDC Subnet

Create a configurable network within the XDC ecosystem for private applications, specialized workloads and interoperable workflows.

On this page

A network tailored to your organization

Sovereignty

Control the network configuration, participating validators, access rules and data governance.

Scalability

Create infrastructure for an application’s workload and adjust capacity as requirements evolve.

Security

Use the XDC 2.0 consensus design, monitoring and checkpoint verification within the deployment’s operating assumptions.

Privacy

Limit access to authorized participants and keep application transactions within a permissioned environment.

Customer-owned architecture

The subnet, relayer, checkpoint contract and wallet interfaces are part of a deployment controlled by the customer.

  1. Customer subnet

    An XDC 2.0 consensus engine runs with system settings, validators, governance and access rules chosen for the deployment.

  2. Relayer

    A relayer periodically submits critical consensus data from the subnet to XDC Mainnet.

  3. Mainnet checkpoint contract

    A smart contract verifies and records the submitted checkpoints, creating a public integrity reference.

  4. Wallet APIs

    Wallet interfaces connect users and applications to the subnet’s transaction workflows.

  5. Explorer and forensic monitoring

    Network tools provide transaction visibility and consensus monitoring within the deployment’s access policy.

Interoperability & mainnet checkpointing

A subnet can maintain its own validators and permissioned application state. A relayer sends consensus checkpoints to a smart contract on XDC Mainnet, producing a public record for integrity checks without publishing the underlying private transactions.

XDC Zero handles communication between a subnet and XDC Mainnet. Endpoint contracts send and receive messages, a relayer transports the payload, and an oracle provides block-header data for validation. Applications can build data exchange and asset-transfer workflows on these components.

Checkpointing and cross-chain execution solve different problems. Each deployment must define its verification rules, operator responsibilities and failure handling. Proposed XIM research extends this model toward heterogeneous ledgers and authenticated financial gateways; it is not a production service.

Build for your use case

Private blockchain networks

Create an application network with confidential records, defined membership and organization-specific rules.

Cross-chain transactions

Coordinate messages and asset-transfer workflows between networks using an explicitly chosen verification policy.

Supply-chain security

Track the movement and provenance of goods and materials with a shared transaction record.

Decentralized applications

Deploy smart-contract applications on infrastructure configured for their security, access and scaling requirements.

Operational advantages

Cost control

Configure infrastructure and transaction models around the application’s needs; evaluate total operating and mainnet checkpoint costs.

Speed and capacity

Isolate application workloads and tune deployment resources as usage grows.

Security operations

Combine consensus controls with monitoring, operational procedures and checkpoint validation.

Guarded privacy

Define who can access network data and who can submit or validate transactions.

Validator & partner network

The XDC Subnet overview highlights SBI VC Japan, Deutsche Telekom, Contour and Zanzibar NBN in the wider validator and partner ecosystem. A subnet’s own operators and security policies remain deployment-specific.
