xx Network Node Access & Dedicated Infrastructure

Use OnFinality for xx network node access, API infrastructure, and dedicated node services. OnFinality supports teams that need reliable infrastructure for xx network applications, validators, and backend workflows.

What is xx network?

xx network is a fast, low-fee quantum-ready layer 1 blockchain built in tandem with the most private communications network in the world (cMix). Founded by the godfather of digital currency and privacy technology David Chaum, the xx network mainnet launched in November 2021. Nominated Proof-of-Stake (NPoS) incentivizes coin holders to run and elect nodes as well as to participate in the governance of the platform via on-chain DAO. The total supply of coins will grow to about 1 billion xx coins over the next five years and will be offset by a number of deflationary mechanisms.

By leveraging the xxDK, any application or blockchain can route their traffic through the xx network's communications layer in order to provide metadata privacy and quantum-secure encryption for all types of data communications. xx messenger, the first ever decentralized, quantum-secure, and E2E encrypted messaging app, is the first of many real-world applications built on this technology. Available on all major app stores, xx messenger's performance and unprecedented privacy has already attracted daily users in more than 65 countries.

Why use dedicated xx network nodes?

Dedicated nodes provide exclusive access to the xx network without sharing resources. This is critical for production dApps, validators, and services that require consistent performance, low latency, and full control over node configuration. OnFinality offers one-click deployment of full, archive, and validator nodes on managed infrastructure.

What developers use xx network RPC for?

Developers use xx network RPC endpoints to query blockchain data, submit transactions, and integrate with wallets, explorers, DeFi products, analytics tools, and backend services. Reliable RPC access is essential for building and maintaining applications on the xx network.

xx network node types available on OnFinality

• Full node: Synchronized with the latest chain state, suitable for most applications.
• Archive node: Stores all historical state, enabling deep queries and analytics.
• Validator node: Participates in consensus and secures the network.

All node types support JSON-RPC and WebSocket protocols.

How to get started with xx network on OnFinality

1. Create or sign in to your OnFinality account.
2. Select xx network from the supported networks list.
3. Deploy a dedicated node or create an API endpoint.
4. Test the endpoint with the example method chain_getBlock.
5. Monitor request usage, errors, and limits before moving critical traffic.

OnFinality provides monitoring, alerts, and support to ensure your xx network infrastructure runs smoothly.

xx network RPC and developer resources

For xx network, the useful question is not just "is there an endpoint?" but whether managed node infrastructure fits the chain, workload, and operational model.

Best fit: mainnet production workflows for production apps, dev tools, and workloads.

What builders usually check first:

• Run managed node infrastructure for app backends, validators, indexers, or operations teams.
• Reduce in-house maintenance while keeping more control than a shared public endpoint.
• Use isolated resources when the workload needs clearer operational boundaries.

Supported capability notes:

• Managed xx network node infrastructure for production apps, dev tools, and workloads.
• HTTP plus WebSocket connectivity for app, backend, and integration workflows.
• Historical data access for analytics, audits, and state lookups.
• Debug-friendly trace access for transaction analysis and incident review.
• A dedicated-node path for teams that need stronger isolation or capacity planning.

Decision notes:

• Environment: mainnet. Protocol family: Substrate JSON-RPC.
• HTTP plus WebSocket connectivity is listed for supported app and backend workflows.
• Archive support is available for historical state or older chain-data queries.
• Trace support is available for transaction debugging and execution analysis.
• Dedicated node options are available when the workload needs isolated resources or more operational control.

A quick connection check usually starts with chain_getBlock, then moves into the exact methods your wallet, dashboard, bot, indexer, or backend service needs.

Planning the next step:

• Dedicated infrastructure is the right path when your team needs node-level control, isolation, or managed operations.
• Use the page to confirm the chain, node service path, and next step before planning deployment or migration work.
