Westmint RPC & Dedicated Node Infrastructure | OnFinality

Westmint is the test network for Statemine and Statemint, the common-good parachains on Kusama and Polkadot that enable the hosting of arbitrary assets—both fungible and non-fungible. Running on the Westend relay chain, Westmint provides a sandboxed environment for developers to experiment with asset creation, management, and transfer logic before deploying to production.

Why Use Westmint RPC?

Developers use Westmint RPC endpoints to interact with the test network for a variety of purposes:

• Smart contract testing: Validate asset-related pallets and cross-chain interactions.
• Wallet integration: Test asset transfers and balance queries.
• Backend validation: Simulate real-world transaction flows.
• Staging releases: Verify upgrades and new features in a risk-free environment.

Westmint Node Infrastructure on OnFinality

OnFinality offers dedicated node infrastructure for Westmint. This means you can deploy a private node tailored to your team's needs, with dedicated resources and no rate limiting from shared endpoints. Dedicated nodes are ideal for:

• Consistent, reliable access during development cycles.
• High-throughput testing scenarios.
• Archive and trace data access for deep historical queries.

Key Features

• Network: Westend relay chain (testnet)
• Protocol: Substrate JSON-RPC
• Transport: HTTP and WebSocket
• Node types: Dedicated nodes with optional archive and trace capabilities
• Common use cases: Contract testing, QA, staging releases, wallet integration testing, backend validation

How to Connect to Westmint with OnFinality

1. Create or sign in to your OnFinality account.
2. Navigate to the Westmint network page.
3. Deploy a dedicated node or create an API endpoint (if available).
4. Test your endpoint using a simple RPC call like chain_getBlock.
5. Monitor request usage, errors, and limits before moving critical traffic.

When to Use a Dedicated Westmint Node

Consider a dedicated node when:

• Your team needs stable, predictable performance.
• You require archive or trace data for debugging.
• You want to avoid contention from public endpoint traffic.
• You need enhanced monitoring and support.

Westmint vs. Production Networks

Westmint is strictly a test network. Production applications should use Statemine (Kusama) or Statemint (Polkadot) mainnet endpoints when ready for live users. OnFinality supports those networks as well, ensuring a smooth transition from testing to production.
