How to choose a TON RPC provider for production dApps?
Key Takeaways
- TON's sharded architecture requires RPC providers that support HTTP v2/v3 and ADNL protocol.
- Shared RPC endpoints are cost-effective for development but may have rate limits; dedicated nodes offer consistent performance for production.
- Archive node access is essential for historical data queries and on-chain analytics.
- Geo-distributed endpoints reduce latency for global user bases, especially for Telegram Mini Apps.
- Evaluate providers based on uptime SLAs, request limits, and support for TON Testnet.
- OnFinality provides TON RPC endpoints with dedicated node options and multi-region support.
- Always test provider performance from your target regions before committing to a production plan.
Why TON RPC provider choice matters
TON's unique architecture—sharded workchains, shardchains, and the ADNL protocol—creates specific requirements for RPC providers. Unlike EVM chains, TON uses HTTP v2 and v3 APIs, and its native ADNL protocol is essential for low-level interactions. A provider that only supports generic JSON-RPC may not offer full TON functionality.
Running your own TON node requires significant hardware (high IOPS storage, 16+ GB RAM) and operational expertise. Managed RPC services eliminate this overhead while providing SLAs, geo-distributed endpoints, and archive access. For production dApps, especially Telegram Mini Apps serving millions of users, provider reliability directly impacts user experience.
- Sharded architecture means RPC requests may need to target specific shards.
- ADNL protocol enables direct node communication and is required for some advanced features.
- Archive nodes are necessary for querying historical state and transaction data.
- Geo-distributed endpoints reduce latency for a global user base.
Key criteria for evaluating TON RPC providers
When comparing TON RPC providers, focus on these technical and operational factors:
| Criterion | What to check | Why it matters |
|---|---|---|
| API Compatibility | Does the provider support TON HTTP v2/v3 and ADNL? | Full API support ensures you can use all TON features without workarounds. |
| Network Coverage | Mainnet and Testnet availability, plus archive node support. | Testnet is essential for development; archive nodes enable historical queries. |
| Latency & Geo-Distribution | Number of regions and measured round-trip times. | Low latency improves dApp responsiveness, especially for real-time applications. |
| Request Limits & Pricing | Rate limits, monthly request quotas, and overage costs. | Production apps need predictable pricing and no hard daily limits. |
| SLA & Uptime Guarantee | Published uptime SLA and compensation policy. | An SLA ensures accountability and reliability for mission-critical apps. |
| Dedicated vs Shared Infrastructure | Option for dedicated nodes with isolated resources. | Dedicated nodes provide consistent performance and are ideal for high-traffic dApps. |
Shared vs dedicated TON RPC nodes
Shared RPC endpoints are a cost-effective way to start building on TON. Providers like OnFinality offer shared endpoints with generous rate limits suitable for development and moderate production traffic. However, shared nodes can experience performance degradation during peak usage due to resource contention.
Dedicated TON nodes provide isolated infrastructure with guaranteed compute and bandwidth. This is recommended for high-throughput dApps, DeFi protocols, or any application where consistent latency and uptime are critical. Dedicated nodes also allow custom configurations and direct access to the node's ADNL interface.
- Shared: lower cost, good for dev/test, may have rate limits.
- Dedicated: isolated resources, predictable performance, full control.
- OnFinality offers both shared TON RPC endpoints and dedicated node deployments.
TON-specific features to look for
Beyond basic RPC, TON providers may offer additional features that enhance development:
- ADNL support: Enables direct node communication and is required for some TON protocols.
- Archive nodes: Allow querying the full historical state of the blockchain.
- WebSocket support: For real-time event streaming and subscriptions.
- REST API: Some providers offer a RESTful interface for simpler integration.
- Multi-region failover: Automatically routes requests to healthy regions for high availability.
How to evaluate TON RPC provider performance
Before committing to a provider, run performance tests from your target deployment regions. Measure round-trip latency for common RPC methods like getTransactions, getAccount, and runGetMethod. Also test archive node performance if your application requires historical data.
Many providers offer free tiers or trial periods. Use these to benchmark performance under realistic workloads. Tools like MilliNet can help compare latencies across providers from different geographic locations.
- Test latency from multiple regions using sample RPC calls.
- Check archive node response times for historical queries.
- Monitor uptime over a trial period to verify SLA claims.
- Evaluate rate limits and how they affect your application's request patterns.

Frequently Asked Questions
What is a TON RPC provider?
A TON RPC provider offers remote access to TON blockchain nodes via APIs, allowing dApps to read and write data without running their own node.
What should I look for in a TON RPC provider?
Key factors include API compatibility (HTTP v2/v3, ADNL), network coverage (mainnet, testnet, archive), latency, pricing, SLA, and dedicated node options.
Does OnFinality support TON?
Yes, OnFinality provides TON mainnet and testnet RPC endpoints, including dedicated node options. Visit our TON network page for details.
Can I use a shared TON RPC for production?
Shared RPC can work for moderate traffic, but dedicated nodes are recommended for high-throughput or latency-sensitive production apps.
What is ADNL and why is it important?
ADNL (Abstract Datagram Network Layer) is TON's native protocol for direct node communication. Some advanced features require ADNL support from your RPC provider.
