TON RPC Endpoints & API | OnFinality

TON RPC Endpoints on OnFinality

OnFinality provides managed TON RPC endpoints for The Open Network (TON), a high-throughput layer-1 blockchain designed for mass adoption. With OnFinality, developers can access TON mainnet via HTTP JSON-RPC without running their own node infrastructure.

What is TON?

TON (The Open Network) is a decentralized, proof-of-stake blockchain originally conceived by Telegram. It uses dynamic sharding to achieve millions of transactions per second, making it suitable for instant payments, decentralized applications, and large-scale messaging integrations. TON's architecture includes a masterchain and multiple workchains, with smart contracts and native token transfers.

Why Use OnFinality for TON RPC?

OnFinality offers authenticated TON RPC endpoints with archive access, request analytics, and a clear scaling path. Whether you are building a wallet, a DeFi product, a game, or a backend service, OnFinality provides the infrastructure to connect to TON reliably.

• Managed endpoints: No need to deploy or maintain your own TON node.
• Archive access: Query historical blockchain data for analytics and auditing.
• Observability: Monitor request usage, errors, and limits through the OnFinality dashboard.
• Global regions: Endpoints available in N. Virginia and Hong Kong.

How to Connect to TON with OnFinality

1. Create or sign in to your OnFinality account.
2. Select TON from the supported networks list.
3. Create an API endpoint (shared or dedicated, depending on your plan).
4. Test the endpoint using the example method getMasterchainInfo.
5. Monitor your usage and move critical traffic to production.

TON RPC vs Public Endpoints

Public TON RPC endpoints are suitable for lightweight testing, but they often have unclear rate limits and no guaranteed uptime. OnFinality endpoints provide authenticated access, usage analytics, and a path to higher-capacity plans for production workloads.
