Question 1

TON JSON-RPC: Endpoint, Methods, and How to Use It

Accepted Answer

TON JSON-RPC is a JSON-RPC 2.0 interface to The Open Network, letting you query account state, run smart contract get-methods, and send transactions through a single HTTPS endpoint. This article explains the endpoint structure, common methods, authentication, and how to choose between public, managed, and dedicated TON RPC infrastructure.

Question 2

What is a TON testnet RPC and how do you use it?

Accepted Answer

A TON testnet RPC endpoint lets you interact with the TON testnet, a sandbox environment for building and testing dApps, wallets, and smart contracts without risking real TON. This article explains the available endpoints, how to authenticate, and how to choose a reliable provider for your development workflow.

Question 3

How do I connect to the TON testnet?

Accepted Answer

The TON testnet is a public sandbox for building and testing smart contracts, wallets, and dApps without risking mainnet assets. This guide covers the key endpoints, faucets, and practical steps to get your testnet environment running, plus how to choose a reliable RPC provider for your development workflow.

Question 4

What is a TON endpoint and how do I choose one?

Accepted Answer

TON endpoints are HTTP and JSON-RPC bridge endpoints that let off-chain applications read blockchain data, query smart contracts, and submit transactions on The Open Network (TON). Because TON nodes speak ADNL rather than HTTP, an endpoint such as TON Center's API or a hosted RPC provider is the standard way for wallets, bots, and backends to talk to the network.

Choosing the right TON endpoint means checking whether you need mainnet or testnet access, deciding between TON Center API v2 (liteserver-backed) and v3 (indexed), verifying rate limits, and testing the endpoint before production. This guide covers endpoint options, sample requests, and a decision checklist for developers.

Question 5

TON API: How to Choose and Use Endpoints for Mainnet and Testnet

Accepted Answer

TON API services provide HTTP and WebSocket access to the TON blockchain. Developers can choose between public endpoints, hosted APIs like TON Center and TonAPI, or dedicated node infrastructure from providers like OnFinality. This article compares available options, lists endpoint settings, and covers common setup and debugging steps.

Question 6

What Are TON Nodes and When Should You Run One?

Accepted Answer

TON nodes are software clients that store the full state of The Open Network blockchain, validate transactions, and serve data to applications. Running your own node gives you direct, uncensored access to the network, but it also requires significant operational overhead. For most developers, a hosted RPC endpoint or dedicated node from a provider like OnFinality offers a faster, more reliable alternative without the maintenance burden.

Question 7

TON Testnet: Complete Developer's Guide to RPC Endpoints, Faucets, and Setup

Accepted Answer

# TON Testnet: Complete Developer's Guide to RPC Endpoints, Faucets, and Setup The TON testnet is a public sandbox environment for The Open Network, allowing developers to deploy smart contracts, test dApps, and experiment with TON features without using real TON tokens. This guide covers everything you need to get started: RPC endpoints, faucets, block explorers, and best practices for reliable testnet infrastructure. Whether you're building a wallet, a DeFi protocol, or an NFT marketplace, the TON testnet is your first step to production-ready development. OnFinality provides dedicated and shared RPC endpoints for the TON testnet, offering high reliability and scalability for your testing workflows. With support for both HTTP and WebSocket connections, you can integrate seamlessly into your development pipeline.

In practice, the useful question is not just whether an endpoint exists. Teams should check testnet endpoint access, chain settings, faucet assumptions, staging checks, and the path to mainnet. That turns the page from a definition into a decision tool: it helps you decide what to test first, what belongs in staging, and when a production workload may need stronger isolation or clearer request visibility. If you already know the network you need, open /networks/ton after using this checklist so you can test the endpoint against your real methods.

Question 8

What is TON RPC and how do you use it?

Accepted Answer

# What is TON RPC and how do you use it? The Open Network (TON) is a layer-1 blockchain designed for high scalability and deep integration with Telegram. Unlike EVM chains, TON uses a unique architecture with sharding and asynchronous smart contracts. To interact with TON from a web application, you need an RPC (Remote Procedure Call) endpoint that translates standard HTTP requests into the binary ADNL protocol used by TON nodes. This guide explains what TON RPC is, how to choose an endpoint, and best practices for reliable dApp connectivity.

In practice, the useful question is not just whether an endpoint exists. Teams should check supported methods, traffic shape, monitoring, pricing, and the path from testing to production. That turns the page from a definition into a decision tool: it helps you decide what to test first, what belongs in staging, and when a production workload may need stronger isolation or clearer request visibility. If you already know the network you need, open /networks/ton after using this checklist so you can test the endpoint against your real methods.

Question 9

What is a TON RPC node and how do you use one?

Accepted Answer

# What is a TON RPC node and how do you use one? The Open Network (TON) is a layer-1 blockchain designed for high-speed, scalable transactions. To interact with the TON blockchain—whether you're building a wallet, a dApp, or an analytics tool—you need a TON RPC node. A TON RPC node acts as a gateway, allowing your application to query blockchain data and submit transactions. This guide explains what a TON RPC node is, the different node modes, how to choose between running your own node or using a managed provider, and best practices for production use.

In practice, the useful question is not just whether an endpoint exists. Teams should check supported methods, traffic shape, monitoring, pricing, and the path from testing to production. That turns the page from a definition into a decision tool: it helps you decide what to test first, what belongs in staging, and when a production workload may need stronger isolation or clearer request visibility. If you already know the network you need, open /networks/ton after using this checklist so you can test the endpoint against your real methods.

Question 10

What should I know about TON RPC endpoints?

Accepted Answer

# What should I know about TON RPC endpoints? TON RPC endpoints matter because Web3 applications depend on stable endpoint access for reads, transactions, dashboards, and backend workflows. The right setup should match your workload, support the networks and testnets you need, make limits visible, and give you a scaling path when shared RPC is no longer enough. For TON builders, infrastructure leads, DeFi teams, wallets, games, analytics teams, and backend engineers, this is part of production architecture. A basic endpoint can be fine for a prototype, but production systems need predictable latency, clear request behavior, reliable support, and enough observability to debug incidents.
