The TON blockchain is becoming one of the more interesting for developers and Web3 enterprises. Developers who create crypto wallets and decentralized applications on TON need a way to communicate with the network in real time. That’s where TON RPC comes in.
RPC, or Remote Procedure Call, is the technology that allows your wallet to talk directly to the blockchain: fetch balances, send transactions, and get block updates. Instead of running your own server and maintaining a full node, you can use a ready-made service like NOWNodes to access TON RPC instantly.
Why TON RPC Matters for Wallet Development
When building a crypto wallet, one of the most important requirements is reliability. Users expect instant balance updates, smooth transaction processing, and accurate confirmations. TON RPC provides this direct link to the blockchain.
By connecting to a hosted TON endpoint, your wallet can:
- Show balances and transaction history in real time
- Broadcast transactions to the network securely
- Interact with smart contracts on TON
For developers, the biggest benefit is that you don’t need to manage heavy infrastructure. You simply plug into an RPC endpoint and start building.
Getting Started with TON RPC via NOWNodes
To integrate TON using NOWNodes, you first need an API key: just sign up and choose a plan. After getting your API key, you should come to NOWNodes TON API Documentation and pick the method what you need.
This URL becomes the bridge between your wallet and the TON blockchain. With it, you can send RPC requests and receive blockchain data in JSON format.
For instance, if you want to fetch the balance of a specific address, you can call the getBalance method through this endpoint. The request and response are lightweight, making it easy to integrate even into mobile wallets.
Example: Checking a TON Wallet Balance
Here’s a simple example in JavaScript with this endpoint https://ton.nownodes.io/getAddressBalance
curl -L \
--url 'https://ton.nownodes.io/getAddressBalance?address=text' \
--header 'api-key: YOUR_API_KEY' \
--header 'Accept: */*'This is the exact kind of interaction that powers most TON wallets: calling RPC methods to fetch live data and display it to users instantly.
Best Practices for TON RPC Integration
When connecting your wallet to TON through NOWNodes, make sure to:
- Keep your API key safe (store it on the backend, not in client-side code).
- Test your integration on testnet before going live.
- Handle errors gracefully so your users always get clear feedback.
Following these steps ensures that your wallet remains both secure and reliable.
Final Thoughts
Integrating TON RPC into your wallet is much simpler than running your own TON node. With NOWNodes, developers get instant access to fast and scalable RPC endpoints, allowing them to focus on building user-friendly wallet experiences instead of worrying about infrastructure.
Whether you’re creating a lightweight mobile wallet or a full-featured browser extension, using TON RPC via NOWNodes ensures your app can interact with the TON blockchain quickly, securely, and at scale. Try it today by registering on NOWNodes and connecting your wallet to TON RPC within minutes.
