Testnet API

TON Center supports both mainnet and testnet environments for all API versions.

The testnet is ideal for development and testing. It mirrors the functionality of the mainnet but uses separate smart contracts and tokens with no real-world value.

Base URLs

Environment	API v2	API v3
Mainnet	https://toncenter.com/api/v2	https://toncenter.com/api/v3
Testnet	https://testnet.toncenter.com/api/v2	https://testnet.toncenter.com/api/v3

Simply replace the base URL in your requests depending on your environment.

You can check out the Testnet API in the API playground for v2 and v3 by selecting the testnet URL from the dropdown menu.

Usage Notes

• No real TON is needed on testnet.
• You still need an API key for higher rate limits, get one here.
• Ideal for testing wallets, contracts, and integrations without affecting live data.
