Few people have thought about what various $TON network projects are currently built on. It is now used by wallets, bots, gaming applications, and other services that want to integrate reliable exchanges and work with pools without launching their own DEX. We are talking about the STONfi SDK, which was launched back in 2023.

This was followed by the release of SDK 2.0, which established it as the standard for the $TON ecosystem. Support for mintless tokens appeared — a new Jetton model that can be distributed without a smart contract and without commissions. Minting only occurs after the user's first action, which greatly simplifies the launch of projects.

The SDK also added a deadline for transactions, meaning that if a transaction hangs for more than 30 minutes, it is automatically canceled. This is useful for the network itself, as it removes unnecessary load.

And now it turns out that the STONfi SDK has become the technical foundation for the new $TON DeFi layer. Indeed, many proven applications use this very tool, and among the major applications, I would like to highlight Tonkeeper, TON Wallet, and Tonco.
