In any network with active exchanges, and even in the fastest network, $TON , there is a subtle but important problem: frozen transactions. When the price has already changed, liquidity has disappeared, and the swap is still trying to execute under the old conditions. For the user, this looks like uncertainty and unnecessary risk, especially in times of volatility.

STONfi approached this issue from an infrastructure perspective. A transaction deadline mechanism was added to the SDK. Its meaning is simple: the exchange is limited in time in advance. If the conditions do not match or the route cannot be executed on time, the transaction is simply canceled rather than left hanging in anticipation of an unknown outcome.

In practice, this significantly changes the experience of working with DeFi across the entire $TON network. Users no longer have to worry that after a few blocks, they will receive a result that no longer makes sense. The swap either proceeds immediately according to the expected logic or does not happen at all. No surprises and no manual control. Such things rarely make it into high-profile announcements, but they are what build trust in the platform.
