TON executes contract logic through asynchronous messages. A single transaction can trigger a chain of messages between contracts, which may be processed across several blocks while preserving a defined order within each chain.

STONfi uses this model when executing complex routes. A swap can generate messages that move funds into a pool, perform internal conversions, update farming positions and return the final result. Each step is a message to a specific STONfi contract, and the whole chain either completes or reverts as one unit.

Applications using the STONfi SDK only see the initial request and the final confirmation. The asynchronous sequence in between is handled by the network and the contracts, remaining visible for on chain analysis but hidden from the everyday user flow. $GRAM $DOGS
