There's no fixed maximum trading size on Bebop.
The maximum trading size is theoretically limited by the combined inventory across all trading venues that solvers plugged into Bebop can access.
In practice, JAM trades limitations are more nuanced depending on solvers’ algorithms and whether or not they choose to fulfil certain intents.
For stablecoins and majors, we regularly handle trades of several million dollars. Our largest JAM trade as of October, 2025 was a $17M trade from wstETH to ETH.
