### Using Protocol Nodes
Drag a protocol node onto your canvas and connect it between token positions. Each protocol node requires configuration, click it to open the configuration panel where you can select markets, tokens, or operation types depending on the protocol.
Protocol nodes automatically handle the on-chain interactions when your strategy executes, so you can focus on designing the flow rather than managing transaction details.
