Abstract Silver nanowire (AgNW) networks hold great promises as next‐generation flexible transparent electrodes (FTEs) for high‐performance optoelectronic devices. However, achieving large‐area AgNW network with low sheet resistance, high optical transmittance, and a smooth surface remains grand challenge. Here, we report straightforward cost‐effective roll‐to‐roll method that includes interface assembly/wetting‐induced climbing transfer, nanowelding, washing processess to fabricate ordered layered uniformity. By manipulating the stacking number of interfacially assembled monolayer, can precisely tailor balance transparency conductivity electrodes, an exceptional Figure Merit (FoM) value 862. Moreover, structure enhances smoothness, compared randomly arranged structures. To highlight potential these in devices, successfully employ them highly sensitive strain sensors, touch screens, smart windows. Overall, this work represents substantial advance toward FTEs over large areas, opening up exciting opportunities development advanced image
