### Abstract

This is a mechanised specification of the WebAssembly language, drawn mainly from the previously published paper formalisation of Haas et al. Also included is a full proof of soundness of the type system, together with a verified type checker and interpreter. We include only a partial procedure for the extraction of the type checker and interpreter here. For more details, please see our paper in CPP 2018.
