We propose a novel way of embedding functional smart contract languages into the Coq proof assistant using meta-programming techniques. Our framework allows for developing the meta-theory of smart contract languages using the deep embedding and provides a convenient way for reasoning about concrete contracts using the shallow embedding. The proposed approach allows to make a connection between the two embeddings in a form of a soundness theorem. As an instance of our approach we develop an embedding of the Oak smart contract language in Coq and verify several important properties of a crowdfunding contract. The developed techniques are applicable to all functional smart contract languages.
