This provides the artifact of our end-to-end formal verification of the Ethereum 2.0 deposit contract written in Solidity.
[NOTE: The deposit contract had initially been written in Vyper, but later it was reimplemented in Solidity. The formal verification of the initial Vyper implementation can be found at here].
