This repository contains a specification, implementation, and verification (in Isabelle) of the Solidity ABI encoder and decoder.
The repository is structured as follows:
- ABI types and other basic notions:
AbiTypes.thy - Isabelle syntactic sugar for writing ABI types:
AbiTypesSyntax.thy - Constructs for error messages used in encoder and decoder implementations:
Ok.thy - Formal Solidity ABI encoding specification:
AbiEncodeSpec.thy - Encoder implementation:
AbiEncode.thy - Decoder implementation:
AbiDecode.thy - Encoder correctness theorems:
AbiEncodeCorrect.thy - Decoder correctness theorems:
AbiDecodeCorrect.thy - "Round-trip" theorems about decoding encoded results (and vice versa):
Inverses.thy - Isabelle files containing test inputs for encoder and decoder:
AbiTest.thy
