Inferring Needless Write Memory Accesses on Ethereum Bytecode (Extended Version)
Elvira Albert, Jesús Correas, Pablo Gordillo +2
Efficiency is a fundamental property of any type of program, but it is even more so in the context of the programs executing on the blockchain (known as smart contracts). This is b…
Analyzing Smart Contracts: From EVM to a sound Control-Flow Graph
Elvira Albert, Jesús Correas, Pablo Gordillo +2
The EVM language is a simple stack-based language with words of 256 bits, with one significant difference between the EVM and other virtual machine languages (like Java Bytecode or…
GASOL: Gas Analysis and Optimization for Ethereum Smart Contracts
Elvira Albert, Jesús Correas, Pablo Gordillo +2
We present the main concepts, components, and usage of GASOL, a Gas AnalysiS and Optimization tooL for Ethereum smart contracts. GASOL offers a wide variety of cost models that all…
SAFEVM: A Safety Verifier for Ethereum Smart Contracts
Elvira Albert, Jesús Correas, Pablo Gordillo +2
Ethereum smart contracts are public, immutable and distributed and, as such, they are prone to vulnerabilities sourcing from programming mistakes of developers. This paper presents…
Running on Fumes--Preventing Out-of-Gas Vulnerabilities in Ethereum Smart Contracts using Static Resource Analysis
Elvira Albert, Pablo Gordillo, Albert Rubio +1
Gas is a measurement unit of the computational effort that it will take to execute every single operation that takes part in the Ethereum blockchain platform. Each instruction exec…
EthIR: A Framework for High-Level Analysis of Ethereum Bytecode
Elvira Albert, Pablo Gordillo, Benjamin Livshits +2
Analyzing Ethereum bytecode, rather than the source code from which it was generated, is a necessity when: (1) the source code is not available (e.g., the blockchain only stores th…
