Smart contracts are versatile instruments that can not only facilitate and verify transactions in financial services, but also track the movement of physical goods and intellectual property. Security and correctness are essential for smart contract technology, because contracts possess the authority to allocate high-value resources between complex systems and are, for the most part, autonomous. Smart contracts have been the targets of widely publicized attacks, some successful in inflicting considerable financial damage.

This workshop is broadly focused, and considers all approaches to analyzing smart contracts, static and dynamic. It covers, but is not limited to:
- Analysis-based vulnerability discovery (e.g. heuristics-based static analysis, fuzzing)
- Sound analysis (e.g. model checking, temporal logic)
- Code optimization (e.g. code-size reduction, gas-cost estimation)
- Code understanding (e.g. decompilation, reverse engineering)
- Code monitoring (e.g. debugging, fault detection)
- Intermediate representation (e.g. design, specification)
- Application-specific analysis (e.g. DeFi modeling)

The workshop aims to bring researchers and practitioners together and will promote open and reproducible research. Papers improving existing tools or proposing new ones are encouraged.

The workshop will be co-located with ISSTA 2021.

# Submission Information

Papers should be submitted in ACM Conference format, and are limited to 8 pages, including references. Papers can be submitted via EasyChair. Submission is not blinded. We particularly welcome papers focused on practical, open source tools for contract analysis.

All authors should use the official “ACM Master article template”, which can be obtained from the ACM Proceedings Template pages ( https://www.acm.org/publications/proceedings-template ). Latex users should use the “sigconf” option as well as “review” (to produce line numbers for easy reference by the reviewers). To that end, the following latex code can be placed at the start of the latex document:

\documentclass[sigconf,review]{acmart}

** Short Paper Option ** In addition to full 8 page papers, we also will accept New Ideas papers for promising ideas that might not have the experimental validation expected in a full paper. These papers will receive the same presentation and discussion time as full papers, in order to focus the workshop on novel, but relatively unexplored, ideas. To submit a new ideas paper, simply submit a paper of 4 or fewer pages.
