1. 1. Smart Contract Maturity Model

   Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Jordy Jordanus Cornelius van Raalte; [2023]
   Nyckelord :smart contracts; maturity models; smart contract problems; blockchain; proof of work; proof of stake; smart contract implementation problems; smart contract use cases; smart contract challenges; smart contract opportunities; bitcoin; Ethereum; Hyperledger fabric; Codra; Ethereum smart contracts; smart contract platforms; maturity models and CMMI maturity model;

   Sammanfattning : A smart contract is a recently emerging technology which enables agreement to be automatable by computers and enforceable by legal enforcement or tamper-proof execution of code. A majority of smart contracts are run on the blockchain which enables smart contract transactions without a central authority. LÄS MER

3. 2. Identifying Threat Factors of Vulnerabilities in Ethereum Smart Contracts

5. 4. An initial investigation of Automatic Program Repair for Solidity Smart Contracts with Large Language Models

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Erik Cruz; [2023]
   Nyckelord :Automatic Program Repair; APR; Large Language Models; LLM; Smart Contracts; Smart Contract Audit; Chat GPT; Cybersecurity; Automatisk Lagning av Kod; Stora språkmodeller; Smarta Kontrakt; Granskning av Smarta Kontrakt; Chat GPT; Cybersäkerhet;

   Sammanfattning : This thesis investigates how Large Language Models can be used to repair Solidity Smart Contracts automatically through the main contribution of this thesis, the Transformative Repair Tool. The Transformative Repair Tool achieves similar results to current state-of-the-art tools on the Smartbugs Curated Dataset and is the first published tool that uses Large Language Models to repair Solidity Smart Contracts.
