Additional Resources for Understanding End-User Perception of Transfer Risks in Smart Contracts

This contains further resources for the work titled "Understanding End-User Perception of Transfer Risks in Smart Contracts", which is set to appear in CHI 2025. This work details an investigation into user understanding of transfer risks in ERC-20 blockchain smart contracts. An example transfer risk is a user being unable to transfer due to their account being blacklisted by the owner of the contract. A large portion of this work focuses on the most popular Ethereum smart contract (USD Tether). This details responses to a 110-participant survey on smart contract users, establishing their knowledge of transfer risks and various other perceptions. Included also are the results of statistical tests on these responses, the follow-up message to the respondents and more. Another portion of this work investigates the presence of transfer risks in other top ERC-20 contracts. The results of this investigation is also found here. This also includes results of blockchain analytics to establish the top ERC-20 addresses, as well as code used for processing.
