Hardening Smart Contracts with Hardware Security
Trusted hardware is not your enemy – as threats against cryptocurrencies are evolving (from dumb malware sweeping private keys to smart attackers attacking the presentation layers of smart contracts), we’ll review during this presentation a short history of trusted hardware, how Open Source code can be designed today on modern trusted execution environments to provide a flexible and auditable environment to delegate the security critical parts of smart contracts, and the security compromises made when dealing with the opaque features of trusted hardware.
Ledger SGX enclave - (un)popularity assessment and the way forward
An overview of the new developer features available for Ledger Nano S Ethereum application, including the validation of an arbitrary smart contract call on screen and how to design a Dapplet on a Nano S to assist the security of Dapps.
DeFi Can’t Move Forward Without Clear Signing: Let Me Change Your Mind
Blind signing has been the default way of signing transactions in DeFi, but let’s be honest: as an industry we are shooting ourselves and our users in the foot by continuing to throw caution to the wind. We want to make it easy to implement clear signing for every dAapp, minimizing the work required for developers to make the ecosystem more approachable and secure. Blind signing is an existential threat to what we do, it’s time to change it, and we need your help.
Ethereum Security
Martin Swende gives their talk on Ethereum Security.
Evolution of Smart Contract Security in the Ethereum Ecosystem
A lot has changed in the smart contract development ecosystem in the year since DEVCON2. Our perspective as leaders of the smart contract security community OpenZeppelin shows us that the industry is maturing. We give a brief overview of how security patterns and practices have evolved in the past months, dive into some details of recent developments, and talk about promising projects and their plans for the future.
The Melon security approach
Melonport is striving to build a vibrant and successful developer ecosystem of Melon module builders. An important part of that ecosystem is the security and behaviour of smart contracts that make up Melon modules as well as how they interact with the Melon core and each other. In this presentation, we’ll demonstrate our ongoing technical efforts to assist Melon module developers in creating safe, secure smart contracts and touch on the importance of getting the auditing process right and how others can learn from our experience.
Vulnerability Coordination and Incident Response in a Decentralized World
There’s one question that every team of core blockchain developers has discussed at least once: what are we going to do when a critical vulnerability in our software is surfaced? By definition, everything we create is likely to include a vulnerability or code flaw and the difficult legal, ethical, and business issues arise when bugs show up in code. While decentralization does not require us to reinvent the first principles security, it does force us to challenge ourselves to manage significant complexity to reduce harm to those who depend on our code. This talk will discuss the CosmosCERT as a model for how teams can successfully coordinate vulnerabilities and respond to incidents in decentralized environments using on-chain governance mechanisms in a way that ensures stakeholders have a dedicated emergency response capabilities ready to go when the worst happens.
Debug First, or Regret Later: an Arsenal of Tools can Build Solid Ethereum Foundations
Building secure and reliable smart contracts requires a robust testing and debugging arsenal. This talk provides a comprehensive and up-to-date overview of essential tools in the Ethereum ecosystem. Learn how to effectively integrate these tools into your development workflow from the start. We'll explore popular options, their strengths, and how to combine them for maximum efficiency. Discover best practices for writing comprehensive tests, identifying and fixing bugs, and ensuring code quality
Batched Bonding Curves: Grieving DEX Frontrunners
It's been widely publicized that front-running is rampant across decentralized exchanges. Billy Rennekamp describes the technique developed to stop the parasitic behavior by using batched orders in tandem with bonding curves and how it's being used in a new fundraising app by Aragon Black.
(Defense Against) The Dark Arts - Contract Runtime Mutability
Smart contracts are no longer guaranteed to have immutable runtime code, and can be redeployed with new code using a variety of methods involving the CREATE2 and SELFDESTRUCT opcodes. In this presentation, we will investigate how this is done and how to protect against malicious mutable contracts. We will also explore ways these new techniques can be applied in order to enable new use-cases and to improve the user experience.
