TLDR
At Devconnect Buenos Aires, about 80 Ethereum security practitioners met to identify what’s needed to protect Ethereum at trillion-dollar scale. Their big takeaway: the toughest gaps are often coordination, clear trust assumptions, and sustainable security work, not just cryptography. 
Key Points
Security should be an ongoing practice, not a one-time milestone—and “audited” does not automatically mean “secure.”
Better coordination across Ethereum layers is needed, especially between L1 and L2 teams, wallets, and interoperability projects.
Users need clearer information about what they’re trusting, from bridges and wallets to RPC providers and frontends.
The ecosystem needs lasting support for shared security tools, monitoring, standards, and other public goods.
Participants want practical follow-up: open standards, better dashboards, implementation guidance, and continued cross-layer work.
In-depth summary
The Ethereum Foundation and Secureum TrustX organized Trillion Dollar Security Day to assess security across Ethereum’s stack and identify actionable priorities. Around 80 practitioners joined breakout discussions spanning protocol layers, wallets, onchain security, interoperability, privacy, infrastructure, and offchain security. The sessions aimed to understand current risks, align on near-term action, and improve long-term coordination.
Across the discussions, participants highlighted recurring challenges: security assumptions are often poorly communicated, critical tooling and public goods struggle to get sustainable funding, and incentives or coordination can create risks even where the cryptography is strong. Suggested steps included improving L1–L2 coordination and EIP ownership; creating more open wallet-signing collaboration and clearer wallet security information; funding open-source analysis tools and improving DeFi risk visibility; and making bridge trust assumptions easier for users to compare.
The conversations also covered privacy and the less-visible parts of the stack. Privacy adoption is held back by UX, cost, infrastructure, and hardware limitations. Frontend compromises, DNS and RPC weaknesses, cloud dependence, and software supply-chain attacks were raised as important risks, alongside the need for better offchain security frameworks and support for public-good providers. Participants valued the in-person discussions and called for future work on shared standards, tools, and practical guidance. The event’s findings will feed into the Ethereum Foundation’s One Trillion Dollar Security initiative.
ELI5
Ethereum has many parts, and keeping it safe means checking all of them—not just the code. The people at the event said teams need to work together better, explain risks more clearly, and keep funding the tools that help everyone stay safe. 
Writers main point
Supporting a trillion-dollar Ethereum economy requires continuous, coordinated security work across the whole ecosystem, with clear standards and sustainable support for the people and tools doing that work.
