Underground Meetup #1 Buenos Aires Farewell
1SEC is a private group where some of the sharpest minds in Web3 swap alpha, war stories and pain.
Tomorrow we take it offline, right here in Buenos Aires.
No stage. No slides. No sponsors.
Just researchers, builders and security people hanging out before everyone flies back home.
It’s our first 51SEC gathering outside Brazil, and the perfect send-off after an insane week of Devconnect and Stark events in Argentina.
If you breathe development, audits, exploits, formal verification, infra, ZK, blue team, or red team, this is where you want to be.
If you're curious and want to break into these topics, this is the safest room you’ll ever walk into.
Come for the people. Stay for the conversations. Leave with new skills and new friends.
What to Expect
• Raw, unfiltered discussions about real exploits, near-misses, weird bugs, and the kind of engineering challenges nobody posts publicly.
• Stories from audits, contests, CTFs and live production incidents, the stuff that actually makes you a stronger engineer.
• Cross-pollination between Brazilian security builders and the broader Latam + global ecosystem.
• Zero marketing. Zero shilling. 100% signal.
If you’re a dev hungry to level up, or someone exploring security, ZK, infra or verification, this is the room you want to be in.
Everyone pays their own tab. No free bar, no free dinner.
This is an informal meetup inside a normal place, so keep OPSEC in mind and respect the venue.
