About us
What ETH Cali is
The Ethereum community of Cali and the Colombian Pacific. A non-profit foundation that teaches, researches and builds with Ethereum — and lends out the hardware so other people can do the same.

Every figure is computed over the same list of 441 wallets on Dune: the ones that picked up a POAP or an ETH Cali NFT at one of our events.
See the onchain metrics on Dune →What we do
Four things, and each one has a page where you can check it.
We teach
Open meetups and workshops across six universities in the city. Free, always, and with nothing you need to know before you arrive.
The learning path →We run hackathons
With EAG, HashKey Chain, Base, Uniswap and ETHGlobal. The latest was the Ethereum Builders Tour: 25+ hackers in under 48 hours.
Every hackathon →We lend the hardware
Projectors, sound, cameras and chairs. Free, and you do not have to be part of ETH Cali to ask — that is what we bought them for.
See the inventory →We govern on chain
The treasury is a 3-of-5 Safe on five chains, decisions are voted on Snapshot, and every address on this site links to its explorer.

Our mission
Education
We teach Ethereum from zero, in universities and in open meetups. Knowledge is shared, not hoarded.
Research
We test what has no manual yet — L2s, identity, stablecoin payments — and publish what we find.
Building
Hackathons, deployed contracts and applications that run. What comes out of here can be opened and used.
Community
None of the above is done alone. Cali and the Pacific building together, with the door open.
Who does it
Twenty people across founders, core, elite, contributors and volunteers. Every one of them started as someone who turned up to a meetup.
