Good vibes, cryptography & code. @hashcloak
Joined February 2023
This was super fun to work on ๐ค
Building upon our previous work on ZK verifiers in Sway, we've built a Ultrahonk verifier in Sway. You can now write @NoirLang programs that target the @fuel_network ecosystem. Check out @Haven_Hn_ which uses our new verifier to provide scalable, private transactions on Fuel.

For anyone interesting in learning zk proofs, I built a web app that lets you "debug" STARKs end-to-end. You can write simple programs, generate/verify STARKs, and explore the execution traces and constraint polynomials. Link in 1st response.

A year in HashCloak ๐
1/ In 2025, HashCloak got out of its shell and started being more public about our work with our clients. Here are some highlights on what weโve (publicly) worked on this year ๐งต

Another super interesting app built on the @primus_labs zkTLS network and @aztecnetwork smart contracts, enabling a private on-ramping flow fully on-chain, powered by the DVC mode developed with @hashcloak.
How do you sell $ZEC for fiat P2P without trusting the counterparty? Private bridge to @aztecnetwork, escrow ZEC, buyer proves payment via zkTLS, auto-release. Built for Zypherpunk hackathon using @primus_labs

What we like to do at an @hashcloak onsite
The @hashcloak team won @aztecnetwork's infrastructure @ETHGlobal Buenos Aires ๐ฅณ Y'all would not believe the lore around this. Expect a thread soon ๐ https://t.co/4ZUZUnjTp5

If only there was a technology that could prevent this!
JPMORGAN CHASE, CITI AND MORGAN STANLEY ARE AMONG THOSE THAT HAVE BEEN NOTIFIED BY SITUSAMC THAT THEIR CLIENT DATA MAY HAVE BEEN TAKEN- NYT

Apparently overexcited for NoirCon, I showed up too early for the first time this Devconnect week ๐

I thought @badcryptobitch just really liked tea, turns out she was going to TEE related side events

The most historic side event of devconnect was decentralized.
BREAKING: Aztec just shipped the Ignition Chain, the first fully decentralized L2 on Ethereum. This launches the decentralized consensus layer that powers the Aztec Network. https://t.co/nYyD7cykz2 ๐งต

CatioCrypto, the cryptography school in Spanish affiliated to LatinCrypt 2025, was a success! Thanks to @octaviopk for coordinating this with me, and to the speakers Armando Faz-Hernandez, Valerie Gilchrist, and Eduardo Soria-Vazquez. Also, thanks to the LatinCrypt organizers.

Today weโre announcing our integration with @aztecnetwork: โก๏ธ Bringing ๐๐ซ๐ข๐ฏ๐๐ญ๐ ๐๐ก๐๐ซ๐๐ ๐๐ญ๐๐ญ๐ (PSS) to the Ethereum ecosystem. Hereโs why this is a big deal ๐
