01The product
Guardrails without taking the keys.
As co-founder and CTO, I worked on an Ethereum Layer 2 built with Arbitrum Orbit and a non-custodial smart wallet using passkeys, account abstraction and permissioned access to applications.
02The build
Infrastructure from a moving office.
Much of Kinto was built while travelling through Japan, Korea, Singapore, Taiwan and the rest of Asia with my girlfriend and my friend and co-founder Ramón Recuero. The office changed more often than the time zone in the calendar.
03The ending
The company closed. Here is what happened.
In July 2025 an exploit hit a legacy token proxy on Arbitrum. Kinto’s L2, wallets, user assets on Kinto and core infrastructure were not breached. The team restored operations and attempted a recovery, but further funding and market conditions made continuation impossible. Kinto closed in September 2025.
